In the context of water distribution supply, appurtenances refer to additional structures or components that are integral to the operation, maintenance, or functioning of a water distribution system. Valves are specifically considered appurtenances because they control the flow and pressure within the piping system, allowing operators to manage the distribution of water efficiently. They play a crucial role in regulating water supply, isolating sections of the system for maintenance, and preventing backflow.

Septic tanks, while important for wastewater management, are not part of the water distribution supply system itself. Storm drains are designed to carry precipitation and surface runoff, serving a different purpose related to stormwater management. Pipes are essential components of any distribution system but are classified as the primary infrastructure rather than appurtenances. The distinction lies in the fact that appurtenances enhance the system's functionality without being the main conduit for water transport.
