Drinking Water Advisory (DWA) Notice
A yellow Drinking Water Advisory Notice door hanger informs residents of work that is being conducted on the water supply system in the area. It also indicates that as a precaution, the residents affected should boil any drinking water. The advisory also includes information and instructions about boiling water, what to expect, and includes contact information if you have questions.
Once all laboratory tests are complete, city staff will deliver a green DWA Lifted Notice to inform residents that the water is safe to drink, after citizens follow the outlined instructions.
Keeping our Water Supply Safe
When the City of Yorkton is conducting any repairs or completing a planned project on the water supply system, it is possible for the system to become contaminated by its surroundings such as soil or other potential contaminants.
The following steps are always taken to ensure water safety:
- The water supply is shut off in the affected area
- The affected parts of the water supply system are depressurized and isolated using valves that prevent water from moving through the water supply system. However, during this work, it is possible for the system to become contaminated by its surroundings such as soil or other potential contaminants.
- When the work or repair is completed, the system is re-pressurized and completely flushed past the point of construction and out through the hydrant.
- City staff then collect chlorine and bacteriological samples. These water sample are drawn into sterile containers and delivered to an accredited laboratory where water quality testing occurs.
- The lab provides the results back to the City to confirm the work meets safe drinking water requirements. It can take up to a minimum of 72 hours to receive the results.
- At any point should there be a positive bacteriological result, the affected area will be re-flushed, re-sampled and re-tested.
