A region-wide state of emergency has been declared for Southland following heavy rain and flooding and the failure of a water treatment plant has left a remote town with eight hours’ drinking water.
Emergency Management Southland said at 7.30pm on Thursday the plant at Tuatapere had been inundated by floodwaters and has stopped working.
“Residents are advised to conserve water urgently. They can do this by not taking showers, washing dishes or flushing the toilet. The treatment plant cannot be repaired until the water recedes.
“Southland District Council is sending three water tankers to Tuatapere to provide drinking water until the plant can be repaired.”
In a statement earlier, announcing the state of emergency, Southland Civil Defence Emergency Management said, “MetService has extended the heavy rain warning until 8pm this evening. Around the wider Southland region, the immediate concern was Otautau community where the river level is expected to rise to near bridge height.
“Main Street is closed, and bulk filling on both sides of the bridge is underway to support the stop bank infrastructure. While the rain is easing, surface flooding across roads throughout Southland may be contaminated.”
People were urged avoid contact with the flood water as wastewater and stormwater systems across Southland towns struggled to cope with the volume of water. Staying at home and off the roads was also advised.
Community emergency hubs have been opened at the Croydon Lodge in Gore and the Mataura Community Centre for people who need assistance.
River peaks were expected to occur overnight and into tomorrow morning. It would take time for the surface water to recede, Civil Defence said.
Fire and Emergency has confirmed four households in Queenstown have been told to evacuate because of a landslip, and a house has been evacuated because of flooding.
