What may happen if water pressure is too high in a distribution system?

When water pressure in a distribution system is too high, the most significant risk is that the pipes may burst. This can lead to leaks, which not only compromises the integrity of the distribution system but can also result in loss of water and potential damage to surrounding infrastructure. High pressure increases the stress on the materials of the pipes, which can exceed their structural limits. Over time, this can cause them to crack or rupture, leading to widespread failures in the system and necessitating costly repairs or replacements. Managing water pressure is crucial to ensure the longevity of the distribution system and maintain the reliable delivery of water to consumers.

The other options do not directly relate to the consequences of high water pressure. For instance, all water being chlorinated is concerned with water treatment processes rather than pressure issues, freezing relates to temperature rather than pressure, and the ability of water to reach higher elevations depends more on pressure differentials and system design, not solely on high pressure. Hence, the scenario of high pressure resulting in pipe bursts is the critical concern in water distribution systems.
