SiBo Sanitation Works

Lake Victoria, Kenya

The customer, the towns of Siaya & Bondo Water & Sanitation Company Limited (SiBo), required a water turbine and pump solution that would deliver clean water to their local population utilising the energy available within the existing local river. The project to upgrade and expand the existing SiBo WTW was financed by the African Development Bank and Government of Kenya to deliver a clean safe water supply to over 100,000 present population.

Gilkes solution proposed utilising 5 Francis turbines directly driving 5 KSB Multitec multi-stage water pumps.

The river off-take just above a waterfall provides both the raw water to power the turbines and the raw water supply to the water treatment works, which subsequently supply clean water to the pumps.  The water pumps are gravity fed from the water treatment works, pumping the clean water over 4 kilometres to two reservoir tanks.

Each turbine & pump unit was assembled at Gilkes manufacturing facility in the UK and transported to site fully assembled, just requiring anchoring and plumbing in once on site. The units were skid mounted, meaning the pump and turbine could be aligned in-house before being transported to site, resulting in less on site installation & commissioning time and providing a solution to the lack of on-site tooling.

Gilkes are very proud to have been involved in such a unique project. With a Chinese lead contractor, an Indian civil engineering consultant, a local Kenyan workforce and the customers own engineers, this was a truly multi-national contract. Working in close collaboration with all parties ensured the success of the SiBo project.
