Pollution Prevention for Home Owners

Although Surprise on average receives less than 9 inches of rainfall a year, untreated storm water runoff can transport pollutants to our drinking water sources if we are not careful. Do your part to protect our drinking water by following some of the following simple and easy steps to prevent storm water pollution around your home.

Instructions for draining residential swimming pools

Draining Swimming Pool
  • Do not drain your pool water into the street, alleyway or other right of way. Use caution when discharging to your landscaping to not water the same area repeatedly and to not encroach on other private property. If the land surface is not large enough to backwash or drain your pool safely, contact the water services department for guidance on how to properly drain the water into your sewer cleanout to avoid erosion of your or your neighboring properties.

Fact Sheet on Stormwater Pollution Prevention

Outdoor Washing

Outdoor Washing
  • Use a broom and not a hose to clean your driveway and other paved outdoor surfaces. This not only conserves water, but saves you money on the water bill and prevents dirt and debris from entering the storm water system.
  • Wash your car on grassy or gravel surfaces to keep the excess wash water from flowing into the street and entering the storm water system. Never allow detergents, degreasers or solvents to enter the storm water system.

Automotive Maintenance

Did you know that just one quart of oil can contaminate 250,000 gallons of water?
Automotive Maintenance
  • Many automotive supply and maintenance locations provide disposal of used motor oil free of charge.
  • Keep your vehicle free of leaks, and place a drip pan or adsorbent material beneath any leaks until they can be fixed.
  • Properly dispose of other automotive waste including engine coolant, car batteries, tires and brake pads.

Household Hazardous Wastes

Many common household and automotive products can be hazardous to the environment if not disposed of properly.

The following products should never be disposed of in the storm water system, a landfill through your normal garbage collection, or poured down the drain:
Household Hazardous Wastes
  • Cleaning products: multipurpose cleaners, oven cleaner; floor cleansers and waxes; furniture polish; drain cleaner; carpet cleaner and spot remover products
  • Car care and maintenance: motor oil; battery acid; gasoline; car cleaner and wax; engine cleaner and degreasers; radiator flushing products and antifreeze/coolant; rust preventative products
  • Home improvement products: paints; wood preservatives; strippers; brush cleaners and solvents
  • Other products labeled toxic, flammable, or corrosive; or those containing lye, phenols, petroleum distillates or trichlorobenzene
For more information on Hazardous Waste Disposal Event dates and times please call the Surprise Public Works Department at 623.222.6000, or visit the hazardous material collection Web page.


Pet Waste
Pet waste carries diseases and harmful bacteria. Uncontained pet waste can mix with rainwater and cause storm water pollution, posing a health risk to people and other animals.

Please be mindful of our environment and pick up after your pet. And remember it is the law! (Surprise City Code 6.04.170)


Recycling reduces storm water pollution by keeping these materials not only out of our storm water structures, but also out of our trash and landfills. Curbside recycling is available to single-family residences currently being serviced by the Surprise Public Works Department.
