Urban Utilities is committed to excellence in water and sewerage services that enhance the liveability of our communities. The S1 main sewer was constructed a century ago and currently services more than 60 per cent of Brisbane. The main sewer pipe is up to 1.5m in diameter and lies 20m — the equivalent of eight storeys — beneath the ground.
The upgrade of the S1 main sewer has involved replacing or modifying existing maintenance holes and relining sections of the pipe along Kingsford Smith Drive (KSD).
KSD connects the suburb of Pinkenba to the Central Business District (CBD) at Breakfast Creek. It’s one of the busiest roads in Brisbane and carries an average of 70,000 vehicles per day. However, it’s not only vehicles that make their way along KSD. A critical Urban Utilities asset runs under the road – the S1 trunk sewer.
The S1 sewer is our largest sewer which runs from Coronation Drive to Luggage Point, through the Brisbane CBD. It transports over 60 per cent of Brisbane’s sewage, and protecting this critical asset is essential to the sustainable operation of the sewerage network.
Following relining works beneath KSD, vital maintenance commenced along Ann Street and Breakfast Creek Road to improve performance and ensure the stability of the network.
The section from James Street, Fortitude Valley, along Kingsford Smith Drive, Hamilton, to the pump station at Violet Street, Eagle Farm, needs essential rehabilitation and will be relined with a steel reinforced polyethylene pipe, using trenchless technology.
