BIGGERA CREEK FLOOD DETENTION BASIN STORMWATER PIPE REHABILITATION (SWP SL)

Project Description:

Abergeldie Watertech was engaged to reline a 1200mm diameter stormwater pipe running through the Biggera Creek Flood Detention Basin. The stormwater pipe protects hundreds of houses in the suburbs below, so ensuring the structural integrity of the pipe and of the dam wall was a major factor during the project planning and construction phase.

The technology chosen to renew this pipe was Abergeldie Watertech’s Spiral Wound Pipe Sliplining (SWP SL) process. This process is used to rehabilitate large diameter pipelines and involves a spiral wound pipe being formed in situ within the host pipe at a slightly smaller diameter. This technology was used to ensure structural integrity and was chosen because of the size of the host pipe.

The finished liner was 80m in length with a finished internal diameter of 1,060mm. A total of 7,830 litres of grout wasw used on the project to secure the pipe in place.
