8.4 Water Supply
A preliminary trunk and ring mains layout has been prepared, connecting into mains supply proposed along Castle Peak Road. These serve all development areas. Initial supplies prior to mains construction would come from existing deep wells. Anticipated demand from public mains would eventually be on the order of 18,500m3/day. Livestock and irrigation supplies would come from sewage treatment works and water retention ponds: estimated at about 10,240m3/day.
8.5 Sewerage and Sewage
Disposal
A comprehensive sewerage system has been designed for San Tin, culminating in a central Sewage Treatment works. In addition, Five "Sewage Package Plants" are proposed for livestock rearing zones to safeguard water quality.
SAN TIN
8.6 Roads
Trip generation within (and outside) San Tin has been calculated according to proposed land
use, population estimates, regional attractions and site characteristics. These figures have been applied in setting out trans- port corridors, intersections, and connections within the study area.
The proposed New Castle Peak Road bisecting San Tin will obviously greatly influence the quality of San Tin life. In order to minimize visual, noise, and air pollution side effects, and to encourage pedestrian flow across this major artery, much emphasis has already been placed on roadway alignment and design coordination with Government's Consultant Highway Engi- neers. From a community planning viewpoint, continued close collaboration toward a site and resident population-sensitive throughroad design is seen as being critical.
Two interchanges are proposed within the study area: one at the Lok Ma Chau inter- section and the other in the Western Valley Area. This will effectively eliminate disruptive feeder road movement through the Town Centre, resulting in a more pedestrian-oriented, habitable scale of design. (Two interchanges are an absolute must for San Tin as it has been designed.)
Footpaths and cycleways are laid out through the open space systems, providing a safe, pleasurable experience separated from roadway corridors.
