Romsey's Water Filtration Plant to receive major upgrade

Construction has started this month to upgrade the Romsey Water Filtration Plant (WFP), with Greater Western Water (GWW) investing $27.8 million in a major project to improve local water supply and security.

The upgraded plant will bring many community benefits including increased capacity, boosted disinfection, advanced treatment processes, and better energy efficiency.

The upgrade will switch the drinking water disinfection process from chloramination to chlorination, which means Romsey residents will enjoy consistent tasting tap water all year round.

The installation of a brand-new UV disinfection system will provide added protection as part of the treatment process for Romsey’s drinking water.

GWW’s General Manager of Growth & Infrastructure, Ian Burton, said the upgrade is essential to future proof the region’s water supply.

"This project is a valuable investment in the Romsey community, ensuring a reliable water supply for years to come."

"The upgraded plant will be capable of treating up to 4.6 million litres of water per day, a significant increase from its current 2.65 million litre capacity, allowing us to meet growing demand while maintaining safe, high quality drinking water," he said.

The upgrade is expected to be completed in 2026

The upgrade won't change Romsey's water sources, which will continue to be supplied from multiple locations including Kerrie Reservoir, Wright Reservoir, local bores, Rosslynne Reservoir and the Melbourne supply system.

Greater Western Water has partnered with Victorian based Laurie Curran Water to deliver the project, which is expected to be completed in late 2026.
