Southern Wastewater Consulting supports development across the Yass Valley by preparing clear, compliant wastewater reports for properties that aren’t connected to the town sewer network. Our work ensures development applications meet Yass Valley Council’s on-site sewage management (OSSM) requirements for homes, rural dwellings, secondary cabins, subdivisions and commercial projects.

We are a locally operating and specialised team delivering quality and compliant wastewater assessments throughout the Southern Tablelands. Ready to start the process? Contact us on info@southernwastewater.com.au or 0435 575 403. 

​

Across much of the Yass Valley, residential and commercial developments occur on unsewered land which means wastewater must be treated and managed on the property itself. When this is the case, Council requires a wastewater management plan as part of the approval process, and our role is to show—through practical design and evidence-based assessment—how your land can safely treat and dispose of effluent without impacting neighbours, waterways or the environment.

​

We prepare wastewater reports for a wide range of development needs, including:

• New houses, rural lifestyle dwellings and granny flats in unsewered areas

• Replacing or upgrading older systems that no longer meet standards

• Boundary adjustments and subdivision proposals

• Commercial and tourism ventures such as cafés, farm stays, wineries, schools and event venues.

​

Every report is designed to be straightforward for applicants and secure Council compliance. They include:

• A detailed soil and site analysis

• A wastewater system design that fits the landform, soil, setbacks and operational needs

• A scaled plan showing effluent disposal or irrigation areas, buffers and required separations

• Clear recommendations on suitable treatment options such as septic systems, AWTS, composting units, greywater systems, absorption trenches or irrigation layouts​

​

With 20 years in wastewater assessment, geology, soil science and regulatory compliance, our priority is to deliver technically sound, practical reports that Council can assess quickly.

​

We work throughout the Yass Valley region, including Yass, Yass River, Murrumbateman, Binalong, Bowning, Bookham, Gundaroo, Sutton, Nanima, Jeir, Springrange, Good Hope, Marchmont, Bellevale, Lade Vale, Berremangra, Burrinjuck, Woolgarlo, Mullion, Cavan, Wee Jasper, Goondah, Boambolo, Hillgrove, Illalong Creek, Galong, de Burghs Bridge, and surrounding rural localities.
