What is the minimum required water pressure maintained under normal conditions in a distribution system?

The minimum required water pressure maintained under normal conditions in a distribution system is 35 psi. This pressure is essential for ensuring that water can effectively flow through the distribution system and reach consumers without issues such as inadequate flow or pressure drops that could occur under higher demand situations.

A pressure of 35 psi is generally considered sufficient to provide adequate service levels for residential and commercial needs while also helping to mitigate issues related to contamination and maintain safe water quality. This standard helps ensure that water can travel through the system to reach various outlets in buildings, such as faucets and showers, while also maintaining fire protection capabilities when needed.

Understanding this minimum requirement helps operators ensure compliance with regulations and maintain efficient operations within the water distribution system.
