What should be monitored in a gravity sewer system to ensure optimal performance?

Monitoring flow rates and access points in a gravity sewer system is essential for ensuring optimal performance. Flow rates indicate the volume of wastewater moving through the system, allowing for the detection of abnormalities that could suggest blockages, overloading, or underutilization of the system. Anomalies in flow rates can prompt further investigation and timely maintenance, facilitating the prevention of backups or overflows.

Access points, such as manholes, provide critical locations for inspections, maintenance, and monitoring the condition of the sewer. Regular assessment of these access points allows operators to identify issues such as inflow and infiltration, clogs, or structural integrity of the system. By ensuring both flow rates and the condition of access points are within expected parameters, the overall functionality and safety of the gravity sewer system are maintained.

In contrast, while the other options may play a role in the overall infrastructure, they do not directly correlate to the day-to-day operational performance of a gravity sewer system. For example, measuring temperature is not typically relevant to monitoring wastewater flow performance. The material composition of pipes is important for understanding longevity and resistance to corrosion but does not provide immediate actionable data for ongoing operations. Similarly, manhole depth is relevant to design and construction but does not have a direct impact on
