What are the pipes that deliver large quantities of water to a town called?

The pipes that deliver large quantities of water to a town are referred to as primary feeders. These pipes play a crucial role in the water distribution system by transporting substantial amounts of water from the water source, such as treatment plants or reservoirs, directly to various areas within a community. This ensures that there is an adequate supply for both everyday use and emergency situations, such as firefighting.

Primary feeders are designed to maintain high water flow and pressure, which is essential for meeting the needs of the town's residents and businesses. They are typically larger in diameter compared to other types of pipes in the distribution system, allowing them to handle the increased volume of water required. In contrast, secondary feeders usually connect to primary feeders and serve smaller areas, while distributors are smaller lines that deliver water directly to individual consumers or service lines. This hierarchical structure of the water distribution system underscores the importance of primary feeders in maintaining efficient water supply across an entire community.
