What is the typical pressure range for municipal water supply systems?

The typical pressure range for municipal water supply systems is generally between 20 and 80 psi (pounds per square inch). This range is ideal for ensuring adequate water flow and pressure for residential and commercial use, allowing for effective operation of plumbing fixtures, appliances, and fire protection systems.

A pressure below 20 psi could lead to insufficient flow rates, causing issues with water delivery to homes and businesses, especially in cases where multiple outlets are used simultaneously. On the other hand, pressures above 80 psi may pose risks such as pipe burst or damage to plumbing fixtures, which can lead to costly repairs and inefficiencies in the system. Hence, maintaining the pressure within this range strikes a balance that promotes both functionality and safety in municipal water supply systems.
