In rapidly urbanizing Lusaka, infrastructure and services are lagging far behind growing new demand. This requires innovation and exploring new approaches from the Lusaka Water and Sewerage Company (LWSC) and its stakeholders, such as an innovative Condominial Sewerage pilot launched in the Kalingalinga area. Condominial sewerage is an application of simplified sewerage coupled with targeted community engagement and ongoing interactions between users and agencies during planning and implementation. Funded by the Zambian Government and supported by World Bank technical assistance , it aimed at learning lessons on citizen-focused sanitation marketing and hygiene promotion to inform peri-urban services across the city. The project’s achievements and challenges both offer important lessons on citizen engagement.
