This system has 4 km of pipe. The main pipeline runs from the spring tank to the reservoir tank. Because of the large drop between the spring tank and the pipe bridge PVC pipe (rather than the usual polyethylene) was used to cope with the large pressures. Due to the topography a break pressure tank was not included in the design. A galvanised steel pipe bridge spansa river at the lowest point below the spring tank.
