Run-off at low­est lev­els

Cockburn Gazette - - NEAR YOU -

RAIN wa­ter run-off into Perth’s dams has reached a record-low for this time of year, ac­cord­ing to the Wa­ter Cor­po­ra­tion.

Spokes­woman Clare Lu­gar said the 2.3 bil­lion litres of run-off into our dams be­tween May and July was the low­est since records be­gan in 1911.

“We are of­ten asked if the dams are full af­ter a few days of rain and we re­mind peo­ple that in our dry­ing cli­mate our catch­ments must be com­pletely soaked be­fore they pro­duce any de­cent runoff,” she said.

Over­all, the dams which sup­ply wa­ter to two mil­lion peo­ple in Perth are 27.7 per cent full, 3.6 per cent lower than in 2014.

Last month, Perth’s drink­ing wa­ter sup­plies were boosted by a $21.2 mil­lion up­grade to the Jan­dakot Ground­wa­ter Treat­ment Plant and a new bore.

Wa­ter Min­is­ter Mia Davies said the lo­cal plant could now treat up to 60 mil­lion litres of wa­ter a day, up from 40 mil­lion litres.

She said the ex­tra ca­pac­ity would cater for the wa­ter pro­duced by the new bore, which draws the re­source from 800m be­low the sur­face from the deep Yar­ra­gadee aquifer.
