Pacific Southwest Irrigation

What Pacific Southwest Irrigation does

Pacific Southwest Irrigation Corp. (PSWI) is a privately held, full-service agricultural irrigation company headquartered in Stockton, California, founded in 2003 by Jim Clare, Gary Simas, and Sonny Lucchesi. The company designs, supplies, installs, maintains, and repairs irrigation equipment for farmers, food processors, dairy operations, and turf and sod producers throughout California's Central Valley, operating five retail/parts store locations spanning Yolo to Kern Counties with a rolling-store delivery service across the Northern San Joaquin and Southern Sacramento Valleys. Customers are primarily SMB agricultural producers in row crops, trees, vines, forage crops, and dairy/livestock operations.

The company's product portfolio spans drip irrigation, portable and permanent sprinkler systems, pump stations (electric, diesel, PTO), surface irrigation, center pivots and linear moves, filtration systems, and a wide inventory of PVC, HDPE, MDPE, and aluminum pipe and fittings. Proprietary technology includes the Certa-Lok portable irrigation system and the Certa-Set Yellowmine PVC sprinkler system, both developed and patented by CEO Jim Clare (four patents in total covering the Certa-Lok coupler, mechanization, and system). PSWI also carries and integrates third-party OEM product lines including Nelson Irrigation, Netafim, Toro, Rivulis, Irritec, and Lindsay Zimmatic.

PSWI generates revenue through a hybrid equipment-plus-services model: one-time equipment sales, professional services (design, engineering, installation, maintenance, pump and electrical), equipment rentals, parts and counter sales, and automation systems. Go-to-market is sales-led, with fieldmen serving as both consultative designers and dedicated project point-of-contact through completion; consultation and irrigation design are provided free of charge. Pricing is quote-based and not publicly disclosed. The company has grown to 101-250 employees across its five locations, holds California General Engineering Contractor License #835462, and has no disclosed external investors, venture capital, or private equity involvement.

Broad incumbents

• Jain Irrigation Systems:
• Netafim USA: Netafim is the global leader in drip irrigation and a core OEM whose products PSWI distributes; it also sells directly to large growers, making it both a supplier and a partial competitor in drip system design and supply.
• Valmont Industries (Valley Irrigation): Valmont owns Valley Irrigation, the largest US pivot manufacturer, directly competing with PSWI in supplying and servicing center-pivot systems for large-acreage Central Valley farms.
• Nelson Irrigation Corporation: Nelson Irrigation manufactures sprinklers and control valves and co-developed the Windfighter sprinkler and MRDC check valve used in PSWI's Certa-Set system, making it both a partner and adjacent competitor in sprinkler hardware.

• Toro Company (Irrigation Division): Toro is a major manufacturer of micro-sprinklers, drip, and turf irrigation equipment that PSWI resells; Toro's irrigation division targets overlapping ag and commercial customers, particularly in pump stations and micro-irrigation.
• Lindsay Corporation (Zimmatic): Lindsay is a global manufacturer of center-pivot and lateral-move irrigation systems (Zimmatic) that PSWI distributes and services; both serve the same Central Valley grower base for mechanized irrigation equipment.

Emerging players

• AquaSpy: AquaSpy provides soil-moisture and crop-sensor technology for precision irrigation, overlapping with PSWI's soil-moisture monitoring and fertigation automation offering for Central Valley growers.
• HydroPoint Data Systems: HydroPoint provides smart irrigation controls and soil/weather-based automation; it competes with PSWI's automation and controls line in delivering water-saving precision irrigation technology to commercial ag and landscape customers.
