On-site wastewater reports and OSSM assessments in Goulburn Mulwaree Council and the Southern Tablelands

Southern Wastewater Consulting prepares fully compliant, Council-ready wastewater reports for Goulburn Mulwaree Council development applications. We specialise in on-site wastewater assessments for properties not connected to sewer, ensuring your application meets local approval requirements.

For wastewater reports compliant with Goulburn Mulwaree Council and other Southern Tablelands Councils, contact us by calling 0435 575 403 or at info@southernwastewater.com.au.

If you’re building in the Goulburn Mulwaree Council area in an area not connected to sewer, a wastewater assessment (OSSM) will be required to secure project approval. Our reports detail how wastewater will be treated and disposed of safely on your land, protecting soil, water quality, and community health.

 

We provide wastewater reports for Goulburn Mulwaree Council covering:

  • New homes, cabins, secondary dwellings and granny flats in unsewered areas

  • Extensions and developments that increase wastewater loads

  • Replacement, relocation or upgrades of existing septic and wastewater systems

  • Subdivisions and boundary adjustments

  • Commercial, tourism and rural developments, including farm stays, cellar doors, breweries, distilleries, schools and accommodation

The following is included in your assessment to secure Council's approval

  • Onsite site and soil testing to assess soil conditions, slope, drainage and other property constraints

  • A wastewater design suited to your site, proposed development and preferred system type

  • A scaled site plan identifying wastewater disposal areas, setbacks, buffers and key site features

  • Advice on suitable treatment and disposal options, including septic systems, AWTS, composting toilets, greywater, absorption and irrigation systems

  • A clear, council-ready report documenting the assessment, proposed design and recommendations for approval

Each Goulburn Mulwaree-based on-site sewage management system report (OSSM) includes soil testing, site investigation, and a detailed layout map. We design systems to suit local conditions, recommending solutions such as septic tanks, Aerated Wastewater Treatment Systems (AWTS), greywater reuse, composting toilets, absorption trenches, or irrigation fields.

With 20 years’ experience in wastewater consulting, soil assessment, geology, and environmental compliance, we focus exclusively on wastewater reporting and assessments – giving you accurate, practical reports that meet Goulburn Mulwaree Council requirements.

Our three step method

  1. Email Info: A site plan or early layout can help, but it’s not essential. We’ll let you know exactly what we need so everything stays straightforward.

  2. After Quote: Once the quote is accepted, we’ll visit your property to assess the site and soil, then send you a preliminary plan for wastewater disposal for consultation.

  3. Final Report: Once you've endorsed it, we’ll prepare the final report in 10-15 working days. You’ll need to provide your local Council with your wastewater report.
