As urban populations grow, water managers are becoming increasingly concerned about water scarcity. Water managers once relied on developing new sources of water supply to manage scarcity but economically feasible sources of unclaimed water are now rare, leading to an increased interest in demand side management. Water managers in Las Vegas, Nevada have developed innovative demand side management strategies due to the cities rapid urbanization and limited water supply. Three questions are addressed. First, in the developed areas of the Las Vegas Valley Water District service areas, how did vegetation area change? To quantify changes in vegetation area, the Matched Filter Vegetation Index (MFVI) is developed from Mixture Tuned Match Filtering estimates of vegetation area calibrated against vegetation area estimates from high-resolution aerial photography. In the established city core, there was a small but significant decline in vegetation area. Second, how much of the observed decline in per capita consumption can be explained by Las Vegas land cover and physical infrastructure change that resulted from extensive new construction and new use of water conserving technology, and how much can be attributed to water conservation policy choices? A regression analysis is performed, followed by an analysis of three counter-factual scenarios to decompose reductions in household water into its constituent parts. The largest citywide drivers of change in water consumption were increased water efficiency associated with new construction and rapid population growth. In the established urban core, the most significant driver was declining vegetation area. Third, water savings generated by a conservation program that provides incentives for homeowners to convert grass into desert landscaping are estimated. In the city core, 82 gallons of water are saved in June for each square meter of landscape converted in the first year after conversion, but the savings attenuate to 33 gallons per meter converted as the landscape ages. Voluntary landscape conversion programs can generate substantial water savings. The most significant result is that the most effective way to ensure long term, sustainable reductions in water consumption in a growing city without changing water prices is to support the construction of water efficient infrastructure.

For the last 10 years, the American Southwest has been experiencing the most persistent drought conditions on record. Based on future climactic predictions, there is a dire need to reduce water usage within Phoenix. An environmentally responsible behavior such as low water use landscaping (xeriscaping), has been shown to reduce household water consumption by 40%-70%. While much is known regarding the relationship between socio-demographics and xeriscaping choices, the influence of other variables remains to be explored. Using data from the 2017 Phoenix Area Social Survey, this study investigates the influence of two additional variables - ecological worldview and place identity on xeriscaping choice. Data was analyzed using two models - Ordinary Least Squares (OLS) and Linear Probability Model (LPM). Ecological worldview and place identity, along with income, ethnicity, and gender, were all found to be positively related to xeriscape preference. Additionally, when compared to the LPM, the traditional OLS was found to still be the most robust and appropriate model when measuring landscape preference. Finally, results suggested that programs to foster identity with the local desert mountain parks may help to increase xeriscaping in the Valley and thus lower residential water use.

Drought is one of the most pressing issues affecting the future of the standard of living here in Phoenix. With the threat of water rationing and steep price hikes looming on the horizon for water customers in California, the desert southwest, and in drought-stricken communities worldwide, industrial designers are in a prime position to help improve the experience of water conservation so that consumers are willing to start taking conscious steps toward rethinking their relationship with water usage.
In a research group, several designers sought to understand the depth and complexity of this highly politicized issue by interviewing a wide variety of stakeholders, including sustainability experts, landscapers, water company executives, small business owners, reservoir forest rangers, and many more. Data synthesis led to the conclusion that residential water use is a lifestyle issue, and the only real way to conserve involves a significant shift in the collective idea of an “ideal” home—lawns, pools, and overwatered landscaping contribute to 70% of all water use by residences in the Phoenix area. The only real way to conserve involves increasing population density and creating communal green spaces.
DR. DISH is a dishwashing device that is meant to fit into the high-density living spaces that are rapidly being built in the face of the massive exodus of people into the world’s cities. To help busy apartment and condominium dwellers conserve water and time, DR. DISH converts a standard kitchen sink into a small dishwasher, which uses significantly less water than hand-washing dishes or rinsing dishes before putting them into a conventional dishwasher. Using advanced filtration technology and a powerful rinse cycle, a load dishes can be cleaned with about 2 gallons of water. Fully automating the dishwashing process also saves the user time and minimizes unpleasant contact with food residue and grease.
This device is meant to have a significant impact upon the water use of households that do not have a dishwasher, or simply do not use their dishwasher. With a low target price point and myriad convenient features, DR. DISH is a high-tech solution that promises water savings at a time when every effort toward conservation is absolutely critical. As we move toward a new era in determining water rights and imposing mandatory restrictions upon each and every person living in affected areas, creating conservation solutions that will be relevant for the lifestyles of the future is especially important, and the agility of designers in coming up with products that quickly cut consumer water consumption will be a key factor in determining whether humanity will be able to adapt to a new era in our relationship with natural resources.

As we already know, fresh water is essential to human life as it sustains and replenishes our bodies. Water sustainability is clearly an important issue that need to be addressed in our world of growing demand and shrinking resources. The ASU Future H2O program seeks to make a difference in the development of water sustainability programs by performing experiments that convert urine into reusable water. The goal is to make reusable water processes become inexpensive and easily accessible to local businesses. This promises a significant environmental impact. In order to make the process of development more efficient we can combine engineering technology with scientific experimentation. As an engineering student and an advocate of water sustainability, I have a chance to design the front-end platform that will use IoT to make the experimental process more accessible and effective. In this paper, I will document the entire process involved in the designing process and what I have learned.

Los Angeles, California and Phoenix, Arizona are two naturally water-scarce regions that rely on imported water to meet their local water needs. Both areas have been experiencing an ongoing drought that has negatively affected their local water supply. Populations in both cities continue to grow, increasing overall demand for water as the supply decreases. Water conservation is important for the sustainability of each town. However, the methods utilized to conserve residential water in the two areas differ drastically; Los Angeles has implemented involuntary water rationing and Phoenix has not.

The widespread effectiveness of involuntary restrictions makes them a popular management scheme. Despite their immediate effectiveness, little is known about how involuntary restrictions affect attitudinal precursors towards the behavior in question and thus, whether or not the restrictions are potentially helpful or harmful to lasting behavior change. This study adapted the Theory of Planned Behavior to survey 361 homeowners in Los Angeles and Phoenix to examine how involuntary water restrictions shape attitudinal precursors to outdoor water conservation.

This study found that when involuntary water restrictions are present, residents feel less in control of their outdoor water use. However, in the presence of involuntary water restrictions, stronger social norms and stronger support for policy prescriptions over outdoor water use were found. The favorable societal support towards water conservation, conceptualized as social norms and policy attitudes, in the presence of involuntary water restrictions is potentially promising for lasting behavior change.

This project was inspired by Dr. Kelli L. Larson’s research which disproved three common landscaping misconceptions in the Phoenix Valley. The first misconception states that newcomers, not long-time Phoenicians more often have and prefer grassy lawns instead of xeric, desert-adapted landscapes when actually the opposite is true. Secondly, the rise in xeric landscapes is not due to personal choice but rather a variety of other factors such as developer decisions. Finally, Dr. Larson’s research also disproves the assumption that people who possess pro-environmental attitudes correspondingly demonstrate sustainable landscaping behavior, and finds that people with those attitudes actually tend to irrigate more frequently in the winter months. Debunking these misconceptions is important because the long-term impacts of global climate change could have effects on water use in the desert southwest, and promoting water conservation in urban residential landscaping is an important step in the creation of sustainable water use policy. <br/><br/>The goal of my project was to make this information more accessible to broader public audiences who may not have access to it outside of research circles. I decided to create a zine, a small batch, hand-made mini-magazine, centered around disproving these myths so that the information could be distributed to broader audiences. I conducted informal stakeholder interviews to inform my design in order to appeal to those audiences, and constructed a 16-page booklet which debunked the myths and encouraged critical thinking about individual water use and urban landscaping habits. The zine included hand-painted illustrations and was constructed as a physical copy with the intention of eventually copying and distributing both a physical and digital version. The purpose of this project is to create a way of accessing reliable information about urban landscaping for residents of the Phoenix Valley, where the climate and geography necessitate water conservation.
