Technical Report WRD91026 Viewed at 15:07:48 on 29/07/2010 Page 33 of 107. 3.5 RESULTS FROM ASSESSMENT The 60 kL storage 'cank located near Merl 1 is not being utilised to its full capacity. It currently can gravitate water to Obiri at up to than the 0.5 Lis \,ith negligible water pressure. This is less current estimated demand at Obiri (0.7 Lis). The tank also can supply storage to ~!erl 1 through the use of a booster pump. It is usually by-passed for water supply to these locations, and so services the Border Store only. This tank should be moved to a position adjacent the treatment and pump house, where it can service Merl 1 and Obiri. The system was analysed for future growth with the 60 kL tank in this new location. Hydraulic analysis of the proposed system showed that: For a 10% visitor ,,,rowth rate per annum; 1. the following pipelines would reach their maximum capacities as follows (ref'ar to Diagram 2 for pipeline nomenclaturel TIl1E PIPELINE in three years DeB in six years JM in seven years MN in eight years BJ when JM is replaced the Border Store should be connect,ed to this new main also. 2. the storage capacity (when improved to 163 kilolitres) in the system can supply the peak daily demands for the next 4 1/2 years. For a 30% growth rate per annum; 1. the following pipelines would reach their maximum capacities at various times as follows: 005MJ
