Although micro filtration and U.V. light treat the water, the water is not chlorinated and therefore sensitive to E-coli contamination should it enter any part of the Scheme. Members must understand that no one can give any guarantee over the quality of water supplied in a scheme like that of the Fernridge Scheme. The FWSA is to use its best endeavours to ensure continuity and quality of supply. This is achieved by regular checking of the Scheme and testing of the water.
From this Reservoir the water is gravity fed into the Schemes PVC pipe reticulation system to the properties of Association members. The reticulation system covers Tararua Drive, part of Upper Plain Road, Burnetts Road, Evans Road and Skeets Road. Each property that receives Fernridge water has a Toby Unit, which contains a restrictor valve and a flow meter, and is required to have the water fed into a storage tank. The storage tank should have a minimum 25 mm air gap between the bottom of the incoming supply pipe and the top of the overflow pipe. The overflow should also be screened with fine gauze to prevent entry of airborne contaminant.
