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.

Prepare for Cold Weather & Freezing Temps

  • Prepare for Cold Weather & Freezing TempsCaulk around pipes where they enter the house and close all foundation vents.

  • Insulate outside spigots, or shut them off from inside the house and drain them.

  • Pipe InsulationWrap all pipes located in unheated areas. Use insulating tape or molded pipe covering (photo) to wrap the entire length of exposed pipe. Check your local hardware or discount store for supplies.

  • ShutOff ValveLocate and mark your main control valve and show everyone in the house how to turn off the water in an emergency. The main valve (right) is located next to the water meter (above right), which is typically in a basement or wherever the furnace and hot water heater are located.

  • During periods with below freezing temperatures, open cupboard doors in the kitchen and bathroom to allow heat to reach areas where pipes come in contact with outside walls. Place a light near the water meter to keep the area warm.
