What is the minimum water pressure required for a water distribution system?

For a water distribution system, maintaining adequate pressure is crucial for effective operation, particularly during peak demand times. A minimum pressure of 20 psi during peak demand is generally accepted as a standard guideline. This level of pressure ensures that water can be delivered effectively to residential and commercial users, overcoming friction losses in the pipes and ensuring that adequate flow rates are maintained.

At a pressure below this threshold, the system may struggle to deliver water adequately, resulting in reduced flow and potential interruptions in service. It is vital for firefighting capabilities as well; insufficient pressure can hinder emergency services from accessing ready water supplies during critical moments. Therefore, recognizing the minimum requirement of 20 psi helps to ensure that the system is robust enough to handle varying conditions and demands.
