Water Pollution Control

Our Water Pollution Control department manages the city's Class III Municipal Wastewater Treatment Facility, which is integral to protecting the health and well-being of the community and downstream users.

How to Support Our Stormwater Control Efforts

• Never dump anything down storm drains or in streams.
• Use the least toxic pesticides, follow label instructions, and learn how to prevent pest problems.
• Use fertilizers sparingly and sweep up driveways and sidewalks.
• Disconnect downspouts.
• Compost yard waste.
• Use rain barrels to water plants during dry periods.
• Vegetate bare spots in your yard.
• Take your car to the car wash or wash it on the grass instead of washing it in the driveway.
• Pick up after your pet.
