What is a Noncommunity Water System (NCWS)?

A Noncommunity Water System (NCWS) refers to a public water system that provides water to the public intermittently rather than on a year-round basis. This type of system typically serves transient populations, such as at campgrounds, schools, or restaurants, where water is supplied but does not serve the same individuals continuously throughout the year.

Understanding the definition of NCWS is crucial for water operators as it helps in regulatory compliance and ensures that water quality standards are met for public health protection. Every water system must adhere to specific monitoring and reporting requirements, even if it does not serve the same clientele consistently. This framework is established to maintain safe drinking water quality and to provide necessary protections regardless of the duration of usage by consumers.
