Two brothers started it. The next generation carries it forward

Two brothers, Dan and Dave, started DDM Irrigation in 1987 out of Marion, Iowa. What began as a single truck putting in residential sprinkler systems has grown into a full-service irrigation shop covering twelve eastern Iowa counties. Now Dave's son Josh is taking over the company, keeping the work and ownership in the family for another generation.

The shop hasn't moved. 640 51st Street in Marion is where the trucks still roll out from every morning. Design, installation, repair, backflow testing, and seasonal service are all handled by the same crew, out of the same building. Josh grew up around the company his father and uncle built, and he is carrying that practical, hands-on approach forward.

Six of us are state-certified backflow test technicians. Every system we install ships with a 1-year warranty that includes the first fall winterization and the first spring start-up. We spec Hunter parts because we can still get replacement heads for them ten years later.
