What is the minimum operating water pressure for DWP customers?

The minimum operating water pressure for customers of the Department of Water and Power (DWP) is set at a standard that ensures adequate flow for both residential and commercial use. The correct answer indicates that this minimum pressure is 34.5 PSI. This pressure is essential for ensuring that water can reach homes and businesses effectively, allowing for proper functioning of plumbing systems and appliances.

Understanding the implications of having a minimum pressure helps to appreciate the engineering standards in place that sustain public health and safety. Insufficient pressure can lead to issues such as inadequate supply for water heating, poor performance of showerheads and faucets, and an increased risk of backflow, which could compromise water quality. The value of 34.5 PSI reflects a balance between safety, efficiency, and consumer needs in water distribution systems.
