National Water Security & Sanitation Program

A program addressing drinking water treatment and distribution, leak reduction, wastewater treatment and flood resilience. The program is at NBP-2 on the NBP readiness ladder and is recorded at concept confidence. Scope, cost and structure remain subject to the studies listed below.

Distribution losses reduce the volume of treated water that reaches consumers, so treatment capacity increases deliver less benefit than expected. Wastewater and stormwater systems are separately constrained.

Improve reliable access to safe water and reduce the public health and economic costs of inadequate sanitation and drainage.

Assess leak reduction and distribution improvement alongside treatment capacity, since the two are interdependent, together with wastewater treatment and drainage in the highest-risk urban catchments.

• Water treatment capacity
• Distribution network improvement
• Leak detection and reduction
• Reservoir capacity
• Wastewater treatment
• Stormwater and drainage
• Smart metering

Location: Multi-country, Africa

Urban and rural households, health facilities, industrial users, and municipalities managing flood risk.

• Technical scope to be established through pre-feasibility study
• Design standards to follow applicable national and international codes
• Environmental and social screening prior to design finalisation

• Electricity supply
• Network condition data
• Institutional capacity
• Land for treatment works
• Skills in network operation

Reducing distribution losses is generally the lowest-cost source of additional supply, which is why it is assessed before new treatment capacity.

Delivery and ownership structure to be determined at commercial structuring (NBP-6). Options include public delivery, partnership structures and concession models, assessed against value for money and risk allocation.

To be determined. Suitable capital categories will be assessed at NBP-6 and NBP-7 against the project’s risk profile and revenue characteristics.

Revenue and sustainability model under development. Where user charges are not viable, availability-based or budget-funded models will be assessed.

Classification: To be assigned following environmental and social screening.

Environmental assessment will be completed to the standard required by national regulation and applicable lender policy before any commitment is sought.

Social assessment will address land, livelihoods, resettlement risk, community consultation and equitable access to the resulting service.
