History

In 1989, Cal-West Rain was formed because a San Joaquin Valley farming company saw the need to have both an irrigation AND a pump company as a single supplier. Prior to that time, most operated as separate entities, irrigation or pumps, not both under one roof.

Thinking the idea had real merit, the grower approached our co-founders Larry Isheim and Jim Martin to help start the company. Larry’s expertise in design, installation and service of agricultural irrigation systems, combined with Jim’s expertise in pumps and well development.

After more than three decades, the founding formula for Cal-West Rain still remains, providing high-quality irrigation design and installation as well as complete service in pump design and installation from a single source. Established in the fall of 1989 with one office in Kerman, Cal-West Rain has added additional locations in Paso Robles, Hanford and Bakersfield. We feel our growth and success is driven by our Values, Vision and Mission.

From one of the largest well developing engines in the country to tiny drip emitters and advanced monitoring and control systems, Cal-West Rain designs, installs and services it all. Additionally, as a member of the Irrigation Association®, Cal-West Rain maintains a staff of Certified Irrigation Designers.

Jim Martin has been in the pump business for over 50 years. Jim has supported Fresno State by being a past president of Ag-One, and a fundraiser for the Bulldog Foundation. He is also an alumnus of Fresno State and Leadership Fresno. He is a former member of the Fresno County Grand Jury as well as a past board member of Hinds Hospice.

Larry Isheim has been in the irrigation business for more than 50 years, six of which were spent designing, installing and managing irrigation systems for a large diversified farming company specializing in tree fruit and vineyards. Larry is a Certified Irrigation Designer in Drip and Micro and has served on the advisory board of the Center for Irrigation Technology at California State University, Fresno.
