Stormwater Management Program

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.

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.

2013-2018 Stormwater Management Plan 

The City of Wentzville is permitted under federal and state regulations for stormwater disccharges.  The 2013-2018 Stormwater Management Plan and 2015 Annual Report is available here.   Please share any comments using the Contact Us form. 

Wentzville Middle joins in to clean up & educate 

This year marks the 12th anniversary of the GM GREEN  partnership with schools, GM, and the City of Wentzville. Last school year, students investigated issues and put their education into practice by tackling projects to clean up the community. To decrease litter and improve water resources, sixth-graders at Wentzville Middle recorded a video with Alderman Wright and launched Toss 10 on Tuesday to increase awareness and challenge the public to pick up 10 pieces of trash on any given Tuesday.  Students conducted a campus-wide litter pickup, made wildlife habitat improvements and planted native landscaping in rain gardens at Hearland Park.

The City dedicated a monument in their honor at Heartland Park to highlight the student's hard work and accomplishments to make Wentzville a more beautiful place to live, now and in the future.

Dry Branch Watershed: Clear Stormwater & Green Parks

Wentzville was awarded $748,015 from Region VII, US EPA, through Missouri Department of Natural Resources under Section 319 of the Clean Water Act.  The project addresses nonpoint source pollution by identifying pollutants, and prioritizing and constructing solutions for our community.  The Dry Branch Watershed includes areas predominantly north of I-70 that drain to McCoy creek.  Learn more.

Mission: Clean Stream Success!

We want to extend a sincere thanks to our volunteers' time and hard work to beautify our community at this year's cleanup.  In Wentzville, 158 participants worked at six sites in Wentzville.  Some commented, "We had no idea the creek was even there."     

Wentzville Streams Named

The U.S. Board on Geographic Names approved nine names for streams submitted in the City's Stream Naming Contest last summer.  This was part of the City's 319 Grant project to increase awareness of water quality and water resources.  Press Release
