The National Water and Sewerage Corporation (NWSC) says it has resumed work on the new water treatment plant in Katosi, Mukono district and it’s on the last leg.

In a Tuesday statement, the Corporation revealed that the plant, which will produce 240 million liters of water per day and serve over 7.5 million people – is at 95%.

NWSC Director Engineering Services Eng Alex Gisagara they are now testing the plant’s systems, looking at electrical control units, water pumps, pipelines, among others.

Eng Denis Taremwa, who manages the project – says the first drop of water is expected to reach the new Nsumba water reservoirs by the end of April.

The Deputy Managing Director Technical Services Eng Johnson Amayo says NWSC is moving away from the traditional treatment of water by sedimentation to the use of dissolved air floatation, in order to deal with the problem of increasing algae on Lake Victoria.

"Upon completion, the Katosi plant will be the first and biggest plant in East and Central Africa using the AquaDAF and AquaZur technologies," he said.

The state-of-the-art plant shall incorporate water recycling and sludge thickening to minimise plant losses and promote environmental conservation.

Project Scope

• A 500m offshore abstraction pipeline into Lake Victoria.

• A scada system that will be integrated with the existing NWSC installations

• A modern laboratory to enhance water quality monitoring and management

• A mechanical workshop

•A compact wastewater treatment plant

•A solid-waste handling and incineration facility

• A modern staff housing estate with modern amenities and recreation facilities

From the plant, water shall be pumped to the new Nsumba reservoirs (40million litres capacity) through a 9.5km bulk DN1400mm pipeline.

•The water shall thereafter gravitate to Kampala via Mukono – Seeta – Sonde – Namugongo, through a 55km DN1400mm bulk pipeline.

•The Project also entails construction of a 15million litre reservoir in Sonde and booster station in Namugongo.

The project also has a component to supply water to Katosi, Lugazi town and the surrounding areas.
