What does the term "Customer Service Line" refer to?

The term "Customer Service Line" specifically refers to the line that runs from the water supply to the first point of use, typically at a customer's property. This line is crucial because it is the direct connection through which potable water is delivered to the customer. Understanding this definition helps clarify the role of the customer service line in the overall water distribution system, emphasizing its importance in ensuring that consumers have reliable access to clean water for consumption and other uses.

In contrast, the other definitions apply to different contexts within water or wastewater systems. The pipe connecting multiple buildings describes a different scenario, as it may refer to internal plumbing or interconnecting lines but does not specifically point to the customer’s service line. The main pipeline in a water distribution system refers to larger pipes that transport water over distances and supply multiple service lines, serving a broader function within the distribution network. The line used for sewage disposal pertains to wastewater management and does not relate to the delivery of potable water, thus distinguishing its purpose from that of the customer service line.
