Suswa water supply project

Project Detail

  1. Project Background

Rift Valley Water Services Board is implementing projects to supply water and sanitation services to mitigate against the effects of drought in the area its jurisdiction with funds from the International Development Association and the Government of Kenya which was channeled through Lake Victoria North Water Services Board. The projects include drilling of boreholes, construction of water supplies from these boreholes, rehabilitation and expansion of water supplies, drought mitigation studies, provision of equipment for drought mitigation including water bowsers, vehicles, mobile water treatment units, tetrameters’ for sitting boreholes, collapsible tanks and construction of rain water harvesting structures of rain gutters and plastic tanks.

Among the projects being constructed is Suswa water project targeting to provide water services by providing 900m3/day of water from a borehole at DCK by pumping to a high ground within the Hell’s Gate National Park for gravity distribution through a 34Km distribution main piping and 8 Km of water service lines to Hell’s Gate, Masai Cultural Centre,   Olemayani Ndogo, Olemayani Kubwa, Narasha, Iseneto, Suswa Town and Olasiti. This project will benefit 28,000 people and 18,000 livestock units in the year 2027.

  1. Challenges
  1. The project is quite extensive; the pipeline is from DCK in Naivasha to Suswa town in Narok County. The gravity main is 34km long.
  2. The communities living in the project area have made so many demands and have severally stopped the contractor from working.
  3. Hells Gate National park has restricted areas where the contractor cannot interfere.
  4. The contractor has to comply with all the rules and regulations of the park.
  5. The contractor is experiencing challenges in construction of trenches because of the loose formation and very fine soils and during rainy season the trenches become weak points to start forming gullies.
