Dunga wastewater treatment plant, which is located in Kisumu County, Western Kenya, is set for refurbishment under the Lake Victoria Water and Sanitation Programme (LVWATSAN) that is implemented by the Lake Victoria South Water Works Development Agency (LVSWWDA).
The planned works concern two pumping stations built back in 1958 and 1985 with a capacity of 10,000 m³ and 14,000 m³ of water per day respectively. According to a report submitted to the National Environment Management Authority (NEMA) for approval, LVSWWDA notes that the pumps at the aforementioned pumping stations operate with very low efficiency and they, therefore, need major rehabilitation works.
The agency proposed the installation of pumps and accessories and installation of power supply, including transformer upgrading for lighting. As part of the project, the capacity of two more stations, built between 2007 and 2011 will also be increased from 21,000m3 to 46,080m3 per day.

Kisumu’s main source of water supply will also undergo improvements on the collection and distribution chambers, sedimentation tanks, filter units, and treated water collection channels.
Funding for the Dunga wastewater treatment plant rehabilitation project
The entire project is expected to cost approximately US$ 8.2M. Out of the total amount, US$ 717,000 has been budgeted for the repair of the Dunga raw water intake works, US$ 3.5M for the sludge treatment works, and US$ 3M for electromechanical and small civil works, among others.
The funds will be sourced from the US$ 68.1M earmarked jointly by the French Development Agency (AFD), the European Investment Bank (EIB), the European Union (EU), and the Kenyan government for the implementation of the LVWATSAN program.
As part of the latter two other treatment plants, as well as wastewater stabilization ponds in Kisat and Nyalenda will be rehabilitated, and a new wastewater treatment facility with a capacity of 4,000 m3 per day will be built near the Otonglo area.
The entire LVWATSAN program is expected to end in 2025 upon which it will provide safe drinking water and sanitation facilities for 350,000 people in Kisumu County.
