Brands We Carry


The Town of Harrisville and the Hughes River Water Board have had a wonderful working relationship with C.I. Thornburg over the years. Whenever the Town has had an emergency, they have bent over backwards to get us the necessary tools, equipment or manpower to get things back in working order.

~ Mayor Alan Haught, Harrisville, WV

Knowing our predicament C.I. Thornburg Company agreed to rush the build to have this system in place in 4 weeks. When all was said and done, although not complete, this system was operational even sooner than projected. For that we are grateful to C.I. Thornburg Company for their expertise, diligence and commitment throughout this process.

~ Mt. Sterling Water and Sewer

We would like you to know how much we appreciate your prompt response to our problem at the pump station which services four of our residents. Thank you for providing us with the excellent service and the very courteous and efficient personnel doing the work.

~ Wyngate Condominium Association

And I want to extend our thanks to your staff for helping make everything go smoothly. Steve did a great job getting the deliveries arranged. Then the driver phoned the technicians at both sites notifying them of expected delivery time, which meant my staff didn’t have to sit around and wait. I appreciate the great customer service we received from your company.

~ Dianna Wright, WV Department Of Natural Resources

The installation was completed, calibrated and started-up on-time and within budget. It was a pleasure to work with the “Can do” CITCO crew to install these needed improvements. Thanks to C.I. Thornburg Company for a job very well done!

~ City of Thomas WWTP

In 2014 our district began a search for a new telemetry system. I contacted CI Thornburg and requested information about the components of their systems and asked to visit their facility. They invited me to their facility and showed me what they had to offer. They not only met my expectations, they exceeded them. After agreeing on a price and product, installation was timely. All staff were professional, courteous, and willing to answer questions. Now that time has passed, we continue to be satisfied with the product. Special Thanks to Sam Warnock, Control Systems Manager – for making this a seamless transaction.

~ Jon Blalock – Superintendent, South Hopkins Water District

The Village of Middleport and I would like to thank you for all of your dedication and hard work. First, for several years now you have provided our water and wastewater treatment chemicals. On the week before Labor Day last year we had an oversight of ordering chemicals at the beginning of the week. On that Friday I called late in the afternoon to try to get a delivery knowing we could not make it until the following week on chemicals. You delivered late that afternoon so we could stay in compliance at our WWTP. I know the driver had to been staying late that evening to get this accomplished. Second, Middleport decided to pursue a radio read water metering system. This was a huge decision on my part as well as the Mayor and Council. I want to thank everybody involved with this project. John, Rod and Jeremy you went out of your way to show us the operation and analytics of the Sensus metering system. You allowed us to visit several municipalities where this system was installed making sure we had all the knowledge and feedback we needed in making our decision. Finally, your service has been outstanding. The sales people in the field talk on a level that you can relate to and trust. It is never with the normal “sales pitches” but the facts and like I am talking to my neighbor or next of kin on my front porch.

~ Joe Woodall, Middleport Village Administrator
