WASAC awards Culligan contract to design, install WTP in Rwanda, Africa
The Water and Sanitation Corporation in Rwanda, Africa, has awarded a contract to Culligan International to design and install a water treatment plant that will provide drinking water to Kigali, that country's capital city.
ROSEMONT, IL, Feb. 23, 2015 -- The Water and Sanitation Corporation Ltd. (WASAC) in Rwanda, Africa, has awarded a contract to Culligan® International, a global innovator of advanced water treatment solutions, to design and install a water treatment plant that will provide drinking water to Kigali, that country's capital city. WASAC is a government company that provides water to Kigali City and all urban centers of the country.
Expected to be completed by July 2015, the new water treatment facility will help Kigali close this gap as Culligan will design the system to produce 25,000 m3/d upon the plant's commissioning with the ability to expand capacity to 39,000 m3/d once performance results are proven. The expanded production will help Kigali meet future water demand.
"Kigali needs about 100,000 cubic meters of water per day (m3/d) while water supplied is 65,000m m3 per day, which implies a shortage of about 35,000 m3 per day," said WASAC chief executive officer James Sano.
Designed as a full turnkey project, Culligan will provide all design and engineering works, equipment supply, civil works, and installations. The plant will draw on the Nyabarongo River -- Rwanda's largest river and part of the upper headwaters of the Nile -- as its raw water source.

The treatment system is made up of raw water intake from the river including screening, a raw water intake pump station, sedimentation tank, aeration tank, raw water pump station, Culligan Omni Filtration (OFSY) Systems, disinfection, and a 1,000-cubic-meter treated water reservoir.
With the Culligan OFSY filtration system, the plant is equipped to deal with the challenges presented by the feedwater, which has very high turbidity as well as high iron and manganese levels. The 2-stage pressure tank filtration OFSY system offers several other advantages. For example, it removes Giardia and Cryptosporidium and other micro-organisms that are resistant to chlorine disinfection, as well as other contaminants such as arsenic, iron and manganese in the water.
In addition, the OFSY filtration system has a 60-percent smaller footprint compared to traditional gravity filtration technologies, allowing for a smaller size treatment plant resulting in lower CAPEX. Chemical usage may be lowered from 30 to 90 percent lower, which can reduce OPEX.
