{"title":"Water's Pressure","authors":"Kenneth L. Mercer","doi":"10.1002/awwa.70154","DOIUrl":"https://doi.org/10.1002/awwa.70154","url":null,"abstract":"<p>Pressure is everything in a water system. Too little pressure and water cannot reach customers. Too much pressure accelerates the deterioration of pipes, valves, and other critical infrastructure. Maintaining the right amount is essential for consistent water delivery—and the same can be said for the water industry itself.</p><p>Every day, water and wastewater professionals operate under tremendous pressure to protect public health, safeguard the environment, and provide reliable, affordable services. Like hydraulic pressure in a distribution system, these external forces must be carefully managed. Too little urgency can lead to complacency, but too much can strain organizations, budgets, and people. The challenge is in finding the right balance.</p><p>For example, customer expectations continue to put strain on utility leaders and staff. Customers want timely information during outages, rapid updates on water quality concerns, and greater transparency about utility operations. At the same time, utilities face rising costs for treatment, infrastructure renewal, and daily operations while struggling to address ongoing workforce shortages.</p><p>Regulatory pressures are increasing as well. New and evolving requirements related to per- and polyfluoroalkyl substances, lead, disinfection byproducts, and other emerging contaminants are reshaping views on public health protection. New and revised regulations are intended to strengthen operations, but they also require substantial investments in monitoring, treatment technologies, reporting, and compliance. Utilities are expected to keep pace with rapidly evolving science while fully serving their communities.</p><p>Cybersecurity has emerged as another major stressor. Recent attacks on water infrastructure have demonstrated the vulnerabilities of operational technology and digital systems. As utilities embrace automation, remote monitoring, and data-driven operations, protecting critical systems from attack has become just as important as maintaining them.</p><p>And then there is nature. Droughts, floods, wildfires, and extreme weather events are challenging utilities in ways that would have seemed extraordinary only a generation ago. Too much water or not enough are no longer isolated concerns, and for many communities, they are now part of routine planning and operations.</p><p>Pressure is more than a hydraulic parameter. It is a defining characteristic of modern utility management. Just as water systems depend on maintaining the right pressure to function properly, utilities depend on skilled professionals who can manage the growing challenges around them. Whether for pipes or people, successful pressure management remains fundamental to delivering safe, reliable water in an increasingly pressure-filled world.

{"title":"A Mighty River Under Stress","authors":"David B. LaFrance","doi":"10.1002/awwa.70167","DOIUrl":"https://doi.org/10.1002/awwa.70167","url":null,"abstract":"&lt;p&gt;It was a beautiful day, and my wife, Justine, and I were the only kayakers on the water. Hauling a kayak half a mile across a dried reservoir bed, which had turned into ankle-deep mud for the last 100 yards, apparently was more than other kayakers could tolerate. We were kayaking on Granby Reservoir, about 25 miles as the crow flies from the Colorado River headwaters in Rocky Mountain National Park. The reservoir is a key part of the Colorado River system, and its unusually low water level told a troubling story of a river that that was supposed to travel another 1,400 miles.&lt;/p&gt;&lt;p&gt;This is not the first time the Colorado River has been under stress. Some blame the “millennium drought” that began in 2000, while others argue the seeds were planted in 1922, when the Colorado River Compact divided more water among parties than the river could sustainably provide. Either way, the river's importance to the West cannot be overstated. Approximately 40 million people and seven states across the Southwest rely on it. Colorado, New Mexico, Utah, and Wyoming are referred to as the Upper Basin states; Arizona, Nevada, and California are the Lower Basin states. The Colorado river not only provides municipal water but also helps irrigate millions of acres of western farmland. It is not just a hard-working river but also an environmental treasure beloved by kayakers, fly-fishers, recreationists, artists, and nature lovers from around the world. It even chiseled one of the world's most spectacular natural wonders—the Grand Canyon. No question about it—it is a mighty river under extraordinary stress.&lt;/p&gt;&lt;p&gt;As water and policy professionals discuss the Colorado River's current low-flow challenges, the word &lt;i&gt;aridification&lt;/i&gt; is increasingly in vogue. Like many people, I wasn’t quite sure what that term meant and mistakenly assumed it was simply a new way of describing climate change or drought.&lt;/p&gt;&lt;p&gt;In reality, aridification is not a new concept at all. According to &lt;i&gt;Merriam-Webster&lt;/i&gt;, the word dates back to 1855. More importantly, it is not the same as climate change or drought. In many ways, it is even more concerning than a drought and directly tied to the future of water supplies.&lt;/p&gt;&lt;p&gt;Aridification describes a gradual, long-term shift from a wetter climate to a permanently drier one. Unlike a drought, which is generally viewed as temporary, aridification does not suggest that water conditions will eventually return to normal. And while climate change affects many parts of the environment, aridification focuses specifically on water and its future. For those concerned with rivers, reservoirs, and water supplies, &lt;i&gt;aridification&lt;/i&gt; appears to be the precise term for the state of the Colorado River.&lt;/p&gt;&lt;p&gt;As I write this column, the “solution owners” for the Colorado River challenges appear to be changing from the water leaders of the Upper Basin and the Lower Basin to the federal government.
