Be a Part of the Solution to Water Pollution
When you take a shower or wash clothes in your home, the rinse water goes down the drain and into the sewer system to be treated. Outside your home, things are very different. Everything that flows into a storm drain goes untreated directly into our local creeks and ultimately, into the ocean. Our nearby wildlife, plants, and of course, humans, are dependent upon these bodies of water for habitat, livelihood, and recreation. Unfortunately, stormwater and runoff entering our watershed are often polluted by pesticides, fertilizers, litter, pet waste, motor oil, eroded soil, and household chemicals. Stormwater is managed through the implementation of the City’s National Pollutant Discharge Elimination System (NPDES) permit. Below are some resources that describe how you can help prevent stormwater pollution and keep our local creeks healthy and clean.

Business Best Practices
The downloadable brochures listed below describe how you can help to prevent water pollution as a business operating in the City of Gilroy.
Only Rain in the Drain - Report Illicit Discharges
The most important thing to remember about keeping our creeks clean is that only clean rainwater should be in the storm drain system. The storm drain system includes gutters, storm drains, channels, creeks, and streams. Rainwater flows untreated through the local storm drain system to the Pajaro River and eventually drains into Monterey Bay.
If you see anything other than rain entering the storm drain system, including substances that look like water during dry weather, please do your part to protect your community and its resources: call 408-846-0451 immediately.
After you call, the City will observe the illicit discharge and take corrective actions, if needed. Gilroy has adopted a Storm Water Ordinance (Chapter 27C) which provides the authority for the City to enforce water pollution prevention and stop illicit discharges.
Your Home, Your Watershed
A watershed is the system of creeks and rivers that drain a certain area of land when it rains. Did you know that as a resident of Gilroy, you live in the Uvas-Llagas Watershed? That means when it rains, water goes into your gutter, through the storm drains, and empties (untreated) into Uvas or Llagas Creek, Uvas and Llagas Creek carry the City’s rainwater to the Pajaro River which drains into the Monterey Bay. The Uvas-Llagas Watershed is part of the larger Pajaro River Watershed. San Martin, Morgan Hill, and Hollister are also part of the larger Pajaro Watershed.
