We manufacture a wide range of Septic Tanks and Collection Wells, to suit local Council requirements in different areas for different size dwellings. We are fully accredited with “NSW Department of Health” for our whole product range of septic tanks and collection wells. We are also fully licensed for Product Certification as a Quality Assured Product in line with the Australian StandardsMark.
All our septic tanks come standard with baffles, sealed lids, inlet and outlet fittings, caps and access lids. We generally try to work in with your drainage contractor or builder as to excavation timing so we can place the tank directly into the prepared hole, ready for backfilling. The hole should be at least 300mm wider than the tank diameter for ease of craning in. The base should be level and screeded with fine soil or sand, and the depth of the hole should allow for the tank to protrude 100mm higher than the surrounding finished ground level to stop surface water runoff entering the tank.
As our tanks are watertight they can float like concrete boats (after heavy rain) if the hole is not backfilled or the tank is not filled with water. Where ground water is a possibility and flotation may occur, we recommend pouring approximately 1-2m3 of concrete around the base of the tank before backfilling. When backfilling, no sharp rocks or stones should be used so no damage occurs to the tank wall or inlet and outlet pipework. Where pedestrian traffic could fall into the hole, safety barriers should be erected by the builder or contractor around the excavation area, the barrier will be repositioned (if taken down) by us for access/to place the tanks.
