What Norweco does
Norweco, Inc. (Norwalk Wastewater Equipment Company) is a privately held U.S. manufacturer of water and wastewater treatment products, systems, and chemicals, founded in 1906 and headquartered in Norwalk, Ohio. The company designs and produces residential and commercial onsite wastewater treatment systems — most notably the Singulair line (Singulair Green, Singulair TNT, Singulair Model 960, Singulair R3, Singulair Solar, Singulair NPDES) and Hydro-Kinetic line (Hydro-Kinetic Green, Hydro-Kinetic Bio-Film Reactor, Hydro-Kinetic Model 600 FEU) — that use an extended aeration process with proprietary Hydro-Kinetic Bio-Film filtration and attached growth nitrification-denitrification technology. Commercial offerings (Modulair, Travalair) scale from 1,500 to 500,000 gallons per day. The portfolio is complemented by Bio-Dynamic dry chemical tablet feeders, a chemical consumables line (Blue Crystal, Bio-Sanitizer, Bio-Max, Bio-Neutralizer, Phos-4-Fade, Nitro-Buster), and Service Pro control centers for monitoring. NSF Standard 40 and 245 certifications support regulatory acceptance.
The business model combines one-time hardware sales of treatment systems with recurring revenue from chemical consumables and replacement parts. Distribution is anchored by a certified dealer and service provider network across the United States, supplemented by direct enterprise sales (1-800-NORWECO) and a direct-to-customer online store (store.norweco.com). Target customers include homeowners outside municipal sewer reach, light commercial and semi-public operators, engineers specifying municipal projects, and cities seeking phosphorus reduction. Pricing is unit-based and not publicly disclosed; quotes are obtained via direct contact.
In 2025 Norweco began construction on a 25-acre, 500,000-square-foot campus-style expansion in Norwalk via a joint venture with Norwalk Precast Molds, more than doubling its operational footprint. The company is led by President Gregory Graves, who received the NOWRA Richard J. Otis Industry Achievement Award in 2018 and previously served as President of NOWRA. Norweco's leadership was instrumental in advocating for key provisions of the NOWRA Act, signed into federal law via the 2018 America's Infrastructure Act. The company has 51-100 employees and operates as one of The Norwalk Companies.
