Athi Water Services Board (AWSB) intends to construct a sewerage collection system and treatment plant in Kiserian, Kajiado County. The project is a fully funded Government of Kenya project that was initiated in 2007. The project that covers 50 hectares of land will benefit more than 150,000 households in Kajiado North and Kajiado West constituencies.

 

The project worth KES1.3bn will benefit residents of Kiserian, Ongata Rongai, Matasia and Ngong with a treatment capacity of 18,000 meter cubic of water per day and wastewater stabilization ponds. The project entails construction of a 17 metre high earth dam embankment, a spill way, intake tower and raw water main pipes.  The Kiserian Dam will be handed over to the Oloolaiser Water Service Company by the contractor.

The feasibility study, preliminary and detailed design was carried out by Norken Limited in association with Hydrosult Consulting engineers while the design review and construction supervision is being done by Gath Consulting Engineers together with Losai Management Limited. The force behind construction of the sewerage is to deal with the growing number of population in the county and need to prevent ground and surface water pollution due to reliance on pit latrines and soak pits.

 On August 21, 2015, Athi Water Services Board together with other stakeholders held a public meeting with Kajiado County residents. The objective of the meeting was to brief the public / beneficiaries of the project progress, highlight positive and negative impact of the project and measures put across, and to obtain feedback/ additional views from the public as regards to the impacts and mitigation measures.

AWSB representatives made a technical presentation on the Kiserian Sewerage Project and National Environment Management Authority (NEMA) on Environment and Social Impact Assessment.  This brought mixed reactions from residents who wished to know whether the expansion plans are in place for phase two of the system, effluent discharge arrangements and benefits of the project for people living around specified areas where the dam will be put up.

Residents insisted that the board should foresee that the local youths are given direct jobs to avoid idleness in the area. A representative from Oloolaiser Water Service Company, which is in charge of water distribution in the region, enlightened residents on the Water Resources Users Association (WRUA). This Association is a community based voluntary organization formed around a specific water resource for management and harmonious use of water.  WRUA’s are run through support of Water Resource Management Authority (WRMA).

In conclusion, residents were assured protection of resources surrounding the area covering the project and openness in construction of the sewer project.
