    Flow Monitoring

    We treat flow monitoring not as an afterthought, but as the cornerstone of proactive infrastructure management. If you’re scrambling every time treatment costs climb or sewer backups strike, it’s time to get ahead of the game. Our flow monitoring services deliver targeted, data-driven insights into your sewer system’s performance—without requiring you to tear up the streets or drain your budget.

    Flow monitoring is more than measuring water movement—it’s the system’s stress test in real time. By installing advanced sensors and loggers in manholes or strategic sewer basins, we capture critical metrics like flow rate, velocity, and depth during wet and dry weather. This data lays the foundation for identifying inflow/infiltration (I/I) hotspots, optimizing capacity, and guiding long-term rehab decisions with surgical precision—no guesswork involved.

    Why Flow Monitoring Isn’t Optional—It’s Essential

    1. Sniff out hidden costs
      Inflow and infiltration—excess groundwater or stormwater entering your sewer system—can silently balloon treatment loads and drive up costs. Flow monitoring surfaces these invisible culprits by revealing surges tied to precipitation events or soil saturation.
    2. Pinpoint fixes, don’t blanket apply
      Rather than conducting system-wide sweeps that waste time and money, flow data lets you zero in on problem basins. You can then target rehabilitation—like lining or grouting—where it’s truly needed, not where it gets thrown in as an equal.
    3. Clear the air—or the water—with numbers
      Flow monitoring equips you with the actual numbers behind surcharging and overflows. Are the surges from heavy rain (inflow) or persistent groundwater leaks (infiltration)? Data clarity means smarter fixes, faster.
    4. Support models and comply with confidence
      When you’re building a hydraulic model or working under regulatory mandates (like CMOM or Consent Decrees), accurate, real-world flow profiles are critical. Flow data ensures your modeling isn’t just theory—but real, actionable intelligence.
    5. Track performance and improvements over time
      Flow monitoring isn’t a one-and-done play. It helps you validate rehab efforts, track trends, and justify capital improvements—especially if you transition to a permanent monitoring network.

    GCU’s Smart, Hands-On Approach

    1. Strategic placement, planned monitoring
      We help define which basin or manhole locations make the most sense for flow sensors, ensuring you collect meaningful data across dry and wet weather cycles.
    2. Best-fit monitoring gear
      From in-pipe devices that track velocity and depth to no-contact sensors mounted below lids, we match the right tech to your goals—temporary study or long-term insight.
    3. Data you can actually use
      We translate raw flow streams into clean hydrographs, scatter plots, and actionable trends—highlighting base flow, rainfall-driven peaks, and I/I response patterns.
    4. Proactive support
      Our technicians handle installation, calibration, periodic maintenance, and data verification. GCU ensures sensor uptime and accuracy across the board.
    5. Model-ready analytics
      Whether you’re refining hydraulic models or evaluating treatment capacity, we provide the calibrated, historical flow insights you need—like ready-to-go Excel sheets or CSV datasets.

    Why GCU Delivers More Than Data

    • Design-build integration: Flow monitoring isn’t just a data point—it’s the first step toward strategic rehab. We roll the insights into lining, grouting, or structural fixes tailored to reduce I/I at the source.
    • Budget-smart planning: With better data comes better dollar decisions. Targeted fixes let you do more with less—and prove ROI to stakeholders.
    • Operational empowerment: You get granular visibility into your system’s behavior. No surprise surges, no reactive scrambling—just confident system management.
