We are upgrading the Cohuna Water Treatment Plant as part of our Water Treatment and Storage Upgrade Program, a $40 million program of upgrades across our service region. 

Upgrades in Cohuna will include replacing the pump station, electrical upgrades, and improvements to water treatment processes at the plant.

Between July and September, work will be undertaken on the new powdered activated carbon dosing system, ultraviolet disinfection buildings, and wash water handling facility.

We'll be working on weekdays between 7am and 5.30pm with other low impact works on some Saturdays.  

No interruptions are planned as part of these works, but some customers may notice minor pressure fluctuations as testing is carried out. 

During the work there may be some noise and dust. Where possible, we'll reduce the dust by wetting down the site. You may also notice more trucks in the area using the plant entrance on Cohuna Island Road.
