Success Stories

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.

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

I just spoke with Doug Mitchell at Western Fleming WTP regarding our work at the water treatment plant. He is VERY pleased with our work on the installation of their Allen Bradley VFD’s for their high service pumps and highly complementary of our Service staff. This job was a true team effort and he acknowledged it was a very difficult scenario we stepped into and had to navigate. He said his high service pumps are working exceptionally well, the best they have ever operated. He thoroughly appreciated our due diligence and meticulous attention to detail. Although this project took longer than anticipated, I believe this gave us another feather in our cap and a future long standing relationship with Doug and Western Fleming. I would like to personally thank our Lexington service staff and Randy for a phenomenal job of installation and trouble shooting, and Jon K for working around scheduling conflicts and aiding towards the completion of this project. I feel we really took a lot away from this project and can build upon the acquired knowledge to attribute it to future opportunities down the pipeline. Thanks Jon, Brian, Sandy, Marty and Randy!

~ Jeff Morrison, C.I. Thornburg Company

I spoke this morning to Danny Layton, the new water superintendent at the City of Kingwood, WV, and he wanted me to relay a heart-felt “Thank You” to Brad Ball for his willingness to travel 2-1/2 hours on a Friday evening to deliver a new level transducer in order for them to control their clearwell over the weekend.

~ Randy Clark, C.I. Thornburg Company

We at the Carlisle Water Treatment Plant would like to thank your company but in particular Sandy Parr, Brian and John for all of the assistance and hard work and dedication they put in on fixing our river pump. Their tireless efforts are the reason our customers have safe potable water to drink today. Again we really appreciate the efforts of everyone in your company.

~Gary  Osborne and the Water Plant Staff

I have been the Chief Operator for Kenova Municipal Water for the past 7 years. When I took over the water system here, we were in serious need of improvements in almost every aspect of our operations. During this time I have worked with several companies to help meet the needs of my water system. The one constant has been the presence of The C.I. Thornburg Co., Inc.  C.I. Thornburg has provided me with not only the materials and treatment chemicals needed to operate a system properly, but they also provided me with industry knowledge and support. The professionals at CITCO have a plethora of experience in every facet of this industry ranging from but not limited to water treatment plant optimization, leak detection, metering, valves, telecommunications, consulting, etc…
The Kenova Municipal Water System is the recent recipient of 3 “Drinking Water Performance Gold Awards” for being The Surface Water System of the Year, Most Improved Water System, and for being an Optimized Water Treatment Plant. I owe a great deal of credit to The C.I. Thornburg Company for our successes. Their dedication to us and our system has been a tremendous blessing and I know that without the great teamwork with CITCO, these awards would be nearly unattainable for us.  It is a great pleasure working with CITCO and a great feeling knowing they are always there to help.”

~Larry Smith, Chief Operator City of Kenova
