75 Years Serving You

In any drainage plan, it is essential to manage the water level to protect water quality or reduce the risk of flooding. It is also important to find the right manufacturer to provide you with high-quality water control structures for your properties.


At Wisconsin Flowgate, we have proven to consistently deliver top-grade products to our clients since 1955. We take great pride in having more than 75 years of combined experience in the industry. Our company constantly strives to fulfill the needs of each of our customers.

In addition to our custom structures, we wholesale and distribute drainage products within the residential, commercial, agricultural, and industrial markets. From drain tile to culverts; PVC to erosion control; our ever expanding product list is sure to provide what you need for your next project.
