{"title":"Utility Planning for Data Centers","authors":"Adam T. Carpenter, Rachel Gonsenhauser","doi":"10.1002/awwa.2515","DOIUrl":"https://doi.org/10.1002/awwa.2515","url":null,"abstract":"<p>Data centers are a booming industry right now. With the rapid growth of artificial intelligence (AI) and our ever-expanding hunger for digital services personally and professionally, the growth of these facilities is all but inevitable. Data centers often house thousands of servers and other computing equipment to produce these services, all of which require electricity and cooling, consuming energy and water resources in the process. In some ways, the challenges associated with this growth parallel those of other industrial sectors in the past; in other ways they present new and unique challenges.</p><p>Various federal policies have supported the continued development of AI, including executive orders (e.g., 13960 and 14179), funding to reinforce AI innovation, and <i>America's AI Action Plan</i>. More than 1,200 data centers have been built or approved for construction—and this number is expected to increase considerably. As data centers are not evenly distributed geographically, some areas will see many and others will see few to none, making their effects variable.</p><p>Economic benefits related to data centers are many, and the digital services they provide are important. The facilities can generate significant tax revenue locally without the need for many of the public services a residential or commercial district requires. With that said, they can also have impacts on the water sector if not planned for appropriately.</p><p>The <i>2024 US Data Center Energy Usage Report</i> estimated that direct water consumption attributed to cooling has grown from 5.6 billion gallons (2014) to 17 billion gallons (2023) and is projected to reach 40–73 billion gallons by 2028. Given that power generation itself also consumes water, data centers consume additional water indirectly through their electricity use. The report estimated the indirect water footprint of data centers in 2023 at 211 billion gallons. A high degree of uncertainty remains regarding the effects of data centers on total water and electric demand, given that the extent of the growth and the needs of future data centers is not yet known.</p><p>Water systems may be faced with challenges in achieving sufficient infrastructure capacity to address data centers’ needs. As data centers are frequently built where land can be affordably acquired, they may be located well outside the core of a water utility's transmission system, creating distribution challenges. Utilities should account for any resulting changes to their water source(s) and to treatment, transmission and distribution infrastructure, and wastewater collection and treatment. This will ensure sustainable, uninterrupted, and affordable water supply in the long term. Conversely, utilities should be cautious in their planning to ensure they do not overbuild and end up with stranded assets if high demand does not materialize. As data centers are part of a quickly evolving technology sector, the technology used could change and consid","PeriodicalId":14785,"journal":{"name":"Journal ‐ American Water Works Association","volume":"117 9","pages":""},"PeriodicalIF":0.4,"publicationDate":"2025-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://awwa.onlinelibrary.wiley.com/doi/epdf/10.1002/awwa.2515","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145272950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mercer","doi":"10.1002/awwa.2514","DOIUrl":"https://doi.org/10.1002/awwa.2514","url":null,"abstract":"<p>Ongoing innovation and research are vital to advancing how water professionals safeguard public health, protect the environment, and strengthen communities through better, safer water. Innovation and research are the foundation of continuous improvement across policy and practice; AWWA has long recognized their importance through its publications and awards, including the prestigious A.P. Black Research Award, which honors individuals whose work has significantly advanced water science.</p><p>This month's <i>Journal AWWA</i> features an interview with Karl Linden, the 2025 A.P. Black Research Award winner and a recognized innovator whose work, like that of previous A.P. Black award winners, exemplifies the best of our field—trailblazers whose research has shaped how we understand and manage safe drinking water. Their contributions remind us that the challenges we face today require not only technical expertise but also vision, leadership, and connection to the communities we serve.</p><p>One of the best places to witness the vanguard of innovation in the water industry is at AWWA's Water Quality Technology Conference (WQTC), a showcase each November for researchers to present their latest findings and discuss emerging issues with colleagues from around the world. Scientists, students, engineers, and utility leaders make up the research teams that gather at WQTC to share new insights and spark collaboration to further promote safe drinking water.</p><p><i>AWWA Water Science</i> (<i>AWS</i>), our dedicated research journal, continues its mission of publishing peer-reviewed articles on the physical, chemical, biological, and ecological processes that affect drinking water quality and quantity. You’ll also find monthly Research Highlights in <i>Journal AWWA</i>, offering abstracts and links to full <i>AWS</i> articles—making it easy to stay informed of the very latest developments.</p><p>Promoting research in AWWA's journals and at its conferences inspires creative solutions that meet evolving water challenges. But true innovation is not just a change—it must also be an improvement, and continuous improvement is a core value of the water industry. Whether through incremental advances or disruptive technologies, it takes the concerted efforts of all water professionals to foster and imbed an improvement mindset.</p><p>The water industry has many conventional ways of doing things, so its leaders need to encourage staff to ask questions, remove institutional barriers, and develop incentives to be original thinkers within their organizations. And it is our collective responsibility to create a forward-thinking environment that questions the processes and approaches that are taken for granted as standard practice today.

LaFrance","doi":"10.1002/awwa.2528","DOIUrl":"https://doi.org/10.1002/awwa.2528","url":null,"abstract":"&lt;p&gt;Many of us are driven to “be first” from the day we step onto a playground as children—who can swing the highest, run the fastest, or kick the ball the farthest. The drive continues into the classroom as well—who can do their math correctly, spell all the words, or even be at the front of the line, leading the way to lunch.&lt;/p&gt;&lt;p&gt;When we were young, it was all about being first. Being first meant something: you were the leader, others would follow you, and they would often learn from you. For adults, especially as water professionals, &lt;i&gt;going&lt;/i&gt; first is a completely different concept from &lt;i&gt;being&lt;/i&gt; first. It takes a little more thought. We have to assess whether we want to go first when there is uncertainty—after all, we aren’t on the playground anymore.&lt;/p&gt;&lt;p&gt;As a society, we count on leaders who are willing to go first, just like we did in school. We need someone to solve the problems and lead the way to the future so we can learn from them. In short, we need people who are willing to take the first step and, importantly, we need people who accept the idea that they are the ones who don’t just go first but instead &lt;i&gt;get&lt;/i&gt; to go first.&lt;/p&gt;&lt;p&gt;Lillian is featured throughout AWWA's Water 2050 video titled &lt;i&gt;Metro Vancouver: From Wastewater Treatment to Renewable Fuel Pioneer&lt;/i&gt;, which you can find at www.awwa.org. The video highlights how Metro Vancouver is converting its wastewater sludge into fuel through a process called hydrothermal liquefaction (HTL for short). This first-of-its-kind, innovative process provides a new way for wastewater utilities to transform their solids into a valuable fuel resource. It also supports a one-water philosophy and circular economy concept. As Metro Vancouver staff explored the risks of HTL, they got a confidence boost when they worked with The Water Research Foundation, which conducted a bench study to test the idea. The study results indicated that HTL would work.&lt;/p&gt;&lt;p&gt;In the Water 2050 video, Lillian acknowledges what all water professionals experience at some point: “With innovation, everyone is waiting for someone else to go first… .” She pauses for a moment, and then after a deep breath, a wide smile emerges as she proudly ends the sentence, “and in this case, we &lt;i&gt;get&lt;/i&gt; to go first.”&lt;/p&gt;&lt;p&gt;It wasn’t just what Lillian said but how she said it that struck me. Her enthusiastic emphasis was on the word “get,” and that changed everything. Suddenly she wasn’t just going first, she was &lt;i&gt;getting&lt;/i&gt; to go first. Lillian was fully aware of the privilege her utility had by having the opportunity of being the first to solve this challenge. By getting to go first, Metro Vancouver could create a path for the rest of us and influence the future.&lt;/p&gt;&lt;p&gt;Fortunately, in the history of water there are many Lillians. Take, for example, John Leal. He was an American physician who, in partnership with George Warren Fuller, was responsible in 1908 for the introduction of chlorine into the water of a municipa","PeriodicalId":14785,"journal":{"name":"Journal ‐ American Water Works Association","volume":"117 9","pages":""},"PeriodicalIF":0.4,"publicationDate":"2025-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://awwa.onlinelibrary.wiley.com/doi/epdf/10.1002/awwa.2528","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145272725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
