Guidelines for Preventing Storm Water Pollution

Reporting Problems

If you see someone dumping oil, trash, or other pollutants into gutters, storm drains or canals in the City's system, please report the incident to us at 530-661-5962. Note the address and as much pertinent information as possible.

Swimming Pools & Spas

Drain your swimming pool or spa into your sewer clean-out or onto landscaping. Only drain to the gutter if you can verify that the water has been dechlorinated and is free of algae.

Yard Waste

Place yard waste piles in the street only if your green waste cart is full and only in accordance with your green waste program schedule (see Green Waste Schedule & Guidelines (PDF)). Place piles away from curb and drain inlets to allow for free movement of storm water in the gutter.

Landscape Maintenance

Use pesticides and fertilizers sparingly and do not over-water your lawn.

Pet Waste

Dispose of pet waste in the trash - never in yard debris piles or in the storm drain.

Construction Debris

Sweep up and properly dispose of household construction debris such as concrete and mortar.


Wash brooms and tools used for concrete work in a wheelbarrow or tub of water. Let the water evaporate and throw away the concrete waste, or pour the water out on a contained, paved surface where it can dry and be swept up.


Repair auto leaks. Recycle used motor oil (contact Waste Management at 530-662-8748 for container).

Hazardous Waste

Dispose of household hazardous waste, used auto fluids, paint, and batteries at designated hazardous waste collection or recycling locations. Free Household Hazardous Waste Drop-Off Days are held a the Yolo County Central Landfill every Thursday, Friday, and Saturday from 7:30 a.m. to 3:30 p.m.
