Stormceptor® Stormwater Treatment Systems

When it rains, oils, sediment and other contaminants are washed from paved surfaces directly into our storm drains and waterways. Non-point source pollution, such as stormwater, now accounts for 80% of water pollution in North America.

Stormceptor Models
For industrial, commercial, residential and government sites – virtually anywhere there is pavement, the following models are available for various site conditions:

Inline Stormceptor® (animated demonstration)
Our standard design for most stormwater treatment applications requires only a 1 inch drop from the inlet pipe to the outlet pipe.

Inlet Stormceptor® (animated demonstration)
The Inlet Stormceptor STC 300 is designed to replace a catch-basin, featuring an open grate at the surface. Ideal for small parking lots, loading bays, gas stations and other spill-prone areas. When used as a flow through unit, a 3 inch drop is required from the inlet pipe to the outlet pipe.

Submerged Stormceptor® (animated demonstration)
The Submerged System functions in partially submerged pipes, making it ideal for coastal areas.

Series Stormceptor® (animated demonstration)
Designed to treat larger drainage areas, the Series Stormceptor System consists of two adjacent units that function in parallel. This design eliminates the need for additional structures, reducing excavation and material costs. A 3 inch drop is required from the inlet pipe into the first unit to the outlet pipe in the second unit.

Key Features & Benefits

Removing more pollutants
Stormceptor removes more pollutants from stormwater than any other separator.

• Maintains continuous positive treatment of total suspended solids (TSS) year-round, regardless of flow rate
• Designed to remove a wide range of particle sizes, (from 20 microns to 2,000 microns) including free oils, heavy metals
• Can be designed to remove a specific particle size distribution (PSD)

A calm treatment environment

• Stormceptor slows incoming stormwater to create a non-turbulent treatment environment, allowing free oils to rise and sediment to settle
• Patented scour prevention technology ensures pollutants are captured and contained during all rainfall events, even extreme storms

Proven performance
Recent tests conducted for the New Jersey Department of Environmental Protection (NJDEP) found Stormceptor has the highest (TSS) removal rate of seven stormwater treatment devices tested. During NJDEP’s rigorous testing, Stormceptor did not scour with the sediment chamber loaded to design capacity.

Design flexibility Makes Stormceptor Extremely Versitile

Easy to install and easy to maintain, Stormceptor stormwater treatment systems are flexible and versatile, allowing you to address unique site challenges.

Small footprint
Stormceptor’s small footprint saves time and money with limited disruption to your site.

• Footprints range from a diameter of 48” to 144” for standard units
• Patented design eliminates the need for external bypass piping
• The result - lower overall construction costs and site disturbance

Multiple pipe inlet

• More than one storm drain can connect to a single unit, eliminating the need for additional structures
• Stormceptor can be designed to accommodate a wide range of pipe sizes
• Stormceptor can also be used as a bend structure

Low head loss
With a documented K-factor of only 1.3, and a minimal drop between the inlet pipe and the outlet pipe, Stormceptor is compatible with existing infrastructure and ideal for retrofit applications. Many structural BMPs fail to provide documented head loss test results, leaving the designer to estimate the impact on their system.

Hydrocarbon containment

• Effective for dry weather spill capture and containment of free oil
• Manufactured joints conforming to ASTM C-443 – rubber gaskets prevent infiltration and exfiltration, minimizing the potential for the migration of pollutants into surrounding soils
• Double-wall configuration of the fiberglass insert skirt and the reinforced concrete wall provides a secondary containment system for hydrocarbons and prevents oil from permeating through the unit’s wall over time

Easy access and maintenance

• No confined space entry – routine maintenance is accomplished with a standard vacuum truck
• Access for inspection and maintenance is completed through an access cover at the finish grade elevation
• Annual maintenance is recommended

HS-20 or greater loading capacity
All Stormceptor units are designed to meet AASHTO HS-20 loading criteria, making them ideal for busy traffic zones such as roads or parking lots. Stormceptor units can also been designed for sites with higher loading requirements such as airports and port facilities.

Designed for reliability
With a patented fiberglass insert encased in steel reinforced concrete, and with no moving parts that require maintenance or repair, Stormceptor units can operate for decades with regular inspection and maintenance.

Inspection and Maintenance. Easy. Convenient.

When it rains, oils, sediment and other contaminants are captured and contained by over 18,000 Stormceptor units operating worldwide. While Stormceptor’s patented scour prevention technology ensures captured pollutants remain in the unit during all rainfall, the accumulating pollutants must eventually be removed as part of a regular maintenance program.

If neglected, oil and sediment gradually build up and diminish any unit’s efficiency, harming the environment and leaving owners and operators vulnerable to fines, surcharges and bad publicity.

Ease, frequency and cost of maintenance are often overlooked by specifiers when considering the merits of a stormwater treatment system. In reality, maintenance is fundamental to the long-term performance of any stormwater treatment device.

While regular maintenance is crucial, it shouldn’t be complicated. An on-going maintenance program with Stormceptor is convenient and practically effortless. With virtually no disruptions, you can concentrate on your core business.

Easy access
Both inspections and maintenance are conducted above ground from a standard surface access cover, eliminating the need for confined space entry into the unit. Your site remains undisturbed, saving you time and money.

Quick inspections
Inspections can easily be carried out from any surface access cover through a visual inspection of the orifice and drop tee components. A sludge judge and oil dip-stick are all that’s needed for sediment and oil depth inspections.

No muss, no fuss…and fast
Maintenance is performed quickly and inexpensively with a standard dual compartment vacuum truck. Servicing usually takes less than two hours, with no disruption to your site.

Maintenance recommendations

• Units should be inspected after installation, prior to being put into service.
• Inspect every three months for the first year of operation to determine incoming sediment load.
• In subsequent years, inspections can be based on first-year observations or local requirements.
• Cleaning is required once the sediment depth reaches 15% of storage capacity, (generally taking one year or longer). Local regulations for maintenance frequency may vary.
• Inspect the unit immediately after an oil, fuel or chemical spill.
• A licensed waste management company should remove captured petroleum waste products from any oil, chemical or fuel spills and dispose responsibly.

A complete stormwater management plan for Stormceptor extends beyond installation and performance to regular maintenance. It’s the smart, cost-effective way to ensure your unit continues to removes more pollutants than any other separator for decades to come.

Stormceptor Models

For industrial, commercial, residential and government sites – virtually anywhere there is pavement, the following models are available for various site conditions:
