An $8 million water filter upgrade at Seqwater’s Landers Shute Water Treatment Plant improving water security for Sunshine Coast residents from June 2025. 

The filter refurbishment is part of a wider $24 million investment project to safeguard the lifespan of the existing primary water filters and strengthen water infrastructure resilience for the plant.  

The primary filters play a key role in providing safe drinking water by removing contaminants from raw water before it goes through further advanced stages of the water treatment and disinfection processes.  

The plant is supplied with raw water from the Baroon Pocket catchment and can treat up to 140 megalitres a day (equivalent to 56 Olympic-sized swimming pools). 

Seqwater Executive General Manager, Operations, Fiore Zulli, says the upgrade ensures water security for the Sunshine Coast and Brisbane.  

“We know the Sunshine Coast area is experiencing rapid population growth, urban expansion, and increasing economic activity,” Mr Zulli said. 

“To improve water supply and security for local communities, Seqwater is focussed on upgrades to the SEQ Water Grid from Brisbane to the Sunshine Coast. 

“The completion of this project significantly improves the plant’s performance without the need for major filter upgrades for at least another 15 years. Landers Shute will be a more resilient asset delivering continued reliability to customers across the Sunshine Coast and north Brisbane,” he said. 

The second $16 million stage of the upgrade focusses on constructing a new process to treat seasonal filter clogging algae from Lake Baroon. This project is currently out for tender with construction starting early 2026. 

Completion of the water filter upgrade took just under nine months with principal work undertaken by Freyssinet Australia. Mr Zulli acknowledges all the teams involved in project managing and delivering another significant project for the Sunshine Coast region.
