Sustainable Urban Sanitation Services in Lusaka
Reference: International Finance Corporation (World Bank)
How do you create sustainable wastewater solutions in major cities in developing countries? Viegand Maagøe is working to deliver basic services at an affordable cost in Zambia’s capital Lusaka.
How we completed the assignment
Lusaka is the capital of Zambia and one of the fastest growing cities in Africa. There is a shortage of sewers and many cities depend on simple latrines and septic tanks. If they are not emptied, the wastewater seeps into the groundwater creating recurrent problems with cholera during monsoon seasons.
Viegand Maagøe has together with the World Bank advised the commercial utility company Lusaka Water and Sewerage Company (LWSC) on results-based contracts for construction of better individual sanitation and a franchise model for emptying individual sanitation facilities at an affordable price.
We have also developed a modelling tool and finance strategy for improved sanitation in Lusaka in 2030. This supports the continued dialogue between the water utility, law makers, city council and international development partners about the long-term sustainability of the sanitation sector.
The result is a finance strategy that balances investment needs, demands for commercial operation and the population’s limited finances.

Contract period: 2018 - 2019 (Viegand Maagøe)
Viegand Maagøe has completed:
- Resultsbased construction contracts for better individual sanitation
- Franchise model and performance-based multi-annual service contracts for emptying of facilities
- Financial modelling of contract economy and need for subsidies
- Establishing service targets, KPIs, payment model and verification process
- Workshops with potential suppliers and operators to test the market
- Procurement documents and assistance to the authority during procurement
- General cost model for sanitation in cities consistent with RAB principles
- Estimate of costs and profits related to better sanitation in Lusaka until 2030
- Assessment of possible ways to cover the distance between sector revenues and costs.
Results
The project will provide 90.000 citizens in informal peri-urban areas in Lusaka with access to new improved individual sanitation solutions and regular emptying of their facilities at an affordable price.
It also lowers the risk of cholera during the monsoon seasons for all citizens in the area.
