According to the Safe Drinking Water Act, where does the responsibility of delivering potable water extend to?

The responsibility of delivering potable water extends to the consumer's tap inside the home as outlined by the Safe Drinking Water Act. This reflects the principle that the health and safety of drinking water is a comprehensive process that includes not just the treatment and delivery of water within the water supply system, but also the final point of use – the consumer's tap.

This regulation emphasizes that utilities are responsible for ensuring that the water quality remains safe and meets regulatory standards throughout the entire distribution system, right up to the point where the consumer accesses the water. Therefore, it is not sufficient merely to treat the water at the plant or maintain specific infrastructure elements like hydrants or pump stations; utilities must also consider any potential contamination risks that could occur in the distribution lines leading to the consumer’s tap.

This holistic view ensures that consumers receive safe drinking water, thereby upholding public health standards established by the Safe Drinking Water Act.
