Integrated Water Resources Management (IWRM)

Everywhere in the world, water resources are essential for socio-economic development and a healthy environment, and as a critical component to growth, poverty reduction and equity. Nowhere is this more apparent than in African nations, where governments endeavour to manage their water resources in the face of climate change and with limited financial resources. CARES can offer solutions to the most pressing challenges of the increasing demand for domestic, agricultural and industrial water, driven by insight, innovation and many years of global experience, and by integrating the solutions and optimising the benefits to all water users.

The growth in African populations inevitably leads to increased competition for scarce water resources, between the critical uses for food production, domestic consumption and industrial processes, including power generation. Ministries and agencies tasked with managing water resources are faced with the key challenge of protecting and allocating water for these various uses, whilst private companies and individual users have a responsibility to minimise wastage.

CARES aims to provide technical assistance to enable all stakeholders to effectively respond to the challenges of managing their water resources, be that for a rural drinking water project, large scale catchment management or irrigation scheme, hydropower development, flood alleviation and erosion control measures, or for the protection of the aquatic ecology.

CARES can provide efficient and sustainable engineering, management and environmental solutions, aimed at optimising the natural flows in rivers and groundwater sources and maximising supplies to the competing demands for water. CARES take an integrated approach to developing these solutions, combining our expertise and knowledge in the key services relevant to water resources, as follows:

  • Policy, law and regulation
  • GIS, remote sensing and spatial data analysis
  • Atmospheric, surface and ground water hydrology
  • Water resource systems modelling
  • Bio-chemical processes (Storage and transformation in catchments, rivers and water bodies)
  • Financial and economic analysis of natural resources.
  • Demand analyses:

- Domestic (Population growth, consumption patterns and willingness to pay)

- Industrial (Manufacturing process and hydropower generation targets)

- Agricultural (Crop evapotranspiration, Irrigation efficiency and Produce handling)

- Ecological and environmental water requirements

- River, lake and marine transportation needs

Solutions may include engineering interventions, such as the design of dams, canals or treatment plants, or institutional reforms, development and implementation of strategies for pricing or water permitting and capacity building for stakeholders.

Hydraulic Structures, Flow Measurement & Control

Effective water management in catchments and networks, whether for clean water supply, flood control, wastewater effluent discharging or environmental mitigation, requires the ability to measure and control flows in open channel watercourses and closed conduits, and often this involves the use of hydraulic structures and instrumentation. CARES’ experienced engineers can identify the specific needs and constraints, consider the technical and financial feasibility of options, and provide the detailed design and construction supervision for many types of hydraulic structures, measurement and control devices. CARES’ clients can depend upon our experience for exceptional analysis and design, covering aspects such as fluid mechanics, fluid control circuitry, pumps, turbines, hydropower, computational fluid dynamics, stream flow measurement, and river channel behaviour and erosion.

Hydraulic structures that CARES’s staff have worked on include dams and their appurtenant structures (e.g. inlets, weirs and spillways), raw water and effluent pump stations and pipelines, open channels and structures for irrigation and drainage, including checks and head regulator gates, measurement flumes, aqueducts and culverts, as well as flood walls and revetments, and other erosion control measures.

Wastewater, Sewerage and Stormwater Drainage

With the rapid rate of urbanisation and the impacts of climate change, wastewater and stormwater management requires more complex engineering and environmental solutions to maximise the benefits of investments made by Clients in their wastewater, sewerage and stormwater drainage systems. CARES have expert technical advice and established modelling and design teams, with experience in many technologies and situations that can meet this demand. CARES and their specialist staff have a significant track record of wastewater and stormwater modelling, analysis and design, from local drainage designs through to major stormwater infrastructure schemes, and have established processes and specifications to ensure an efficient design process and cost-effective construction for our Clients. We deliver these efficiencies through automated design procedures and project management systems that ensure technical quality and the achievement of key milestones in the schedule.

Urban development rarely follows the expectations of wastewater and stormwater masterplans, with changes frequently being made without the utility providers’ knowledge or approval. As a result, the rehabilitation, extension and modification of existing wastewater and stormwater services, and to adjacent structures and buildings, can be fraught with difficulties and a comprehensive approach to problem solving is required. CARES possesses the necessary expertise to address a diverse range of wastewater and stormwater issues, underpinned by geotechnical, civil and hydraulic expertise, and catchment management planning, water infrastructure design, consenting and construction supervision experience.

We work on all types of wastewater and stormwater infrastructure, including:

  • Natural watercourses, streams and rivers
  • Man-made drainage systems (open channels and below ground)
  • High-hazard tailings dams and reservoirs
  • Conventional and non-conventional wastewater treatment facilities.

CARES takes great pride in its ability to develop innovative, costeffective, practical and sustainable environmental solutions to manage wastewater and stormwater for a wide range of Clients, and seeks to incorporate urbanisation impacts, community-based flood management, ecosystem protection, ‘natural’ system replication and water quality management into all projects. Services rendered include:

  • Stormwater and wastewater investigations
  • Hydrologic data collection and analysis (modelling of rainfall and runoff)
  • Conceptual and strategic planning for urban wastewater and stormwater master plans
  • Catchment analysis and reservoir modelling
  • Floodplain and flood hazard mapping

Our training services include seminars and workshops, brochures and electronic communications, consultations and policy reform processes.

Increasing energy costs and carbon emissions are key drivers in the quest for sustainable, low carbon energy supplies. CARES offer a wide range of investigation, analysis and consultancy services for the sustainable/renewable energy sector, from initial options appraisal through to front end engineering. We also advise on the impacts of new developments on carbon emissions, to facilitate decision making by local and national governments, investors and other stakeholders.

Project Appraisal & Feasibility Studies

CARES offers integrated engineering and environmental services for the identification, development and appraisal of projects, including feasibility studies covering all aspects of technical, financial and economic suitability, risk assessment, and the identification and mitigation of any environmental and social constraints to development interventions. CARES’ wealth of experience covers various sectors, including transport, infrastructure and pipelines, including constraints such as social, ecological, geotechnical and hydrological (flood risk).

CARES provide technical and commercial appraisal and feasibility services for clients, lenders and investors, based on a thorough understanding of each project, at all stages from inception through to implementation, and by assessing the technical feasibility of intended activities and investments, and mitigating any risks, to add value to the project, maximise the benefits to all stakeholders and minimise the costs. We tailor our comprehensive feasibility analysis for each project, categorising the technical risks in context of the overall risk profile, enabling clients to take a view on the acceptability of each item.

CARES’ approach to appraisals and feasibility studies considers sustainability as a key focus of the assessments, with a view to understanding both the environmental needs and the views of all interested parties, such as local communities; it encompasses many aspects including:

  • Technical, environmental and social issues
  • Project economics
  • Regulatory requirements
  • Commercial performance
  • Operational requirements
  • Residual life

The purpose of a feasibility assessment is to support the process of decision making and determine whether a project can proceed to the next detailed design phase. The evaluation and analysis is based on two key criteria: technical achievability and cost constraints, and considers alternatives for achieving the same desired project outcome, to narrow the scope of the project and identify the optimum scenario. Therefore it is very important to have engineers, environmental and social scientists, finance analysts and economics with good experience and judgement to be involved feasibility studies, drawing on their breadth and depth of experience.

CARES staff have a wealth of expertise from around the globe and across a wide range of sectors, having completed feasibility studies and project appraisals in rehabilitation and development of irrigation, flood alleviation and bulk water supply schemes, commercial and residential developments, coastal defences and docks, as well as hydropower, wastewater and sanitation, and rural development.

Rural Development, Food Security & Poverty Reduction

Food insecurity remains prevalent in much of Africa, where hunger and malnutrition can undermine the achievement of development objectives in other sectors, such as education, as well as providing an environment for insecurity. CARES believes that agriculture is an integral part of rural development, where agricultural production is the main source of employment and income, and the major focus for development should be to reduce poverty through agricultural research, infrastructure and management, fully integrated with investments to tackle the other problems of rural areas, such as water supply, sanitation, health, education, power and transport.

CARES works hand in hand with its clients to help achieve their development goals and build the capacities of rural people to ensure long-term sustainability, involving them at every stage of a development project to discuss the issues and
agree the way forward. CARES believes that such a participatory approach, whilst requiring greater commitment from all parties, ensures that the process of development is community-owned and creates opportunities for the local people.

The key services that CARES can provide in rural development, food security and poverty reduction include the following:

  • Analysis, research, strategy and policy for rural development, food security and poverty reduction
  • Design and review of food security and rural development projects and programmes

Groundwater Investigations, Development & Mechanisation

CARES have the technical capability and understanding to deliver hydrogeological studies, including groundwater monitoring, groundwater resource assessment, conceptualisation, groundwater flow, transport modelling and field investigations. We work with specialist hydrogeologists and drilling contractors on all aspects of groundwater science and groundwater resource management, based on a detailed understanding and experience of the key issues involved.

CARES services include:

  • Water resource assessment
  • Catchment management
  • Aquifer databases
  • Artificial recharge/Aquifer Storage and Recovery
  • Permitting: abstraction and discharge
  • Groundwater risk assessment
  • Groundwater control and dewatering
  • Low flow investigations
  • Borehole design and installation
  • Groundwater modelling
  • Groundwater source evaluation
  • Groundwater sewer infiltration
  • Drought permits and monitoring

CARES staff have experience of investigating many of Africa’s aquifers and have access to local knowledge and hydro-geological databases for many regions on the continent.

Groundwater Investigation, Development & Mechanisation
Groundwater Investigation, Development & Mechanisation

Artificial recharge is often specified to manage aquifers and CARES also considers a cautious approach with new technologies, such as Aquifer Storage and Recovery (ASR) to utilise the same point for injection and abstraction, to develop aquifers that were previously unlikely sources.
Permitting for water abstraction and discharge can be difficult for clients unfamiliar with local regulations and laws, but CARES can help by preparing compliant applications on behalf of clients, obtaining approvals promptly, renewing on time and avoiding difficult consent conditions that may add to operational costs.

CARES can also undertake groundwater risk assessments to support environmental permitting applications for projects ranging in size and complexity from household soakaways through to complex landfill sites, including quantitative risk assessments and infiltration system risk assessments.

Modern underground construction and deep mining excavations require accurate predictions for dewatering rates and methods of control, to minimise the significant costs and mitigate the environmental constraints. CARES draws on the experience of staff and specialists, working closely with the client to determine appropriate levels of assessment and cost effective solutions for individual sites.

CARES staff have experience of designing and supervising the drilling, installation, testing and mechanisation of boreholes, and we have relationships with highly skilled hydrogeologists to provide the very best advice on borehole siting and design. Our design and supervision staff aim to get it “right first time”, minimising capital and recurrent costs and preventing unpredictable and inadequate performance.

We believe in developing non-adversarial relationships with contractors and close liaison with environmental regulators to obtain appropriate consents and complete construction on schedule.

CARES applies appropriate modelling tools to provide practical answers to a wide range of groundwater problems to optimise and plan the management of water resources, including:

  • Licence application/renewal/revision
  • Conjunctive use schemes
  • Climate change assessment
  • Drought planning and low flow assessments
  • Source feasibility
  • Environment impact assessments
  • Contaminant transport/saline intrusion
  • Catchment management

If borehole performance is monitored and appropriate maintenance regimes are followed, then groundwater sources should be long-term assets. However, sources may occasionally benefit from rehabilitation, particularly those that have been dormant. Failures may be related to water quality (e.g. microbiological or chemical contaminants), excessive pumping of sand, structural failure (e.g. collapse) or progressive loss of performance (e.g. encrustation or biofouling), and understanding the borehole history, current condition and the aquifer characteristics are key to identifying the issues and developing an appropriate rehabilitation/maintenance regime. CARES groundwater specialists can undertake borehole condition assessment, apply best practice and evaluate the rehabilitation/maintenance cost benefit. This would involve a visual inspection to confirm structural integrity and sanitary seal, and further testing by CCTV downhole condition survey and pump testing.

Groundwater resources can be at risk from leaking wastewater sewers and rising mains, but it can also infiltrate gravity sewers resulting in increased flows and treatment costs, and the risk of untreated discharges to the environment. CARES experts can undertake risk assessments in Safeguard Zones, to understand the risks of sewer leakage and infiltration, and develop options for mitigation.

Hydraulic Modelling & Verification

Hydraulic modelling enables accurate estimation of water levels and flood extents for open watercourses and closed conduit drains, water pressures in pipelines and distribution networks, and dispersion of pollutants in an aquatic environment. Detailed and site-specific modelling can be used to refine designs and materials, saving money for the Client, and to assess risk parameters, such as flood flow velocities, water levels and pipeline zone pressures, to protect assets, operators and the general public.

CARES has been a leading provider of hydraulic modelling services, utilising state-of-the-art hydraulic modelling technology to model flow velocities, depths and dispersion into the environment in navigation channels in West Africa. We provide world class modelling services through all stages, from performing the scoping study, data collection and surveys, through to model building and verification of the developed models. We create customised model systems, in varying degrees of complexity and size, to allow our designers and Clients to explore and identify hydraulic constraints, test and substantiate engineering concepts and develop feasible and cost effective solutions.

Our modelling procedures are regularly reviewed in light of current research and development and we have access to licensed users for several third party models, to ensure we follow international best practice and use the best model to fit the project, adjusting the model to match the situation, rather than implifying the problem to fit an existing model.

For model builds and verification, CARES sources data from remote sensing and Geographic Information Systems (GIS), ground surveys and anecdotal
information supplemented by our experts, Clients, operations staff and the general public. To ensure that a model accurately represents the reality of a situation, it can typically be verified against a short term flow survey, comparing model results with actual flow depths, and making adjustments to the model to establish an acceptable correlation. Our open channel and pipeline modelling services include:

  • Hydraulic computer model development, calibration and simulation
  • Hydraulic structures design, analysis and modelling
  • Analysis and certification of pipeline controls and measurement systems
  • Flow measurement and hydraulic field services
  • Open channel velocity profiling
  • Third party witness testing and calibration
  • Flow meter installations
  • Pump cavitation damage inspections
  • Dam breach analysis and reservoir inundation modelling
  • Surface water and sewerage management planning
  • Drainage area plans.

If necessary, we can also commission, manage and analyse physical and numerical modelling and testing undertaken by specialised independent laboratories.

CARES experience of hydraulic analysis of pumps and distribution networks also includes the modelling of surge, to fully integrate the impacts of transient pressures and system operations into the overall design. Surge pressure transients are rapid changes in fluid motion in pipelines, also known as water hammer, which can lead to operational problems and catastrophic failure. Consideration of surge, in conjunction with system operations, is a key element in the design of pipelines to ensure safety and reliability, avoiding the movement of thrust blocks, entrainment of air and pollutants, and more serious risks of bursts or collapse of thin walled materials. When fully understood, the impacts of surge can be minimised and the assets protected by integrating surge protection measures into the design and by setting operations procedures (e.g. surge vessels/tanks/shafts, pressure and air release valves, and pump and motor set inertia and valve closure rate limitations).

Our clients include governmental bodies, municipalities, port authorities, contractors, investors and industrial companies. From specialist advisory services and expert opinion, to preliminary reviews, detailed modelling, feasibility study and detailed design, our proven capability means we can offer added value to our Clients in the water, wastewater and oil and gas sectors, wherever they or their projects are based.

Industrial, Fire Fighting and Domestic Water Supplies

Water is a resource with multiple uses and increasing demands, making it more valuable than ever and setting managers a complex set of challenges to use it efficiently and cost effectively, ensure availability for all business critical processes, emergencies and environmental needs, and provide adequate access to safe potable supplies. Using our knowledge and experience, CARES can work with water utility companies and other clients to meet these challenges, providing services at all stages of the water supply process, from groundwater and surface water source works, to treatment, distribution networks and storage. Our experience, monitoring and modelling, enable us to develop a comprehensive understanding of supply system performance, enabling leakages to be identified, critical infrastructure assets to be recognised and managed, water quality to be preserved and effective institutions to plan and implement O&M.

CARES can assist clients to build, verify and operate hydraulic models of its water supply networks and systems. Hydraulic modelling can be used as a planning tool at every stage of the project cycle to provide our clients with the information that they require to make key business decisions; it can be used as the basis for master planning and strategic studies, for feasibility analysis and for design of network extension or replacement works. Hydraulic models are used in design, to size water mains, locate reservoirs and pumping stations, and set pressure zones; and as real time operational tools, to monitor and control system operations, identify constraints and poor practices, and improve planning.

CARES and its consultants are able to offer a full range of specialist water services for industries, including:

  • System flow diagrams and hydraulics
  • Pipeline material, sizing and route selection
  • Site investigation and geotechnical analysis

Fire safety engineering, involving the reaction of people and infrastructure to fire and emergencies, helps protect lives and businesses. CARES applies international best practice, national regulations and modern techniques and technologies to develop innovative solutions that satisfy client and regulatory requirements, are cost-effective and sustainable with respect to available water sources. CARES ensures that access widths, hard standing, dedicated storage volumes, minimum flow rates and locations of fire hydrants are approved for each design with national fire services.

CARES approach to water supply projects is to work closely with the client to ensure complete sharing of knowledge to enhance the understanding of the existing infrastructure, its constraints and future needs, in order to develop the most cost-effective water supply system, resolving capacity constraints and assessing the impact of extensions.

To ensure that the most appropriate resources are utilised, at every stage between inception to completion, CARES draws upon its network of specialist consultants to assist in the planning, design, construction, commissioning and operation of water supply projects and pipelines.

Institutional Reform, Capacity Development & Policy

Ensuring good governance is vitally important to the sustainability of international development interventions by building capacity of institutions and government bodies to carry out their roles effectively and working with civil society to improve their stewardship of project infrastructure. The governance of water resources raises some unique challenges that requires clear focus, policy and strategy, in order to break the predominant cycle of capital investment, under-resourcing in operation and maintenance, leading to deterioration, reduced user confidence and income generation, and premature failure.

CARES provides training and capacity building programmes to promote the development of capable, accountable and responsive governance
and regulatory bodies, together with empowerment of citizens to hold accountable those who plan, finance and deliver infrastructure and services.

CARES can also improve Management Information Systems, to assist decision makers and implementing agents with more robust systems for collecting and analysing information on the delivery of services, and to plan and enable efficient operations and maintenance programmes.

Whatever the system, CARES’ approach is to work from the ground up; from the users, operators and maintenance crews, to managers and governing entities; all with the aim of improving the individuals to improve the organisation’s performance.

CARES also understands the benefits and pitfalls of using Public Private Partnerships (PPP) for the delivery of water related infrastructure investments, and minimises risk by combining our understanding of the factors for success with our strong technical expertise in water and wastewater engineering.

CARES can provide the following services to governments, water utilities, municipalities and businesses:

  • Establishment of the key technical, behavioural and organisation factors affecting delivery
  • Development of policy and strategies for increased private sector participation
  • Auditing performance against key performance indicators
  • Identifying critical assets, performance, degradation, sustainability and public/political perception factors
  • Preparation of business plans and identification of investment drivers

CARES are able to offer comprehensive site investigation services, drawing on the combined expertise of our geotechnical, engineering and environmental staff, to deliver detailed investigations for any project, including groundwater investigations, foundations for dams, spillways and other hydraulic structures, scour assessments, onshore and offshore construction, contaminated land sampling and route optioneering investigations for canals, pipelines and sewers. CARES can undertake investigations in marine, riverine or terrestrial locations, encompassing a full range of services, including:

  • Desk studies and due diligence/liability appraisals to identify potential ground risks during early project stages
  • Management of the investigation procurement process, including tender evaluation
  • Site supervision and logging (environmental and geotechnical)
  • Factual and interpretative reporting
  • Test scheduling, sampling and laboratory analysis at accredited laboratories
  • Monitoring of water, soils, gas and dusts
  • Remedial options appraisal
  • Conceptual modelling and development of site-specific guideline geotechnical parameters
  • Geo-environmental assessment, monitoring and reporting
  • Advice on former military sites, including ordnance management.

CARES’ geotechnical and foundation engineering services are based on thorough understanding of ground conditions, enabling projects to be designed and completed safely and cost effectively. We determine the engineering soil parameters for the design of a range of foundation options, from residential pad footings to piled foundations for buildings and structures. Depending on the situation, CARES can specify different geophysical applications and geotechnical field tests to measure these parameters and formulate the best engineering solution, including ground penetrating radar, electrical resistivity and seismic survey, nuclear density, compaction control, dynamic cone penetration tests, plate bearing tests, soil permeability tests and light drop weight tests. CARES also utilises geotechnical instrumentation to monitor rock and soil slope stability and to give advance warning during deep excavation works.

Our site investigation services are tailored to our Clients’ specific requirements and the complexity of the project, and our structural and foundation designs take full account of ground conditions and uncertainties, to minimise risks to the contractor during construction, to ensure quality and durability of the completed works, and to limit any delays and cost overruns.

For sustainable construction in urban areas, CARES have experience in undertaking risk assessments associated with ground and groundwater contamination, buried tanks, utilities, obstructions, waste management and the interaction of new developments within the existing built environment. For contaminated sites we prepare remediation strategies as an integral part of the engineering designs. Issues of earthworks classification, waste minimisation and onsite treatment are all considered at design stage.

Condition Assessment & Rehabilitation Surveys

All infrastructure deteriorates due to changes in the environment and/or mechanical conditions, such as floods or earthquakes, and the management of existing assets is increasingly important, as owners and operators endeavour to maximise the benefits and lifespan of their investments, maintaining infrastructure in the best possible condition to be safe and reliable for its users. For this to be cost-effective, it is essential to have consistent and regularly updated information, on which to base informed management decisions. CARES can help clients handle these complex challenges through a comprehensive range of services, from condition assessment surveys to the non-destructive testing of materials and quality of construction, to analyse and determine the needs for rehabilitation and/or maintenance, and present in Management Information Systems (MIS) for real-time planning and monitoring.

CARES’ services apply to every phase of an asset’s life cycle and include the following:

  • Routine inspections, special inspections and measurements:
  • Defining the inventory of assets and data to be collected
  • Prioritising the critical assets for service performance
  • Formulating inspection schedules and methods, including the risks and Health & Safety issues
  • Monitoring and predicting asset performance, degradation and costs of O&M
  • Materials technology and testing
  • Monitoring and Management Information Systems
  • Life cycle costs and risk analysis
  • Rehabilitation programming, design and O&M supervision

CARES staff have significant experience of civil infrastructure, enabling them to identify issues before they become major problems. We perform measurements and condition surveys and plan any rehabilitation and maintenance schedules to suit. We utilise modern survey technologies, such as drone mounted cameras, and develop bespoke models to provide an analytical basis for deciding between options (e.g. operational changes, stabilisation/repairs, upgrades or complete or partial replacement). Using aerial photography and remote sensing, we can quickly screen long reaches of river banks for weaknesses, pipelines for leaks and irrigation canals for areas prone to overtopping, before failures occur.

CARES evaluate an asset’s condition through examinations, routine and special inspections and laboratory tests on construction materials. The assets identified as critical to system performance will be monitored more regularly for detailed information on the structure’s condition and rate of deterioration. Analysis then makes it possible to identify an optimal time to conduct major repairs.

CARES can also utilise non-destructive testing techniques to examine a structure, mechanical or electrical plant, without causing damage or an interruption in performance.

The ability to quickly share assets information with the clients’ management, field O&M staff and users of the infrastructure has many advantages:

  • Improved planning of Operations (e.g. Scheduling for savings and greater efficiency) & Maintenance (e.g. Scheduling closures during low periods of demand)
  • Prompt actions to avoid emergency situations and resolve issues quickly
  • More cost effective solutions, linking decision making to evidence based, analytical tools
  • Better cooperation among participating organisations and users
  • Enhanced understanding of the state of the infrastructure and modes of operation.

CARES can develop advanced MIS systems to monitor, analyse and report real-time O&M activities dynamically on the web, providing our clients, users and other stakeholders with a means to monitor and evaluate the status of services and any ongoing maintenance works, and plan their activities to suit. CARES has successfully provided such audit services over long-term contracts, giving us the ability to guarantee the functionality of the assets over time and help clients develop their O&M organisations, capabilities and procedures.

CARES are able to provide specialists to support investment and divestment needs, providing a range of services from screening assessments and design reviews to detailed due diligence and compliance assessments. CARES’ design evaluation services can cover the preliminary and/or final design, and aim to assess the technical quality of the selected design solution and assure safety and functionality for all stakeholders. The design drawings, calculations and specifications will be checked against the applicable codes, standards, legal requirements and purchase specifications, and risk assessed to evaluate the following:

  • Completeness, suitability and compliance of project documents
  • Reliability and timeliness of technical choices

The goals for a design evaluation include the following:

  • Assuring that the project can be awarded
  • Minimising the risks of variations due to incomplete design
  • Avoiding consequent delays and cost overruns
  • Minimising any claims from the contractors
  • Reliable scheduling for works completion and handover
  • Minimising contract management costs

CARES’ staff have experience of acting as Expert Witnesses for a range of inquiries, hearings and litigations, including the provision of services with regards to chemical spills, tank and pipeline leaks, which have resulted in impacts on surface and ground water bodies and the water-related environment. These services include the management of activities for mitigating impacts and the allocation of liabilities between
interested parties.
CARES believe in a client-focused approach built upon sound understanding of the environment in which our clients operate. Our staff will provide direct, independent, reliable and fact-based advice to enhance the clients’ understanding of the issues facing their projects and businesses, manage the risks and assure successful project outcomes.

We will evaluate the options with stakeholders to determine the best option, not only from the perspective of cost and water savings, but also the benefits during construction of local labour and available materials. Irrigation plays an important role in poverty reduction and, through careful design, this benefit can be targeted at vulnerable groups, such as female-headed households.

More important than the project infrastructure are the systems for Operation & Maintenance (O&M) and CARES staff have been at the forefront of the implementation of participatory management systems, based on detailed analysis of economics and regulatory policies, developing partnership approaches to scheme investments and preparing O&M manuals for sustainability. CARES work with stakeholders to ensure that infrastructure is developed and managed to suit the diverse range of interests and livelihood situations.

CARES provide a comprehensive range of irrigation services, covering all stages in the project cycle from identification through implementation to commissioning and future operation.

Water, Sanitation, Health and Hygiene (WASH)

Water supply, sanitation and hygiene (WASH) are basic services, crucial to human and economic development. However, for large numbers of Africa’s population, these services remain out of reach, with WASH infrastructure either not existing or, where it does exist, being poorly maintained and dysfunctional. Links between WASH and health systems are often overlooked, although, with the right policies in place, many countries have seen rapid increases in access to WASH, improved health outcomes and falling child mortality.

CARES work with Clients across Africa to improve sanitation and health conditions in both the rural and urban environment. Our specialists provide integrated and innovative technical and management solutions to enhance water safety, improve sanitation and change hygiene behaviour.

CARES addresses public health needs and improves access to safe water in vulnerable communities by helping to strengthen the capacity of our clients to manage the complex challenges involved in improving infrastructure and environmental health. In all our work, we can combine the social, environmental, economic and financial dimensions of each project to develop realistic, sustainable and affordable solutions.

CARES’ staff have many years of experience in WASH implementation and impact evaluation, as well as finance and economics, considering value for money and cost-benefit analysis of WASH interventions. CARES utilises a range of social and technical skills to implement WASH programmes:

  • Encouraging healthy behaviours and strengthening supply chains.
  • Improving the capacity of providers to deliver affordable, equitable and quality services to the poor.

The expertise and resources of both the public and private sectors are need to maximize the positive health impact in WASH programming:

  • We engage with the private sector to reach low-income households, as they access products and services every day through private providers and channels.
  • We work in close collaboration with the public sector, including governments, donors and policymakers, to coordinate efforts and to ensure that those who have less ability to pay are able to access products and services.

Our Clients and consumers are at the centre of our WASH solutions and services, utilising current and formative research to identify products and services that consumers want, as well as need.

Water User’s Associations, Participation and Training

Developments in water supply infrastructure and implementation of operational schedules can be severely disrupted by unrest in the communities of water users and other stakeholders, usually when there are groups of people who feel marginalised as a result of not been appropriately consulted during the project formulation or implementation phases. CARES understands that effective stakeholder engagement, consultation and disclosure planning, prior to and during implementation will help to minimise or completely avoid this disruption.

The aim of Water Users’ Associations is to establish a forum for beneficiaries to discuss and agree how water resources should be managed, utilising the infrastructure afforded to them by the project (Early formation of WUAs also enables the beneficiaries to be involved in the design and functionality of the infrastructure). A fully functional WUA requires the participation of all beneficiaries and support groups in a process that follows the established legal framework and ensures sustained interest by all stakeholders for the long-term Operation & Maintenance of the system. CARES adopts a ‘bottom-up’ approach, based on the basic principles and lessons learned from establishing grassroots organisations across Africa and Worldwide. In all cases, the key to success has been to ensure widespread awareness, consistency and stratified representation of the communities, through a democratic process of electing representatives. As for many participatory activities, particularly in rural and poor communities, incentives are often expected and the role of the facilitators is important to analyse suggestions and mutually agree incentives that are realistic and within the means of the group, but should aim to benefit the entire target group and consider the establishment of infrastructure, demonstrations, training and educational tours as suitable incentive, which have produced good results.

CARES’ experience shows that success can greatly depend on establishing a relationship of trust or partnership between the Client, host communities and other stakeholders. We facilitate this by designing and implementing stakeholder engagement, public consultation and disclosure plans in line with the requirements of international financiers and national regulators, and according to project and stakeholder needs and comfort levels. We are able to manage the entire engagement process, either as part of a wider programme or as a stand-alone service, including:

  • Formal channels with statutory government stakeholders
  • Private meetings with non-governmental organisations concerned about a project’s environmental and social impacts
  • Understanding, identification and mapping of all stakeholders
  • Strategies and plans for all stages of project and programme development and implementation - engagement, involvement, consultation, management and communication
  • Organising and managing the engagement process and organising meetings, workshops and focusgroups and wider public events and exhibitions
  • Public information disclosure campaigns in the media to reach the wider population
  • Facilitating technical and non-technical workshops, telephone interviews and focus groups, planning and design events and also chairing meetings and manning public exhibitions
  • Community meetings and participatory workshops with local communities, including special interest and vulnerable groups
  • Producing all supporting material including copywriting, media relations, graphics and multimedia design and print management
  • Social and market research
  • Ongoing reporting and integration of views in project and programme design

CARES use a range of both tried-and-tested and innovative qualitative and quantitative techniques to involve people from all identified target groups. We also develop communication material, visual and nonverbal, tailored to suit the particular audience, to reach the widest possible audience.

We are proud of our track record and reputation for effectively engaging with a range of relevant stakeholders on complex and sometimes controversial projects in a culturally appropriate and sensitive manner. Our professional communication and engagement consultants work hand-in-hand with our technical staff to ensure that we combine the highest standards of verbal and visual communication with in-depth technical knowledge. This allows us to establish trust and credibility, resolve issues, tackle negative perceptions and ensure everyone involved has a clear understanding and acceptance of the approach proposed and the resulting benefits.

CARES also has significant experience in providing training, tailor-made to give Clients clear appreciation of recent and proposed changes to legislative, standards and best practices in the various industries in which we operate, together with an effective understanding of how these will impact them and participate in developing frameworks for solutions to the challenges ahead. Training sessions are designed in consultation with the Client and stakeholders and geared to provide the exact range of skills required.

Surveys & Data Management

For improved understanding of water resources in Africa, leading to more sustainable development and improved environmental decision making, those responsible for water resource management require accurate and up-to-date information on the hydrological and environmental aspects of their natural water systems, to be collected, presented and analysed in formats that suit their needs. CARES provides its Clients with the capability for surveys and data collection utilising the very latest technologies, including landbased, manned and unmanned aerial vehicles, satellite imagery and remote sensing, offshore and nearshore platforms, and data management to suit the Client’s needs. Survey information and data can be delivered in a range of formats, including basic but precise data for standalone modelling (e.g. hydraulic models, asset management or pollution dispersion) or integrated surveys, modelling and bespoke Management Information Systems (MIS) for more complex water resource management projects (e.g. Irrigation scheduling and Operation & Maintenance).

Water Infrastructure Assessment & Engineering Design

CARES helps the owners and operators of water infrastructure assets to optimise performance, retain/add value for sustainability, and to benefit their customers and their financial position. Through detailed inspections and analytical assessments, and from a thorough understanding of our Clients’ businesses, CARES aims to develop strategic investment plans and maintenance schedules, so that water assets operate under cost-effective performance regimes and at optimum efficiency. CARES builds value for clients and helps advance the best practices of the water industry through innovation.

To achieve successful project delivery, CARES combines its knowledge and global experience of water resources (abstraction, treatment, pumping stations, pipelines, distribution networks, storage etc.) and wastewater (sewerage collection, transfer, pumping, rising mains, treatment and disposal etc.) with our skills and local expertise in infrastructure planning, design, rehabilitation and maintenance. With our experience in project management, partnering and supervising water infrastructure projects, we understand the complex issues involved in operating and maintaining water infrastructure and we use this knowledge to innovate and improve designs.

CARES provides advice and design solutions at all stages of the project cycle (from planning, feasibility and design to procurement, construction supervision and operation) to optimise water and wastewater networks. We utilise computer aided design, analytical methods and modelling packages (hydraulic, structural and financial) to assess and define the problems and to prioritise remedial measures and investment programmes. These integrated services are available to both public and private clients, since both face similar challenges to develop and sustain new and aging infrastructure, with limited funding and inexperienced staff resources.

CARES services in water infrastructure assessment and engineering design include the following:

  • Water utility infrastructure - CARES provide advice and engineering design to optimize water and wastewater networks (from planning, feasibility, design, and procurement to construction supervision)
  • Pipelines - CARES plans and designs for collection, distribution and transmissions pipelines for water supply, wastewater and treated effluents, for disposal or re-use. Pipeline routing is undertaken with careful consideration of the Client’s preferences, operating parameters, installation requirements and conditions along the route, including geology, hydrology, archaeology and existing infrastructure.
  • Pump stations - CARES’ services include studies and design for all civil, mechanical and electrical works, including commissioning assistance during start-up and operati
  • Treatment plants - CARES has experience with both clean water and wastewater treatment, including all conventional processes and new technologies, including UV disinfection.
  • Master-planning - CARES ensures that practical and cost-effective solutions are incorporated into water utilities master-plans, providing the necessary tools to support decision-making and future programmes. Our multidisciplinary approach integrates all relevant technical areas with demographic projections, regulatory policies and funding streams to optimise the benefits to all stakeholders, whilst minimising the risks to the Client.
Wastewater Design (Treatment, Re-Use & Outfalls)

CARES has extensive experience in all aspects of wastewater and sludge treatment, encompassing all sizes of treatment plant, innovative and conventional technologies (preliminary treatment, primary treatment, secondary treatment, tertiary treatment, disinfection, and solids handling), contemporary micro-scale and constructed wetlands technologies, and physical and biological treatment processes (UV disinfection and Biologically Activated Flooded Filtration BAFF).


We can manage all aspects of wastewater treatment, from initial optimisation of processes to minimising and re-using the effluents and solids generated. Our expertise covers both the development of new sites, and optimising and extending the life of existing sites, including:

  • High-level scope definition
  • Feasibility studies
  • Outline and detailed design
  • Operating and capital cost evaluation
  • Tender/contract preparation and analysis
  • Contract supervision
  • Site supervision
  • Commissioning support
  • Design evaluation
  • Due diligence
  • Process optimisation
  • Process operation

Environmental issues such as odour minimisation, containment, abatement, noise and visual aspects of treatment plant can be incorporated, where appropriate, together with more advanced treatment techniques and innovative design approaches. Our aim is to provide solutions which are appropriate to our Clients’ needs. We consider projects on an individual basis to provide solutions that are consistent with discharge requirements and determine the most appropriate and cost-effective solution. Our approach to wastewater problems puts emphasis on understanding the site specific mechanisms which affect process performance, before determining the most appropriate solution.

Operation & Maintenance (O&M) and Tariff Analysis

Operation & Maintenance requirements and costs should be established at the outset of a project to ensure that water-related infrastructure is designed for sustainable operation and the institutions are established for adequate revenue generation. CARES combine engineering and management expertise to provide a total solution for O&M, taking a whole-life approach to integrate assets management into the project objectives and maximise the benefits to our clients and service users.

CARES’ whole life approach focusses on value and operational performance, as well as a very practical understanding of the service users’ requirements. We provide advice relating to all aspects of the design, O&M, management and funding of waterrelated services. As such, technical due diligence services are a useful first step to verify the status of water-related infrastructure; to evaluate the technical adequacy of the original design concept and the functional conformity with required construction specifications and performance standards, as well as compliance with current legislation. These services would be undertaken in two stages; a design review, to analyse all technical documents and design data, and a physical inspection, to assess the status of assets with regards to levels of maintenance and performance.

Efficiency is at the core of CARES’ O&M services to clients and we focus efforts on the systems and components that we know have the greatest potential for savings. CARES offer the following O&M services to assist clients improve service performance and lower costs, enhance communications and planning, develop partnering in the supply chain and achieve statutory compliance:

  • Strategic reviews
  • Technical advice and design reviews
  • Contract procurement and monitoring
  • Performance and service management
  • Operational and statutory audits
  • Due diligence of service providers
  • Lifecycle due diligence
  • Assets management
  • Service standards design and specification
  • Whole-life cost engineering
  • Tariff setting

Efficient O&M systems require an effective inspection schedule and MIS system to share relevant information, with tools and resources to identify, schedule and implement the necessary actions. CARES can support clients to set up alternative O&M delivery models, outsourcing many of these services to private contractors, including workshops to explain O&M services, typical models and the benefits and potential drawbacks of outsourcing. O&M costs over the life of an asset far outweigh the initial construction cost, and can be as much as 80% of the whole life costs for an asset’s service life. CARES can assist clients at the design stage to optimise the specification of components and construction materials by minimising the capital and recurrent costs (e.g. A more expensive pump may have a lower whole-life cost because it is more efficient and requires fewer spare parts), and during the operations phase we can set the base life cycle budget and determine required income levels for sustainability. Further analysis of this base case can take account of government subsidies and other discounts, and determine the appropriate tariff levels to be charged to service users. Through this detailed financial analysis and technical understanding of the infrastructure characteristics, CARES can identify, design and implement life cycle cost savings for the project, demonstrating to the client how assets compare against other similar installations, improving efficiencies in service provision and fee collection, and demonstrating value for money to service users.

CARES aim is to work closely with our clients to understand their business needs, appreciate how services are currently delivered and if they meet user and regulatory requirements. Our advice is therefore specifically tailored to create bespoke solutions to ensure that services match or exceed the client’s objectives, including protecting their investment assets in the long term, and provide best value to the users/beneficiaries, by illuminating any potential opportunities to reduce expenditure and increase benefits through alternative delivery models.

CARES staff have a broad range of experience covering engineering and management services in both the public and private sectors, and can draw on support from a large, global, multi-sector network of consultants.

Catchment Management, Masterplanning & Programming

CARES can provide integrated catchment management services at all locations within the managed water cycle, from source to sea, enabling the supplies to water resource users to be optimised and environmental objectives to be achieved. CARES’ support to river basin managers and other stakeholders will enable them to find sustainable and cost effective solutions to water quality problems, abstractions planning and licencing issues, and to achieve compliance with environmental regulations.

CARES experience includes water quality modelling and monitoring in rivers, lakes and coastal waters, evidence based assessment of the
effectiveness of policies, development of management solutions and the provision of expert advice on risks to human health and the environment.

CARES applies an Integrated Water Resource Management (IWRM) approach, ensuring that:

  • All water users are considered as key participants, to establish more efficient management and use of water resources and improve equitable access for all water users.
  • All interventions are designed and implemented to mitigate and minimise environmental impacts, leading to sustainable access to water for all users into the future.
  • Improvements in access to water for the current generation are made without affecting the ability of future generations to meet their water needs.

CARES offers a wide range of land-use planning and urban design skills, recognising that master-planning underpins the majority of development in the modern world, and our services are tailored to a variety of projects and clients. In the water resources sector we can draw upon a large number of qualified and experienced planners to work closely with other specialists, including environmental scientists, water
supply and wastewater engineers, transport planners and sustainability experts, to manage projects from inception to completion.
CARES’ master-planning and urban design expertise covers a wide range of services:

  • Master-plan layouts and development phasing
  • Land-use classification (requirements for open space, infrastructure, public access, landscape etc.)
  • Servicing, highway or environmental considerations
  • Statutory planning advice (planning appraisals, applications and consents)
  • Public inquiry and expert witness
  • Site planning and development potential reviews
  • Public consultation (planning workshops, presentations, awareness campaigns and media relations)
  • Project management to co-ordinate specialists and ensure delivery on time and on budget
  • Economic and social development (market analysis)

In all sectors, but particularly water resources, limited funding is under significant pressure, therefore the programming of assets investment, refurbishment and replacement becomes critical. CARES can assist clients to optimise the benefits and provide evidence based decisions through the following services:

  • Strategic review - CARES understand the business drivers and provide strategic planning advice.
  • Investment programme optimisation - CARES model investment alternatives to determine the optimum performance at least whole-life cost.
  • Asset management plans - CARES develop optimised plans to maintain a steady state condition.
  • Reliability modelling - CARES predict the impact of failures and propose mitigation measures.
  • Deterioration modelling - CARES determine the functional design life of assets to fully optimise asset management plans.
  • Lifecycle cost modelling - CARES cost the main phases of an asset’s whole life, from conception, through construction to operation and decommissioning.
  • Carbon reduction - CARES considers an asset’s future performance to take account of CO2 trading and tax strategies to save on project whole-life costs.
Flood Risk Assessment & Flood Protection Schemes

Rivers have a critical role in all many of our lives, since they provide water and food (e.g. irrigated agriculture and fishing), but occasionally they can be destructive, with floods damaging land and properties, and endangering lives. CARES have experience understanding these issues and providing sustainable solutions. CARES water resources experts have modelled, designed and delivered flood management schemes around the world, utilising state-of-the-art modelling and design techniques to deliver effective, economic and sustainable schemes in both urban and rural areas.

Hydrodynamic modelling speeds up the design and planning process and provides greater detail and accuracy than existing flood risk mapping. CARES utilise 1D and 2D hydrodynamic models of watercourses and their associated floodplains (e.g. MIKE FLOOD, ISIS / Flood Modeller, TUFLOW and HEC-RAS) to understand the flood hydrology and assess the flood risks. Modelling also enables study of other characteristics, including:

  • Flood depths and velocities
  • Scour/Erosion
  • Sediment transportation and morphology
  • Reservoir inundation
  • Water quality
  • Dam breach assessment
  • Risks to essential infrastructure (e.g. power utilities)
  • Coastal modelling services

The link between weather and floods is crucial to understand, to ensure that people are prepared and safe from the dangers of flooding. CARES have been involved in weather forecasting projects with the MetOffice to improve forecasting on small ungauged and ‘data-poor’ catchments in Africa.

CARES’ flood risk and flood protection services also include the following:

  • Master-planning
  • Structural condition assessment
  • Manhole survey and investigation
  • Topographic survey
  • Detailed engineering design
  • Flood damage assessment
  • Catchment management
  • Construction supervision
  • Groundwater monitoring, licensing and management
  • Integrated Water Resources Management (planning and management for all users)
  • Climate projections
  • Hydrological assessment
  • Economic assessment
  • Environmental water management
  • Policy advice and stakeholder engagement
  • Flood forecasting and warning

CARES incorporate innovative methods to alleviate flood damage and carefully consider the environmental, sociological and sustainability impacts of each flood management scheme. Our integrated approach is based on a detailed understanding of the consequences of actions taken within a catchment and the impacts of population growth, climate change and government policies. Only by considering the resources, impacts and risks as an integrated management package will a sustainable solution be possible.

Contract Documentation & Procurement Management

Project outcomes can be greatly improved by timely interventions by specialists with significant contract management experience and knowledge of local conditions. CARES provide contract advisory services including contractual advice, administration, procurement management, project cost recovery, claims adjudication, arbitration and dispute resolution, and expert witness to get the best results possible. Based on its experience in its core sectors of Maritime, Infrastructure, Oil & Gas and Mining, CARES provides Clients with an independent, reliable, fact-based consultancy service to assist understand the issues facing your projects and contracts. CARES services are client focused and our staff have an in-depth understanding of local operating environments to deal with, manage and resolve contract issues quickly.

CARES provides strategic solutions based on a shared assessment of the risks and provides key resources at the appropriate stage of implementation to ensure timely and cost-effective decision making for minimal risk and optimal reward. We believe that through early involvement we have the greatest impact on the project outcomes and our staff and specialised consultants are highly experienced and able to visit sites and Client offices across Africa. CARES services in contracts and procurement management include the following:

  • Procurement advice
  • Document drafting and review
  • Oversight reviews, advice and audit
  • Training
  • Strategic reviews and advice
  • Claim and dispute management and resolution
  • Risk management
  • Mediation, adjudication and arbitration
  • Expert witness

Poor contract documentation, administration and management often leads to poor delivery and contractor performance, and ultimately to failed projects. However, CARES follows project risk management procedures, with robust identification, assessment and control of all sources of project uncertainty from inception through to delivery and operation, to optimise opportunities and increase resilience to external factors. CARES is therefore able to control costs and achieve schedules, increasing the Clients’ confidence and ability to steer the project towards a successful outcome.

CARES approach can be employed to satisfy other compliance requirements, such as corporate governance and social responsibility, ensuring that the Clients’ policies, internal controls and audit schedule are fully integrated into the project. Integrating procedures, rather than externalising, ensures transparency and accountability and puts the Client firmly in the driving seat to control cost, specify quality and set schedules.

We also employ risk management techniques to identify and assess the potential risks during Operation & Maintenance of an asset to ensure that changes can be incorporated during detailed design. CARES can also provide asset management advice on service and performance contracts, institutional capacity and training, sources of funding and the business case for development.
