How do I find Australian standards

Australian standards AS / NZS 1546.1 and AS 1546.3

With the publication of the Australian standard AS 1546.3: 2017 "On-Site domestic wastewater treatment units - Part 3: Secondary treatment systems", version AS 1546.3: 2008 was replaced. The current standard AS 1546.3: 2017 specifies requirements for the design, commissioning, performance and conformity testing of decentralized sewage treatment plants for the treatment of domestic wastewater. In addition, instructions for installation, operation and maintenance are given. The standard also specifies test procedures for systems with a treatment capacity of 1,200 - 5,000 l / d.

Following a run-in phase, the systems must be tested for at least 34 weeks under changing stress conditions. Each model in a series must be tested individually; theoretical approaches to calculating a series are not recognized. There are a total of 4 classes for the classification of a sewage treatment plant, for which the criteria for the discharge quality are specified in the standard.

In addition to testing the sewage treatment plants in accordance with AS 1546.3: 2017, the tanks must meet the requirements of the AS / NZS 1546.1: 2008 standard, “On-site domestic wastewater treatment units, Part 1: Septic tanks” for hydraulic design, material and stability .

PIA GmbH, as an ISO 17025 accredited laboratory, carries out all tests under the conditions required by the Australian standards. PIA GmbH cooperates with the Australian validation agency SAI Global, which issues the certifications for the Australian market after successful tests.

There are currently around 30 manufacturers of decentralized wastewater treatment plants in Australia. The government of South Australia demands that manufacturers have to have their systems tested according to the new Australian standard by the end of 2020, otherwise these systems can no longer be sold in South Australia.
