What does a service line specifically connect to in a water distribution system?

In a water distribution system, a service line is the pipeline that directly connects the water main to a building or property, such as a residential water supply. This line is crucial because it delivers potable water from the municipal system directly into homes or businesses. It typically ends at a meter where consumption is measured.

This connection is essential for providing residents with access to treated water for drinking, cooking, and sanitation needs. Each residential property requires its own service line to ensure that water can be supplied efficiently and safely to individual households.

The other options point to different components of the water system. The water treatment facility refers to the location where raw water is treated to make it safe for consumption, while the sewer system handles wastewater, and another water main would typically refer to the larger pipelines that transport water between different areas, not directly to individual properties.
