History

Founded in 1968 by John A. Heidman, IRRI-TECH has worked on thousands of projects over our 54-year history.

In the 1980s, IRRI-TECH was one of the first irrigation companies in the country to design, install and operate a computerized irrigation control system for a commercial project. This was one of the largest most sophisticated irrigation systems on a single water supply in the world. It is the product of the technical expertise of IRRI-TECH’s staff and the customer working with each other. Due to the emphasis on water conservation, the entire system was computerized and equipped with its own weather station. This computerized system and weather station monitors and adjusts the watering program so well that water consumption was reduced by over 1 million gallons of water per night during the peak watering season.

Over the years, we’ve tackled countless largescale projects using alternative water sources, pumps, and sophisticated control packages. We’ve also successfully completed hundreds of smaller irrigation projects for both residential and commercial clients. We apply the same expertise and quality service to projects of all sizes.
Please see our portfolio of completed projects.

We’re proud to say a significant amount of our business comes through long-term relationships, direct customer referrals, and repeat clients.
