In 1979, M.E. Simpson Co., Inc. was formed to provide 'Technical Services' to Municipal and Private Water Utilities in the Midwest and other areas of the country in the areas of Water Meter Evaluation and Maintenance, Water Distribution System Leak Surveys, Water Distribution System Valve Location and Exercising and Cross Connection Control Programs. Our purpose was to take advantage of a lack of expertise in this field and to fill this void with qualified people using the best equipment.

M.E. Simpson Co., Inc. was founded by Marvin E. Simpson who had spent the twenty-four years prior to 1979 working within the water works industry for a few major manufacturers of piping, valves, and water meters. The company began operations in Rochester, Indiana and moved the corporate headquarters to Valparaiso, Indiana in 1988. In 1989 the Indiana Section of the American Water Works Association honored Marvin with the “Water Wheel Award” for his outstanding service to his profession. In 1995 Marvin was honored as a lifetime Member of the American Water Works Association.

M.E. Simpson Co., Inc. is proud of the work performed and the maintenance programs we have developed using the latest technology to meet the needs of our customer the Water Works Industry. We have played an important role in educating utilities about the need for and efficiency of annual maintenance programs; including the development of Polcon Pro-Valve®, Pro-Hydrant®, Pro-Smoke™, Pro-Manhole™, and Pro-Sewer™. We are also very proud of the continuing development and manufacturing of the Polcon® Flow Monitoring Equipment. We have moved beyond the competition in flow / pressure recording, computerization and record management.

M.E. Simpson Co., Inc. offers these technical services to water utilities because many lack the manpower, equipment, and/or expertise to perform what is required to consistently supply not only safe, pure, potable drinking water, but a financially sound water system that operates to conserve our most precious resource - WATER
