When it rains, stormwater washes over the ground, picking up a variety of pollutants, such as oil, pesticides, metals, and soil. To prevent flooding and safety issues, stormwater travels through the City's storm drain system and is discharged untreated into nearby lakes, streams, and rivers - the ultimate source of our drinking water.

The Stormwater Management Program is the City of Wentzville's ongoing commitment to meet state and federal laws and help improve our community's water quality. All people and property have the ability to influence, and be influenced by, water pollution. Do your part to help keep Wentzville's waterways healthy for people, fish, and wildlife. And remember...only rain down the storm drain!
