What can excessive water pressure lead to in a distribution system?

Excessive water pressure in a distribution system can lead to piping leaks and bursts because the materials used in pipes and fittings are designed to withstand certain pressure limits. When the pressure exceeds these limits, it can cause stress on the system, resulting in cracks or complete failure of pipes. This not only leads to water loss but can also result in damage to infrastructure, increased maintenance costs, and potential service interruptions for customers.

The other options do not accurately reflect the consequences of excessive pressure. For instance, increased efficiency of water delivery might seem advantageous, but it is not a direct result of heightened pressure; rather, it can cause system stress and faults. Consistent pressure across all service lines is a goal in water distribution but excessive pressure typically creates uneven pressure conditions, leading to potential failures rather than consistency. Lastly, enhanced water treatment methods are unrelated to pressure levels in the distribution system, as treatment usually involves water quality processes rather than pressure management.
