What may result from a main break in the distribution system?

A main break in the distribution system can lead to a loss of pressure, which is significant for several reasons. When pressure in the water distribution system drops, it creates the potential for contaminants to enter through cracks or openings in the system, particularly if there is a negative pressure. This phenomenon is known as backflow, where external water—potentially containing pollutants—can be drawn into the distribution network, compromising the integrity and safety of the drinking water supply.

Maintaining adequate pressure is crucial for protecting public health, ensuring that contaminants do not infiltrate the system. This loss of pressure, along with the risk of contamination, highlights the importance of promptly addressing main breaks to safeguard water quality and the health of the community. This demonstrates why the identification of loss of pressure as a consequence of a main break is essential in understanding the implications on water safety and operational integrity within the distribution system.
