Stormwater in the City of Des Moines is managed by the Clean Water Program. Altough it is the responsibility of the Clean Water Program to manage the city's stormwater, residents can also assist in many ways.
Ways to Reduce Stormwater Runoff and Improve Storwmater Runoff Quality
- Redirect Roof Drains: Make sure the drains coming off your roof are directed into nearby gardens or other vegetated areas, not the sanitary sewer.
- Use Phosphorous-Free Fertilizer: Purchasing and using phosphorus-free fertilizer helps reduce algae blooms as it is not a needed nutrient for central Iowa lawns. Phosphorus is the middle number displayed on fertilizer bags. (For example, 20-0-20).
- Clean Up Pet Waste: Clean up pet waste to prevent excess nutrients and harmful bacteria from entering water bodies.
- Use Best Management Practices: The City of Des Moines will reimburse property owners 50% of the cost (up to $2,000) for qualified work that reduces stormwater runoff.
The City of Des Moines also offers the Stormwater Best Management Practices Program, which provides recommendations residents can implement to help enhance the water quality of stormwater runoff and/or decrease the amount of stormwater runoff that enters the stormwater drainage system.
