What is a common consequence of failing to maintain water distribution infrastructure?

Failing to maintain water distribution infrastructure can lead to an increased risk of failures and leaks. This occurs because aging pipes, valves, and other system components can deteriorate over time due to wear, corrosion, and external factors. When maintenance is neglected, the likelihood of structural failures rises, which can result in water loss, contamination of the water supply, and interruptions in service to customers. Addressing maintenance issues proactively helps to ensure the reliability and integrity of the water distribution system, preventing costly repairs and potential public health hazards.

In contrast, the other options suggest outcomes that are not generally associated with poor maintenance. Improved water taste and enhanced public trust would typically result from effective management and maintenance of the system, rather than its decline. Reduction in energy efficiency can be a consequence of issues like leaks or malfunctioning components, but it is not as direct a consequence of failing maintenance as the risk of failures and leaks is.
