Conservation Tips

Since the average person uses up to 100 gallons of water per day, even the smallest effort to conserve water will go a long way toward preserving our most precious natural resource for use by future generations. These tips may be helpful.

Indoor Water Conservation

Save Water Outdoors


  • More modern washing machines require only about 23 gallons of water per load, compared to their older counterparts, which can use up to 41 gallons.

  • Newer dishwashers are equipped with more wash cycle options that help reduce water use.

  • Run the dishwasher and washing machine only when loads are full to conserve water and save on electricity.

  • Place a pitcher of tap water in the refrigerator to eliminate the need to run the faucet for a cool drink. Leave it uncovered so chlorine can dissipate.

  • Turn off the tap while brushing your teeth.

  • Insulate all water pipes located along outside walls and in unheated areas such as garages, pantries and cabinets -- paying special attention to the cooler north side of the house.

  • If you go on a winter vacation, never shut off your heat completely to avoid broken water pipes. Have someone periodically check on the house.

  • Defrost frozen water pipes slowly by applying heat from a portable hair dryer.

  • Limit your shower to five minutes.

  • Thaw frozen foods in the refrigerator instead of using running water.

  • Don’t irrigate during the heat of the day. See Nassau County Lawn Watering Regulations for more detailed instructions.

  • Water deeply to encourage roots to grow downward. Sprinkling lightly promotes shallow roots and weakened plants or grass blades that are more vulnerable to drying from the sun and disease.

  • Employ the “Cycle & Soak” method to minimize runoff and promote deep saturation. For example, instead of watering each zone for 30 minutes, set the timer to operate the irrigation system for two cycles of 10 minutes, giving the water ample time to soak into the soil between cycles.

  • Redirect sprinkler heads that are watering anything other than the landscaping.

  • Utilize a slow-drip irrigation system in your garden beds.

  • Install spring-loaded shutoff nozzles on all garden hoses.

  • Use a broom instead of a hose to clean sidewalks and driveways.

  • Prior to winter, use compressed air (no chemicals allowed) to drain underground sprinkler systems.

  • Before the frost sets in, disconnect hoses from water spigots, drain the hoses and turn off the outside water flow from inside of the house.


  • The Locust Valley Water District recommends the installation of internet-based Smart Controllers to new or existing irrigation systems.

  • On Long Island, only one to two inches of water are needed per week (including rain) to encourage healthy growth.

  • Keeping the length of your lawn at 3 inches reduces evaporation, improves root growth and minimizes weeds.

  • Leave the clippings on the lawn to improve water retention and help the grass grow thicker.

  • Choose landscaping that require less water such as forsythia, lilacs, pines, daylilies, marigolds, lavender, zinnias and African daisies.

  • Maintain a compost pile and add it to your garden, along with wood chips or peat moss to boost water retention.


  • Keep your swimming pool level low to minimize splashing.

  • Cover pools and hot tubs when not in use to reduce evaporation.

  • Periodically check underground sprinklers, pools and spas for leaks and repair them immediately.
