Phase 1: Understanding the data

In April 2024, one of the agreed outcomes between the Environment Protection Authority (EPA) and Coliban Water regarding the new Operating Licence for the Kyneton Water Reclamation Plant (WRP) was that a range of water quality and river flow data would be made available to the public via our website.

We are working towards compliance with these licence conditions and installing instream monitoring devices.

The data from these devices will be published once the project to install them is complete.

In the meantime, we are publishing currently available flow and water quality data, in line with the agreed outcome.

There are some important things you should consider when reading this data:

  • Coliban Water is a highly regulated business, and our water quality and flow data for the Kyneton WRP is routinely supplied to the EPA for their information and review.
  • The new Operating Licence for the Kyneton WRP was underpinned by an extensive, evidence-based, environmental risk assessment (ERA), which was designed to protect the environment and human health, as well as being consistent with our Environment and Sustainability Policy Statement.
  • All routine water quality samples are collected and analysed by a laboratory accredited by the National Association of Testing Authorities, and all results are reviewed to assess the ongoing performance of the WRP. If any results are unusual, the cause is investigated, and the treatment process is adjusted accordingly.
  • While we review and respond to all results, you can get only get a true picture of overall water quality by looking at changes in quality trends over time.

February 2025 update:

During February 2025, no flow was recorded in the Campaspe River at the Kyneton gauging station. In addition, there were no treated water released from the Kyneton WRP to the Campaspe River during February 2025.

Low or no flow conditions also mean that there is insufficient water in the river for the instream water quality testing units to record accurate results.

Therefore, there is no water quality update for February 2025. The next monthly water quality update will occur when there has been sufficient flow in the river to record accurate results.

  • Volume and flow data

    The volume of treated water released from the Kyneton Water Reclamation Plant to the Campaspe River, as well as flow data for the Campaspe River, as measured at Gauging Station that is located in Kyneton.

  • Quality of river water

    The quality of river water, measured within the Campaspe River upstream and downstream of the Kyneton Water Reclamation Plant, for those weeks when the plant is releasing treated water to the river.

  • Instream monitoring of water quality

    In addition to laboratory-based results, there is also in-stream monitoring of river water quality, at two sites on the Campaspe River, one upstream and one downstream of the release point of the Kyneton Water Reclamation Plant.
