Water Resources for San Mateo County Residents
Drop by drop, we can all take part in protecting our waterways.

Pet Waste and Stormwater
Pet waste is a significant source of pollution that can impact both human health and the environment. When pet waste is left on the ground, it can be washed into storm drains by rain or runoff, eventually reaching streams, creeks, the San Francisco Bay, and the Pacific Ocean without any treatment. To prevent stormwater pollution, remember to pick up after your pet and dispose of waste properly in a sealed bag and trash bin.
Join us in our commitment to cleaner communities and healthier waterways. By pledging to scoop the poop, you help prevent pet waste from polluting our environment and protect public health.

Green Infrastructure
Green infrastructure uses natural systems such as vegetation and soil to manage stormwater, reduce runoff, and filter pollutants. If you’re looking to landscape your yard, consider replacing a traditional lawn with a rain garden that incorporates native plants and flowers.

Water Conservation
Conserving water is essential for ensuring clean and reliable water for all residents. Simple water-saving practices can make an impact. Interested in conducting a water audit in your home? The Check-It-Out! Home Energy and Water Saving Toolkit is available for checkout at San Mateo County libraries and includes useful tools such as low-flow showerheads and faucet aerators to help you improve water efficiency.
