What is one consequence of failing to maintain a collection system?

Maintaining a collection system is crucial for its effective operation and longevity. One significant consequence of neglecting maintenance is the increased risk of sewer overflows and environmental contamination. Over time, wear and tear or blockages can lead to system failures. When these systems are not routinely inspected and maintained, they can become clogged or damaged, resulting in sewage spilling into the environment. This not only poses health risks but also leads to contamination of local water bodies, negatively impacting ecosystems and public health. Addressing these issues requires considerable resources, highlighting the importance of proactive maintenance to prevent such dire consequences.

The other options do not directly correlate with the consequences of failing to maintain a collection system, as enhanced efficiency and reduced water usage imply effective management rather than the outcomes of neglect, while increased costs of construction represent a different aspect of system management.
