You asked us why we can't use other types of water disinfection - here are the answers

Updated: May 23, 2019



Q: Why don’t we use in-home UV treatment instead?

A: Whatever disinfection method Government decides on, it will need to be applied at the water intake sites rather than individual households. This is because it’s important the system is centrally operated and maintained to ensure it is safe and reliable. Only disinfection, both of the water as it enters the network and the pipes, can achieve a safe and reliable public water supply. Pipe disinfection can only be achieved using small doses of chlorine.


Q: Why don’t we just boil our water instead?

A: While boiling water can make water safe to drink, only disinfection can achieve a safe and reliable public water supply. There are a number of reasons for this, including the fact that waterborne diseases can occur not only from drinking contaminated water, but also from other uses including bathing, brushing teeth, and washing salad vegetables.


Q: Why don’t we just keep using the community water stations?

A: Whatever disinfection method Government decides on, it will need to be applied at the water intake sites rather than at the water stations. This is because it’s important the system is centrally operated and maintained to ensure it is safe and reliable. Unfortunately the community water stations have not been reliable.
