 Water supply and Sewerage services in urban areas have in the past commonly been provided by monopolized Municipal Councils under the previous Local Government Ministry. As part of a general move by the sector to shift to market-led systems by restructuring the sector, a new paradigm emerged to transform water utilities into more modern service delivery companies that emphasize on operational and financial sustainability. This report presents findings on attributes of a well-run Water Treatment Plant as of KIWASCO and attempts to identify important factors that influence its performance. The scope is also largely oriented to water utilities that serve urban communities, but with varying characteristics and service objectives.

    ABSTRACT Most people living in rural communities, have no access to good domestic water for consumption. The inhabitants depends on rain water, well water and sometimes surface water for consumption. Improper treatment of water gotten from these sources, can lead to the spread of water borne diseases, because, sometimes the water gotten from these... Continue Reading
