StormFilter Catch Basins: A Quick Guide

A StormFilter® catch basin is an advanced stormwater treatment system developed by Contech Engineered Solutions. Designed for commercial and industrial sites, this technology offers a reliable, high-performance way to remove pollutants from stormwater runoff before it enters local waterways or municipal systems.

For commercial property managers and business owners, using a Contech StormFilter system helps meet strict environmental regulations, protect infrastructure, and support sustainable site development. Whether you need new installation or ongoing StormFilter maintenance, iSTORMWATER is your go-to partner for reliable service.

What Is the Contech StormFilter Used For?

The Contech StormFilter is engineered to remove a wide range of pollutants from stormwater, including:

• Sediment
• Nutrients like phosphorus and nitrogen
• Oils and hydrocarbons
• Heavy metals (zinc, copper, etc.)
• Trash and debris

It’s ideal for high-traffic commercial sites, industrial facilities, parking lots, and any impervious surfaces that generate contaminated runoff.

These systems are also approved under many stormwater regulations, including the EPA’s Clean Water Act and local NPDES permit requirements.

How the Contech StormFilter Catch Basin Works

A StormFilter catch basin consists of a below-grade vault containing multiple rechargeable filter cartridges. These are filled with engineered media to target specific pollutants. Here’s how the system works:

1. Stormwater enters the vault, where debris and floatables are removed in a pretreatment chamber.
2. Water then flows through StormFilter cartridges, each filled with custom filter media such as:
   • Perlite (for sediment)
   • Zeolite (for metals and nutrients)
   • Granular activated carbon (for hydrocarbons and organics)
3. Pollutants are captured through physical, chemical, and biological filtration.
4. The clean water exits the system via underdrain piping.

The result is significantly cleaner discharge that reduces environmental impact and helps commercial properties stay in compliance.

Why StormFilter Maintenance Is Critical

Like any filtration system, the Contech StormFilter requires routine maintenance to perform effectively. Over time, the filter cartridges become saturated with contaminants, reducing flow capacity and pollutant removal efficiency.

StormFilter maintenance services typically include:

• Inspection of vaults and access points
• Removal and replacement of filter cartridges
• Cleaning of sumps and pretreatment chambers
• Flow testing and performance checks

At iSTORMWATER, we provide comprehensive StormFilter service to ensure your system remains compliant, efficient, and long-lasting.
