Queenstown Lakes Council Accelerates Luggate Water Plant Upgrades

The Queenstown Lakes District Council has expedited upgrades to the Luggate water treatment plant, moving the completion date forward from 2028 to 2023. This decision aligns with the introduction of a new protozoa barrier, specifically ultraviolet (UV) disinfection, which is scheduled to be operational by Christmas this year. The upgrades aim to enhance water safety and compliance with national drinking water standards.

Currently, Luggate’s drinking water undergoes chlorine treatment, which effectively combats bacterial contamination. Regular testing is conducted at the source, after treatment, and throughout the distribution system to ensure safety. The council has prioritized this investment as part of a broader initiative to future-proof water capacity and install protozoa barriers across all its supplies.

Tony Avery, the council’s general manager for property and infrastructure, emphasized the significance of the new treatment plant. “The new treatment plant will ensure drinking water in Luggate remains safe and achieves compliance. New bores will help provide enough water to meet the needs of this growing community,” Avery stated.

In addition to the upgrades, the project includes the development of a long-term reservoir site near Wānaka Airport. This reservoir is expected to significantly increase storage capacity, supporting future investments in the region. The council manages a reticulated water supply for over 17,000 properties across the district, utilizing 12 water treatment plants and maintaining a network of 680 kilometers of pipes, serviced by 34 pump stations.

The anticipated protozoa barrier is crucial for meeting the treatment requirements outlined in national guidelines. Completion of all remaining work is projected for February 2026. Residents in the Luggate area should prepare for temporary disruptions during the construction phase, which may include traffic management, noise, and vibrations.

Beginning on September 1, 2023, the northbound lane on Church Street will close for approximately four weeks due to excavation and trenching for new water supply pipes. Access for residents living near State Highway 6 will be maintained, while a detour for northbound traffic will be established via Shortcut Road.

As the project progresses, the council remains committed to ensuring that the drinking water in Luggate remains safe and compliant with health standards, catering to the growing needs of the community.
