Blackstone Rd Sewage Pump Station

In November 2013 a landslide at 156 and 158 Blackstone Road, Blackstone Heights, Prospect destroyed a section of sewer pipeline that serviced 15 properties, from 156 to 176 Blackstone Road, Launceston.

In order to maintain sewer services to the affected properties immediately after the landslide, a temporary portable petrol driven pump was set up in a manhole at 160 Blackstone Road. Temporary above ground sewer connections were installed at 156 and 158 Blackstone Road.

Reinstatement of the existing services was not and is not possible as the slip site remains unstable. The topography is steep and rocky, with a history of landslides, while several lots also have areas of fill and spoil, which may be highly susceptible to further erosion and future landslip.

Due to these constraints, a new sewage pump station (SPS) to transfer the flow around the slip has been identified as the most feasible option.

The proposed pump station would lift the sewage to an extension of the existing gravity sewer located on the eastern side of Blackstone Road. Taswater as part of this project has purchased the vacant block at 160 Blackstone Road to allow the construction of the new SPS.

The goals of this project are:

  • To provide a reliable sewage service for TasWater (TW) customers
  • Provide a safe working environment for TW contractors and employees
  • Protect the highly environmentally sensitive Trevallyn Lake receiving water.

Tenders have currently been called for this project.
