Tanzania, Mwanza

What

Sewer Connection Upgrade

High priority justification

The capacity of the Ilemela wastewater treatment plant is currently underutilized. The plant can be operated at its full capacity by expanding the existing sewerage system with infill sewers, and by connecting some 1600 households.

Context

The project area is Mwanza City, the second largest city in Tanzania. Mwanza is located in the north of Tanzania, directly along the shore of Lake Victoria.

 

The City of Mwanza wants to reduce the pollution load of Mwanza town currently discharged into the Lake Victoria. The rocky soils in Mwanza do not favour affordable on-site sanitation systems. The hilly topography favours the ‘illegal’ emptying of full pits during the rains. Therefore, Mwanza has chosen off-site sanitation as the preferred wastewater management system in the future, expecting the town will grow to 1.9 million inhabitants in 2035.

A Wastewater and Sanitation Master Plan has been prepared for the expansion of sewerage. The Master Plan foresees three Wastewater Treatment Plants (WWTPs) in Mwanza: one existing plant (Ilemela) and two new plants. The Ilemela WWTP is currently not utilized up to its design capacity due to the lack of sewer connections.

 

To enhance the collection of wastewater, and to improve sanitary conditions, the HPI aims at constructing 14.4 km infill sewers to collect and convey wastewater generated in 4 urban areas to the existing Ilemela WWTP.  To achieve the full load of the plant, the construction of 1,600 sewer connections is targeted. A sewer connecting strategy will be developed.

The National Project Executing Agency is the Water Supply and Sanitation Authority Mwanza (MWAUWASA)

 

Status

The Final updated Feasibility Study is completed, and all comments were addressed. A detailed topographical survey will be conducted in the detailed design phase. The final FS has been adjusted based on existing designs of MWAUWASA, with more detailed maps and hydraulic calculations. LVBC and the Project Executing Agency (MWAUWASA) approved the FS. No Objection from KfW has been obtained, meaning the Project and Funding Agreement (PFA) can be signed. This will clear the way for detailed design, tendering of construction works and the start of construction in 2022.
