Urban Sustainability and the Fundamental Importance of Water
Really smart people are putting their heads together more frequently to discuss and find solutions to the enormously complex issue of urban sustainability and what the city of the future will look like. They have diverse backgrounds and often long and impressive resumes that can be daunting. I have spent virtually my whole career with one organization called the National Association of Clean Water Agencies (NACWA) and am retiring after several decades leading it – so the primary lens through which I see urban sustainability is water management. I have thought that perhaps my background biases me to the fundamental importance of water among the various infrastructure sectors but I have come to believe it not a bias but a reality.
People are made mostly of water, without it we simply cannot live. Without efficient water management and sanitation there is illness and disease – we see this more in under-developed countries but we must never let down our guard here at home either. And with climate change there is either too much water or too little water – both of which are causing catastrophes of a different nature and sometimes of different severity in urban and rural areas from coast to coast. With population growth, there are more mouths to feed and with more mouths to feed there is more pollution from agriculture, industry and households challenging our ability to control water pollution. Yet, a reliable, clean water supply is also critical to all manufacturing/industrial processes and to virtually every business and service imaginable – without sound water management there is no cloud computing, no restaurants, no electricity, oil or gas, etc. You get the point!
In short urban growth and sustainability depends more on water than arguably any other resource or commodity. And yet, all too often, water investment and long-term planning at the local, state and federal level can be an afterthought. NACWA has led an effort called the Water Resources Utility of the Future (UOTF) initiative. Its objective is to spotlight the unparalleled and innovative work clean water utilities are doing at the local level to not only contain growing pollution challenges, but to also create local jobs, spur economic growth, improve the environment and drive sustainable innovation. Utilities are creating energy from the wastewater treatment process to help drive us toward energy independence. They are pulling phosphorus from the waste stream, creating an endlessly reusable fertilizer as phosphorus nears dangerous shortages internationally. They are planting trees, building wetlands, green roofs, bioswales and other natural processes to keep water in place, rebuild groundwater supplies, create green space that adds to the quality of life while also improving the environment and water quality. They are using advanced technology to reuse and recycle wastewater as a key method to battle the drought and ensure sufficient water supply for agricultural use, manufacturing, and energy production.
I hope you will listen to the public clean water agencies’ stories or even visit your local utility. You will find them to be eye-opening in terms of the technologies they employ and the near-heroic efforts the public stewards who run them are making on behalf of urban renewal and sustainability. We must tout their efforts and underscore the imperative need to value water more highly as we piece together the complex puzzle of urban sustainability. We have come to rely on these water systems without taking full responsibility for the huge investment it will take to upgrade, maintain and expand them. When developing a plan for urban sustainability a starting place should be the following question: What could be accomplished without daily, reliable clean and safe water? The answer, of course, is nothing.

Spotlighting innovations in urban sustainability and connected technology
Lighting infrastructure is a perfect example of futureproofing. As cities are swapping out traditional high-pressure sodium street lights with energy-efficient LEDs and smart nodes that can remotely monitor and control the lights, don’t just be thinking about a smart lighting solution. Think about the position those streetlights are in to support so much more, like intersection safety analytics, parking optimization, and gunshot detection.
The idea of multi-channel civic engagement and the role of the grassroots community marketer is being implemented by forward-thinking smart city leaders who understand the importance—and economic benefits—of giving their constituents a voice. More investments are being made into digital systems that reach and engage the public.
From an energy type standpoint, a city’s electric utility can make a big difference regarding which actions cities should undertake. For instance, a city in the service territory of an electric utility with ambitious plans to decarbonize its generation mix may want to focus greater attention on future emissions scenarios versus current emissions when making decisions on priorities. This would mean focusing actions on transportation, space heating, and industrial processes, since those would likely be greater contributors to emissions (vs. electricity) in such a future scenario.
