Started the Company

Seven decades ago Richard Diekman started his lawn irrigation company. Richard’s son joined the team, and from that point we began to grow fast as a family owned and operated business.

Second Location

These last years we grew very quickly, so 1997 was the year we opened a second location. The new location started with five new irrigation technicians.

New Generation

July of 2021 the Founder and proud Father, Richard, passed away leaving the keys of operation to his son, Timothy Diekman, Director of Arizona Irrigation Company.
