VortSentry® HS Stormwater Treatment
The VortSentry HS is a compact stormwater treatment system that uses helical flow technology to enhance gravitational separation of floating and settling pollutants from stormwater. The small footprint of the VortSentry HS makes it an effective stormwater treatment option for projects where space is at a premium.
Compact Stormwater Treatment
The VortSentry HS is a compact, below grade stormwater treatment system that uses helical flow technology to enhance gravitational separation of floating and settling pollutants from stormwater flows. The small footprint of the VortSentry HS makes it an effective stormwater treatment option for projects where space is at a premium.
The VortSentry HS accepts a wide range of pipe sizes to treat and convey a wide range of flows. The unique internal bypass weir allows flows exceeding the treatment capacity to be diverted within the unit eliminating the need for an external bypass structure.
How the VortSentry HS Treats Stormwater
- Untreated stormwater enters the VortSentry HS through an inlet pipe or grate inlet.
- Low, frequently occurring storm flows are directed to the treatment chamber where a tangentially oriented downward pipe induces a swirling motion in the treatment chamber that promotes the separation of suspended solids. Trash and floating debris are also captured in the treatment chamber.
- Moderate storm flows are directed into the treatment chamber through a secondary inlet, which allows for capture of floating trash and debris. The secondary inlet provides for treatment of higher flows without significantly increasing the velocity or turbulence in the treatment chamber.
- Flow exits the treatment chamber through the outlet flow control, which manages the amount of flow that is treated and helps maintain the helical flow patterns developed within the treatment chamber.
- Flows exceeding the systems rated treatment flow are diverted away from the treatment chamber by the flow partition.
- Treated stormwater exits the VortSentry HS via the outlet pipe.

VortSentry HS Configurations
The VortSentry HS is available in three standard configurations. All three configurations are available in 36-inch (900-mm) through 96-inch (2400-mm) diameter manholes.
- Inline (with inlet and outlet pipes at 180º to each other)
- Grated inlet
- A combination of grate and pipe inlets.
VortSentry HS Applications
- Stormwater quality control trash, debris, sediment, and hydrocarbon removal
- Inlet and outlet protection
- Pretreatment for filtration, detention/infiltration, bioretention, rainwater harvesting and Low Impact Development designs.
VortSentry HS Maintenance
- VortSentry HS provides unobstructed access to stored pollutants, making it easy to maintain.
- Maintaining a VortSentry HS 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 BMPs.
Hydrodynamic Separators for Inlet and Outlet Pollution Control
Keep trash and debris out of your lakes, streams and oceans by installing one of our hydrodynamic separators at the inlet or outlet of your drainage system. Our systems - which include the CDS, Vortechs, and VortSentry HS - are most effective on sediments, trash and debris, and oil and grease.
Hydrodynamic Separation for Water Quality
Our hydrodynamic separation products (including the CDS, Vortechs, and VortSentry HS) 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.
Treating Stormwater on Industrial Sites with Hydrodynamic Separation
Our stormwater treatment systems can be utilized on industrial sites and help bring sites into compliance with industrial National Pollutant Discharge Elimination System (NPDES) stormwater permits. We have over fifteen years of experience in the stormwater treatment market, and can provide reliable, flexible and cost-effective solutions to assist in meeting environmental permit requirements. Our hydrodynamic separation systems target sediment, trash and debris, and provide spill capture and containment for low density, non-soluble liquids like motor oil. These systems are typically specified as pretreatment upstream of stormwater filtration, infiltration or detention systems.
Keeping LID and GI sites free from fine sediments, oils, trash, and debris while functioning as designed can be time consuming and costly. The practice of combining LID with treatment systems like the Jellyfish Filter or CDS is becoming more common. Doing so increases water quality, provides a single point of maintenance, promotes proper system functionality, and increases the aesthetic appeal by removing unsightly trash and debris.
