What is the minimum water pressure that suppliers aim to maintain in the distribution system?

The minimum water pressure that suppliers typically aim to maintain in the distribution system is 20 PSI. This level of pressure is essential to ensure that water can be delivered effectively to homes and businesses. Maintaining at least 20 PSI helps ensure that adequate water flow is available for various needs, including domestic use, fire protection, and ensuring that water can reach higher floors in multi-story buildings.

This pressure threshold is also important for the prevention of stagnation in the system, which can lead to water quality issues. Lower pressure can result in inadequate supply during peak demand times, which may affect not only individual households but also the overall performance and reliability of the water distribution system. Thus, striving for a minimum of 20 PSI is a standard practice in water supply management to balance the need for adequate pressure against operational efficiency and infrastructure integrity.
