It has a through flow of 42,000m3/day. Of the total capacity, only 20,000m3/day is obstructed through shallow boreholes and the Pipelines serving Ukunda and Likoni in Mombasa ii) Msambweni Catchment: this covers about 42 km2 with a through flow of 27,440m3/day. Currently 17,800m3/day is obstructed through over 251 shallow boreholes. • The two aquifer can be developed further to expand domestic water supply for expanded residential and commercial housing in Kombani, Diani/Ukunda and Msambweni Other Water Development Opportunities • Medium size dams along upper sections of Ramisi, Pemba and Mwache rivers in the ASAL areas to provide water for domestic use, small scale irrigation and ranching activities • Development of large water storage tanks along existing pipelines serving Kwale, Kinango and Diani/Ukunda towns Sanitation Investments in Kwale • As the main urban centres, Diani/Ukunda and Kwale towns lack proper sewerage systems and depend on septic tanks and pit latrines, • The County Government will design a sewerage system for Diani Ukunda in Financial year 2014/15. • The town has population of over 85,000 people, • Once design is complete partners will be invited to partner in developing the sewerage system • Kwale town equally requires a central sewerage system
