City of Davis Storm Drain Marking Program

Pollution Prevention Starts with your Help

A Word About Water

What happens to water from rains, lawn watering, or car washing? These waters, referred to as stormw ater or urban runoff, flow into the city’s storm drain system through over 2500 curb side catch basins – small openings that you find along street gutters. These waters move through the system to our rivers, creeks, wetlands, sloughs, the delta and the bay, on their way to the ocean.

Upon entering the catch basins, the runoff is transported via an intricate system of storm drain piping below our streets. Initially, these waters fill the stormwater detention/wildlife ponds. The North Area, West Area, and Core Area ponds are a few that you may have visited. These ponds are landscaped to support an array of wildlife species. From the ponds, water flows through conveyance channels towards the northern and eastern edges of the city.

A large portion of the stormwater that is collected in the city is conveyed to the Davis Wetlands where it’s used to support the wetlands system and all its wild inhabitants

Protect Our Wetlands

It’s important to ensure that the water entering our ponds and wetlands is safe for wildlife. This is why toxic materials may not legally be dumped into curbside catch basins. Water quality is compromised when people dump used motor oil, antifreeze, paint products, pesticides, pet wastes, or other pollutants into catch basins. This in turn threatens the health of wildlife that is dependent on the ponds and wetlands habitat.

The City is, therefore, working to remind everyone about the importance of preventing pollution of our stormwater by installing drain inlet markers:

Helping From Home

Automotive care:

  • Home auto mechanics – when you change your oil, collect used fluids and take to either Davis Waste Removal, 756-4646, or to a Household Hazardous Waste Turn-in Event at the Yolo County Landfill, 666-8729. The Landfill will also take your oil filters.
  • Maintain your vehicle to avoid leaks of oil, antifreeze, or other liquids. Use a drip pan where appropriate.
  • Take your car to a car wash or wash it on your lawn. Use a shut-off nozzle to save water and be sure to pour your soapy water down the sink.
