Longford Sewerage Treatment Plant upgrade

The Longford STP Upgrade project seeks to improve compliance per TasWater's commitment to EPA via the Effluent Compliance Plan (ECP).

The ECP anticipates that full improved compliance will be achieved by June 2021. The TasWater Board approved a business case in June 2017 and a budget uplift to proceed with an amended scope of works April 2019. The TasWater Major Projects Team began an extensive procurement process in July 2017 including an early contractor involvement and competitive tender stage, culminating in the award of a TasWater Design and Construct Contract (AS4902) to AquatecMaxcon in May 2019.

The Design phase of the project has been completed on-schedule with the new plant expected to be in operation June 2021.

An innovative new Nereda process is being employed for the first time in Tasmania to treat sewerage. This system is quite robust and has been very successful in other states in Australia and overseas countries.

The contract is to be managed as a pre-existing TasWater Contract (PTC) with the support of the CDO.

The expected project benefits include:

  • Reduced odour impacts on neighbouring properties
  • Improved water quality (ie reduced risk of algal blooms) in Back Creek, South Esk River and Lake Trevallyn, protecting recreational amenity and
  • Reduced drinking water quality risk for water sourced from Lake Trevallyn near the end of the South Esk River.
