Stormceptor®

Stormceptor is a hydrodynamic separator designed to protect waterways from hazardous material spills and stormwater pollution, including suspended sediment, free oils, floatables and other pollutants that attach to particles.

Why Contech Start a Project

What is Stormceptor?

Stormceptor is a hydrodynamic separator offering a range of versatile treatment systems that effectively remove pollutants from stormwater and snowmelt runoff. Stormceptor is flexibly designed to protect waterways from hazardous material spills and stormwater pollution, including suspended sediment, free oils, and other pollutants that attach to particles, no matter how fierce the storm. The Stormceptor’s patented scour prevention technology ensures pollutants are captured and contained during all rainfall events.

How Does Stormceptor Work?

  • Stormwater enters the Stormceptor through the inlet pipe(s) or inlet grate. A specially designed insert slows the water down and directs it to a lower chamber
  • The non-turbulent chamber allows free oils and debris to rise, and sediment to settle
  • Free oils and other floatables remain trapped
  • Sediment settles and lies dormant and retained for later removal
  • Stormceptor’s patented scour prevention technology ensures pollutants are captured and contained during all rainfall events, even extreme storms
  • Treated stormwater exits the unit via the outlet pipe

Stormceptor Features and Benefits

3rd party verified performance (Sediment & Oil) Treatment with confidence

Stormceptor Performance Verifications

With more than 20 years of industry experience, Stormceptor has been tested and verified by some of the most stringent technology evaluation organizations in North America. Stormceptor has been performance verified through numerous State, Provincial, and Federal verification programs, including;

  • NJCAT
  • Washington ECOLOGY
  • EN858 Class 2

Stormceptor STC - Performance Testing Results

  • 97.8% Oil removal, 83% Inorganic Sediment Removal, 73% Organic Particle Removal - Coventry University - Full Scale Testing
  • 87% TSS Removal, 99% TPH Removal - Field Monitoring - Seattle, WA
  • 93% TSS Removal, 82% TPH Removal - Field Monitoring - Westwood, MA
  • 76% TSS Removal, 65% TKN Removal, 32% TP Removal - Field Monitoring - Como Park, MN
  • 75% TSS NJCAT Verified Performance per NJDEP’s weighted removal and laboratory test protocol
  • Scour Prevention NJCAT Verification per NJDEP’s 2009 laboratory test protocol demonstrating the Stormceptor STC can be successfully applied in an on-line configuration
  • No Scour - Minnesota Department of Transportation (MN DOT) Research Services evaluates the susceptibility of the Stormceptor to scouring of collected sediments. Report concluded that the unit does not scour at high flows as long as sediment depth does not exceed maintenance level

Stormceptor Maintenance

  • Stormceptor provides unobstructed access to stored pollutants, making it easy to maintain.
  • Maintaining a Stormceptor is a simple process that can be easily accomplished using a vacuum truck, with no requirement to enter the unit.
  • Contech has created a network of Certified Maintenance Providers to provide maintenance on stormwater BMP’s.

Trash Removal

Many municipalities have enacted specific trash control strategies in response to TMDLs or municipal stormwater permit requirements. To address these issues, stormwater managers, municipal officials, and other stakeholders need solutions like Contech's Catch Basin Inlet Filters, Debris Separating Baffle Box, and CDS hydrodynamic separators that can remove trash and TSS, which are easy to maintain and can easily be implemented in a retrofit scenario.

Hydrodynamic Separation for Water Quality

Our hydrodynamic separation products (including the CDS, Cascade Separator, SciCloneX, Vortechs, and Stormceptor Systems) are reliable, easy to install, and offer high-performance, proven, stormwater pollutant removal. The systems are widely accepted for effective solids removal and can be designed to achieve your site treatment goals - including TMDL requirements for TSS and trash.

Pretreatment to Storage

Our hydrodynamic separators are frequently installed upstream of detention and infiltration systems as pretreatment devices.  By capturing the majority of sediment, hydrocarbons and trash and debris upstream of the storage system, maintenance becomes much easier as material is congregated into a smaller device with clear access for cleanout.  Additionally, by utilizing pretreatment upstream of infiltration systems, sediment that would have clogged the stone voids in the storage envelope surrounding the storage chamber can be captured before entering the storage system thus extending the longevity of the entire system.

Pretreatment for Rainwater Harvesting

Our hydrodynamic separation products are ideal solutions for preatreatment to rainwater harvesting.  Not only do they improve the overall water quality, they also provide protect the pumps and controls from being overburdened with material that could clog and damage the mechanical system.
