Facts and tips on water usage and conservation are presented weekly by the City of Walla Walla, in partnership with Walla Walla Community College and the Union-Bulletin.
Precipitation and moisture
Last July: .02 inches
This July so far: 0.00 inches
Soil moisture content: Normal

Water use guidelines
For the week of June 26 – July 2, precipitation was 0.22 inches and turf grass in the area used 1.72 inches of moisture, according to WSU AgWeathernet data. Home irrigators should have run spray type sprinklers four times for 15 minutes and rotor type sprinklers four times for 57 minutes this week. Calculations are based on average precipitation rates, so adjust for local conditions.
Yard care and water savings tips
Place children’s water toys on any dry spots in your lawn.
Keep a bottle of drinking water in the fridge. Running tap water to cool it off for drinking water is wasteful. Store drinking water in the fridge in a safe drinking bottle.
Put a layer of mulch around trees and plants. Mulch will slow evaporation of moisture while discouraging weed growth. Adding 2-4 inches of organic material such as compost or bark mulch will increase the ability of the soil to retain moisture. Press the mulch down around the drip line of each plant to form a slight depression that will prevent or minimize water runoff.
