He couldn’t be happier with the outcome. Thanks to his own design ideas and ADW Ltd’s expertise, David has a new effluent system that also eliminated the need to buy costly additional farm equipment. Technician Aidan Wright said Council guidelines and consenting processes demanded a new approach. The new effluent system consists of an existing modified, larger sand trap which stops heavy solids and rocks going through the sump system. Effluent is gravity fed from there to a new 100 cubic metre concrete sump supplied and installed by Able Precast, which delivers effluent straight to the field though a King Cobra irrigator from Numedic, meaning there is no build-up of solids in the main sump or the new 600 cubic metre storage bladder. If there is an issue with the first sump or conditions are not suitable for irrigation, liquids overflow to a 50 cubic metre greenwater sump and can then be transferred to the storage bladder if needed. For Dave Wright the system is an unqualified success. There’s no need to dig out solids or dealing with an effluent “soup” when it rains. What’s more, his Flexitanks bladder has a full, 10-year warranty. “So far it’s working pretty well,” Dave says. “I was worried about the increased wear and tear on the pump, but the increase in maintenance is grossly offset by not having to buy a bigger tractor and disposal equipment.” ADW Ltd specialises in the installation and repairs of cowsheds, water pumps and filtration.
