What does PWS stand for in the context of water systems?

In the context of water systems, PWS stands for Public Water System. This term refers to a water supply system that provides water for human consumption through pipes or other constructed conveyance. It typically serves a population of at least 25 people or has a minimum of 15 service connections. Public Water Systems are regulated by government entities to ensure that the water quality meets safety standards established by the Environmental Protection Agency (EPA) or local authorities.

Understanding that a Public Water System is designed to serve the community and provide access to safe drinking water helps highlight its importance in public health. Unlike private systems, which may serve individual homes or small groups and are usually not subject to the same regulatory oversight, PWSs carry the responsibility of ensuring safe, clean water for larger populations. This distinction is crucial for utilities maintenance workers who must tailor their maintenance and operational practices to comply with regulations governing public systems and safeguard community health.
