How to conserve water

  • Don’t pour water down the drain. Instead, use it to water your plants or garden
  • Fix dripping faucets, one drop per second wastes 2700 gallons of water per year
  • Take shorter showers and turn off the water while you lather up
  • Turn off the water while brushing your teeth or washing your face
  • When hand-washing dishes, use two containers-one with soapy water for washing and the other with plain water for rinsing
  • Don’t water your lawn too much. Grass only needs to be watered about once a week in the summer. Lawns can go two weeks without water after a heavy rain
