The Millennium Challenge Corporation (MCC) and the Government of Zambia signed a Compact, worth about USD 355 million, that focuses on the improvement of water supply and sanitation infrastructure in the capital city of Lusaka. The purpose of the Compact was to enable access to clean and safe water supply and adequate sanitation services for the residents of Lusaka. The compact ended in November 2018, but works still continued and services from Consultant’s were required to complete the project. The newly created Millennium Project Completion Agency - Zambia (MPCAZ), financed by Government of Zambia, contracted various parties to continue providing services to complete the outstanding works under various contract packages.

The project dealt with the rehabilitation of Iolanda Water Treatment Plant and transmission mains, expansion of the primary network grid (DN900 to 1200 mm, length 22 km), NRW reduction programme in selected areas, expansion of secondary distribution networks (Central Branch and Chelston Branch) of approx. 220 km secondary pipes, rehabilitation of Chelston sewer pumping station, sewer expansion of Mtendere (approx. 82 km of sewer pipes, DN 150 to 600 mm), Kaunda Square interceptor upgrading, Kaunda Square ponds rehabilitation and expansion. Additional contract assignments were included as contract addendum, such as "Identify Commercial Non-Revenue Water (NRW) Losses" and "Design modification for Kafue River Intake Pumps at Iolanda Treatment Plant".
