What is a pressure zone in a water distribution system?

In a water distribution system, a pressure zone refers to a specific area where water pressure is maintained at a certain level to ensure that water can be delivered effectively to consumers without issues related to under- or over-pressurization. This is crucial because water needs to flow through pipes at adequate pressure to reach homes, businesses, and fire hydrants. Maintaining pressure within these zones allows for reliable water delivery and helps in managing the hydraulic performance of the system.

Each pressure zone is designed to meet the requirements of the elevation and demand in that area. In practical terms, utilizing pressure zones allows the distribution system to be segmented, which can help with maintenance and operational efficiency. By managing these zones, water utilities can optimize the use of pumps and maintain consistent service even during peak demand times or other operational challenges.
