The installation of a new sewer rising main pipeline has marked the completion of TasWater’s upgrade works to the St John Street Sewage Pump Station in Launceston, and advanced environmental outcomes for Launceston’s Tamar Estuary.
Completion of this project marks a significant milestone for the Tamar Estuary River Health Action Plan (TERHAP) and is a key project to improve the health of kanamaluka/Tamar estuary by achieving the target of a 66 per cent reduction in combined sewage and stormwater overflow volumes in an average rainfall year.
Last week, the project team undertook major night works to connect the new pipeline into the existing pipe network.
TasWater Senior Project Manager, Amanda Allen, said the upgrade will increase the capacity of the drainage network to improve management of rain events.
“The upgrade increases pumping capacity at the St John Street Sewage Pump Station and the new 450mm diameter pipeline is able to transfer greater volumes of sewage and stormwater flows to the Ti Tree Bend Sewage Treatment Plant, keeping it out of the kanamaluka/Tamar estuary,” Ms Allen said.
“This project is one of many we will be delivering to improve the operation of Launceston’s combined system which manages the flow of both sewage and stormwater, especially during rain events.”
TERHAP is an initiative of the Tamar Estuary Management Taskforce and the Launceston City Deal, to improve the health of kanamaluka/Tamar estuary.
This project was jointly funded by the FederalAustralian and Tasmanian Governments, the City of Launceston and TasWater.
