Fixing Kisumu Sewerage

Fixing Kisumu Sewerage

Kisumu County through the Ministry of Interior and Coordination of National Government plans to construct a KShs 40 million decentralized Sewerage treatment facility as it seeks to improve water and sanitation services. The Ministry of Interior is set to release a grant for the development for a sewage treatment plant for Kibos Prison and its environs.

The move is expected to ease the burden on the two existing amenities, which manage 16 per cent of the households connected to the public sewerage. Speaking during a guided tour of Kibos Prison, Chief Administrative Secretary Ministry of Interior and Coordination of National Government Madam Winnie Guchu accompanied by Commissioner General of Prisons Mr. Wycliffe O. Ogallo, CBS, said the project will be funded by Water Sector Trust Fund in Collaboration with the Kisumu Water Supply and Sanitation Company Limited who will assist in management of the plant on Completion.

The prison that is currently operating a conventional treatment plant has been embroiled in an environmental war with the community who accused them of emptying raw sewer into a local stream.  Currently with the increased number of offenders, the facility cannot accommodate the increasing number of inmates.

“The government has stepped in to address any environmental challenges posed by the outdated facilities at the prison. Water Sector Trust Fund is able to source for funds from different development partners, so the water treatment plant is a decentralized facility.”

Construction of the sewage treatment plant is set to commence this October. Final designs are near completion and the engineers are set to make final arrangements to have a procurement call placed in the local dallies. The plant will convey, treat, dispose or reuse the waste water and make briquettes. It will also improve on sanitation through waste water management in Kisumu Command and curb pollution to the environment.

The ministry estimates that 10,000 people will benefit from the new facility. This includes Kibos Prison, prison staff and the neighboring community. According to the Commissioner General of Prison Service Wycliffe Ogallo, the prisons will remain with a good chunk of land for other purposes. The current facility was developed to cater for 2,000 people but the pollution had increased significantly over time thus stretching the facility.

“We have a population of about 7,000 including inmates and the staff working here and another 3,000 people in the community that is neighboring the correctional facility.”

The treatment plant will allow exhauster trucks to dispose of their contents from the field for treatment and will require a small piece of land as opposed to the current system which has seven huge ponds taking up a huge parcel of land.


With a population of about 600,000 people, Lake Victoria South Water Services Board had raised concerns that lack of a treatment plant could be a disaster in the waiting as most residents deposit raw sewage in Lake Victoria. Completed works on sewerage and wastewater include Nyalenda waste stabilization ponds (29,000m3 per day), Kisat Wastewater Treatment Plant (11,000m3 per day) and pumping stations rehabilitation.

On another front, the government, KIWASCO and Lake Victoria South Water Services Board have announced improvement components of a 39 Million Euros project funded by The Agence Française de Développement (AFD) Group. The developments include:

  • Rehabilitation and extension of the sanitation systems (Nyalenda Ponds, sewerage network);
  • Construction of a new wastewater treatment plant at Otonglo;
  • Capacity building of the Lake Victoria South Water Services Board and Kisumu Water and Sewerage Company (KIWASCO), the utility responsible for managing water and sanitation services;
  • Extension of the water network in informal settlements and the urban centres of Ahero, Maseno and Darajambili;
  • Setting up a system for monitoring the quality of Lake Victoria.

The aim is to increase the capacity of the treatment facility and sewage system at Kibos Prison and more so to make it modern. The Kisat plant has a capacity of treating 5,000 to 6,000 cubic meters of waste per day while the Nyalenda Ponds and Pumping Station and handles the bulk of discharge generated. Once the plant is completed, it will be handed over to Kisumu Water and Sewerage Company (KIWASCO) for maintenance and operations.
