Beaudesert Water Supply Upgrade

We're connecting Beaudesert to the SEQ Water Grid and building a new water treatment plant to supply the growing Scenic Rim and South Logan regions.

The Beaudesert Water Supply Upgrade (BWSU) will provide a long-term water supply solution for the Scenic Rim, supporting continued population and economic growth.

Home What We're Doing Beaudesert Water Supply Upgrade

Connecting Beaudesert will improve long term water security for the Scenic Rim and make it easier to move water into the region when needed.

The Beaudesert Water Supply Upgrade includes three major elements:

  • Immediate improvements to the Beaudesert Water Treatment Plant, including construction of two new storage reservoirs with treated drinking water storage of 5.1 million litres. Work was completed in 2020.
  • The South West Pipeline which is a 24 kilometre pipeline connecting Beaudesert to the SEQ Water Grid, and a three kilometre pipeline to connect the Logan supply network off the corner of Bushland Road and Teviot Road to the Wyaralong Transfer Station. The Wyaralong Transfer Station helps to ensure water quality standards are maintained before the water is pumped 24 kilometres south to Beaudesert. Once completed, expected in mid-2024, this pipeline will be the most significant addition to the SEQ Water Grid since 2012 and will ensure a reliable long-term water supply for the community, by moving water into the region when needed.
  • Proposed construction of a new Water Treatment Plant that will draw water from Wyaralong Dam.

  • In preparation for connecting Beaudesert to the SEQ Water Grid in 2024, Seqwater changed the disinfection method of Beaudesert’s drinking water from chlorine to chloramine in February 2024. 

    As the South West Pipeline project nears completion, Beaudesert will soon be connected to the water grid to increase the resilience of the town’s future water supply. When connected, Beaudesert will be supplied with water from both the Logan River and the SEQ Water Grid.  

    In preparation, the local drinking water disinfection method – an essential step in the water treatment process – transitioned from being treated with chlorine to being treated with chloramine. This ensures that the local water supply will match the treated drinking water in the SEQ Water Grid. 

    Like chlorine, chloramine is a safe and effective disinfection product that has been used for many years to destroy bacteria and other harmful microorganisms that can be present in source water. Chloramine lasts longer in the water supply than chlorine, keeping the water safe as it travels through long pipelines, like those that make up the SEQ Water Grid.  

    South East Queensland has some of the highest quality drinking water in the world, thanks to our effective water treatment processes. Drinking water is cleaned and treated at our water treatment plants and constantly monitored throughout the network to the stringent standards as set by the Australian Drinking Water Quality Guidelines.

    Seqwater worked closely with Urban Utilities to communicate with local residents and businesses about this change. While most people didn't need to take any action ahead of the changeover, some groups may have needed to take steps to prepare.

    Home dialysis

    Home dialysis units are fitted with a filtration system that removes both chloramine and chlorine from the water supply. Queensland Health has advised home dialysis users should not need to take any action due to the change. Anyone with questions relating to their home dialysis unit is encouraged to speak with their home dialysis unit or nephrologist.

    Fish tanks, aquariums and ponds

    If you have a fish tank, aquarium or pond, the change in disinfection from chlorine to chloramine could affect your fish or other aquatic creatures.  Chloramine is a combination of chlorine and ammonia. Because the chlorine in chloramine takes longer to dissipate, you should not rely on aging water in buckets or running it through a filter in a separate tank before adding it to your fish tank or pond.  

    The best way to ensure the water is safe for your fish or aquatic animals is to use a dechlorinating agent.  Not every dechlorinating agent neutralises chloramine, some only neutralise chlorine, so check the label to make sure you are using the correct product. If you are not sure, ask the product supplier or consult your pet store or local aquarium for advice.  

    Pools and spas

    Pool and spa owners may need to adjust chlorine levels to achieve the right chlorine concentration. Continue to test your overall chlorine concentration as part of your usual maintenance routine and please contact your pool store if you need further advice.
