So far, 12 of 19 District Councils in the South Island have aerdisc® Directional Aerators either in operation, or in progress.
Just 26-months after the first aerdisc® installation for Central Otago District Council at their Cromwell WWTP, South Island local government projects have grown to 27 with many others pending.
4 of the 27 units were provided as part of the Nationwide Local Government Pilot Study; 6 others were provided for subsequent trials. 17 units were purchased outright.
