What is a primary outcome of inadequate water pressure?

Inadequate water pressure can significantly increase the risk of contamination in a water distribution system. When water pressure is insufficient, it may lead to backflow, where contaminated water from the surrounding environment can infiltrate the potable water supply. This situation is particularly concerning in systems relying on gravity or that have multiple pressure zones. Low pressure can also result in stagnation within the pipes, allowing microorganisms to grow and thrive, further risking the safety of the water supply.

In contrast, factors like public satisfaction, service quality, and maintenance costs are negatively affected by inadequate pressure. Low pressure typically leads to complaints from consumers who experience poor service delivery and may cause increased maintenance costs due to system failures. Therefore, recognizing the impact of inadequate water pressure on contamination risk is crucial for maintaining the safety and reliability of public water supplies.
