I am expressing my recommendation concerning ISI’s work installing a water distribution system for Decatur County Rural Water Corp. The Installation of over 50+ miles of new water lines started about a year ago and are presently finishing installing water meters and doing finish grading. I would highly recommend this company and its personnel to any water corporation.

I want to thank you and your people for the incredible performance on our 1999 water main reconstruction project. In all my years serving in a public water supply system, I’ve rarely seen an outfit so competent in all areas. We consider this reconstruction project one of our great successes in recent years.
