The City's storm drain system is designed to prevent floods and only
rain water should flow through them. When water flows out of our yards,
down driveways, out parking lots and into the storm drains, it makes its
way through the environment, untreated. Storm drains are not connected
to the sewer system; instead they drain directly into our waterways. In
Watsonville our storm drains lead to our local wetlands, creeks and the
Pajaro River, which eventually enter the Monterey Bay and wash onto our
beaches.
