Raetihi sewerage/stormwater reticulation upgrading
Council is currently carrying out investigation work to locate sources of stormwater infiltration into the sewer system, either from faulty pipework or from illegal connections. This infiltration causes sewage overflows and impairs the quality of treatment. Council has engaged a Wellington-based company to carry out property inspections, and conduct smoke, dye and flow testing of the sewers. Apart from the location of infiltration, this information together with closed circuit television inspection work will be used to determine the necessary capital upgrading of the sewer and stormwater systems. Some major problems have been found in manholes with severe leakage, lack of haunching (the concrete sealing around joints), poorly fitted and semi-blocked pipes and several with lids buried up to 100mm below road seal level. Construction work for the 1995/96 stage, is due to start in March and continue to the end of April.
