What is the minimum residual water pressure required by regulations for public water systems under demand conditions?

30 psi

20 psi

The minimum residual water pressure required for public water systems during demand conditions is essential for ensuring adequate water supply and preventing issues such as water contamination or system malfunctions. Regulations typically dictate that a minimum pressure of 20 psi must be maintained to ensure that water can be adequately delivered to consumers and to maintain the integrity of the water distribution system.

This minimum threshold helps ensure that there is a sufficient driving force to deliver water to all service points in the system effectively, particularly during peak demand times when multiple consumers are drawing water simultaneously. By maintaining this standard, public health and safety concerns are addressed, and the system can perform efficiently under various demand scenarios.
