The City of Mandurah is developing a large-scale waste-water reuse scheme for irrigation of the northern sector of its public open space. It is planned to recover up to 2 GL/annum of water from the Gordon Road Waste Water Treatment Plant, which recharges water to the Superficial Aquifer.
In 2016, Rockwater completed a hydrogeological review and risk assessment for the project following the national MAR guidelines. This was used to develop reuse scheme options.
In 2018-19, we designed and supervised the construction of eight monitoring bores to measure water levels and water quality in the groundwater mound created by the waste-water treatment plant.
A groundwater model was then used to determine a sustainable volume that could be allocated to the City, and the best methods of its recovery and distribution. It is anticipated that scheme will be implemented following approval by the regulator.
