In December 2025, Katunga’s drinking water supply was successfully connected to a new drinking water supply from the Numurkah Water Treatment Plant. This upgrade replaces the previous groundwater source and delivers improved water quality for the community.

What we delivered

  • A 7.5km pipeline delivering treated drinking water from Numurkah to Katunga
  • A new pump station and 1ML drinking water storage tank at the Numurkah Water Treatment Plant
  • Continued use of Katunga’s 200-kilolitre (kL) local storage tank
  • Works were completed between May and December 2025 with minimal disruption
  • Groundwater bores are to be decommissioned, while the Katunga site continues as a treated drinking water storage location

What this means for Katunga

The new Katunga water supply pipeline delivers a reliable long-term drinking water supply for customers through to 2060 and improves overall water quality. This project addresses feedback received from customers about the hardness of the previous groundwater supply and its impact on household appliances.

Note: Properties along the new pipeline will not be considered for water-by-agreement until mid-2026.

Frequently asked questions (FAQs)

When did Katunga switch to the new water supply?

Katunga customers began receiving treated drinking water through the new pipeline from the Numurkah Water Treatment Plant on Monday 15 December, 2025.

Why is this project necessary?

Katunga's previous water supply from underground bores met Australian Drinking Water Standards but had higher than average salinity and calcium levels. The new pipeline provides an improved, long-term drinking water supply for the Katunga community. The project also addresses feedback from customers about the hardness of the water supply and its impact on household appliances.

Will my water taste different?

From Monday 15 December, stored groundwater may take between 1-2 days to cycle through the system. Customers may notice a slight change in taste as stored water cycles through to the new supply from the Numurkah Water Treatment Plant.

Will the water pressure change?

No, water pressure will remain the same for both Katunga and Numurkah residents.

What will happen to the groundwater bores?

Groundwater bores will be decommissioned now what the new supply is connected and they are no longer in use. The Katunga site will continue to operate as a drinking water storage facility.

Can I connect to the new pipeline?

Properties along the pipeline will not be considered for water-by-agreement connections until mid-2026.
