Water Conservation

Lawn Watering Tips

  • Water in the early morning or evening. If you sprinkle your lawn under the hot sun, you'll lose as much as 30 percent of your water to evaporation.
  • Lawns can only absorb water so fast. It's better to water your lawn for three 10 minute sessions-with each session a half-hour apart than it is to water steadily for 30 minutes and cause run-off.
  • Landscaping that stresses, proper soil preparation, efficient irrigation and the use of water stingy plants means less maintenance and lower water usage.
  • Keep grass at least two inches high to shade roots and hold moisture.
  • Use mulch around plants to reduce evaporation and promote growth.
  • Water trees slowly, deeply and infrequently to encourage deep rooting.

Inside Tips

  • Dripping faucets and leaky toilets account for a large portion of home water waste.
  • Bathing is the second highest use of indoor water, a five minute shower is all that is needed.
  • The toilet is a big guzzler of indoor water. Installing an ultra-low flow (1.6 gal/flush) toilet is an excellent way of reducing flows.
  • Install low flow (2.2 glas/minute) aerators on bathroom and kitchen faucets.
  • Run the dishwasher and washing machine only when they are full.
  • Keep a pitcher of drinking water in the refrigerator.

Outdoor Tips

  • Use a broom to clean the driveway.
  • Adjust your sprinklers so that the lawn is watered but not the driveway or the house.
  • When washing the car use biodegradable soap and water from a bucket of hose with a shut-off nozzle.
