About Lad Irrigation


Lad Irrigation Corporation began in 1957 with three employees installing and servicing irrigation pumps in the Moses Lake region.  The company was incorporated in 1967. Headquartered in Moses Lake, with branches in nearby Othello, George, and Royal City, Lad Irrigation has steadily grown to service the Columbia Basin and surrounding areas of eastern and central Washington with 70 employees.

In January, 1995, founders and owners Arlie and Aurora Updegrave, sold 51% of the company to the employees, by forming an Employee Stock Ownership Plan, or ESOP. In April 2007, the employees purchased the remaining 49% of the company.


We are focused on improving irrigation–conserving water, conserving energy and increasing overall efficiency. We believe that irrigation is essential to sustaining and enhancing the standard of living of a growing world population.  In the future, water will become an increasingly precious commodity, and conservation efforts must rise to meet increasing demand.  Doing more with less water will continue to be a challenge, and Lad Irrigation has the product line and expertise to meet it head-on.

Company Vision

We are committed to excellent customer service and building long-term relationships, while promoting a workplace that encourages excellence, knowledge, integrity, and innovation in our employees. From strategic locations, we will provide our clientele superior, efficient, and affordable solutions for their irrigation and pumping needs.

Each of of our irrigation, pump, and water system designs are unique to the needs of the customer and the land it serves.  We understand the importance of your investment, and our success depends on your satisfaction.
