Technical support to reduce water losses

This project is part of the Lusaka Water Supply, Sanitation and Drainage Project (LWSSDP) funded by the U.S. government through the Millennium Challenge Corporation, which aims to improve the living conditions of the population of Zambia’s capital. The project’s objective is to assist Lusaka Water and Sewerage Company (LWSC) to reduce water losses from an estimated 48% to a target value of 25%. Efforts are focused on defi ning strategic action plans and deploying tools and methods with continuous transfer of skills and knowledge to local teams.




  1. Supervision of works to rehabilitate drinking water systems (110 km).
  2. Evaluation of physical losses and implementation of leakage reduction:
    A redefinition of the city’s existing water supply zoning;
    A measurement campaign;
    The calculation of levels of losses;
    The localization of leaks;
    Detailed design for the rehabilitation of the 65 km of pipelines identifi ed as having the most leaks.
  3. ​Assessment and reduction of commercial losses: complete update of the customer database with modifi cations to the land registry, door-to-door data collection using electronic forms, reconciliation of the field and existing databases, identification of metering problems, billing and fraud, and definition of commercial loss reduction and regularization plans.

    Seureca is also in charge of transverse activities to ensure that these efforts are sustainable: updating all the processes and procedures related to managing unaccounted water, provision of equipment to locate leaks, and employee vocational training.
