Stormwater Management


Local Experience, Customized Solutions


At Woith Engineering, we provide strategic, cost effective stormwater management solutions tailored to the specific needs of each project. We understand that each project brings its own unique set of challenges and design criteria – thus, there is no one-size-fits-all approach to management of stormwater. Our local experience in Great Falls, Missoula, and throughout Western Montana allows us to partner with you to develop customized stormwater infrastructure plans, extend the useful life of systems, lower operating and maintenance costs; all while meeting local regulatory requirements for flood control and water quality standards.

Clean Water for the Future


With recent advances in stormwater management technology and new environmental concerns emerging daily, we recognize that creating and sustaining both our natural and built environments is of paramount importance. At Woith Engineering, we have experience in the design of a wide range of stormwater treatment practices, including bioretention basins, permeable pavement systems, extended detention basins, biofiltration swales, and infiltration basins. In addition, we can work with project owners and suppliers to design and select proprietary treatment devices to meet the specific needs of each project.
