What is a pressure zone in a water distribution system?

A pressure zone in a water distribution system refers to an area where the water pressure is maintained within a specific range. This is essential for ensuring that end users receive adequate water supply at the appropriate pressure, which is necessary for effective water delivery and to avoid issues such as low flow rates or inadequate service.

Maintaining pressure within a specified range allows for efficient operation of the distribution system, is critical for fire protection, and helps to prevent contamination from backflow. By defining distinct pressure zones, water systems can manage varying topographical challenges within a region, ensuring that pressure is adequate in both elevated areas and throughout the entire system.

This technical management of pressure zones is fundamental to the overall health of the water distribution network, ensuring reliability, efficiency, and safety in water service delivery.
