What Norwesco does
Norwesco, Inc. is a privately held, Minnesota-based (Mound, MN) industrial manufacturer founded in 1939 and described as North America's leading producer of proprietary rotationally molded polyethylene tanks. The company's core competency is a rotational molding process that yields one-piece, seamless tank constructions with no welds or joints, made from corrosion-resistant, lightweight polyethylene in sizes ranging from 12 gallons to 20,000 gallons. This manufacturing base underwrites three product lines: Liquid Storage Tanks (above-ground storage for fertilizer solutions, agricultural and industrial chemicals, water, liquid feeds, and plant foods), Water & Waste Management Tanks (below-ground septic, cistern, holding, and pump tanks), and a fluid-handling accessories line spanning ball valves, cam-action couplers, bulkhead and Schedule 80 fittings, Y- and T-line strainers, and tank lids.
Norwesco sells exclusively through a multi-vertical distributor network - covering fertilizer dealers, implement dealers, plumbing and water-well wholesalers, lumberyards/building materials distributors, and municipal/government channels - supported by an online distributor locator and an LTL Rate Quote system for registered distributors. End customers span agriculture and farm operations, the chemical industry, municipal and government water/waste applications, residential/homeowners (through plumbing wholesalers and lumberyards), and the plumbing/water-well industry; pricing is not publicly disclosed and is set at the distributor level.
The company holds NSF certification on applicable water tanks (rated 8 lb/gallon for water storage) and complies with the California Supply Chains Act. Its recent strategic activity is concentrated in product launches rather than M&A or geographic expansion, with six product introductions between 2024 and 2026 that extend the portfolio into stainless steel transport tanks, mobile/utility tanks, baffle/anti-slosh accessories, inductor tanks, and cone-bottom support stands. No information on revenue, headcount growth, or ownership structure beyond private-corporate status is publicly available in the supplied data.
