Sewer main pipe laying (DN250 PE sewer main) undertaken as part of the 3 Towns Sewerage Upgrade to bring sewer reticulation to residents in the area. The project involved the installation of 14, 679m of welded polvethelene sewer pipe ranging in size from 160mm to 400mm in diameter. Killard Excavation Pty Ltd has its own PE welders and performed both butt and fusion welds, debeading of line and CCTV footage of each joint prior to PE pipe being installed within the trench.
Pipe installed in roadways under traffic control and included installation of valves, scours, jetting points, flushing points, and permanent restoration.
Worked closely with the community as well as with the RAAF base where works were located. Also included separate contracts to construct pump stations at each town.
