If your property in the Shoalhaven LGA is not connected to sewer, an onsite wastewater management plan is required as part of the development process. Our reports set out how wastewater can be safely treated and disposed on your site sustainably.

​

We prepare wastewater assessments in the Shoalhaven region for:

• New dwellings and granny flats in unsewered areas.

• Upgrading, replacing, or relocating existing systems.

• Subdivisions or boundary adjustments.

• Commercial sites such as schools, restaurants, wineries, or tourism developments.​​

​

Each report includes:

• Site and soil evaluation.

• System design tailored to your property.

• A scaled site plan showing disposal areas and buffers.

• Recommendations for wastewater systems such as septic tanks, AWTS, greywater systems, composting toilets, or absorption beds; developed in consultation with our client and complying with the environmental constraints. 

​

For subdivision development projects, we also deliver land capability assessments. These are a critical early step that  confirms that a site can realistically support on-site wastewater management and helps avoid lot layouts that won’t meet council requirements later

​

We also provide wastewater testing and effluent sampling in the Shoalhaven. Testing measures system performance against key indicators including nitrogen, phosphorus, E. coli, and BOD, with results explained in plain language for homeowners, developers, and councils.

​​

With over 15 years’ experience in wastewater consulting, soil assessment, geology and compliance, our focus is on producing reports that are practical, technically accurate, and ready for Council submission.
