Karratha (WA) is receiving a major upgrade to its recycled water irrigation network with a project undertaken by Cobey Industries.

The $11million project includes replacing and expanding the ageing recycled water infrastructure currently in place. The project will also see all existing and future planned public green spaces are watered more frequently and with higher quality treated recycled water, making the town more sustainable.

City of Karratha Mayor, Peter Long, said the upgrade would significantly improve the city’s use and management of water and help facilitate the growth of Karratha and its public open spaces.

“At the moment most of our parks and ovals are irrigated with either lower quality recycled water or potable drinking water which can be costly to the City and is not the best use of this limited water supply,” Cr Long said.

“This upgrade will see most of the pipe network and pump stations used to irrigate the City’s green spaces replaced to ensure they are watered with high quality recycled water delivered directly from the Water Corporation’s Wastewater Treatment Plant.”

“The project also incorporates the introduction of intelligent irrigation technology which is able to respond tank water levels and irrigate spaces on a priority basis, so parks and ovals that require regular irrigation still receive water when supply levels are low.”

Site preparation works for the project commenced in October with the establishment of temporary site offices near the Karratha Country Club, removal of the existing pump station storage tank at Bulgarra Oval, preparation of pump station sites at Kevin Richards and Tambrey Reserves and boring installation of pipelines at locations along Searipple Road.

Over nine months the pump stations at Cattrall Park, Millars Well Oval, Tambrey Oval, Brogla Park and the City Centre will also be replaced and more than 9 kilometers of new pipeline will be laid, linking the new pump stations with the supply of high quality recycled water.

Bulgarra Oval and the Karratha Country Club is already irrigated with high quality recycled water from the Water Corporation’s Wastewater Treatment Plant.

The irrigation project is funded through the State Government’s Royalties for Regions Pilbara Cities fund, administered by the Pilbara Development Commission, Water Corporation LandCorp, Pindan and the City of Karratha.

The project is estimated to be completed by mid-2016.
