What is a service line in relation to water distribution?

A service line is defined as the pipe that connects the water main, which is part of the public water distribution system, to a customer's premises. This line is crucial as it facilitates the delivery of potable water directly from the municipal supply to homes or businesses. The service line typically runs underground and may include water meters, which help in measuring the amount of water consumed by the household or establishment.

Understanding the role of the service line is essential for maintaining water quality and ensuring that the distribution system functions efficiently. It is also a focus for service interruptions or issues pertaining to water quality, as any problems in the service line can directly affect the customer’s water supply. Other choices presented pertain to different aspects of water distribution but do not define what a service line is specifically.
