WATER PROCESSING CYCLE
NZOWASCO employs full conventional water treatment processes
Water source
- Water sources include all rivers along Nzoia which includes Rivers; Kuywa, Kapolet, Kibisi
Intake structures
- Intake structures are all built along rivers for abstraction of raw water
- Raw water is pumped or gravitated to the treatment works through raw water mains
Treatment works
- Water is mixed with Alum
- Water is allowed to flow into flocculation basins
- Water flows into the segmentation basin
- Water flows through filtration units (Sand filters) to trap suspended materials
- Filtered water is allowed to flow to clear water reservoirs
- Chlorine is dossed into water at entry point for disinfection
- Water is now pumped to the storage tank ready for release to distribution lines
Water supply is composed of the following treatment process as illustrated on the diagram below:
