WAITAKI, New Zealand - The Waitaki District Council in New Zealand has upgraded its Oamaru Water Treatment Plant to increase plant capacity by 25%.

The plant currently supplies water to 14,400 residents of Oamaru, Weston, Enfield and Kakanui, with plans to connect more than 1,000 new residents in the coming years.

The plant now uses ZeeWeed 1000 R-1 membrane technology from GE, which is hoped to increase the lifespan of membranes by 30%, from seven years to 10 years.

GE said it would also save an estimated NZ$300,000 in purchase costs when compared with “like for like” replacement as well as NZ$100,000 annually in depreciation and operating costs.

The upgrade is part of a broader commitment by the council to provide high-quality drinking water to the growing local population.

Waitaki District Mayor Gary Kircher officially re-opened the plant and said: “It is critical that we have a reliable solution to meet our growing needs for years to come, and I’m confident that we have found that with this advanced technology.”
