What is an Annual Environmental Review (AER)?
TasWater owns and operates 110 sewage treatment plants (STPs). 33 Level 1 STPs are regulated by local councils and 77 Level 2 STPs are regulated by the EPA.
Annual performance and environmental management reporting in the form of an Annual Environmental Review (AER) is required under Permit and Environment Protection Notices (EPNs) for each Level 2 Sewage Treatment Plant. An AER allows TasWater to demonstrate they are monitoring the performance of the STPs, reviewing compliance, and exploring opportunities to improve environmental outcomes.
TasWater has made these documents available to the public to ensure disclosure of STP performance and management information is clear and accurate. AERs are submitted annually to EPA Tasmania.
