Launceston Sewerage Improvement Project - Stage 2


The Launceston Sewerage Improvement Project (LSIP) has reached another important milestone with the TasWater Board endorsing the recommendation for a new Northern Sewage Treatment Plant (STP) at Ti Tree Bend and the decommissioning of six greater Launceston STPs.

The decision - at the Board's 3 December meeting 2014 - followed a significant level of community consultation on the four options under investigation to address problems with Launceston's ageing sewage treatment infrastructure.

Approval was also given at the meeting for the commencement of work on preliminary designs, constructability assessments and detailed cost estimates.

Options under consideration by TasWater included:

- Option 1 - upgrading all seven STPs in the greater Launceston area (including those at Ti Tree Bend, Hoblers Bridge, Legana, Riverside, Newnham, Prospect Vale and Norwood);

- Option 2 - construction of a new Southern STP with part re-use and a new Newnham STP;

- Option 3 - construction of a new Northern STP at Ti Tree Bend;

- Option 4 - construction of a new Killafaddy STP and a new Newnham STP.

The endorsed recommendation will see the construction of a new Northern STP at Ti Tree Bend to cater for sewage from Hoblers Bridge, Legana, Riverside, Newnham, Prospect Vale, Norwood and the separate sewerage sub-catchments within the Ti Tree Bend catchment.

Future upgrades are planned for the existing Ti Tree Bend STP, which will continue to treat combined drainage flows.

The six STPs being decommissioned will continue to act as pump stations and buffer storages while the one centralised STP at Ti Tree Bend will provide treatment.

Of the four options considered by TasWater, Option 3 represents the best value for money in terms of lowest capital cost for staged implementation, lowest overall capital cost and lowest operational cost.

It was also the option that attracted the strongest level of support during a community engagement program in late 2014.
