Helping Lincoln University Manage Effluent Sustainably
At their South Island Dairy Demonstration Centre, Lincoln University is focused on sustainable success. They research, implement and evaluate the best technologies and practises to protect their people and the environment – both now and into the future.
Nairn Electrical were contracted by Waterforce to design and deliver a complete electrical dairy effluent solution to suit the pumping and separation system Waterforce had designed for Lincoln University’s Demonstration Dairy Farm requirements.
The system requires raw effluent to be collected in a holding tank, pumped through a separator system, and once separated, pumped to a remote storage pond.
The storage pond contains a separate effluent stirrer and an irrigation pump to deliver the separated effluent water to existing pivot irrigation. The irrigation pump is controlled by our Nairn Electrical irrigation controller in conjunction with a Danfoss VSD adapted to suit the effluent application.
Keith Cameron, Emeritus Professor at Lincoln University’s Depart of Soil & Physical Sciences, was delighted with the performance of the Nairn Electrical team.
“Nairn Electrical provided highly professional electrical expertise enabling the new effluent system to be installed at Lincoln University Dairy Farm. High quality reliable electrical work was needed to power and control all the pumps, stirrers, separator, actuators and pond sensors in the new effluent management system at LUDF; Nairn Electrical provided this ‘on-time and within budget’. The attention to detail, safety and the neat and tidy finish is a credit to your team.”
