Aerated wastewater treatment systems (AWTS) increase the level of treatment of the effluent by aeration and disinfection, so it is suitable for irrigation onto lawns or gardens.
It is important to remember that:
Although effluent produce is of a higher quality than septic tank effluent, most systems do not significantly reduce nutrient levels. Therefore an appropriately designed and maintained effluent disposal site is necessary.
AWTS must be operated continuously; power to the system must not be turned off. If AWTS are used at irregular intervals the system might need to be serviced before use.
Servicing is required every 3-4 months by a Council approved service provider. This cost must be considered when choosing this system.
