Effluent Reuse Scheme (ERS) Upgrade

This $11 million project replaced and upgraded much of Karratha’s ageing recycled water infrastructure to ensure all existing and future planned public green spaces are watered more frequently and with higher quality treated recycled water.

Project overview:

The City of Karratha’s Wastewater Network is a large-scale water distribution system that supplies treated recycled water sourced from the Water Corporation’s wastewater treatment plants (WWTPs) to a number of grassed open space areas within the City of Karratha.

The City of Karratha, in association with the Water Corporation, LandCorp and Pindan, upgraded the existing network to provide an improved and sustainable recycled water supply, which reduced the reliance on potable water.

This $11 million project replaced and expanded ageing recyled water infrastructure to supply higher quality treated recycled for use in grassed public open spaces within the City of Karratha.

The 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.
