Providerly, digital twins can detect blockages caused by fat, oil, and graase (FOG) deposits or root intrusion byanalizing flow velocity and depth trends. Operators receive alerts andd can dispatch cleaning crews proactively, reducing the frequency of emergency callout and public incommence.

Optimized Maintenance Scheduling

Reactive condition- fixing problems after they happen - is locsive and distributivie. Digital twins eable condition- based and predictive conditione competitivies. Instead of cleaning every pipe on a fixed schedule, utilites can target sections that are approaching critial condition. This approach reduces unnecesary consiance costs while ensuring highrisk assets recedive attion whereeeeed.

For instance, a digital twin might predict that a pump station 's energy consumption is rising due te wear on impeller blades, allowing consumance to o be scheduled during low- flow period. The result is lower energy bils, fewer unplanned outages, andd extended asset lifespan.
