What is storm water?
Storm water is rain, snow, hail and sleet. When storm water runoff enters the storm drain system through the gutters outside your homes it goes, untreated, into the waters that we use for swimming, fishing, and other recreational uses.
Storm water can pick up debris and pollutants.
As storm water flows over driveways, lawns, and sidewalks, it picks up debris, chemicals, dirt, and other pollutants. Storm water can flow into a storm sewer system or directly to a lake, stream, river, wetland, or coastal water. The largest source of storm water pollution in Utah results from everyday activities. The most common pollutants are: Trash, Toxins, and Sediment.
Our storm water crews try their best to clean up most of this trash and remove it but it would make things easier and less costly if we all worked together. Remember that “Only Rain Goes Down the Drain.” If you see this debris, clean it up and dispose of it in the trash.
Polluted runoff is the nation’s greatest threat to clean water.
By practicing healthy household habits, homeowners can keep common pollutants like pesticides, per waste grass clippings, and automotive fluids off the ground and out of storm water. Adopt these healthy household habits and help protect lakes, streams, rivers, wetlands and coastal waters. Remember to share the habits with your neighbors!

Storm Water Management Plan
Lehi City adopted a revised storm water management plan in 2018. The purpose of the plan is to limit, to the maximum extent practical, the discharge of pollutants from the Lehi City storm drain system. You can view the current plan at the following link:
