Stormwater Management

Keeping our Waterways Clean

Making a few changes in our daily lives can significantly reduce the number of pollutants we contribute to stormwater runoff. If you have time please check out for more information on stormwater quality.

Here are some everyday tips that can help in keeping our waterways clean:

  • If needed, use fertilizers and pesticides per the manufacturer’s recommendations.

  • When draining a pool be sure to check that the discharge water has a PH in the range between 6.5 and 8.5. Try to ensure that the backwash does not cause any problems.

  • Consider adding a rain garden or rain barrel to your summer yard projects.

  • If you have pets, remember to clean up after them and dispose of the waste properly.

  • Try to do some plantings of trees, shrubs or ornamentals to increase the green space on your property and help retain stormwater runoff. Native plants work best.

  • If you have a septic tank and have not checked it recently you should check it once a year

Just a reminder, if you see any suspicious dumping of solids, liquids or debris into the storm sewers or waterways within the City of Weldon Spring, please contact the City. You may contact either:
