Kangaroo Bay Rising Main Replacement

Kangaroo Bay sewerage pipe

TasWater has successfully completed the installation of a new underwater rising main across Kangaroo Bay in Bellerive, Hobart. This has reduced to risk of sewage spills into the bay and is a significant improvement for the area's environmental health.

Background to project

The Kangaroo Bay Rising Main takes sewage from the Wentworth Park pump station to the Rosny Sewerage Treatment Plant. It is 375 metres long, and travels between Cambridge Road in Bellerive and Seabird Avenue in Rosny. The rising main was constructed in 1967 and was confirmed to be at the end of its serviceable life, after which it was moved to the top of TasWater's priority list.

Project benefits

The benefits of this project are that a new pipeline will ensure a reliable sewerage system for the area, without the possibility of leakages and the associated environmental harm.

Options analysis and community engagement results

Having decided that the pipe was in need of replacement, TasWater undertook considerable planning before deciding on the best course of action. We considered three different routes for a new pipeline. The first option was to replace the existing pipe across the bay, while the other options involved going around Kangaroo Bay – one with a section of pipe behind the shops at Bellerive Quay, and the other along Cambridge Road. In order to assist us with our planning, we encouraged community input into the decision-making process through an online survey and a workshop.

The results made it clear that the best option was the ‘Across the Bay’ option, given it will have less impact on the community during construction, will limit disturbance to the local environment and is also the most cost effective.
