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, are upgrading the existing netwrok to provide an improved and sustainable recycled water supply to all existing and future planned open green spaces throughout Karratha.

The Wastwater Network Upgrade will have improved capacity and functionality to supply treated water on a prioritised basis to each open space area which will ensure effective and sustainable use and management of this valuable resource.

The City of Karratha will have ownership of the new infrastructure and be responsible for its ongoing operation and maintenance.

Site preparation works for the project commenced this month 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 the next nine months 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 treated water.

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.
