Kenya Towns Sustainable Water Supply and Sanitation ProgramIntroductionThe Ministry of Water and Sanitation & Irrigation received financing for the implementation of Kenya Towns Water and Sanitation Programme from The African Development Bank.The main objective of the program is to improve the access, quality, availability, and sustainability of water supply and wastewater management services in multiple towns in Kenya, with a view to catalyzing commercial activities, driving economic growth, employment creation, improving quality of life of the people and building resilience against climate variability and change.Projects Under AWWDA ClusterProject InformationAthi Water Works Development Agency (AWWDA) is implementing projects under Kenya Towns within its area of jurisdiction, and in areas covered by the Coast and Tanathi Water Works Development Agencies (WWDA). AWWDA will lead the implementation of sub-projects within, Coast and Tanathi WWDAs areas.The WWDAs have signed Implementation agreements where AWWDA will be the implementing agency. However, responsibilities for execution will be shared between AWWDA, CWWDA and TWWDA in the respective Water Works areas. TAWWDA and CWWDA will oversee the day to day implementation of the projects within their areas of jurisdiction.Progress of Activities to DateThe implementation of the different components of the program are at different stages of as outlined below:ConsultanciesProgress on consultancies within the programme is summarized below;Water Works Development AgencyProject NameAWWDAConsultancy on design review and construction supervision of Kikuyu and Limuru water and Sewerage ProjectsConsultancy on design review and construction supervision of Gatundu Water Supply and Sewerage ProjectConsultancy for design and supervision of Kiambu and Ruaka water and sewerage worksConsultancy for detailed design and construction supervision for Makutano water and sewerage projectCWWDAConsultancy on design review and construction supervision of Pemba Intake and Changamwe repooling sewer networksConsultancy Services for Design Review and Supervision for Construction of Water Distribution Works for Malindi Water Sewerage Company- Watamu Town Lot 2A Works in CWSB Area.TAWWDAConsultancy on design review and construction supervision of “Design and Build” of Machakos Water Supply and Sewerage Project.Review of an addendum to the contract to amend it from “Design and Build” framework to a conventional “Design and supervision” contract is ongoing between the consultant and AWWDA/TAWWDA.Consultancy on design review and construction supervision of Mwala – Mbiuni Water Supply and Sewerage Project.Consultancy on the feasibility study, detailed design and tender documentation for Oloolotikosh Dam water and sanitation project.Consultancy on feasibility study, detailed design and tender documentation for Mwania and Miwongoni dam water and sanitation project.Consultancy Services for Carrying Out Feasibility Study, Preliminary Designs & Detailed Design Reports for the Proposed Ongata Rongai, Ngong & Mavoko Sewerage Infrastructure Project in Tanathi Water Services Board Area.Consultancy for detailed design and construction supervision for Kitui and Matuu Last mile connectivity project.AWWDA/CWWDA/TAWWDAConsultancy services for projects communication and documentary.Consultancy Services for Sustainability Study for WSPs (CWSB, AWSB, TAWSB)AWWDA/TAWWDA/RVWWDA/NWWDA/LVNWWDAIndependent Panel of experts for implementation of Kenya Towns Sustainable Water Supply and Sanitation Program.Consultancy Services for Monitoring and Evaluation of Kenya Towns- Athi Cluster Projects.Consultancy Services for Implementation of County Strategy, Capacity Building of Counties, Inspectorate Services, Media Communication and Advocacy for WASREB, and training of WWDA/County staff.Consultancy Services for Training of WRA and Community, Enforcement of Compliance and Water Quality Regulation and WRUA'sConsultancy Services for Development of County Atlases (Kericho, Kajiado and Embu) for WASREBWorks ComponentsProgress on works components within the programme is summarized below;Water Works Development AgencyProject NameProject ScopeAWWDAonstruction of Gatundu Water Supply and Sewerage ProjectConstruction of 40km of the trunk and reticulation sewers, sewage treatment plant of capacity 3,000m3/d, and three water supply schemes as follows; Ruabura 4,000m3/d, Ng’enda 4,000m3/d and Handege 9,000m3/d, 5 ablution blocks and 2000 connections… Construction of Kikuyu water and sewerage projectConstruction of 50km of trunk and reticulation sewers with sizes ranging from DN 250 – 450mm PVC/uPVC pipes, 26km of HDPE water distribution network, 3 no. ablution blocks, 6 no. boreholes with 48m3 pressed steel tanks and 450 household connections.Construction of Limuru water and sewerage projectRehabilitation of the existing wastewater treatment plant, construction of 2 no. oxidation ditches, 4 no. settling tanks, sludge beds, 40km of extension sewers with sizes ranging from DN 250 – 300mm uPVC pipes, 25km of HDPE water distribution network, 3 no. ablution blocks, 6 no. boreholes with 48m3 pressed steel tanks and 450 household connections.Construction of Kiambu and Ruaka water and sewerage worksRehabilitation of the existing waste water treatment plant, construction of 108km of trunk and reticulation sewers ranging in size from DN 250 – 450mm covering areas of Kiambu and Ruaka, 25km of HDPE water distribution network, 4,000m3/d Kiameru water scheme, 4 no. ablution blocks, 6 no. boreholes with 48m3 pressed steel tanks and 450 household connections.Construction of Works for Makutano Water and Sewerage ProjectMakutano SewerageLaying of 12.5km of 600/450/300 dia.
