Ex­pan­sion still in pipe­line

Joondalup Times - - NEWS - Lucy Jarvis

THE Wa­ter Cor­po­ra­tion says its $21 mil­lion project to build a 13km recharge pipe­line and mon­i­tor­ing bores in Wan­neroo and Neer­abup is pro­gress­ing well.

The up­date on the Ground­wa­ter Re­plen­ish­ment Scheme came af­ter a Wan­neroo res­i­dent raised con­cerns that the project had stalled near Lake Joon­dalup.

“The project has not stalled and the over­all ex­pan­sion project is on track for com­ple­tion in late 2019,” Wa­ter Cor­po­ra­tion act­ing as­sets de­liv­ery gen­eral man­ager Nathan Hard­wick said.

Work on the un­der­ground recharge pipe­line from the Beenyup waste­water treat­ment plant in Craigie to the bores is ex­pected to fin­ish next July, while the bore con­struc­tion is ex­pected to fin­ish in April.

Mr Hard­wick said work would re­sume at the south­ern sec­tion of Studmas­ter Park, up to Ariti Av­enue, in early 2019, af­ter the rain­bow bee eater nest­ing sea­son fin­ished.

He said the pipe­line route was cho­sen to min­imise po­ten­tial en­vi­ron­men­tal im­pacts, with the first stages of work us­ing trench­less tech­nol­ogy in en­vi­ron­men­tally sen­si­tive ar­eas such as the Banksia wood­land in Wan­neroo.

“The sec­ond stage of work us­ing trench­less tech­nol­ogy be­gan in Septem­ber to in­stall a 1.4km sec­tion of pipe un­der­neath Beenyup Swamp, Perry’s Pad­dock and Studmas­ter Park,” he said.

“Work is on track to be com­pleted in Novem­ber.

“The next two stages of work will then take place in Wood­vale and Neer­abup, with work to be­gin in late Oc­to­ber us­ing tra­di­tional open trench meth­ods.

“Con­struc­tion of the deep un­der­ground bores and as­so­ci­ated above­ground in­fra­struc­ture be­gan in De­cem­ber 2017 and is due for com­ple­tion by April.”

Mr Hard­wick said ground­wa­ter re­plen­ish­ment was part of the longterm ‘Wa­ter For­ever’ plan to se­cure wa­ter sup­plies in re­sponse to cli­mate change.

He said the recharge pipe­line would trans­fer treated, drink­ing-qual­ity wa­ter from the Craigie wa­ter re­cy­cling plant to the recharge bore site.

“The first 14 bil­lion litre stage of the Ground­wa­ter Re­plen­ish­ment Scheme be­gan recharg­ing to aquifers last year,” he said.

“The ex­pan­sion cur­rently un­der way will dou­ble the scheme’s ca­pac­ity to be able to recharge up to 28 bil­lion litres of wa­ter per year.” d487278
