Ottenweller Contracting is now one of the Midwest's premier water and wastewater treatment plant contractors. We have decades of experience in both municipal and industrial water treatment contracts from smaller expansions and modifications to complete new facility construction. In addition to treatment plants, our team are experts in lift stations, process piping, and mechanical systems related to water and wastewater treatment.

​

The successful completion of a water/wastewater treatment project requires highly collaborative, in-depth planning throughout the design and construction process. Ottenweller has a proven history of success in maintaining the highest safety and quality standards, as well as permitting and approval requirements. These factors must all be met to ensure the engineering and construction proceed as planned, on schedule and within budget.
