Keep It Clean

Simple steps you can take at home to  prevent water pollution .

Take a Tour

Watershed Signage

Signage installed at Griggs, O'Shaughnessy & Hoover Reservoirs invites park visitors to  take a self-guided tour along the shoreline & learn about the green infrastructure installed there.

Rain gardens, porous pavement & more can improve the quality of storm water entering the reservoirs that supply our drinking water.

Make Smart Choices Maintaining Cars & Driveways

Maintain vehicles to prevent leaking fluids from washing into the curb and storm drains - and ultimately into the river with stormwater.

Absorb leaks on the driveway with sand or cat litter, then sweep up and place in the trash.

Wash Your Car Responsibly
If washing at home, do so over gravel or in the yard to avoid soapy runoff from flowing into the curb and entering the storm drains. Better yet, go to a commercial car wash when possible - they are required to dispose of the water through the sanitary sewer system, where it will be treated.

Sweep debris from sidewalks and driveways instead of washing it away with water.

Consider Pervious (porous) Pavement 
Pervious pavement provides a hard surface while allowing water to filter through and reach the underlying soil where pollutants can filter out naturally. Benefits include: improves water quality, melts snow & drains faster, recharges groundwater, lessens downstream flooding and stream bank erosion. Learn more...
