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.
