What is a service line in relation to water distribution?

A service line in water distribution refers specifically to the pipe that connects the water main, which is a larger pipeline that carries water across the system, to the individual customer’s premises. This connection is crucial as it is the pathway through which water is delivered to homes and businesses from the municipal supply. Understanding this concept is essential because service lines play a key role in the infrastructure of water distribution, ensuring that safe and clean water reaches consumers.

The other options represent different components and concepts in water distribution. For instance, a main pipeline refers to the larger infrastructure that transports water more broadly, while a measurement of water pressure is a parameter used to gauge the system's performance, and a type of water filtration system relates to the treatment process of water rather than its delivery to end-users.
