It is recommended that the following changes be made to the pipeline system (refer to Diagram 2). TIME YEARS PIPELINE CH.:IINGE 3 DCB to lOO mm 6 JM,MN,BJ to lOO mm In 4 1/2 years time the service storage needs to be increased when the day demand would exceed the existing storage of 163 kilolitres in the system. The storage required in 10 years time is 243 kilolitres. The additional 80 kilolitres storage can be provided in 2 stages of around 40 kilolitres each, in 4 1/2 years time and 7 1/2 years time respectively. It is recommended that the additional storages be ground level tanks located near the treatment and pump house. The water from these ground level tanks would then be pumped to the elevated storages as required. This removes the high capital cost of providing elevated storage. 30% Visitor Growth Rate It is recommended that the following changes be made to the pipeline system. TIME YEARS in 1 4 PIPELINE DCB,JM,MN,BJ BN,JK CHANGE to lOO mm to lOO mm The peak daily demand would exceed the existing storage of 163 kilolitres in 1 1;2 years. The storage required at the end of 10 years is 1089 kilolitres. The additional storage required could be provided in stages. 005MJ
