In June 2015, TasWater signed a memorandum of understanding with the Tasmanian Government and the Macquarie Point Development Corporation, for a feasibility study into relocating the Macquarie Point Sewage Treatment Plant. This study required TasWater to identify an alternative location to treat existing sewage flows and to ensure the sewage management meets both community expectations and TasWater's licence requirements, issued by the Environment Protection Authority.

TasWater is proposing to divert flows from Macquarie Point to the Selfs Point Sewage Treatment Plant, which will be upgraded and expanded.

The existing outfall for the Selfs Point plant is off Blinking Billy Point in Sandy Bay, into the Lower Derwent. There is a second outfall off Selfs Point into the Middle Derwent Estuary, which is only used during emergencies or following rainfall events. Both outfalls have sufficient capacity for additional flows.

A new sewage pump station would be built near the current site of the Macquarie Point Sewage Treatment Plant, to transfer flows to Selfs Point via a new pipeline from Macquarie Point to Selfs Point.

TasWater's most likely pipeline route from Macquarie Point to Selfs Point largely follows the route of existing underground pipelines. From Macquarie Point it will run past the Cenotaph, across the Tasman Highway, along Lower Domain Road and under the Cornelian Bay Sportsground.

The project will only proceed subject to funding. The final cost is yet to be determined and will be based on further investigations, community consultation, design and tendering, but is estimated to be a minimum of $130 million.

You can learn more about this proposal by reading our FAQs and taking a look at some images.
