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 align with the introduction of a new protozoa barrier this year. This upgrade, which includes the installation of ultraviolet (UV) disinfection, is essential for enhancing the safety and compliance of Luggate’s drinking water supply.

Currently, Luggate’s drinking water undergoes chlorine treatment to effectively guard against bacterial contamination. Testing occurs regularly at various stages, including the source and post-treatment, ensuring quality throughout the distribution system. The council’s commitment to these enhancements has been in the planning stages for several months and is part of a broader initiative to improve water treatment across the district.

Investment in Infrastructure and Community Health

The introduction of the UV filtration plant is crucial for meeting national drinking water guidelines, as the existing Luggate scheme lacks the necessary protozoa barriers. According to Tony Avery, the council’s general manager for property and infrastructure, “The new treatment plant will ensure drinking water in Luggate remains safe and achieves compliance.” He also noted that new boreholes will help meet the growing community’s water needs.

Further developments include a long-term reservoir site near Wānaka Airport, which will significantly increase storage capacity as part of ongoing investments in the region. The council currently provides a reticulated water supply to over 17,000 properties across the district, supported by twelve water treatment plants and managed through 680 kilometers of pipeline.

Timeline and Expected Disruptions

The UV disinfection system is anticipated to be operational by Christmas this year, with all associated work expected to be completed by February 2026. Residents should be prepared for some disruptions in Luggate during the construction phase. These will include temporary traffic management measures, the movement of construction machinery, and increased noise and vibrations in the vicinity.

Beginning on September 1, 2023, the northbound lane on Church Street will be closed for approximately four weeks. Crews will excavate and trench to install new water supply pipes in the area. Access for residents on Church Street near State Highway 6 will be maintained, while a detour will be put in place for other northbound traffic via Shortcut Road.

The council’s proactive approach to upgrading the Luggate water plant demonstrates its commitment to ensuring safe drinking water for its residents while adapting to the needs of a growing community.
