TARGETS FORWATER USE
Auckland came in 18 million litres below its water usage target amid destructive flash flooding on Sunday, but the city still faces weeks of possible threats to its supply. Aucklanders used 382 million litres of water on Sunday, making it the second consecutive day to come under the 400-million-litre target. But the city is not in the clear yet. Watercare’s Ardmore water treatment plant is treating 50 per cent less water than usual in the wake of the storms that battered the region over the past week. The water company says it will take many weeks for the silt in the Hunua Dams to settle, and until then the Ardmore plant remains under pressure. Water clarity at Ardmore was 100 times worse than it should be, Watercare said on Monday. Auckland residents have been advised to reduce their water usage by 20 litres per person a day until the end of March. Water savings are required because the stormhad vastly increased the amount of silt in the water and caused difficulties with water treatment, Watercare’s Mark Bourne says. If significant savings are not made, Watercare may be forced to release partially-treated water into the system, and a boilwater notice would be issued.
