What is the primary reason for maintaining proper water pressure in a distribution system?

Maintaining proper water pressure in a distribution system is crucial primarily because it ensures adequate flow throughout the system and helps to prevent contamination. Adequate pressure is essential for the effective delivery of water to consumers, allowing water to reach homes and businesses without interruption. Moreover, proper pressure helps to keep the water flowing smoothly, which can minimize the risk of stagnant water in the system. Stagnant water is more susceptible to contamination from microorganisms and other pollutants.

In addition, maintenance of appropriate water pressure prevents backflow, a situation where contaminated water could potentially be drawn back into the potable water supply due to a drop in pressure. This is important for protecting public health and ensuring the safety of the drinking water supply in the system. Correct pressure levels are thus a critical component of effective water distribution management, serving both functional and safety purposes.
