Compliance testing of on-site domestic wastewater Secondary Treatment Systems

 

The Arris state-of-the-art compliance testing facility at SA Water’s Hahndorf wastewater treatment plant in South Australia undertakes AS 1546.3:2017 compliance testing of on-site domestic wastewater treatment Secondary Treatment Systems (STSs) with design hydraulic treatment capacities of between 1,200 and 5,000 L/d. Compliance testing according to AS 1546.3:2017 comprises a 42 week long combined commissioning and testing period (minimum testing period 34 weeks) conducted under specified conditions in order to demonstrate the performance and reliability of STSs under normal ‘steady-state’ design operations and also challenge ‘stress testing’ conditions.

Applications are now open for limited spots available in 2022

The Hahndorf facility is located in climate zone 6, offering STS providers the capacity for cool, winter climate testing to verify low temperature performance as per AS 1546.3:2017. The facility has a 40 m long concrete bunker with nominal depth of 2.1 m which allows STS systems to be installed and backfilled with sand to simulate fully in-ground in situ operating conditions during testing. The facility has capacity to accommodate up to 10 domestic treatment units concurrently.

A limited number of positions are currently available for new systems to be installed for testing to commence during the first quarter of 2022. For those wishing to test their system beyond 2022, expressions of interest are being sought and applicants will be placed on a wait list for future testing rounds from 2023.
