Water Quality Management Plan LogoDid you know that overwatering contributes to stormwater pollution? Overwatering washes the chemicals in pesticides and herbicides from your lawn into the street and into the stormdrain. Overwatering also wastes precious water resources. There are several ways that you can stop overwatering and help the environment.

Storm Drain SealTustin has a direct impact on the health of Orange County beaches? Storm drains are designed to remove rain water from the street. Water flowing from your sidewalk goes into a catch basin, flows through the City storm drains, and then ultimately ends up unfiltered in the Pacific Ocean. This is different from our sewer systems which carry water from inside our homes to a wastewater treatment facility.

Therefore Remember that Storm Drains are for Rain...

Recycle WastebasketNot for Litter

Do not throw litter and debris into the street. Trash in the gutter flows directly to local beaches and can clog storm drains causing flooding.

Fertilizer and PesticideNot for Fertilizers or Pesticides

Reduce pesticides and fertilizer use during wet weather. Excessive use of fungicides, insecticides, and fertilizers contribute to storm water pollution with the release of toxic and synthetic chemicals.

Pet WasteNot for Pet Waste

Pick up after your dog. Animal waste left on the ground washes down storm drains and contaminates beaches.

Yard WasteNot for Yard Waste

Bag compost or recycle grass, tree limbs, leaves and other yard waste. Don’t rake, blow, or hose yard waste into the gutter. Soggy yard waste is a major contributor to clogged storm drains, and street and neighborhood flooding.

Used Oil Filter and Automotive FluidsNot for Automotive Fluids (including Used Oil Filters)

Recycle all hazardous waste including motor oil, antifreeze, and radiator fluids, as well as household waste like paint, solvents, and caustic cleaners.

The City of Tustin encourages all its residents to recycle their used motor oil and oil filters to prevent contamination of stormwater.  For a listing of local certified used oil collection sites go to CalRecycle.  Used oil and filters can also be disposed of at hazardous waste collection sites.  To find your nearest hazardous waste collection site go to Orange County Integrated Waste Management Department.

Pesticides are another stormwater contaminant.  Drought tolerant or native vegetation do not require as much water or pesticides, which helps to eliminate a common source of stormwater pollution.  For a listing of drought tolerant plants and possible rebates for water saving strategies go to or
