Weekly Watering Number

Weekly Watering Number

Everyone wants a beautiful Lawn and Garden – however, we also need to think about conserving water. The good news is that landscapes can be maintained with far less water than you think. Want to know exactly how much you should be watering each week? By using the weekly watering number you can do just that. This number is available each year April – mid-October.

The Regional Water Providers Consortium have contracted with a weather forecasting service to provide a free weather forecast and zip code specific Weekly Watering Number each Thursday (April – September). This number is based on historical data (evapotranspiration, rainfall, and other data points) from the previous week, but it is used to determine how much to water lawns and gardens during the current week. As the weather changes throughout the watering season, so does the Weekly Watering Number, this allows you to give your lawn and other plants exactly what they need and not wastewater.

To use the Weekly Watering Number, you will need to take a few minutes to determine how long it takes your automatic sprinkler system or non-automated system to water 1 inch of water. Once you know how long that takes you can use the Weekly Watering Number to adjust your watering duration/frequency throughout the watering season.

Go here to sign up for the Weekly Watering Number and start receiving your zip code specific watering number every Thursday of every week and start watering smart today!

Follow these general guidelines to use the Weekly Watering Number for watering other types of plants in your yard:

• Shrubs: 50% of the Weekly Watering Number
