Résumé
In response to the water shortages of 2002, Colorado utilities adopted numerous policies promoting water conservation. However, despite this demand-management emphasis, utilities are still distinguishing between the impacts of conservation programs and the psychological impacts of the drought itself. That is, water managers are unsure if post-drought decreases in water consumption are solely due to utility-controlled policies or if they result from a combination of drought awareness and/or permanent changes in water-use behaviors. For this reason, gauging the effectiveness of conservation policies requires answering the following : First, did awareness of the drought lead consumers to conserve more water than predicted, given utility policies alone ? Next, if drought awareness did influence demand, is continued awareness—as opposed to utility policies or permanent changes in water use—the reason water demand has failed to return to pre-drought levels ? To answer these questions, this research estimates an econometric water demand model using billing data from a major Colorado utility. Results show that drought awareness did decrease water demand both during and after the height of the drought ; however, baseline demand still appears to be trending downward even after we control for both drought awareness and utility policies.
