Seqwater is enhancing water treatment processes at its Mount Crosby and North Pine water treatment plants.  

The enhanced treatment processes will deliver benefits to the Ipswich, Brisbane, Logan and Moreton Bay regions. Enhanced treatment will help stabilise water quality, including in summer when it needs to be more closely managed.  

The initiative is being undertaken in partnership between Urban Utilities, Unitywater, Logan Water and Seqwater. This initiative is due to be completed in the second half of 2025. It will make sure water continues to be delivered within Australian Drinking Water Guidelines. 

A key result will be strengthening the water quality by slightly increasing the pH level from about 7.8 to about 8.4 at the Mount Crosby and North Pine water treatment plants.  

Seqwater and water service providers will continue to test water in the water supply network to make sure it meets strict water quality guidelines. 

Most customers are unlikely to notice a change in their drinking water. 

Customers who treat their water or have specific water requirements may need to make adjustments to allow for the change in pH.
