What is the typical pressure range for a municipal water supply system?

• A. 10 to 20 psi
• B. 20 to 30 psi
• C. 40 to 80 psi
• D. 100 to 120 psi

Answer: (C)

The typical pressure range for a municipal water supply system is generally between 40 to 80 psi (pounds per square inch). This pressure range ensures that water can be effectively distributed throughout the system, reaching homes and businesses with sufficient force for day-to-day use, such as showering, washing dishes, and other household needs. Maintaining this pressure range is crucial because it helps prevent issues like water stagnation or insufficient flow, which could lead to service complaints from customers. A pressure that is too low may result in inadequate supply, while pressure that is excessively high might cause damage to plumbing fixtures and pipes, leading to leaks and other infrastructure problems. Therefore, the choice of 40 to 80 psi reflects the balance needed to ensure reliable and efficient water delivery alongside the safety and longevity of the system’s infrastructure. The other options fall outside of this commonly accepted range, as pressures that are too low won't adequately deliver water, and those that are too high can create risks of physical damage.
