Water Facts

Water during the cool parts of the day. Early morning is better than dusk since it helps prevent the growth of fungus.

Don’t water the lawn on windy days. There’s too much evaporation.

Cut down watering on cool and overcast days and don’t water in the rain. Adjust or deactivate automatic sprinklers.

Set lawn mower blades one notch higher. Longer grass means less evaporation.

Have an evaporative air conditioner? Direct the water drain line to a flower bed, tree base, or lawn.

When taking your car to a car wash—a good idea for saving water—be sure it’s one of the many that recycles its wash water.

Dispose of hazardous materials properly! One quart of oil can contaminate 250,000 gallons of water, effectively eliminating that much water from our water supply. Contact your city or county for proper waste disposal options. And don’t flush prescription medications!

Water conservation comes naturally when everyone in the family is aware of its importance, and parents take the time to teach children some of the simple water-saving methods around the home which can make a big difference.


The benefits of HyroKnot self-resetting shut-off valves go beyond the size of your own water bill:

  • Landscaping repairs are minimized
  • Water run-off and recapture costs are reduced for local government agencies
  • Water treatment plant costs for local governments are reduced
  • Depletion of area/regional aquifers is slowed
  • Water costs for everyone are kept down


A single damaged or missing sprinkler head can waste up to 750 gallons of water per hour of operation. If left unrepaired, just one month of typical watering cycles will waste thousands of gallons. The HydroKnot automatically activates when water flow exceeds six gallons per minute (GPM).

It automatically resets at the end of each zone’s watering cycle, lowering system water use by up to 35% and thereby lowering your bills.

It eliminates potential soil erosion, building code violations, flood damage and the risk of water fines. Think of it as a long-term, mechanical “insurance policy.”


The aggregate loss of wasted water from broken sprinklers each year is staggering:

  • A one-half inch sprinkler pipe will flow 13-16 gallons per minute (GPM) when broken
  • Unrepaired, three to 10,000 gallons per system will be lost
  • Up to two million gallons per typical suburb or town may go to waste
  • A large city can lose up to 50 million gallons per one million residents
  • Nationally, 18 billion gallons are wasted, enough to fill the Great Salt Lake in Utah twice
