What is a Customer Water System?

A Customer Water System refers to all the piping and appurtenances used by a customer to convey water on their premises. This includes the infrastructure that carries water from the source (usually the utility company's main line) to the various fixtures within the customer's property, such as sinks, toilets, and irrigation systems. Understanding this definition is crucial for water operators as it highlights the transition from the public water supply to the private usage point.

The other options do not accurately describe a Customer Water System. For instance, while a service provided directly to customers without treatment may relate to how water is supplied, it does not encompass the entire system that conveys and utilizes that water. Describing a reservoir would pertain to storage rather than distribution and use at a customer level. Similarly, mentioning a filtration system relates specifically to the treatment of water rather than the infrastructure used for its delivery within a customer's premises.
