Katosi drinking water treatment production plant (Uganda)

In 2018, the National Water and Sewage Corporation (NWSC] as Ugandan public authority in charge of water and sanitation management INWSC), awarded SUEZ and its partner, Sogea Satom, the contract for the design and construction of the Katosi drinking water production plant, with a capacity of 160,000 m³/day with the aim of supplying more than 7.5 million people by 2040 in Kampala, Wakiso and Mukono.

project highlights

This project is part of a program aimed at rehabilitating and extending the drinking water distribution network in Kampala, in response to significant population growth.
The goal is also to support the Ggaba drinking water treatment plant, south of Kampala, the only one in the capital previously.
For this new plant, the treatment differs from the conventional treatment implemented on the existing Ghaba plant, in order to deal with the problem of algae proliferation on Lake Victoria.
The construction takes into account significant seismic constraints in the region.

water treatment line

This plant includes:

• • An offshore water intake located 500 meters inside Lake Victoria was designed to improve the quality of raw water.
  • 4 AquaDAF®, a rapid dissolved air flotation process
  • 12 Aquazur® V sand filters
  • A final disinfection
  • A sludge bed drying.

The treated water is then sent nearly 10 km from the site to two 10,000 m³ reservoirs each.
In total, this project required the construction of 55 km of pipelines.
