Stormwater runoff is precipitation from rain or snowmelt that flows over the ground. As it flows, it can pick up debris, chemicals, dirt, and other pollutants and deposit them into a storm drain system or waterbody.

Anything that enters a storm drain system is discharged untreated into the waterbodies we use for swimming, fishing, and providing drinking water. In Merced, these waters drain directly into Bear Creek, Black Rascal Creek and other natural waterways.

Remember: Only Rain Down the Drain

To keep the stormwater leaving your home or workplace clean, follow these simple guidelines:

Use pesticides and fertilizers sparingly.

Repair auto leaks.

Dispose of household hazardous waste, used auto fluids (antifreeze, oil, etc.). and batteries at designated collection or recycling locations.

Clean up after your pet.

Use a commercial car wash or wash your car on a lawn or other unpaved surface.

Sweep up yard debris rather than hosing down areas. Compost or recycle yard waste when possible.

Clean paint brushes in a sink, not outdoors. Properly dispose of excess paints through a household hazardous waste collection program.

Sweep up and properly dispose of construction debris like concrete or mortar.

Lawn or shrub trimming are not permitted to be blown into public right of ways.
