What is the significance of maintaining a minimum pressure in a distribution system?

Maintaining a minimum pressure in a water distribution system is crucial for ensuring adequate flow. Sufficient pressure guarantees that water can reach all the necessary points in the distribution network, including residences, businesses, and fire hydrants. If the pressure falls below the minimum threshold, it can lead to inadequate water supply for consumption, hygiene, and firefighting purposes.

In addition to flow, proper pressure helps to prevent issues such as backflow, which can contaminate the water supply and undermine public health. It acts as a driving force that helps to push water through pipes and throughout the system effectively. High pressure also supports the movement of water against gravity in elevated areas or tall buildings, ensuring consistent supply and service delivery. Thus, maintaining minimum pressure is essential for operational efficiency and public safety in water distribution systems.
