Wastewater Technology: Precise Data on Conditions in Infrastructure
Delivering Informed Data
SediVision® wastewater technology delivers precise information on the location and quantity of sand, sediment, and debris beneath the dark water of tanks and other wastewater infrastructures.
By knowing where and how much debris has accumulated in structures, operators and managers can make accurate and timely maintenance, cleaning, and budgeting decisions. Armed with informed data about sand and grit accumulation and reliable mapping and quantification of loss of capacity, wastewater facility decision-makers can:
- Proactively address compliance issues
- Optimize energy consumption and efficiency
- Restore loss of capacity within their systems
- Avert disruptions in the wastewater treatment process
- Help ensure seamless operation
- Strategically plan and budget with confidence for sediment removal
- Better uphold environmental standards, helping maintain public health and the sustainability of natural ecosystems
Informed Decisions
Enabling Predictive Maintenance
Thanks to SediVision, for the first time ever, wastewater plant decision-makers and wastewater facility operators can reliably "see" in the opaque water inside tanks, aeration basins, and oxidation ditches.
Using proprietary, patent-pending wastewater technology, SediVision’s on-site crew maps the sediment and grit debris beneath the turbid water. The process does not interrupt service, daily operations, or wastewater plant workers, and there is no need for bypass pumping or draining wastewater facility infrastructure.
The processed data is used to develop a 3D model of the accumulated debris and sediment. Each tank’s loss of capacity information is reported along with the estimated specific volume. Deliverables are provided in PDF format and include:
- Mapped image(s) of the grit and sediment, overlaid on the tank drawing
- A quantity summary with total cubic yards of material in the tank and the percent of lost capacity in each tank as compared to the total tank volume, and
- Wastewater plant operators and managers have confidence that strategic decisions can be made based on genuine hard data.

Restoring Capacity in Wastewater Plant Infrastructure
SediVision® wastewater technology enables precise quantification and mapping of capacity loss in wastewater facility infrastructure. Unlike flow, which is the actual amount of water flowing by a specific point over an identified period of time, capacity represents the ability of wastewater facilities to maintain a target flow rate throughout each step of the treatment process.
Knowledge gained from SediVision allows wastewater treatment plant operators to direct tank cleaning efforts towards structures with the highest accumulation of sand and grit debris. Armed with reliable data, they can restore capacity to their wastewater treatment process and establish an optimal predictive maintenance plan and budget for their treatment facility.
Mapped Infrastructure
Aeration Tank Scan
A utility in Alabama has a 140 ft. diameter aeration tank that it believed needed cleaning. Roughly a quarter million dollars was budgeted for cleaning. To the utility operator’s surprise, little to no material was discovered during the SediVision assessment. These results led to the owner’s peace of mind and the redeployment of limited resources to support other projects.
Pre- and Post-Cleaning Analysis
A Florida utility has a wastewater treatment plant with two 50 ft. x 200 ft. oxidation ditches that were scheduled to be cleaned. SediVision® technology was chosen to help determine the scope and budget of the project. The owner utilized online cleaning based on the location, quantity, and type of material and avoided draining the tank. SediVision data helped the contractor guide its cleaning equipment.
Overhead View of Oxidation Ditch
SediVision scanned a South Florida oxidation ditch to assess whether cleaning was required. The results showed 1,769 cubic yards in the tank, with a loss of capacity of 11.9%. These results gave the wastewater plant management the information to plan and budget better for the cleaning that was necessary.
Mini-Case Study: Lee County, FL
Location:
Lee County (Florida) Water Reclamation Facility Fiesta Village Wastewater Treatment Plant
Problem:
Unknown amount of capacity loss in oxidation ditch.
How SediVision Helped:
SediVision® technology identified over 1769 yards of grit accumulation, equaling a 11.9% capacity loss.
Outcome:
The data provided allowed the wastewater professionals at Lee County to create an accurate cleaning and maintenance budget to present for approval, as well as a timeframe to restore and maintain optimum capacity in that structure.
