Kwinana Water Reclamation Plant
Summary
The Kwinana Water Reclamation Plant (KWRP) is a joint initiative of the Water Corporation and the Kwinana industries to achieve the double benefit of greater overall water efficiency and reduced process water discharges into the Cockburn Sound. A micro filtration/reverse osmosis unit has been built (at a cost of A$ 25 million), which takes secondary treated effluent from the nearby Woodman Point wastewater treatment facility to produce a low TDS (Total Dissolved Solids) water supply.
The produced high quality process water is initially used by CSBP, Tiwest, Kwinana Cogeneration Plant, BP and HIsmelt to replace scheme water (6 GL/year, about 2-3% of the total scheme water use in the drought-affected Perth metropolitan area). The low TDS enables the process plants to cut chemicals use in cooling towers and other process applications, thereby reducing metal loads in their effluents. In exchange for taking water from the KWRP, the industries will be able to discharge their treated effluents into the deep ocean outfall through the Water Corporation pipeline, thereby eliminating process water discharges to the sensitive Cockburn Sound (Water Corporation 2003).
