     NWTS strives to be the best at what we do. We've fine tuned our methods over the years to repair your water filters as fast and as efficiently as possible, saving you money in the long run. When we do a job, we do it the right way.

​     NWTS has helped many water treatment plants in and around the United States, including the following:

     National Water Treatment Services was started and has been in operation in one way or another since the mid 1980's. In 2007 the company was purchased by Bob and Julie Renner, who have since transformed it into one of the leaders in repairing and maintaining water treatment equipment as NWTS.

     Bob, who has been working with the company since 1991, also has experience in water testing and analyzation, a skill he learned through positions held at the USGS. Julie and Bob currently run the business with the help of their two sons, Eric and Brayden, out of Bismarck, ND.
