Romsey Water Filtration Plant

Project overview

We’re investing $27.8 million to upgrade the Romsey Water Filtration Plant (WFP), located near Romsey and Glenfern roads.

This project will ensure a reliable supply of drinking water for the growing communities of Romsey, Monegeetta and Kerrie.

The upgrade will increase treatment capacity from 2.65 million litres per day to 4.6 million litres per day.

It will also Chlorination is the addition of chlorine to the water supply to destroy microorganisms.

An ultraviolet (UV) disinfection unit will also be installed to support the water treatment process.

The water sources to the plant will continue to be supplied from multiple locations, including Kerrie Reservoir, Wright Reservoir and local bores. The plant also receives additional supply during dry periods from Rosslynne Reservoir and the Melbourne supply system.

Construction is set to begin in January 2025, with completion expected in late 2026.

Why the project is needed

The Romsey WFP was first built in 1998 and is a vital community asset, supplying drinking water to customers in Romsey, Monegeetta and Kerrie.

Since the plant was first built, the area has experienced steady growth and the population is projected to grow 61% over the next 22 years, further increasing demand on the water supply.

While the Romsey WFP has served the community well for over two and half decades, to continue operating effectively, it needs a major upgrade.

The upgrade will mean the plant can continue to deliver safe and reliable drinking water to the community.

Benefits for Romsey and the surrounding region

The project benefits include:

• increased treatment capacity, from 2.65 million litres of water per day to 4.6 million litres per day
• ability to add future capacity of 2.3 million litres
• new technology and equipment with improved energy efficiency
• a change in the disinfection process aligning with metropolitan Melbourne's methods
• added protection of drinking water with the installation of a UV disinfection unit
• design features that will make it easier to accommodate future developments at the site.

Local impacts of the works

Here’s what you can expect:

• all construction at Romsey WFP to stay within the plant’s existing boundaries
• increased trucks, traffic, noise and dust near the site (all construction noise will comply with regulations)
• a slight difference in the taste and smell of your water once the new system is fully operational. The water quality will continue to meet all stringent drinking water guidelines.
• collaborating with local residents to minimise local impacts
• supporting our commitment to healing and caring for Country by ensuring environmental protection through necessary approvals.
