12. The vital role of electrical energy for
Arizona water services
Joseph H. Hoover

12.1. INTRODUCTION

The southwest United States is a water-scarce, arid region that is especially
challenged by increases in coupled water­energy demand. The population
of Arizona, which is expected to increase by more than 4 million people
between 2009 and 2030, compounds the challenges associated with the
water­energy nexus. This compels water providers to address increas-
ing energy usage related to water services (Scott et al., 2007). Research
on the water­energy nexus includes determining water needs for energy
production and energy usage for water services. The water demand for
energy generation is well documented (Solley et al., 1998; Electric Power
Research Institute [EPRI], 2002b; Hutson et al., 2004; Pasqualetti and
Kelley, 2008; King and Webber, 2008) and is detailed in other chapters
of this book; however, few studies report quantified energy demands for
water services in the Southwest, particularly for rapid-growth areas that
experience water scarcity such as the state of Arizona.
Basic conceptual and empirical questions remain unanswered regard-
ing the energy implications of increasing water demand and wastewater
services in Arizona. For example, rapid expansion of reclaimed water
is driven by the need to augment existing water supplies. Additionally,
climate-change uncertainty complicates long-term water resources plan-
ning throughout the state. Quantified electricity demands by water-service
type allows for the consideration of scenarios leading to improved under-
standing of the water­energy nexus, at both the local ...
