In this study, the ARIMAX time-series model is used to identify the significant factors that
impact water consumption and evaluate water conservation effectiveness in Dallas, Texas.
The results show that rainfall, the high temperature days and economic conditions have
statistically significant effects on the consumption in addition to the conservation efforts.
Water consumption increases as the local economy flourishes, rainfall decreases or the
number of high temperature days increase. Population and changes to rates do not impact
consumption in this study. To evaluate the citywide water conservation effectiveness, the
water savings is estimated by comparing the actual consumption with the estimates made by
the model which assumes minimal conservation implementation. After the removal of the
rainfall, high temperature and economic effects, the total water savings due to the
conservation efforts in the City of Dallas is 70.5 billion gallons from FY2002 to FY2007. Includes 9 references, tables, figures.
