Deephams Sewage Treatment Works

The upgrades at the Deephams Sewage Treatment Works involved the rebuilding of the sewage works’ inlet where sewage enters the works along with the construction of a new pumping station and screens to sieve out debris. Kilnbridge were contracted to provide a range of concrete cutting services as part of this project.

Two new storm tanks were built to hold excess sewage flows, and self-cleaning devices were fitted to existing storm tanks to ensure they emptied quicker and reduced odour. This remodelling work was undertaken while the plant remained live, continuing to treat 209,000m³ of sewage that arrives at Deephams each day.

Kilnbridge provided a range of concrete cutting services on this project to include the formation of openings to the top of tank walls, track sawing large sections of concrete slab and walls up to 400mm deep and stitch drilling, track sawing and diamond drilling to form various other openings.

By utilising wire sawing techniques, Kilnbridge reduced the height of the reinforced concrete walls of the live sewerage tanks into 1.8m sections for removal by crane.
