Nelson Irrigation Corporation

What Nelson Irrigation Corporation does

Nelson Irrigation Corporation is a privately held, family-controlled manufacturer of agricultural and industrial irrigation equipment headquartered in Walla Walla, Washington. Founded in 1972 with roots tracing to 1911, the company designs and produces a comprehensive portfolio including Big Gun sprinklers (75–200 Series), Rotator sprinklers (R5–R2000, plus 2025's R7), end-of-pivot products, control valves (800 and 1000 Series), pressure regulators, air control valves, and the Twig wireless automation control system (including the award-winning Twig-V Plus). Differentiated technology centers on the proprietary Rotator drive mechanism — a viscous silicone fluid-controlled, single-moving-part design with 30+ years of field validation — and an extensive global patent portfolio covering US and foreign jurisdictions.

The company sells exclusively through a worldwide network of authorized dealers supported by regional territory representatives covering North America, EMEA, Latin America, Australia/Asia Pacific, and Eurasia, with no direct-to-end-user sales and a quote-based pricing model. Its end customers are commercial agricultural growers (field crops, row crops, orchards, vineyards, nurseries) and industrial users (dust suppression, mining, sports fields, wastewater), with software tools (PivotMapper, IRRICAD, OverlapPro) provided as design and management support. Nelson has won multiple Irrigation Association New Product Awards and AE50 Awards from ASABE, and divested its MP Rotator turf sprinkler business to Hunter Industries in 2007 to focus on agricultural irrigation. The company employs 101–250 people, is wholly family-controlled with no disclosed institutional capital, and has been actively expanding its international sales infrastructure since 2024.

• T-L Irrigation Company: T-L Irrigation manufactures hydrostatically powered center-pivot irrigation systems, competing with Nelson in pivot sprinklers, end-of-pivot products, and agricultural water-application equipment for row-crop and field-crop growers.
• Reinke Manufacturing: Reinke is a direct competitor in center-pivot irrigation equipment, producing pivot sprinklers, end guns, and control systems comparable to Nelson's Rotator, Big Gun, and 800/1000 Series valves for the agricultural irrigation market.

Emerging players

• Rivulis Irrigation: Rivulis is a global micro- and drip-irrigation provider formed from the merger of Netafim/Plastro-related assets. It competes with Nelson in adjacent precision-irrigation segments and serves overlapping agricultural customers seeking efficient water-application solutions.
