Tri-County Irrigation

Tri-County Irrigation is Central Illinois’ premier irrigation contractor.  From installation or seasonal startup to repair and maintenance, our 30 years of experience delivers quality and customer satisfaction.


The success of your irrigation system depends largely on the contractor you choose to install it. At Tri-County Irrigation, we use our expertise to design the most efficient and reliable irrigation system for your particular landscape.

Your irrigation system design will make the difference between a system that is reliable and keeps your lawn green and healthy, and one that is troublesome, wastes water and leaves your lawn looking brown and unhealthy. Call TCI Companies, Inc. today to find out how you can get a great looking lawn too!
