We have started controlled releases of recycled water from our Kyneton Water Reclamation Plant into the Campaspe River as of Thursday 4 June.
Releases to the Campaspe River are required to maintain storage levels in the onsite lagoons and are in accordance with flow and quality requirements of our EPA licence. The releases are weather dependent and will likely continue until November.
Under our EPA issued operating licence for the Kyneton Water Reclamation Plant, we make available to the public water quality and flow monitoring. The flow data, available one month in arrears and updated on the 21st of each month, can be viewed here.
Water treatment plant upgrades - Cohuna
- Cohuna
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.
