Water West is delivering a wastewater treatment and recycling scheme for Satterley Property Group’s new masterplanned community in the Perth Hills known as the North Stoneville Townsite.

North Stoneville will include over 1,400 residential lots across four villages, with commercial centres, two schools, including a high school and extensive open space areas for active and passive use, including significant conservation areas.  Over 3,500 people will live in North Stoneville when the project is complete.

Water West will manage the design of a reticulated wastewater conveyance network using pressure sewer technologies, linking properties to a wastewater treatment recycling plant (also known as a recycled water plant).  Pressure sewer was proposed by Water West and agreed to by Satterley Property Group given the undulation of the site’s topography and the potential for significant rock underling the site.  The pressure sewer approach removes the need for deep trenching associated with gravity sewer design, allowing the sewer network to follow the landform; this has material benefits to the developer in terms of masterplan design by removing the need for benching and also avoids the costs associated with deep trenching, especially where rock may underlay the site.

All wastewater conveyed through the pressure sewer network will be treated at a recycled water plant to be built by Water West within the North Stoneville Townsite.  Water West’s recycled water plant will generate water which will then be used for public open space irrigation.  100% of all wastewater from the North Stoneville community will be recycled and with 100% of the North Stoneville Townsite’s public open space irrigation will be met by Water West’s recycled water.

Water West commenced design in late 2019 and expects to make applications for approvals mid way through 2020.  Construction of the scheme is forecast to commence in early 2021 and to be operation by late 2021.
