An aerobic treatment unit (ATU) is a packaged wastewater treatment system used at some homes that are not connected to sewer, or where treated wastewater management is required. It may include an underground round or rectangular tank, access lids, an air blower, pumps, alarms and irrigation or disposal equipment.
These systems use air and biological treatment to break down wastewater before controlled disposal. When part of that process is interrupted, the visible sign may be an alarm, odour, poor irrigation, a leak or a change in how the system operates. Those signs do not identify the cause on their own, but they are useful information to pass on when seeking aerobic treatment unit repairs and servicing.
Common reasons for ATU repairs and servicing
ATU repairs may be needed when equipment or system operation is not working as expected. Report what you have noticed rather than trying to diagnose the fault yourself. Details such as whether the issue is constant or intermittent can help a plumbing business understand the situation.
Alarm faults or changes at the controller
Air blower or pump failure
Blocked filters
Odour around the unit or disposal area
Poor irrigation performance
High sludge levels
Power interruptions
Missed service intervals
What servicing can involve
Aerobic treatment unit servicing focuses on the ongoing care of the treatment system and its associated equipment. For repair and maintenance work, routine servicing and dosing may be required in many instances by the Department of Health and the manufacturer. The manufacturer’s recommendations and guidelines are an important reference for the particular unit.
AWTS servicing is a commonly used search term for this work. Whether you are following a routine service schedule or responding to a change in the system, the unit’s records and labels can help keep the conversation focused on the equipment at the property.
Prepare useful information before contacting a plumbing business
A short, clear description can make it easier to explain what is happening at the home. Gather what is readily available and describe the situation in plain language.
Note when the fault began and whether it is intermittent or constant.
Take photos of the alarm, controller, data plate, leak, surrounding pipework or affected area.
Locate service records, warranty information and details of recent repairs if you have them.
Provide the property address, contact person and practical access instructions.
Explain any urgency or safety concerns, whether the area is occupied, and whether sewage or stormwater is backing up.
Identify affected fixtures and any inspection openings or pit locations you know about.
Photos or short videos can be useful where they show the issue, surrounding area or equipment labels. They are not a substitute for a plumbing business considering the system at the property.
ATUs within the home sewer system
An ATU sits within the broader sewer arrangements for a property. Sewer work can involve pipework, pits, tanks, drains and disposal pathways, as well as repairs, cleaning, replacement and maintenance planning. An issue that appears around an ATU may involve the unit itself, its associated equipment or connected wastewater infrastructure; the available information helps distinguish the relevant starting point.
If your need is not repair or routine servicing, related residential sewer work may include ATU installations, greywater system work, septic tank work, sewer conversions, sewer installations and sewer and storm water pipe relining.
Products and names you may encounter
Equipment labels, records and discussions about wastewater systems may refer to product systems, manufacturers or supply channels. Examples customers may encounter include Biomax, Ecomax, Aquarius Taylex Fujiclean, Polymaster and Reece. Other names associated with this service include Iplex, Vinidex, Everhard, Reln and ACO.
These names can help identify existing equipment or related pipework and drainage products. They do not indicate which products a plumbing business uses or services, so it is helpful to share the exact name and details shown on the equipment at the property.

Frequently asked questions
What is an aerobic treatment unit?
An ATU is a packaged wastewater treatment system. It commonly has a tank, access lids, air blower, pumps, alarms and irrigation or disposal equipment, and uses air and biological treatment before controlled disposal.
What information helps with ATU repairs?
Useful details include the make, model and serial number where available, photos of alarms or equipment labels, when the issue started, whether it is intermittent, and any previous service or repair records.
What can cause an ATU alarm or odour?
Alarm faults, blower or pump failure, blocked filters, power interruptions and missed service intervals are among the issues associated with ATUs. An alarm or odour alone does not confirm the cause.
Why are service records useful?
Service records, warranty information and details of recent repairs can provide context about the existing unit when discussing aerobic treatment unit servicing or repairs.
Is AWTS servicing the same as ATU servicing?
AWTS servicing is a search term used for servicing aerobic wastewater treatment systems. An ATU is a packaged wastewater treatment system, so the equipment details at your property help clarify the work required.
What if sewage or stormwater is backing up?
Tell the plumbing business that this is occurring, along with which fixtures are affected, whether the issue is internal or external, and the location of any inspection openings or pits you know about.
Use Find a Master Plumber to choose a plumbing business for aerobic treatment unit repairs and servicing. Providing the unit’s label details, service history and a clear description of the concern can help start the conversation.
