These comments reference two important engineering aspects are directed towards the Planning Inspector and concern the acknowledged high water table across the selected land and the potential additional provision for effluent / grey water treatment.
1. Recent studies have concluded that static pumps will be required to deal with excess surface water. Calculations are now required to verify potential volumes - any developer should be required to build this provision into his/her bid.
2. The hydraulics calculations for carrying effluent / grey water from 50 + 250 = 300 new houses need to be undertaken by an independent specialist consultant who can advise upon the engineering requirement and recommend a potential solution with headline costs. In my opinion, it is unsafe for CDC to simply 'take Southern Water's word for it.' It will be money well spent to enlist independent verification of their statement at this early stage. The last thing the residents of Bosham and other shore side villages wish to see is untreated effluent in Chichester Harbour.
