Water Use Guidelines

For the week of August 8 - August 14, precipitation was 0.23 inches and turf grass in the area used 1.21 inches of moisture, according to WSU AgWeathernet data.  Home irrigators should have run spray type sprinklers 3 times for 14 minutes and rotor type sprinklers 3 times for 49 minutes this week.  Calculations are based on average precipitation rates, please adjust for local conditions.

Yard care and water savings Tip

  • For hanging baskets, planters and pots, place ice cubes under the moss or dirt to give your plants a cool drink of water and help eliminate water overflow.

  • Watch for weed growth near driveways and walkways. Weeds gain a foothold in areas where high temperatures can damage cool-season grass, such as along the edges of driveways, walkways, and patios (the hardscape raises the temperature of the surrounding lawn). Pull out any weeds that emerge in these areas immediately so that seeds do not sprout and spread throughout the yard.

  • Inspect your irrigation system while it is operating once a month – look for leaks or heads that are plugged or misdirected.

Additional Water Conservation Information

A dripping leak consumes:  15 gallons per day - 450 gallons per month = $1.02 per month
