Multi-Barrier Approach
To ensure that our drinking water is safe we use the Multi-Barrier Approach, a system of procedures, processes and tools. The five parts of the Multi-Barrier Approach also help to protect our water supply into the future.
The Multi-Barrier Approach
Source Water Protection
Protecting lake or ground water used for drinking by taking action to reduce contamination threats. This approach can also reduce the amount of treatment required to clean the water.
Water Treatment Back-Up
Water treatment systems are designed with back-ups at all stages.
Secure Water Supply Network
Ensuring network integrity and chlorine levels are sufficient to protect the water from contaminant threats while it travels to the furthest downstream user.
Sampling & Monitoring Programs
Monitoring water quality at the source, the treatment plants, and throughout the town to ensure that the drinking water from all taps is safe.
Prepared Response Plan
Having a detailed plan for responding to water quality issues found despite all of the other barriers.
