Key Projects under the WNZP
  • Brisbane CBD Mains Renewals WP02: Charlotte Street, Creek Street, Coronation Drive, and Tank Street.
  • Upper Roma and Boomerang Streets – Brisbane CBD
  • Elizabeth Street – Brisbane CBD: 1 km stretch from George Street to Creek Street
  • Queen Street – Brisbane CBD: After more than 14 weeks of night shifts, the upgrade works on Queen Street included four network connections, 18 property connections, and over 500 meters of new pipeline, enhancing water supply to numerous businesses and residents. Despite challenges like storm clean-ups and coordinating with events like the FIFA Women’s World Cup, our team has demonstrated how important collaboration, and a one-team approach is.

Tanker Filling Stations: Helidon, Grantham, and Glenore Grove

Construction and commissioning of three new water filling stations for commercial and residential use in 2024. These stations are crucial for providing bulk water to key rural areas in Queensland, ensuring that farmers and residents have access to our most precious resource, especially during prolonged dry periods.

Esk Reservoir Project

Constructing a new 1.5ML water reservoir and pipeline to improve the reliability and resilience of the water supply network servicing the township. Additionally, we have completed a concrete footpath along Highland Street, transitioning into a winding gravel walk through woodlands.

Kilcoy Reservoir Upgrade

Using diver-assisted internal connection work, we’re minimising risks to water quality and maintaining full operational capacity during works at the Kilcoy Reservoir Upgrade.

Russell Terrace Pump Station Upgrade

Installation of a new Grundfos booster pump set, accumulator tanks, and an updated electrical system.
