4 1. INTRODUCTION. THESE TERMS OF REFERENCE ARE FOR SOLICITATION OF A SUITABLE INVESTING FIRM TO DESIGN, BUILD AND OPERATE PLANTS FOR DESALINATION OF SEAWATER FOR MOMBASA COUNTY. THE TOR SETS OUT THE BACKGROUND, THE OBJECTIVES OF THE PROJECT, SCOPE OF WORKS AND OUTPUTS EXPECTED FROM THE PROJECT THE TORS ALSO PROVIDES FOR THE REQUIREMENT IN RESPECT TO TECHNICAL CAPACITY AND MANDATORY REQUIREMENTS. 2. BACKGROUND: The Water Supply in Mombasa County is 48,000M 3 per day against a demand of 180,000M 3 per day, experiencing a Water Supply deficit of almost 73% and competition for water supply from stressed water sources; Baricho Water fields, Marere Springs, Mzima Spring and Tiwi Boreholes which are located far way and outside the County. Rationing is the order of the day. This scenario made the County to come up with a proposal for a Desalination project to address water supply related challenges at both the urban and rural areas of the County. The County is rich of sea water which if exploited could supplement the deficit or improve accessibility by far. Desalination project target installation of desalination plants at various sites within the County before the end of 2017 and this would need an input of an experienced investing firm to design, develop and operate the desalination plant. The daily amount of desalinated water is estimated at 270,000m 3 ; (70,000m3/day for Likoni, 100,000m3 /day for West Mainland and 100,000m 3 /day for the North Mainland) depending on the consumption and hydraulic capability of the distribution network. 4
