What Environmental 21 does

Environmental 21 (ENV21), founded in 1996 and headquartered in Batavia, New York, designs and manufactures mechanical stormwater treatment systems sold primarily to government/municipal customers and commercial/industrial facilities. The company offers a portfolio of seven core products — StormPro, V2B1, UniStorm, ESK Koala, UniScreen, PuriStorm, and EnviroTrap — that use gravity separation, hydrodynamic swirl flow, coalescing media, and mechanical screening to remove Total Suspended Solids (TSS), hydrocarbons, floatable debris, and phosphorus from stormwater runoff. The flagship StormPro is a single-structure system with internal bypass achieving 80% TSS removal, while the ESK Koala oil/water separator achieves less than 5 ppm release at flow rates exceeding 5,000 gpm. Several products hold NJCAT Verified/NJDEP Certified status, and StormPro carries NYSDOT conditional approval, positioning the company within U.S. public infrastructure procurement channels.

The company operates a sales-led, direct go-to-market model staffed by professional engineers and project managers who support customers from regulatory approval through installation. Products are custom-quoted with no public pricing, and the company leverages a global network of local pre-cast concrete affiliate manufacturers to reduce production and shipping costs. Marketing channels include the company website, a technical library of 20+ downloadable resources, and trade show presence at the NPCA Precast Show, StormCon, and WEFTEC. Environmental 21 is a privately held, founder-owned, bootstrapped business with 1-10 employees and no institutional investors disclosed. The company has accumulated thousands of installed systems worldwide over more than 25 years of operation. The customer base is split vertically between state and local transportation departments (notably NYSDOT) and commercial/industrial developers needing EPA Phase II compliance. Notably, the most recent news activity on the company's website dates to 2020, and no post-2020 product launches, funding events, or growth metrics are documented in the available data.

Core offering

Environmental 21 designs, manufactures, and sells proprietary mechanical stormwater treatment systems used to remove Total Suspended Solids (TSS), floatable debris, hydrocarbons, oils, and phosphorus from stormwater runoff. The company offers a portfolio of seven core products (StormPro, V2B1, UniStorm, ESK Koala, UniScreen, PuriStorm, EnviroTrap) that use gravity separation, hydrodynamic separation, and media filtration technologies housed in standard pre-cast concrete structures. Sales are accompanied by professional engineering design services covering regulatory approval, sizing, specifications, and cost estimates for municipal and commercial installations.

Product overview

Environmental 21 (ENV21) offers a comprehensive portfolio of mechanical stormwater treatment systems designed to help meet EPA Phase 2 regulations and local watershed protection requirements. The product line consists of seven distinct core products: StormPro (flagship single-structure system with 80% TSS removal), V2B1 (pre-cast two-manhole system), UniStorm (flow diffuser system), ESK Koala (high-efficiency oil/water separator), UniScreen (vault/manhole screening system), PuriStorm (media cartridge filtration), and EnviroTrap (catch basin insert). These products range from catch basin inserts to full treatment vault systems, addressing various treatment needs from gross pollution removal to high-efficiency oil/water separation, with several products carrying NJCAT/NJDEP certification and NYSDOT conditional approval.

• Advanced Drainage Systems (ADS): Leading public manufacturer of water management solutions, primarily known for corrugated HDPE pipe but with an expanding stormwater treatment portfolio. Overlaps with ENV21 in stormwater quality and detention end markets with materially greater resources and channel reach.
• Contech Engineered Solutions: One of the largest U.S. manufacturers of stormwater management products including hydrodynamic separators, filtration systems, and detention solutions. Competes with ENV21 across the full product portfolio serving municipal and commercial customers, but at substantially greater scale and broader geographic reach.
• Rinker Materials: Manufactures concrete pipe, box culverts, and stormwater management products for infrastructure projects. Competes in adjacent stormwater and water infrastructure markets where ENV21's precast-based systems are deployed, with a much broader portfolio and deeper DOT relationships.
• Forterra: Major manufacturer of water and stormwater infrastructure products including concrete pipe, precast structures, and water management systems. Competes in adjacent stormwater and water infrastructure markets where ENV21's precast-based systems are deployed, with substantially greater scale.
• Oldcastle Infrastructure: A CRH company providing comprehensive stormwater management solutions including precast structures, treatment devices, and drainage products. Substantially larger competitor serving the same municipal and DOT end markets as ENV21 with a broader product portfolio.

Direct peers

• StormTrap: Manufactures stormwater management systems including detention, retention, and water quality treatment products. Closely comparable niche specialist overlapping with ENV21's UniStorm and broader stormwater treatment portfolio in the same regulatory-driven municipal market.
• Vortechnics: Manufactures stormwater treatment systems including hydrodynamic and swirl-flow separators designed for TSS removal in municipal and commercial applications. Directly comparable niche specialist competing with ENV21 in the same regulatory-certified water quality treatment category.
• BioClean (a Forterra brand): Specializes in stormwater treatment devices including hydrodynamic separators and filtration systems (e.g., StormFilter). Directly competes with ENV21's StormPro and V2B1 in NJCAT-equivalent certified stormwater quality markets for municipal and commercial applications.
• Hydro International: UK-based specialist in stormwater treatment technologies including hydrodynamic separators and filtration systems (e.g., First Defense, Downstream Defender). Direct competitor to ENV21's StormPro and V2B1 with similar regulatory certifications and overlapping municipal and commercial target customers.
