Tracking LoC with SediVision: Benefits of Comparison Data Before & After Anomalous Events

New! This loss of capacity (LoC) case study of a Central Florida wastewater facility highlights the benefits of ongoing SediVision reporting in tracking loss of capacity, especially when there are sudden changes in debris and sediment inside wastewater structures.

Loss of capacity due to sand, grit, and debris happens over time, but when anomalous events occur, it can quickly change circumstances in key structures, leading to the need for cleaning ahead of schedule.

Serious LoC events can be sudden… or the result of hidden issues

  1. Severe weather
  2. Bypassing grit removal during emergency flow events
  3. Pump or equipment failure
  4. Pipe deterioration
  5. Inefficient mixing or aeration

These things and more can seriously impact the performance of wastewater structures. Being proactive in maintaining performance is critical to every wastewater facility, especially Florida wastewater facilities subject to BMAP (Basin Management Action Plan) targets. Detention time is crucial for processing nutrients, ensuring proper oxygenation, and other key targets prior to releasing treated water back into the local watershed. Loss of capacity can reduce detention time, leading to failed targets or increased budgets to bring structures up to standards.

In this LoC Case Study:

  • Loss of capacity reporting examples across two assessments, 2022 and 2024
  • Multiple before and after views of the assessed structure, demonstrating the range of visualization available in SediVision reporting
  • Visual sample of increases in grit and debris in an oxidation ditch after an anomalous event
  • The value of benchmarking loss of capacity and debris levels inside tanks for budgeting and reporting
