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 an agile team with a clear and specialised expertise—resulting in efficient pricing, fast turnarounds, and premium quality.

​

Across much of the Yass Valley, wastewater must be treated and managed on the property itself. 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 Council to understand, and includes:

• 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

​

We also carry out system performance testing and effluent sampling throughout the Yass Valley. These tests check key indicators such as nitrogen, phosphorus, E. coli and BOD. Results are explained in plain English so landowners, builders and Council officers know exactly how the system is performing.

​

With over 15 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.

​

Southern Wastewater Consulting is an independent local business committed to making wastewater reporting simple and stress-free for property owners, designers and developers across the Yass Valley.
