Improve Water Quality
Treatment Solutions for Stormwater, Urban Runoff and Combined Sewer Overflow (CSO) Discharges.
StormTrap’s StormSettler is the first hydrodynamic separator in the stormwater industry to utilize tube settling packs and upflow patterns to promote settlement and capture of sediments.
Designed using computational fluid dynamics and extensive laboratory testing, StormSettler utilizes flow modifiers and tube settlers for effective treatment. Drawing from the inclined plate SiteSaver technology, StormSettler provides extended surface area settling benefits but in a more compact, round structure.

NJDEP certification assures minimal scour during peak flow events, up to 200% of the unit’s treatment flow; this qualifies the unit for online use

Drawing from the inclined plate SiteSaver technology, StormSettler provides extended surface area settling benefits in a compact, round structure
Maximizes sediment capture and retention by equalizing flow throughout the inclined tube pack, which provides a large surface area, small setting distances, and a controlled pollutant pathway
Design prevents sediment deposit in the inlet pipe
Inlet and outlet inverts can be at the same elevations
Can accommodate flow from a catch basin as well as multiple inlet pipes
Online and offline configurations are available
Provides a simple installation process for the contractor, which is very similar to setting a standard manhole structure
On-site supervision available on each project
Accessible for inspection and maintenance
No confined space entry required – Engineered for easy maintenance with a vacuum truck or similar equipment without removing the settling pack
May be equipped with remote monitoring technology to reduce the time and resources required for inspection
When water enters the system, flow modifying components ensure that water flow is efficiently equalized throughout the inclined tube pack, which provides a large surface area, small settling distances, and a controlled pathway for pollutants to be retained within the sump area. The treated water is then directed around an outlet diverter before being discharged from the device through the outlet pipe.
During large storm events, the vertical baffle provides an internal bypass, allowing excess water to pass over the baffle, preventing hydraulic complications upstream.
