To reduce your watering demand, you can design your landscaping with plants that consume less water. See a helpful guide prepared by EWEB and partners,
Water-Efficient Plants For The Willamette Valley.
The best way to determine your sprinkler system output is to use a watering gauge and ruler to conduct the following test:
- Place your older Green Grass Gauge or a DIY Watering Gauge in an area of the lawn where it receives a typical amount of water.
- Move the gauge around the lawn area between each watering cycle to help identify dry spots.
- Do not place it under trees, shrubs or other plantings.
- If you want to water twice a week, use the two-day a week watering recommendation. If you want to water three times a week, use the three-day a week watering recommendation.
- Run the sprinklers until the watering gauge is filled to the weekly watering recommendation. Emptying the gauge between each watering cycle will help you to know if you are watering the recommended amount each time the sprinklers run.
- You may click the link above to see the weekly recommendation and you have the option at that link to sign up for a weekly Thursday email. (We also post this information on Rainbow's Facebook page.)
