Overview
Dalwallinu wastewater treatment plant in Western Australia serves 334 people with secondary treatment. It discharges 86.40 megalitres annually, supporting local sanitation in a rural inland setting.
The Dalwallinu wastewater treatment plant is located in the Shire of Dalwallinu, Western Australia, serving a small population of 334 residents. The facility operates under secondary treatment, a standard level for small inland communities in Australia, ensuring effective removal of organic matter and suspended solids before discharge. As a secondary treatment plant, it meets the typical requirements for small agglomerations under Australian wastewater regulations, which are enforced by state environmental authorities. The plant's discharge volume of 86.40 megalitres per year reflects its modest scale, consistent with the population served. The treated effluent is discharged into the local environment, likely into a nearby watercourse or groundwater system. The plant plays a key role in protecting the region's water resources, as the area is part of the inland drainage basin of Western Australia, where water conservation and quality are critical for agriculture and ecosystems.
Environmental context
The plant discharges into the inland drainage system of Western Australia, a region characterized by semi-arid climate and ephemeral waterways. The treated effluent supports local water balance and may recharge groundwater or flow into seasonal creeks that eventually drain to salt lakes or the Indian Ocean via the Murchison River system. Protecting these water bodies is vital for native flora and fauna adapted to intermittent flows.
