stream flow into Perth’s drink­ing wa­ter dams – but this is the amount Perth con­sumes on a hot sum­mer’s day, ac­cord­ing to Wa­ter Cor­po­ra­tion spokes­woman Clare Lu­gar.

“De­clin­ing rain­fall over the past decade has meant the soils in our catch­ment ar­eas are a lot drier than they used to be and act like huge sponges, soak­ing up the rain­fall,” she said.

“Our catch­ments need a lot more rain­fall to soak into the soils and then re­lease wa­ter into streams that flow into our dam.”

Last fi­nan­cial year, Perth’s dams only pro­vided 7 per cent of to­tal wa­ter sup­ply. De­sali­na­tion was the largest source of wa­ter at 47 per cent and ground­wa­ter formed 46 per cent.

Ser­pen­tine Dam con­trib­uted about 9 bil­lion litres last fi­nan­cial year, which is about a bil­lion more than the pre­vi­ous year.

“We want to re­mind the com­mu­nity the two-day-per-week sprin­kler ros­ter is cur­rently in place across Perth, so en­sure your sprin­klers are set for the cor­rect day and only op­er­ate be­fore 9am or af­ter 6pm,” Ms Lu­gar said.
