As stormwater quality regulations become more stringent, engineers need a filtration device that can tackle the most challenging pollutants and provide the flexibility to meet the needs of a variety of sites.
The Stormwater Management StormFilter® is an underground stormwater treatment device that houses rechargeable, media-filled cartridges that trap particulates and adsorb pollutants from stormwater runoff such as total suspended solids, hydrocarbons, nutrients, metals, and other common pollutants. With media options to target multiple or specific pollutants and multiple system configurations, the StormFilter provides engineers with a flexible and reliable manufactured treatment technology. Its performance has been verified through field and laboratory testing by some of the most stringent stormwater technology evaluation organizations.
| Feature | Benefit |
|---|---|
| Siphon actuated, high surface area media cartridges | Stormwater is drawn evenly through the filter media providing efficient, effective stormwater treatment |
| Multiple cartridge heights | Flexibility to meet site-specific hydraulic needs and reduce system size and costs |
| Multiple media options | Ability to target specific pollutants of concern including TSS, phosphorus, and heavy metals |
| Internal peak bypass and multiple configurations | Design flexibility to meet your unique site requirements |
| Maintenance intervals of one to five years | Fewer maintenance events and reduced long-term ownership costs |
| NJDEP Certified and WADOE General Use Level Designation for Basic and Phosphorus Treatment | Certified pollutant capture with confidence |
| Arrives at the jobsite fully assembled | Factory assembly ensures quality and a simple, fast installation onsite |
Flexibility to reduce size and costs...
Every site is different, and one size does not fit all. Multiple cartridge heights give you design flexibility to design the StormFilter specifically for your site and reduce the cost of the system for the owner.
Flexibility to accommodate flows, project footprints, and hydraulics ...
The structures that house the filter cartridges can be constructed in a variety of ways to accommodate a wide range of flows, project footprints, and variable hydraulic conditions. Standard configurations include catch basin, manhole, vault, and curb inlet. Advanced configurations include:
The StormFilter is designed for simple, predictable maintenance that helps reduce long-term operating costs. All StormFilter structures provide easy access for inspection, media replacement, and cleaning.
StormFilter maintenance typically includes:
Designing, manufacturing and installing high-volume stormwater detention and treatment systems requires expert engineering, planning, and logistical support to manage costs and keep the project on schedule and under budget. When you need a proven, large scale stormwater management system, “Go Big” with Contech.
The Stormwater Management StormFilter, Jellyfish Filter, and the Kraken Filter provide the highest level of treatment and meet the most stringent regulatory requirements. These low maintenance systems combine pretreatment and filtration, and are able to target site-specific pollutants to meet your water quality goals. Our field-proven products have earned hundreds of standalone BMP approvals from regulatory agencies nationwide.
The Stormwater Management StormFilter, Jellyfish Filter, and the High Capacity Kraken Filter can be easily configured as decentralized pretreatment systems for Low Impact Development Designs.
Media filtration systems - like our StormFilter, Jellyfish Filter, and Kraken Filter are able to remove the most challenging pollutants from stormwater, including total phosphorus, soluble metals, oil, and very fine particles. Available in a variety of configurations (vault, manhole, catch basin, high flow and volume), these systems can be engineered to treat a wide range of flows within your drainage system and capture pollutants prior to discharge off-site.
Many regulatory agencies have established criteria for sizing stormwater treatment devices to meet their water quality standards. Depending on local requirements, the StormFilter may be sized using flow-based, volume-based, or attenuated/mass-based methodologies. Please refer to the Sizing Methodologies for the Stormwater Management StormFilter document for specific guidelines.
For flow-based preliminary sizing, the water quality treatment flow rate is required. If the unit needs internal bypass, Contech will also need to know the peak storm flowrate. For volume and mass-based/attenuated designs, please contact your local Contech Stormwater Consultant for the necessary criteria to properly size the system adhering to local requirements.
StormFilter cartridges are typically replaced every 1 to 5 years, depending on site conditions, pollutant loading, and maintenance frequency. Routine inspection and maintenance should be used to determine actual replacement timing. Sites with higher sediment, trash, or construction-phase loading may require more frequent service or earlier cartridge replacement.
A detailed maintenance decision tree can be found in the StormFilter Inspection and Maintenance Guide.
StormFilter maintenance costs differ based on several factors, including the size of the vault or manhole, the number and height of cartridges that need to be replaced, site access considerations, geographic location, disposal requirements, and local labor rates. Maintenance frequency can also affect cost and is influenced by site conditions such as sediment loading, trash and debris accumulation, upstream pretreatment, and the amount of runoff treated by the system.
Because these variables can vary significantly from site to site, StormFilter maintenance costs are typically evaluated on a project-specific basis. For the most accurate estimate, contact a Contech Certified Maintenance Provider to review the system size, cartridge count, site layout, and inspection history.
