Stormwater Management

Stormwater Management

CH2OOSE to keep our water clean!
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.

Wentzville receives an average of 37" of rain annually, creating many millions of gallons of stormwater runoff each year. The volume and speed of runoff can cause flooding and erosion and destroy natural habitat. The Stormwater Management Program is the City of Wentzville's ongoing commitment to manage flood risk and comply with state and federal laws to help improve our community's water quality. Do your part to help keep Wentzville's waterways healthy for people, fish, and wildlife. And remember...only rain should go down storm drains.
