StormPROOF® by Frog Environmental, designs, builds, and maintains customized treatment systems that effectively manage and remove pollutants from stormwater runoff.

At Frog Environmental, we understand that managing industrial stormwater runoff is critical to regulatory compliance and environmental protection. That’s why we offer StormPROOF®, a suite of customized stormwater treatment systems engineered to tackle pollutants and help facilities avoid costly NAL exceedances, third-party lawsuits, and Water Board penalties.
Our StormPROOF® systems are designed, built, and maintained with precision—leveraging patented Best Available Technology (BAT) to pre-treat, filter, and polish stormwater before discharge. Whether your site deals with Total Suspended Solids (TSS), Oil & Grease (O&G), metals, nutrients, or nitrogen, we offer scalable solutions tailored to your site-specific needs.
Available Treatment System Options
StormPROOF® 75 GPM
Gravity System (SPG)
Ideal for facilities managing moderate stormwater flow, the StormPROOF® Gravity System targets:
Total Suspended Solids (TSS)
Oil & Grease (O&G)
Select metals (site-specific performance)
This passive, energy-efficient system is an excellent foundation for compliance in most industrial settings.
StormPROOF® Pressurized MetalPROOF System (SPM)
An advanced upgrade to the Gravity System, the Pressurized MetalPROOF System is engineered for more demanding sites. It provides:
Enhanced treatment of TSS and O&G
Comprehensive metals removal (including zinc, copper, lead, etc.)
Ideal for facilities with high metal pollutant concentrations or stricter permit requirements.
StormPROOF® NitrogenPROOF
System (SPN)
Our most advanced configuration, the NitrogenPROOF System includes all the benefits of the MetalPROOF with added nutrient removal capabilities:
TSS, O&G, and full-spectrum metal treatment
Nitrogen compounds (Nitrate + Nitrite)
Phosphorus reduction
Recommended for industries operating in nutrient-sensitive watersheds or under regional nutrient discharge requirements.
