Water Management & Water Equity in Phoenix, Arizona

By Kathryn Sorenson, Director, City of Phoenix Water Services Department

Kathryn Sorensen is the Director of the City of Phoenix Water Services Department.

In a desert city like Phoenix, water is the foundation of public health, economic opportunity, and quality of life. Phoenix’s water supply is sound and sustainable as a result of multiple water sources and a logical, methodical approach to supply planning, infrastructure management, conservation, and drought preparation. Living in the desert imparts a deep appreciation for the value of water, which has driven the City of Phoenix to methodically manage water supplies for reliability in our desert environment. There are complicated tradeoffs between sustainable management of water supplies, conservation, affordability, infrastructure investment, and equity. At the same time, smart and equitable water management can foster broad opportunity for the entire community. In Phoenix, we’re continuously working on water management, and we’re now bringing water equity into focus as well.

Phoenix has been a leader in the reuse of wastewater for forty years.  We’ve also banked water underground that we don’t need today, for availability when shortages of Colorado River water occur. And we have access to over a trillion gallons of native groundwater, which we fastidiously protect as a savings account for future generations. Our supplies include water from the Salt, Verde, and Colorado Rivers, and reclaimed wastewater.

Conservation is the foundation upon which all of our sustainable water management strategies are based. Our water usage rates have fallen 30% in twenty years, which means that we deliver less water today than we did twenty years ago, while serving nearly 400,000 more people. We have effectively decoupled growth and water use in Phoenix. We did this by focusing on long-term culture change regarding the way people view water in the Valley of the Sun. Odd as it sounds, we don’t want our customers reacting to drought or hydrologic conditions. Instead, we want them to use water wisely everyday as a lifestyle choice here in our desert city. This culture change in the way people view and use water in Phoenix has been brought about through improvements in technology (water efficient appliances), through decades of extensive education and outreach, and through the use of a strong price signal in our water rates.

Phoenix’s water rate structure, first adopted in the early 1990’s, is pretty ingenious. Phoenix charges more for water in the summer than in the winter. This sends a direct price signal to customers to scrap the grass and lush landscaping that requires a ton of water to stay alive in our hot summers, and convert to desert-adapted landscaping, called xeriscape, instead. And this is exactly what has happened.  Back in the 1970’s approximately 80% of single-family homes had majority-turf landscapes. Today, that number hovers at less than 10%.

But Phoenix’s water rates, while effective at encouraging conservation, are also affordable for basic, indoor needs. This is important in a city where the municipal water utility is the monopoly provider, and temperatures soar over 115 degrees in the summer. Phoenix’s monthly fixed charge for water is very low—approximately $4.50 per month—and includes an “allowance” of water ample for basic household needs. So while Phoenix sends a conservation signal through summer pricing, it also manages to ensure that water remains affordable for basic needs. A 2018 study published in the Journal of the American Water Works Association ranked Phoenix’s water as most affordable among the 25 largest cities in the country.

The fact that Phoenix water is affordable for basic household needs helped us push a recommended two-year rate increase over the finish line. In January, 2019 Phoenix City council formally voted to increase water rates by 6% for two straight years. These rate increases were necessary to support a $500 million bond program, which will be used to fund infrastructure necessary to withstand shortage on the Colorado River as well as extensive pipeline rehabilitation and replacement in the oldest parts of town, generally in some of the poorest neighborhoods in our service territory.

  • Sustainably managed water supplies
  • Strong conservation price signal and a culture of wise water use
  • Affordable water for basic needs
  • Responsible investment in infrastructure

We’re done here, right?

Not done. Things get complicated here in Phoenix where the City Services Bill includes not just water and wastewater services but also solid waste services and various city taxes. Water might be affordable at basic levels, but its billing is joined with other city services that, combined, entail a larger bill and increase the risk of water insecurity through disconnects for nonpayment.  Water insecurity tracks poverty and can disproportionately affect the most vulnerable. Adding to this, an array of fees for utility starts and stops, unauthorized use, and late payments can place burdens on vulnerable customers that are difficult to overcome.

Ironically, utility disconnects are necessary to ensure the financial viability of our water utility and the continued investment in the rehabilitation and replacement of aging infrastructure that provides safe, clean, reliable water deliveries in the first place. No water utility wants to disconnect customers, but failure to collect revenue can lead directly to a lack of funds for investment in infrastructure, which also can have disproportionate impacts on poor families who often live in areas most in need of improvements.  We have seen this story play out in cities back east, with tragic consequences for the most vulnerable.

Like other utilities, Phoenix Water uses various programs and procedures to avoid utility disconnects. We fund a robust customer assistance program, give ample notice before disconnects, offer payment plans, suspend disconnects on days of extreme heat, and work closely with the nonprofit community to match customers in need with the resources that can get them on their feet.

But is all of this enough? And here again, things get complicated in a desert city where water use has a direct and tangible impact on quality of life. While Phoenix water is affordable for basic, indoor needs, it is purposefully not affordable for outdoor water use to drive conservation. That conservation signal has worked very well and the use of desert landscapes has exploded. Those landscapes are good for local flora and fauna, but do little for, and maybe even exacerbate, the unrelenting urban heat island that keeps summer temperatures above 100 degrees even at night. Wealthy families, oblivious to the cost, plant lawns that mitigate the urban heat and increase property values. Poorer families swelter. As we face a hotter and drier future, the tradeoffs between conservation and quality of life will come into greater focus, and environmental justice will be the center of that conversation.

According to the U.S. Water Alliance, water equity occurs when all communities have access to safe, clean, affordable drinking water and wastewater services; are resilient in the face of floods, drought, and other climate risks; have a role in decision-making processes related to water management in their communities; and share in the economic, social, and environmental benefits of water systems.

We recently asked our citizens’ committee, as representatives of the broader community, to tackle issues of water equity.  Over the next year, they will examine where we currently stand on:

  • Broad access to safe, clean, affordable water
  • Our resiliency in the face of climate risks
  • The role customers have in decision-making related to water in their communities
  • The degree to which the benefit of our water system is broadly shared in the community

The citizens’ committee will be asked to determine whether there is more we can or should do in these areas to promote water equity. They will examine our current utility billing fees and procedures, whether our customer assistance program is adequately funded, the degree to which our plumbing retrofit program should be expanded, languages offered in our customer service center, investment in aging pipelines in struggling neighborhoods, our efforts to ensure resiliency in the face of shortage on the Colorado River, our grassroots involvement in neighborhoods and community groups, our small business enterprise programs, the trajectory and pace of our facility beautification program, and our efforts to create a water workforce pipeline in the community. This is a lot to take on, and there are a lot of tradeoffs at play, but these issues will only become more complex and more difficult to overcome if they are not confronted now.

Phoenix Water Services inherited an incredible legacy of wise water management—one that dates back to the ancient Native Americans who first built the canals that we rely upon to this day.  Phoenix exists where two major rivers come together—this place was carefully chosen. To stand the test of time, we must honor this legacy and continue to push forward with innovative water management strategies that ensure water remains the foundation of public health, economic opportunity, and quality of life—especially for the most vulnerable among us.

  2. WaterBeads is a federal solution to water in the desert SW. It is an energy self-sufficient solution that is proposed to bring Mississippi River water across the continent to Los Angeles. In the first few steps it only has to collect water in East Texas where is rains more than 60 inches a year and deliver that water to Dotsoro Colorado where it goes into the headwaters of the Colorado River and ends up in southern Arizona and an existing man made canal takes it on to Los Angeles. As more of this spare 511 million acre feet of water is moved West the Colorado River channel may not be big enough so more WaterBeads system would be built next to the river. Federal laws will need to be updated to make this even legal. The water that the Mississippi River dumps into the Gulf of Mexico just causes a giant dead spot for marine life and does no one any good. As good stewards of the water God gave us we should move a small portion of that water to the desert southwest to feed the people who have moved there. Sun powers this and zero pollution is created. This is cheaper than desalination in LA.

  3. This is a really comprehensive blog; it touches on a lot of issues that affect water equity. Is Phoenix considering a fee system for water utilities that is progressive, i.e. adjusted for income especially for people of very low income or at poverty level? An adjusted fee system might help reduce the number of disconnected customers.

  4. “A remarkable feature of this tale is how failure is so commonly portrayed as success. Western boosterism is key to understanding that contradiction. Selective, willful optimism obscures risk, forgives failure, and promises rectification in the future.”

Closing the Water Access Gap in the United States

Closing the Water Access Gap in the United States

Today, over 2 million Americans are living without access to clean, running water. The newly released ‘Close The Water Gap’ report by DigDeep and the US Water Alliance pulls back the veil on America’s hidden water crisis.

This is the first-ever comprehensive look at indoor water access across the United States, and its findings are explosive: Race is the strongest predictor of vulnerability. In six states (plus Puerto Rico), progress is actually backsliding. More than 44 million Americans are served by water systems with recent violations of the Safe Drinking Water Act.

The Link Between Climate Change & Water

The Link Between Climate Change & Water

When thinking about conserving water, we should also be focusing on how more efficient water use correlates with energy savings. Studies show that when households participate in water savings programs, they also conserve energy and reduce strain on the power grid during peak demand periods while saving consumers money on their utility bills.

Water utilities can also dramatically increase their energy efficiency and reduce overall energy usage by adopting locally based solutions. For many municipal governments, drinking water and wastewater treatment plants are typically the largest energy consumers, often accounting for 30 to 40 percent of total energy consumed. Overall, drinking water and wastewater systems account for approximately two percent of energy use in the United States, adding over 45 million tons of greenhouse gases annually.

Using Data to Reduce Public Health Risk

Using Data to Reduce Public Health Risk

Addressing the impact of heat on health is well-aligned with MCDPH’s vision and mission “to make healthy lives possible” by protecting and promoting the health and well-being of MC residents and visitors. The climate has significant impacts on our community’s health. Through extensive surveillance and community surveys, we have demonstrated the importance of local public health data to increase buy-in from new and existing partners and obtain funding to address this significant public health issue. We encourage other health departments to consider the power of data and collaboration as they seek methods for protecting the public’s health from a changing climate.
