What are key indicators of collection system performance?

Key indicators of collection system performance focus on the operational efficiency, reliability, and overall effectiveness of the system. Flow rates, blockage frequency, and maintenance costs provide essential metrics for evaluating how well a collection system functions.

Flow rates indicate the volume of wastewater being transported through the system, which helps assess whether the system is capable of handling current and projected demands. High flow rates can signal effective transportation capabilities, while irregularities or drops in flow may indicate blockages or inefficiencies.

Blockage frequency is another critical metric, as frequent blockages may suggest issues with system design, maintenance practices, or the inflow of inappropriate materials. A higher frequency of blockages can lead to overflows, increased maintenance needs, and potential environmental hazards, making its monitoring vital for ensuring system reliability.

Maintenance costs are directly tied to the overall performance of the collection system. Regular, costly maintenance can indicate performance issues. Lower maintenance costs suggest effective management and operation of the system, reflecting its robust capacity to function with minimal disruptions.

In summary, monitoring flow rates, blockage frequency, and maintenance costs provides comprehensive insight into collection system performance, making option B the most relevant choice.
