Using Climate Forecasts to Predict and Reduce Residential Irrigation Demands

Rapid population growth and urbanization in the southeast U.S. are placing increased pressure on water supplies. Residential irrigation is often viewed as the most discreational use of water and has been found to make up over 50% of household water use in some areas.

The objective of this work was to evaluate the use of seasonal forecasts to forecast outdoor water use and how these forecasts can be used by water managers to make decisions. Specifically, this project:

• Analyzed historical residential water use data from two utilities in North Carolina and two in Florida to determine patterns of outdoor water use.

• Investigated strategies for reducing residential irrigation water use.
• Generated an ensemble forecast of a drought index using the seasonal climate outlooks produced by the Climate Prediction Center.
