1. Why are we adding anything to our water?

The Fraser Health Authority mandated that a secondary disinfection be added to the City’s water system. The Fraser Health Authority has been closely monitoring the City to ensure that the drinking water is being treated by an acceptable secondary disinfection as a condition of our operating permit. This was as a result of the 2010 Boil Water Notice Report when the water utility was under private ownership.

2. Does the City have primary water disinfection?

Neighbouring jurisdictions’ water systems are different than White Rock’s as they require both primary and secondary disinfection and therefore different treatment processes are more appropriate. As White Rock has a groundwater source (confined aquifer/deep wells) it only requires secondary disinfection. The deep wells provide a natural first layer of protection against microbial contamination.

3. What is secondary disinfectant?

Secondary disinfection provides long-lasting water treatment as the water moves through pipes to consumers. It also maintains water quality by killing potentially harmful organisms. Both monochloramine and chlorine are secondary disinfectants.
