Mwache River Dam Project
• Dam Construction along Mwache river –
Feasibility for a concrete gravity dam with a total
reservoir capacity of 135 million m3 was
undertaken and the World Bank intends to
finance the project
• Proposed Financing from the World Bank does
not include construction of Water Treatment
Plant and distribution lines to Mombasa and
Kwale.
• The project feasibility proposes and 2,000 – 3,000
ha irrigation project which is open to investors
Pemba Dam Rehabilitation Project
• Initial Pemba dam and treatment works was
established in 1980 and ceased operations in
1983,
• The project stopped operations due to siltation
and failure of pressure filters.
• A new dam and 6,000 cm3/day treatment works
have been proposed and feasibility undertaken,
• The project targets to supply water to Kinango
town and neighboring areas
Dam Construction along River Umba
• A concept note has been developed for this
project by the Coast Development Authority
• The upper section of the river above Makwenyeni
village is the proposed dam site,
• The dam is targeted to supply domestic water to
Lungalunga border town and other areas in Vanga
ward
• It can also support expansion of irrigation
projects along Umba river basin from 600 – 6,000

Development of underground Water
• Two underground catchments have potential for
commercial exploitation:
• i) Tiwi Catchment: The aquifer has a width of 20 km with
good quality water. 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
