Water Quality Advisory Issued:
March 14, 2025: The RRID is required to treat source water from Norns Creek according to the provincial 4-3-2-1 Objectives for drinking water. Maintaining a minimum UV dose is part of this requirement and one which the RRID takes seriously. However during mild conditions in our watershed, which periodically occur in the winter and spring, our source water quality becomes more challenging to treat as melting snow and/or heavy rain carry natural organic matter into the creek. Even though the water is still filtered to 0.03 microns, a non-filterable (dissolved) component in the water inhibits the UV transmittance through the water. This means that although we may still be operating the UV reactors, the UV dose falls below the regulated minimum criteria, and a Water Quality Advisory must be issued to protect the immunocompromised. This condition is usually short lived, as once the period of snow-melt or heavy rain subsides, the source water quality improves and the UV reactors are able to meet their dosage setpoints. During such periods, residents may sometimes notice a change in the water such as an amber colour. This represents the dissolved natural organic matter which has found its way into the creek and is not removable by our water treatment plant.

Water Quality Advisory is hereby lifted
April 29, 2025
Source water quality in Norns Creek has recently improved and appears stable. The UV system is reliably meeting its dosage target, and so the Water Quality Advisory is hereby lifted.
Freshet events are still expected later in the spring. The RRID will continue to monitor the system, and will provide further updates if and when required.
Water Quality Advisory Alert
March 14, 2025
Please be advised the RRID is issuing a Water Quality Advisory as of March 14th, 2025. Due to challenging spring conditions in our watershed, our UV reactors are unable to treat the filtered water to the required standards. A water quality advisory is the lowest-level notification. A water quality advisory is used in situations where the public health threat is modest, and actions can be taken to reduce the risks by ways other than requiring a boil water notice or do not use water notice. For information on Water Quality Advisories, please visit our website. For more information on why this issue typically occurs every spring, please also visit our website.
