Notice of Water Main Cleaning and Flushing
Boil Water Order still in effect until further notice.
Kemp Lake Waterworks is undertaking precautionary measures in response to the recent Boil Water Notice issued by Vancouver Island Health Authority.
We will be flushing and sanitizing the entire water system including all mains, hydrants and reservoirs.
What this process involves:
Flushing the entire system – this is to ensure minimal turbidity of the water prior to cleaning activities.
Super chlorinating the entire system – this is done by way of “shocking”, introducing a heavy concentration of chlorine at several times the normal percentage into the reservoirs and the service mains.
Standing time of super chlorinated water – in order to ensure effective contact time (standing time) of the chlorine within the system, it must remain for a minimum of 3 hours with as little water movement as possible.
Flushing of super chlorinated water – upon completion of the standing time in the system the entire system will need to be completely flushed of the high chlorine concentration and return the system to normal chlorination levels.
Timeline: As we need to ensure as little water movement as possible this work will be done between 11 p.m. on Saturday, 23 July, and 5 a.m. on Sunday, 24 July
Any water used during this period of time will have a heavy concentration of chlorine in it and should not be used for drinking, cooking, showering, laundry, watering for pets or livestock, if at all possible no water use during the flushing and cleaning is preferred.What you can expect as a consumer
- Although we will be completely flushing the system there will likely be a small residual amount of chlorine in the water from the water meter into your residence.
- Consumers should run their water for minimum 2 minutes to ensure super chlorinated water has been expelled from the meter into the property as we cannot enter private property to flush lines from the meter into your residence.
- During the flushing and cleaning operation consumers can expect elevated levels of turbidity (cloudy water), periods of low water pressure, and a heavy odour of chlorine (bleach like odour).
- The heavy chlorine dosage is not dangerous but is not acceptable for consumption by people, pets or livestock.
Please only essential water usage during the day Sunday because it will take most of the day to refill both of our reservoirs.
We appreciate your understanding and cooperation. Every effort will be made to complete the project as per the timelines noted above.
