The existing wastewater treatment equipment for the campground at Glendhu Bay Holiday Park was not meeting discharge requirements. Because its adjacent lake — Lake Wanaka — is a source of drinking water for the local region, a new system was needed that could consistently meet treatment requirements, despite variable flows and a cold climate, to ensure the water was safe for both recreation and consumption.


The Queenstown Lakes District Council contracted Innoflow Technologies of Auckland to design and install a new wastewater treatment system for the park. Because of the need for an economical option that would reliably meet the given discharge limits while leaving only a small environmental footprint, Innoflow chose the Orenco® AdvanTex® AX-Max™ Treatment System, which is ideal for a variety of commercial applications with variable flows and waste strengths.
