Water and Sanitation: The Business of Essential Services in Africa

Access to safe water and adequate sanitation is among the most fundamental dimensions of human wellbeing and public health, and one of the most significant remaining development challenges across the African continent. Waterborne diseases associated with unsafe water and poor sanitation remain major causes of preventable illness and death, particularly among children. Economic productivity is affected when workers and schoolchildren spend significant time collecting water from distant sources. And the costs of inadequate sanitation — in healthcare expenditure, lost productivity, and environmental degradation — are borne disproportionately by the poorest communities. The structure and performance of the businesses, utilities, and systems through which water and sanitation services are delivered therefore has profound implications for both development outcomes and economic activity.

Water Utility Structure

Piped water supply — the delivery of treated water through distribution networks to households and businesses — is provided across most African cities primarily by urban water utilities, which are in most countries publicly owned entities operating under mandate from national or municipal governments. These utilities range in scale and operational quality from well-managed, financially viable entities achieving good coverage and service quality to severely financially constrained operations struggling with aging infrastructure, high non-revenue water, and inadequate tariff recovery. Non-revenue water — the portion of water that enters the distribution system but is lost before generating revenue, through leakage, illegal connections, and metering inaccuracies — is a major operational challenge, with very high rates in some utilities representing both significant financial loss and a barrier to expanding service coverage with available water resources.

Tariff Policy and Financial Sustainability

A persistent challenge for African water utilities is the tension between the social imperative to keep water affordable for poor households and the financial requirement to collect sufficient revenue to cover operating costs, service debt, and fund infrastructure maintenance and expansion. Many African water utilities operate under tariff structures that deliberately keep basic household tariff levels below full cost recovery, with the shortfall subsidised by government transfers, cross-subsidies from commercial customers, or simply deferred maintenance that depletes infrastructure over time without adequate reinvestment. Designing tariff structures that are affordable for low-income households while providing sufficient revenue for sustainable utility operation — potentially through increasing block tariffs that provide a basic consumption allowance at low rates while charging higher rates for higher consumption — is a complex political economy challenge that requires sustained policy attention rather than purely technical solutions.

Rural Water Supply

Outside urban areas, piped water supply is far less common, and rural water access typically depends on boreholes equipped with hand pumps or motorised pumps, protected springs, rainwater harvesting, or in some communities still on unprotected surface water sources. The coverage and reliability of rural water infrastructure varies enormously across the continent, with some areas having functional borehole infrastructure maintained through community management models, and others having infrastructure that was installed but has since broken down without adequate maintenance due to lack of spare parts, technical skills, or community organisation to manage and fund ongoing maintenance. Sustaining rural water infrastructure over its useful life is as important as initial installation, and models that build genuine community capacity and financial mechanisms for maintenance — rather than relying entirely on external repair support — are important for long-term rural water access sustainability.

Sanitation Services

Access to adequate sanitation — facilities that safely contain and manage human waste — is less developed than water access across much of Africa, with open defecation remaining common in some rural areas and many urban informal settlements relying on shared or inadequate toilet facilities rather than individual household connections to sewerage systems. The health consequences of poor sanitation — including diarrhoeal disease, soil-transmitted helminth infection, and environmental contamination affecting water sources — make improved sanitation one of the most cost-effective public health investments available. Sanitation improvement strategies have evolved from a focus primarily on infrastructure provision toward approaches that integrate behaviour change communication — addressing social norms and practices around open defecation — with infrastructure supply, recognising that building toilet facilities does not automatically lead to their use if social practices and attitudes do not simultaneously change.

Private Sector Participation

Private sector participation in water and sanitation services takes multiple forms, from full privatisation of utility operations to management contracts, service contracts for specific functions such as meter reading or non-revenue water reduction, and the role of small private providers serving areas not covered by formal utility networks. The track record of full private operation of urban water utilities in Africa has been mixed, with some concession arrangements achieving service improvements and efficiency gains while others have generated controversy around tariff increases, access for poor households, and the renegotiation of concession terms under political pressure. Small private water vendors — typically selling water from tanker trucks or at kiosks — play a significant role in serving households without direct utility connections, often at prices much higher per litre than utility-supplied water, underscoring the economic cost of access gaps in formal utility coverage.

Climate Resilience and Water Security

Water security — reliable access to adequate quantities of safe water for household, agricultural, and industrial use — is increasingly affected by climate variability and change across many African regions. Droughts that reduce surface water availability, flooding that contaminates water sources, and shifting rainfall seasonality that affects groundwater recharge and surface water flow all have direct implications for water supply reliability. Building climate-resilient water infrastructure — diversifying water sources, expanding storage capacity, improving demand management through efficiency measures — is an increasingly important dimension of water sector planning as climate projections indicate more severe hydrological variability in many African regions over coming decades.

Looking Ahead

Progress toward universal access to safe water and adequate sanitation across Africa requires simultaneous attention to infrastructure investment, utility performance improvement, tariff policy reform, rural service sustainability, and the behaviour change dimensions of sanitation improvement. Development finance institutions, governments, and the private sector all have important roles to play, and the most successful approaches have generally combined sustained financial investment with genuine institutional reform that improves the governance and operational performance of the service delivery organisations responsible for translating that investment into reliable services for all households.
