The Oringi Freezing works wanted to overhaul their old effluent disposal system. Consultant Hamish Lowe from Glasson Potts Fowler called in ADL to help in the design. Hamish says they chose Dave from ADL to bring an independent approach to irrigation design. “I thought the design was very efficient because Dave doesn’t push one particular product. He is one of the few independent designers around.”
ADL chose center pivots with rotary boom irrigators to dispense the effluent on local farmland. Odour was controlled by nozzle choice, providing for decreased atomisation and therefore less odour. Keeping the nozzles low to the ground also helped. The tendency for effluent blockage had to be carefully considered in nozzle choice, and the Nelson sprinkler was chosen to meet all the demands of the project.
The effluent system has allowed Oringi Freezing Works to turn an area of gum trees into highly productive land without unnecessarily offending neighbours with odour and achieve what Hamish Lowe describes as an “efficient discharge of waste water.”
