Onsite effluent disposal assessments to determine site suitability for sewage and wastewater systems.
Onsite Effluent Disposal Assessment
Our Focus
Hunter Geotechnical Services conducts onsite effluent disposal assessments to determine site suitability for sewage and wastewater systems, in line with AS/NZS 1547 standards.
Onsite effluent disposal assessments are essential for determining the suitability of a site for the safe and effective disposal of sewage and other forms of wastewater. These assessments ensure that the chosen effluent disposal system is appropriate for the soil, hydrology, and topography of the site. At Hunter Geotechnical Services, we conduct thorough onsite effluent disposal assessments in accordance with AS/NZS 1547, ensuring that your effluent system complies with the relevant standards and environmental regulations.
Whether you are installing a new system or assessing an existing one, our team provides expert recommendations tailored to your site’s specific conditions, helping you choose the right system to safely manage effluent.
Key Onsite Effluent Disposal Assessment Services
- Site Investigation
We begin by collecting comprehensive data on the soil, groundwater, and topography of the site. This investigation helps us understand the site’s ability to absorb and treat effluent. Soil permeability, drainage patterns, and hydrology are all carefully assessed to determine whether the site is suitable for onsite effluent disposal. - System Evaluation
Our assessments also include an evaluation of the proposed effluent disposal system, whether it’s a sewage treatment system, septic tank, or aerated wastewater treatment system (AWTS). We assess factors such as the location, design, and environmental impact of the system to ensure it will function efficiently and meet regulatory requirements. - Environmental Impact Assessment
A crucial part of the assessment involves identifying any potential environmental impacts. This includes evaluating the risk of groundwater contamination, surface water pollution, and the potential for effluent overflow. Our goal is to recommend systems that minimise environmental harm while effectively treating effluent. - Compliance with AS/NZS 1547
All assessments are conducted in line with AS/NZS 1547, which provides the guidelines for the design, installation, and management of onsite effluent disposal systems. This ensures that your system is compliant with Australian and New Zealand standards, reducing the risk of future issues or non-compliance.
Types of Effluent Disposal Systems
- Sewage Treatment Systems: These systems treat household sewage to a level that is safe for land disposal.
- Septic Tanks: A cost-effective system for treating sewage and wastewater in areas without access to a centralised sewer network.
- Aerated Wastewater Treatment Systems (AWTS): These systems provide more advanced treatment of effluent, using mechanical aeration to enhance the treatment process.
- Advanced Secondary Treatment Systems (STS): These systems provide high-level treatment, suitable for areas where stringent environmental protections are required.
Benefits of Onsite Effluent Disposal Assessments
- Tailored Solutions: Our assessments provide site-specific recommendations, ensuring the chosen effluent system is appropriate for the soil and environmental conditions.
- Environmental Protection: We identify potential risks to groundwater and surface water, helping to protect the environment and public health.
- Regulatory Compliance: Our assessments are conducted in line with AS/NZS 1547, ensuring your system meets all necessary legal and environmental standards.
- Cost-Effective Planning: By determining the most suitable system early in the project, you can avoid costly changes or compliance issues later on.

Frequently Asked Questions
1. What is an onsite effluent disposal assessment?
An onsite effluent disposal assessment evaluates whether a site is suitable for the safe disposal of sewage and wastewater. It helps determine the best system for treating and managing effluent based on soil, water, and environmental conditions.
2. What types of systems are assessed?
We assess various effluent disposal systems, including sewage treatment systems, septic tanks, aerated wastewater treatment systems (AWTS), and advanced secondary treatment systems (STS).
3. Why is compliance with AS/NZS 1547 important?
Compliance with AS/NZS 1547 ensures that the effluent disposal system is designed and installed according to Australian and New Zealand standards, reducing the risk of system failure and environmental harm.
4. Can an effluent disposal system impact the environment?
Yes, improper effluent disposal can lead to groundwater contamination, surface water pollution, and other environmental issues. Our assessments help identify and mitigate these risks by recommending appropriate systems and designs.
