Why is backflow prevention essential for public health?

Backflow prevention is essential for public health primarily because it prevents contamination from reversed flows in the water supply system. When backflow occurs, it can allow polluted or contaminated water from sewage systems, industrial processes, or other sources to flow back into the clean water supply. This contaminated water can pose significant health risks to individuals and communities, leading to the spread of waterborne diseases and other health hazards.

By maintaining proper backflow prevention mechanisms, the integrity of the drinking water supply is protected, ensuring that the water remains safe for consumption and use. In addition to protecting public health, effective backflow prevention contributes to regulatory compliance and helps maintain trust in community water systems.
