Eildon Wastewater Treatment Plant | Secondary Treatment in Victoria, Australia

Eildon Wastewater Treatment Plant is a secondary treatment facility located at 997 Back Eildon Road, Snobs Creek, Thornton, in the Shire of Murrindindi, Victoria, Australia. The plant serves a population of approximately 1,359 residents in the Eildon area, a small town situated near Lake Eildon, a major recreational water body. As a secondary treatment plant, Eildon WWTP provides biological treatment to reduce organic matter and suspended solids. The plant operates under the regulatory framework of the Victorian Environment Protection Authority (EPA), which issues discharge licenses under the Environment Protection Act 2017. For a small agglomeration of this size, secondary treatment is the standard requirement to protect receiving water quality. The treated wastewater is discharged into the local waterway, which ultimately drains into the Goulburn River system. The Goulburn River flows into the Murray River, a vital water source for agriculture and ecosystems in the Murray-Darling Basin. The plant plays a key role in safeguarding downstream water quality, particularly for recreational uses at Lake Eildon and irrigation along the Goulburn Valley.

The plant discharges into the Goulburn River catchment, which feeds into the Murray River, part of the Murray-Darling Basin. This basin supports extensive agricultural irrigation and diverse aquatic ecosystems, including native fish species such as Murray cod and golden perch. The region's seasonal rainfall and low flows in dry periods make nutrient management critical to prevent algal blooms and maintain water quality for downstream users.
