Project overview

We're upgrading the Romsey Water Filtration Plant (WFP) so that we can continue providing a safe and reliable water supply as the community grows.

As part of the upgrade, we will be changing the way Romsey's water is treated and disinfected. The new process will be similar to Metropolitan Melbourne.

You may notice a slight change to the taste and smell of your water once the upgrades are complete. Your water remains safe to drink, and will meet all required drinking water standards.

Why are we upgrading the water filtration plant?

  • Respond to population growth

    We need to increase the amount of water produced at the filtration plant to meet growing demand. The upgraded plant will be able to treat up to 4.6 megalitres a day, significantly more than the current capacity of 2.65 megalitres a day.

  • The current plant is at the end of its life

    The existing water filtration plant is at the end of its operational life, which could lead to a decline in efficiency over time or other operational issues. The upgraded plant will help us manage water quality more effectively into the future.

  • Improve energy efficiency

    The upgraded filtration plant will use less energy than the current plant if both produced the same amount of water. This means it will be more efficient to operate.

  • Future-proof Romsey's water supply

    The upgrade has been planned with future upgrades in mind, to ensure we can provide clean drinking water to Romsey into the future.

How is Romsey's water disinfected?

Our water treatment process uses disinfection and filtration to produce safe drinking water. Find out more about how we treat our water.

Disinfection is an important part of the treatment process that destroys harmful pathogens in the water supply. Disinfection kills bacteria and viruses and provides ongoing protection as the water travels through our network.

As part of the upgrade, we will be changing the way Romsey's water is treated from chloramination to chlorination.

  • Chloramination

    Chloramination is the addition of ammonia to chlorine, which forms chloramines.

    Chloramines are effective at maintaining disinfection of the water supply over long networks.

    This is how Romsey's water is currently disinfected.

  • Chlorination

    Chlorination is the addition of chlorine to the water to destroy microorganisms.

    Once the upgrade is complete we will use chlorination to disinfect Romsey's water. This may result in a slight change to the taste and smell of your water.

  • Ultraviolet disinfection

    Ultraviolet (UV) disinfection treats water by using powerful ultraviolet light to neutralise harmful microorganisms.

    We will be installing UV disinfection as part of this upgrade to add an extra layer of protection for your water.
