What are primary feeders in a water distribution system?

Primary feeders in a water distribution system are referred to as large mains that carry water to a section of the city. These mains are crucial because they are designed to transport substantial volumes of water from the water source, such as a treatment plant or reservoir, to various parts of the distribution network. They typically have larger diameters to accommodate the higher flow rates needed for urban areas, ensuring adequate supply for both everyday use and firefighting needs.

The size and capacity of primary feeders are essential to maintaining pressure throughout the distribution system, which enables water to reach smaller pipes and ultimately individual consumers. Understanding the role of primary feeders highlights their importance in urban planning and emergency response, including fire services, as they ensure the availability of sufficient water during critical situations.
