Raetihi water supply improvements need landowners' assistance
Raetihi' s dirty water will need a new treatment system to completely eliminate the problem, Ruapehu
council staff have found. However, they have implemented some land-use changes that could allevi-
ate the problem in the shortterm, they report. Council staff have been investigating the recent
discolouration of the supply and the means of preventing a future recurrence of the problem. Walk-over surveys of the water supply catchment have been conducted and the cooperation of the landowners sought to implement land-use practices that minimise soil erosion. "These residents appreciate the problem and wish to cooperate with council to effect the improved security of the supply," said council CEO Cliff Houston. In one location this will involve the digging out of a settling pond in the coming summer period; in another location the replanting of grass on a paddock previously ploughed for horticultural use; in another location the property owner plans to carry out barley planning after the carrot harvest in March/April to stabilise the soil. The council is also investigating upgrading the intake settling ponds to increase their performance. "But the best long term solution is the construction
of a comprehensive treatment plant," said Mr Houston. 'This proposal will be developed forconsideration in the 1996/97 Draft Annual Plan. A comprehensive treatment plant is seen as a necessity to ensure the provision of a safe supply for Raetihi." Chemical tests of the water at the time of the contamination showed no health-threatening contamination, assured Mr Houston.
