SMART WATER RECYCLING
Safe On-Site Wastewater Treatment
When wastewater isn’t managed properly, it can lead to contamination, health risks, costly repairs, and long-term environmental damage. An Aerated Wastewater Treatment System (AWTS) offers a safe and efficient way to treat household wastewater before dispersing it into a designated land application area, making it ideal for homes, rural properties, and businesses without access to mains sewer services.
At VR Marsden Plumbing, we design, install, and maintain AWTS units across Coffs Harbour and surrounding areas. Our team provides reliable, compliant wastewater solutions that meet NSW Health and council requirements, helping you manage wastewater safely and efficiently.

System Care you can trust
Professional AWTS System Care
Your Aerated Wastewater Treatment System must be serviced every quarter to meet NSW Health and council requirements. At VR Marsden Plumbing, we carry out full quarterly inspections to ensure your AWTS is operating safely and efficiently. After each visit, we provide a detailed Quarterly Service Report, giving you the documentation needed to stay compliant year-round.
An AWTS partially treats household wastewater before it is dispersed into a designated land application area. This water cannot be used for irrigation, gardening, or any form of reuse.
Many customers compare AWTS units with traditional septic tanks when deciding which system is right for their home. Septic tanks are generally cheaper and simpler to install, requiring less maintenance and no electricity. However, this lower upfront cost comes with limitations — septic tanks rely only on anaerobic bacteria, while AWTS units use a combination of aerobic and anaerobic processes. This means an AWTS provides a higher level of treatment, making it a strong choice for properties needing more advanced wastewater management.
With our experienced team handling your installation and ongoing maintenance, your AWTS will continue performing reliably, safely, and in line with all regulatory requirements.
FAQ
Extra Helpful Information
What is an aerated wastewater treatment system?
An AWTS is a system that helps break down the wastewater from your home or business. It treats the water in a few stages, then sends it to a special disposal area on your property. Because it’s only partly treated, the water can’t be reused. AWTS units are great for places that aren’t connected to the mains sewer, and they need regular servicing to meet council and NSW Health rules.
How does an AWTS work?
An AWTS works by moving wastewater through several chambers that treat it step by step. Air is added to help good bacteria break down the waste, while solids settle at the bottom. Once the water has been partially treated, it’s sent to a special disposal area on your property. This water can’t be reused for gardens or anything else — it must go into the approved land application area.
What are the benefits of an AWTS over a septic tank?
A septic tank is cheaper and simpler, but it only gives your wastewater a basic level of treatment. An AWTS goes a step further by using two types of bacteria to clean the water more thoroughly. It does cost more to run and maintain, but the treatment quality is higher, which is why many properties choose an AWTS when they need a more advanced system.
