    A Review of Public Drinking Fountain Finders

    By Ayana Crawford and Rapichan Phurisamban

    Public drinking fountains used to be everywhere, providing a reliable source of free, high-quality drinking water outside the home. They are a great alternative to bottled water, with its steep environmental costs and high price (200 to 1,000 times more expensive than tap water or more). Drinking fountains, however, have been disappearing from public spaces over the past few decades. Poor public perception and concerns over water quality (as illustrated in the “water fountain episode” of Parks and Recreation) have played a role in their disappearance.

    Water quality issues at public fountains, when they exist, can be traced to poor cleaning and maintenance or old piping and fixture parts. To ensure the quality and continuance of public drinking fountains, (1) they must be routinely cleaned and maintained; (2) old drinking fountains with lead parts must be replaced or new fountains installed in high-traffic areas, and; (3) modern tools must be developed to let people know how to find these fountains.

    The first two steps are decisions and actions that must be taken by our public agencies, politicians, businesses, and communities. But the third is something that new technology and social media tools can – and are beginning – to offer. We have compiled a list of smartphone applications that will help find drinking fountains and improve access to this valuable public resource.

    We examined 27 Android and iOS drinking fountain mapping apps. Of these, about 37% are available on iOS, 44% on Android, and 19% on both platforms.[1] No perfect app exists; the majority are either largely lacking in fountain locations or are too specific to a certain region to be useful to most users, but we also understand that the options are changing rapidly, and new or updated apps regularly appear. Below, we identify the current apps that are relatively useful and comprehensive and also provide a list of helpful features that we would like to see developers incorporate into future drinking fountain apps or improvements.

    See appendix for a comprehensive list of drinking fountain mapping apps. The list of reviewed apps does not include those that no longer work. Some developers have created the same type of apps for each major city (for example, the Paris Amenities Map); for these we only include one example in our list.

    Drinking Water Fountain App

    Picture3 Picture2 Picture1

    Drinking Water Fountain is our featured app for Android. NiSoft, the app developer, draws on crowd-sourced data from OpenStreetMap (OSM) to map water fountains all over the world. Cities with a high number of drinking fountain locations on the app include New York, Zurich, Paris, Madrid, and Rome. Drinking Water Fountain has within-app route navigation (it does not redirect to another app), an offline mode, and a user-input feature that allows users to add new water fountain locations to the map if they have a free account with OSM. The app is straightforward and easy to navigate. It has colored pins to indicate the status of fountains: “green” means functional, “blue” is unknown, and “red” is broken. A very limited number of locations come with descriptions of the fountain’s location and features, such as whether the fountain has a bottle refilling option. Users have the option of changing the distance units between miles and kilometers. The app was last updated in April 2015.


    WeTap App

    Picture6 Picture5 Picture4


    Our featured app for iOS,“WeTap Drinking Fountain Finder, has a long history. Early versions were developed by Evelyn Wendel, UCLA, the Pacific Institute, Google app developers, and Max di Cosimo, an Italian app designer.  WeTap is now its own nonprofit organization, with a goal to “improve awareness, access, and use of public drinking fountains,” thereby improving public health and decreasing the consumption of single-use plastic bottles. Easy to use, the WeTap app maps public drinking fountains on a global scale, providing specific information for each individual fountain. By clicking on the location pins, users can see specific characteristics of each fountain, such as the quality of water flow, whether the fountain is working, and if it is refill- and/or dog-friendly. Users can add and rate water fountains, and there is also an option to add a photograph. However, it is unclear how WeTap verifies the accuracy of user-input information.

    The app has many fountain locations relative to other global drinking fountain apps for both iOS and Android. However, some reviewers cite issues of inaccurate and/or missing locations, suggesting the need to create incentives to promote user engagement as well as a better input verification system. Version 1.0.0 (current) was released in November 2014 and has not be updated since then.

    Quench App

    Picture21 Picture20 Picture19png

    “Quench,” a regional app, is available for both Android and iOS. TVOntario, a government-owned educational television network from Canada, developed this app along with the Bell Fund, the Canada Media Fund, and the Water Brothers TV show. They collaborated with local companies in the Greater Toronto Area to map restaurants and businesses that offer access to free drinking water as well as public drinking fountains. User-submitted locations are screened by the app administrator before being uploaded to the map. Users can also report a location if it is listed on the site but does not provide free water, which is handy when a fountain is not working or when a business turns a Quench user away. The app includes ratings for fountain cleanliness and temperature and a description of each fountain’s location. It integrates Google Maps into its route navigation system. The majority of the app ratings are positive, but reviewers have commented that the app does not work for Samsung Galaxy S5 phones. The app (Version 2.1.0) was last updated in 2013.

    These featured apps are some of the best tools currently available to find the nearest safe and functional public drinking fountains. However, each has limitations; a high number of fountains and accuracy of information is more often provided in apps with limited geographic scope. Apps that have global coverage, on the other hand, generally suffer from a lack of comprehensive and up-to-date data on fountain location and quality. There is a lot of room to make drinking fountain finders more user-friendly and useful. We provide a list of water fountain app “ideal features” below that could help stimulate the use of public drinking fountains.


    Ideal Components of a Drinking Fountain Finder App

    Accurate and informative results

    • A comprehensive list of locations. The most common complaint reviewers have is the insufficient number of mapped fountains.
    • A description of the fountain location, the state of the fountain, the quality of the water, and the water pressure. Photos are also helpful.
    • Ease of adding new fountains to the map or modifying existing data. Users should also be able to submit additional information about the fountain, such as whether the fountain is indoor or outdoor, and whether it has an additional bottle filler and/or pet fountain.
    • A verification mechanism for user-generated data. For example, new locations could be approved by the developer before being added, or the app could only publish locations that have been reported x number of times.
    • A way to encourage users to add new fountains to the app’s database.
    • Timestamps on these submissions to show how recent the information is.
    • The app could map other public amenities (such as restrooms, information kiosks, and bus stations) to improve functionality.

    High functionality

    • An option for users to rate fountains and filter their results based on fountain ratings.
    • Different location pins with different colors and symbols to differentiate between public drinking fountains and businesses that offer free drinking water (if the app has partnered with local businesses), broken and working fountains, and whether the locations are reported by users or not (if applicable).
    • Downloadable maps for offline use.
    • Route navigation to nearby fountains. The option to choose different modes of transportation, such as walking, biking, driving, or taking public transit, is an extra perk.
    • Distance from the user’s current location to the nearest water fountain, provided in both imperial and metric system units. This feature should be available for apps with a global scope.

    Mechanism for alerting relevant agencies to needed repairs

    • Contact information for the agency in charge of maintaining the fountain listed in the fountain description, or the capability to alert a participating agency directly about needed repairs.

    Publicity and outreach

    • A way to encourage the public use of drinking fountains. This could include social media buttons to share fountain locations or an integration with a water intake reminder app containing suggestions for the nearest fountains.



    Below is a comprehensive list of 27 water fountain finder apps available on iOS or Android platform or both, not including those that do not work. The reviews are current as of April 2017.


    ATX Trail [Austin, Texas, USA]
    This is a well-designed, easy to use map of water fountains, restrooms, and historic sites along the Austin Trail in Austin, Texas. The app is simple and fast. Without extra features, everything loads quickly and the locations of the fountains and restrooms are easy to distinguish. It is also able to provide notifications when the user is near a water fountain or restroom. However, it does not offer any information about individual restrooms or fountains, which would be useful and necessary for a comprehensive drinking fountain map.

    Drinking Water [Rome, Italy]
    Limited to Rome’s historical center, Drinking Water appears to have a comprehensive list of fountains, but it is likely out of date (the app was last updated in 2010). By clicking on a pin on the map, users can access a photo of each fountain, report a broken fountain, or add a note. Fountains that are not working are crossed out on the map.

    Findafountain [Global]
    Findafountain started out as a mapping app for London, United Kingdom, but it has expanded to other areas in the UK as well as abroad. The fountain list is most comprehensive for London. The app relies on registered users (“volunteers”) to provide and correct drinking fountain information. The app website indicates that any changes to the map will go through a “rigorous verification process before going public,” but it is unclear what this process entails. Overall, there is adequate information for the fountains that are mapped. The app differentiates between indoor and outdoor fountains, and the state of repair and quality of water are shown by clicking on the location pins.

    Fountain Finder [Chicago, USA]
    Fountain Finder is specific to the Lakefront Trail in Chicago. The app costs $0.99 to download. It shows the location of public fountains, restrooms, and places to eat. It designates which fountains are available year-round, identifies pet-friendly fountains, provides photos of each fountain, and allows users to save the location of their favorite fountains.

    I Nasoni di Roma – Water Finder in Rome [Rome, Italy and a limited number of international locations]
    This is an outdated map of public fountains in Rome (along with a few other international locations). One interesting feature is that the app has a link to a book with a paper map of Rome’s public fountains.

    NYC Bike Buddy [New York City, USA]
    Designed as a bike map, this app includes public features that might be of interest to bikers, including water fountains. The app costs $0.99 and only covers New York City.

    Pulpulak [Yerevan, Armenia]
    This app is made specifically for Yerevan, Armenia; “Pulpulak” is an Armenian word for a public drinking fountain. This app allows users to search for fountains by street name, upload locations, and rate fountains and fountain water by several different criteria, including cleanliness, coolness, and taste. Users can filter their results based on these ratings.

    Tap Map [Vancouver, Canada]
    Although Tap Map is limited to Vancouver, it appears to have an extensive map of public fountains in the city. Clicking on a fountain will reveal a description of its location, who can access it, and who, if anyone, maintains it. Users can also submit new fountain locations.

    WeTap Drinking Fountain Finder [Global]
    Well-designed, fast, and easy to use, WeTap maps public water fountains globally and also provides information about each individual fountain. By clicking on the pins, users can see the quality of water flow, whether or not a fountain is working, and whether a fountain has an additional bottle filler and/or pet fountain. WeTap features many fountain locations when compared to other global iOS drinking fountain finders, but some reviews cite inaccurate or missing locations, suggesting there is still information that needs to be added or reviewed (the total number of written reviews is limited).

    WC Venice [Venice, Italy]
    WC Venice maps restrooms and drinking fountains in Venice, Italy. Location and fees, as well as the hours of operation for weekdays, weekends, and holidays, are provided for each toilet and fountain, when applicable. There is a route navigation feature, and users can input new locations and update information about existing ones.


    Bringing Tap Back [Tennessee, USA]
    This app was created by the Tennessee Clean Water Network to help reduce the consumption of sugary drinks. It maps drinking fountains, bottle refill stations, and public pet fountains and includes route navigation. Each fountain has a description and, in certain cases, a photo. A user can add a location by inputting the current location or adding a pin remotely. The geographic scope is limited to Tennessee, USA, and a few other locations in Seattle, Los Angeles, Atlanta, and Salt Lake City.

    Drink in Italy [Italy]
    A redeveloped version of I Nasoni di Roma, this app is one of the more popular drinking water apps. It is no-frills and straightforward to use. It maps the location of drinking fountains in Italy and provides distances and route guidance, but it does not provide information about each fountain.

    Drinking Water Fountain [Global]
    This app features within-app route guidance to the nearest fountain, an offline mode, and the ability for users to add new fountains through an OpenStreetMap account. The app has a relatively large number of locations, especially for more populated areas. It color-codes location pins to indicate functional or broken fountains as well as fountains that do not have an exact location.

    Drop In App [New York, USA]
    This app, developed by Because Water, has some interesting and innovative ideas for drinking fountain mapping. With the goal of decreasing the number of plastic bottles bought when people are outdoors, Drop In App partnered with businesses to allow the public to access tap water for free. The end result is a nicely designed, easy-to-use map of participating businesses and public water fountains. Pins are color-coded to differentiate between public fountains and participating businesses and to show user-reported locations. Currently, there appears to only be an adequate number of fountain locations listed for particular New York neighborhoods.

    Go CoMo Trails [Columbia, Missouri, USA]
    This app was developed as an electronic trail map for the city of Columbia, Missouri. The developers used GIS to create the system, mapping amenities including water fountains, bike repair stations, and restrooms.

    H2wOrld [Global]
    This app aims to help users find and report free public water sources. Markers on the map indicate the type of water source (e.g., drinking fountains are marked as green) as well as the distance of each fountain from the user’s location (e.g., fountains that are closer to the user’s location are shown in yellow). One significant drawback of this app is that it requires a Gmail account sign-in before users can access it.

    Paris Amenities Map [Paris, France]
    A pixelated map of Paris with the location of nearly every service available, from bicycle rentals to pubs. The app shows more than 15 different amenities, but users can only see public restrooms, ATMs, banks, and post offices with the free version – everything else, including water fountains, comes with the $0.99 version. The app developer has also created an Amenities Map app for 33 other major cities besides Paris.

    TakeABreak: Find Toilets/Taps [Global]
    Created by a software engineering student at the University of Waterloo, this app shows public fountains, restrooms, and restaurants. The app draws information from OpenStreeMap. It does not have an offline mode or colored pins to quickly identify functional fountains.

    Tap Water Ljubljana [Ljubljana, Slovenia]
    Quick and easy to use, the limited scope of this app (17 fountain locations) would only make it useful for those in the main area of Ljubljana, Slovenia. By clicking on a fountain, the user can also see nearby attractions.

    TrailLink – Trails & Maps [USA]
    TrailLink provides a number of trail maps and includes the location of water fountains and other amenities along each trail. In-app purchases are required to access all the maps. This app has an offline feature, which is a useful feature for many hikers.

    Vancouver to Go [Vancouver, Canada]
    This app includes the locations of drinking fountains and over 20 other services and amenities in Vancouver. It also provides information on current weather and road closures. In-app purchases may be required to access some of these features.

    Vienna Mobile – City Map [Vienna, Austria]
    Vienna Mobile is an ad-supported mobile application that maps over 30 attractions and amenities, including drinking fountains, in Vienna, Austria. It provides route guidance via walking, driving, or public transportation. The app shows real-time departures for public transit and provides information on events in the city.
    iOS & Android

    Benches [Global] – Android & iOS
    This app maps locations of drinking fountains, benches, restrooms, and picnic tables. It is one of the few apps containing a relatively comprehensive list of fountains, since the app relies on OpenStreetMap. However, Benches can be challenging to use: it lacks route navigation and has limited zoom-out capability.

    Choose Tap [Southern Australia] – Android & iOS
    This app is relatively fast and appealingly designed. It includes the locations of publicly available restrooms, BBQ pits, and restaurants, as well as drinking fountains. While there is a decent number of fountain locations listed, the list is by no means comprehensive. The app uses the same symbol for all features (for example, a BBQ pit is marked using the same symbol as for a water fountain), so it is not possible to distinguish between the pins on the map unless the user filters out everything except for one feature or manually clicks on each pin. The geographic scope is limited to Southern Australia.

    Fonts BCN [Barcelona, Spain] – Android & iOS
    This mapping app provides information on both public drinking fountains and decorative fountains. It has a simple, yet user-friendly design, and provides route guidance, the distance from the user’s location to each fountain, and basic information about each fountain. Fountain locations are available in either “list view” – which the user can organize by address, name, or distance – or “map view.” The app distinguishes between regular fountains and those that are historically or artistically significant and provides additional historical information about the latter. One important negative aspect of this app is that it requires a number of permissions before installation, including calendar, phone status and identity, and network connections.

    Quench [Ontario, Canada] – Android & iOS
    TVOntario, a government-owned educational television network from Canada, developed this app along with the Bell Fund, the Canada Media Fund, and the Water Brothers TV show. They partnered with local businesses in the Greater Toronto Area to map businesses and drinking fountains at which people can access free water. Users can submit locations, which TVO then screens before uploading them to the map. Users also have the option to report a location if it is listed on the site but does not actually provide free water. The fountains can be rated based on cleanliness and temperature. Although the majority of the ratings for this app are positive, some comments indicate that the app does not work for Samsung Galaxy S5 phones.

    TapIt Metro DC [Metropolitan DC, USA] – Android & iOS
    This app partnered with local businesses in the metropolitan DC area in order to increase public water access. It provides a map which includes pins for both the locations of public fountains and participating businesses providing access to drinking water, but it does not visually differentiate between the two, so users must click on each pin to find out what type of location it represents. Users can “favorite” locations or share locations on social media, such as on Facebook and Twitter.

    [1] See appendix for a comprehensive list of drinking fountain mapping apps. The list of reviewed apps does not include those that no longer work. Some developers have created the same type of apps for each major city (for example, the Paris Amenities Map); for these we only include one example in our list.

    Corporate Water Targets: A New Approach

    By Tien Shiao

    Screen Shot 2017-05-20 at 8.32.06 PM


    Water risks once again rank as one of the top 10 global risks in the 2016 World Economic Forum’s annual report.

    Screen Shot 2017-05-20 at 8.22.58 PMBecause of this, more and more companies view water as a business risk and water stewardship as a solution. As such, they are looking to find ways to measure their performance and progress. However, current methods for creating water stewardship metrics that evaluate on-the-ground projects are inadequate.

    Corporate water targets are often developed with various objectives in mind. Sometimes they are used to demonstrate the company’s leadership to external audience. Sometimes they are used to inform and inspire employees internally. Sometimes they are used to align water efforts across the company’s operations in various regions. And sometimes they are used to mark the company’s contributions to addressing global challenges.

    report cover

    Finding ways to align corporate water targets to public policy and international global policy, such as the Sustainable Development Goals, ensures corporate water targets address global water challenges. At the same time, each river basin is unique and requires a unique type and degree of action. This complexity of understanding and responding to local needs, while also contributing to global development goals brings a great deal of complexity to corporate water target setting.

    That’s why CDP, UN Global Compact CEO Water Mandate, Nature Conservancy, World Resources Institute and WWF published a new discussion paper calling for a new approach to set context-based corporate water targets. We believe through creating guidance on the topic, we can assist companies in navigating this complex, yet vital, water stewardship challenge.

    What are Context-Based Water Targets?

    Context-Based Water Targets were inspired by Science Based Targets for climate change, where companies set corporate targets consistent with the right level of carbonization based on science.  This approach allows companies to make an appropriate contribution to the overarching goal of limiting warming to less than 2°C.

    Screen Shot 2017-05-20 at 8.25.11 PMContext-Based Water Targets, therefore, recognise the physical and social thresholds of the relevant river basin and track water use relative to the basin’s thresholds/availability and its alignment with public policy and other water goals.

    One example might be a facility’s water use goal developed as a fair share of the basin’s water resources.  One of the challenges is determining fair share allocation, which is typically set by the public sector considering multiple variables including environmental flows. By using each basin’s unique conditions to inform targets, companies can establish performance targets that contribute not only to public policy objectives, but also to a basin’s water risk reduction. This approach helps companies effectively mitigate water risk and secure sustainable clean water supplies.

    Value of Setting Context-Based Water Targets

    Developing a common approach to context-based water targets  will offer value to both companies and their stakeholders by addressing:

    • Existing integrated basin management priorities and goals – Water stewardship targets are most effective when established in a social, economic, environmental, and political context in which food, energy, water, and ecosystem security for all is in balance.
    • The local basin context – Meaningful targets are more sustainable when founded in scientific understanding as well as in the socioeconomic, political, and hydrological context to ensure sustainability. It is also more sustainable when possible targets align with ongoing public policy dialogues and company initiatives.
    • The multi-issue nature of water – Water stewardship outcomes tend to be more lasting when they align with the six areas outlined in Sustainable Development Goal(SDG) 6, consider linkages to the water-food-energy-ecosystem nexus, and drive social and economic development within local contextual constraints.
    • Equitable allocation methods rooted in good water governance – The attainment of corporate-based water targets (CBWTs) tends to be more successful when (1) informed by the sustainability of the basin and the company’s share of responsibility, and (2) tied to notions of good water governance and other shared basin goals. Arriving at shared goals and responsibilities may be formal or informal, but it is central to basin sustainability.
    • Data constraints and needs – Data remain a critical element in any context-based target approach. Any proposed approach tends to be more effective when based on a realistic assessment of what data is available for all stakeholders in the near-term, as well as, when possible, ongoing links to data monitoring systems and sharing water data.
    • The need to be company-relevant – CBWTs tend to be more effective when they are applicable for company decision-making and corporate strategy, including scenario analysis and horizon planning, and when they tie back to actual water risk and investor concerns. Target setting must be supported by measurable, meaningful, and pragmatic methodologies for companies across a full value chain, from raw material sourcing all the way to consumer product use.

    How can Companies Develop Context-Based Corporate Water Targets?

    Companies can develop more impactful corporate water targets by considering the basin’s local context, including a scientific foundation, aligning with public and private sector initiatives, and involving stakeholders.

    Screen Shot 2017-05-20 at 8.25.20 PMThis is shown through WRI’s work with Mars who identified science-based corporate targets to track the company’s progress. WRI recommended using a scientific foundation of total water withdrawals within the watershed that should be at or below 40 percent of the annual average renewable available supplies as identified by the UN water stress scale.

    Local engagement with government and river basin stakeholders was required to understand the specific targets for each watershed and the percentage of reduction of water users based on sector (e.g., domestic, industrial and agricultural). Thereafter, Mars established watershed targets to reduce the fraction of water withdrawals that are in excess of 40% of renewable supplies. Other useful company examples are laid out in the blog, “Thirsty for Change: 4 Way to Improve Corporate Water Targets.”

    Screen Shot 2017-05-20 at 8.25.31 PMWe recognise that a shift to context-based water targets will not occur overnight. Furthermore, we recognise that these changes are not starting from scratch; companies have a long history of working on water issues in context and, indeed, acknowledging context in their water targets.

    We believe that a continuum of approaches (see image below) will likely be required as companies shift from contextual to stronger forms of context-based water targets that include more robust, consensus-driven processes.



    Currently, we are looking for companies that are interested in pilot testing the Context-Based Water Targets approach or to participate in the Advisory Committee or the Stakeholder Consultation Group.

    Don’t you think it is time to join this important and timely endeavour?

    Thirsty for Change? 4 Ways to Improve Corporate Water Targets

    By Paul Reig, Morgan Gillespy, Tien Shiao, Kari Vigerstol and Alexis Morgan

    Context-based water targets slider cropped


    Water-related business risks are becoming more and more apparent. According to CDP’s 2016 global water report, 607 companies lost $14 billion last year alone due to water scarcity, drought, flood and other water risks.

    Current methods for creating corporate water stewardship targets—which often ignore the unique local context of water issues—are inadequate. For companies to succeed as water stewards, they need a new generation of targets. Such targets—based on the local context and guided by the best available science—would help ensure long-term business growth in the face of increased competition and depletion of water.

    That’s why CDP, the UN Global Compact CEO Water Mandate, the Nature Conservancy, the World Resources Institute and WWF are calling for a new approach to setting corporate water targets. Our discussion paper launched today makes the case for setting context-based corporate water targets. Here are four considerations for companies looking to create more impactful water stewardship goals:

    1. Local context matters—a lot.

    Modern drinking fountains chill and filter water, and let users fill water bottles (Photo: Peter Gleick 2011)

    There is strong bipartisan support for expanding investment in the nation’s water infrastructure as part of a broader infrastructure effort. But there is, as yet, little agreement about what specific investments should be made. Here is one idea: expand access to high-quality and safe municipal water by improving access to drinking fountains in schools, parks, public buildings, and around public transit areas.

    Drinking fountains are an important public resource, serving as an alternative to bottled water or sugary drinks and accommodating a wide array of users, including children, commuters, runners, the homeless, and tourists. Some fountains are even designed to provide water for pets. A newly released study from the Pacific Institute, entitled “Drinking Fountains and Public Health: Improving National Water Infrastructure to Rebuild Trust and Ensure Access,” discusses the state of the nation’s drinking fountains and addresses concerns about their quality and links to illnesses. The report concludes that the risk of fountain water contamination can be reduced or eliminated altogether through improved maintenance and cleaning or updating and replacing old water infrastructure and pipes. …»

    Among the different professional categories, scientists and engineers remain very highly respected by the public, at least compared to politicians, business leaders, the media, and even religious authorities. Part of this is due to the fact that success in the scientific enterprise depends on impartial analysis and independence from political ideology. And yet there are strong connections between science and policy: good policy without good science is difficult; good policy with bad science is impossible. Sure, there is plenty of bad policy made even in the face of contradictory scientific evidence, but that is the result of political failures, or, at times, poor scientific communication.

    A perennial question facing scientists is when — and how — to participate in public communication and policy debates around issues of social concern. This is not a new question: as long as scientists have seen a connection between their work and major challenges facing society, some have acted on a sense of responsibility to contribute to debates about how science can be harnessed to improve the world. Scientists have little political power: they are small in numbers, rarely sufficiently financially wealthy to use money as a political tool, and often politically naïve or poorly networked.

    National Geographic Presents: Water Scarcity

    By Peter Gleick, President-Emeritus and Chief Scientist

    October 27, 2016

    The reality of climate change, driven by the fossil-fuel industrialization of the planet, is upon us. Scientists have known for decades of this risk and have, with increasing urgency, tried to alert the public and policy makers about the threat and the opportunities to reduce that threat, to little avail. And now, we must live with unavoidable consequences, even as we continue to work to reduce the emissions of climate-changing gases.

    Among those unavoidable consequences are widespread impacts on freshwater – perhaps the most important resource for human and ecological well being, economic productivity, and global security. Water is a renewable resource, and vital for all the things we want to do. The hydrologic cycle of evaporation, condensation, precipitation, runoff, and back to evaporation provides life-giving rains for crops and forests, generates the runoff we see flowing in our rivers and streams, and refreshes the oceans that are the nurseries for much of the life on the planet.

  • 21st Century Water Demand Forecasting

    By Matthew Heberger, Senior Research Associate and Heather Cooley, Water Program Director

    August 31, 2016

    Yogi Berra once said, “It’s hard to make predictions, especially about the future.” And nowhere is this more true than in the water business. Forecasts are extremely important for water utilities, which must make plans today to meet their communities’ current and future water needs. Since water supply projects can take years to plan and build, utilities’ long-term view often reaches twenty years or more into the future. But the industry has a poor track record when it comes to long-range forecasting.

    The results of this are not purely academic. The end result is that water utilities may build unneeded or oversized water supply and treatment infrastructure – things like reservoirs, pumping stations, treatment plants, and desalination facilities – passing on the costs to customers and creating unnecessary environmental impacts. …»

    U.S. Bottled Water Consumption on the Rise: What Does It Mean?

    By Rebecca Olson, Communications Associate

    July 21, 2016

                           Steven Depolo

    If last year’s bottled water sales are any indication, the sale of bottled water in the U.S. this year will likely surpass that of soda. In 2015, Americans bought the equivalent of five bottles of water per citizen each week. Meanwhile, the sale of soda fell 1.5 percent, reaching the lowest level per person since 1985.

    While there is a positive side to this picture — certainly water is a healthier beverage to consume than sugary carbonated drinks — the consumption of bottled water has negative environmental and economic repercussions, as outlined in Peter Gleick’s 2010 book Bottled and Sold: The Story Behind Our Obsession with Bottled Water. As Gleick explained, each bottle of water is the product of a vast amount of energy and contributes to plastic waste. …»

  • ERW Opinion: On Methods for Assessing Water-Resource Risks and Vulnerabilities

    By Peter Gleick, President Emeritus and Chief Scientist

    July 29, 2016

    Much more can and should be done with new data and methods to improve our understanding of water challenges, says Peter Gleick.

    As populations and economies continue to expand and as anthropogenic climate change accelerates, pressures on regional freshwater resources are also growing. A wide range of assessments of water pressures has been produced in recent years, including the regular updates from the United Nations World Water Development Reports (WWAP 2003, 2006, 2009, 2012, 2014, 2015), the biennial assessment The World’s Water (Gleick et al 1998–2015), the Aqueduct water stress datasets produced by the World Resources Institute (WRI 2015), and numerous other efforts to develop quantitative water measures and indices. The development of such methods has become increasingly common in recent years in order to help measure progress and evaluate the impacts or effectiveness of water policies and practices. The new letter in this volume of Environmental Research Letters by Padowski et al (2015) offers another opportunity to evaluate freshwater threats and vulnerabilities.

  • Diablo Canyon Nuclear Power Plant, courtesy PG&E

    National Geographic ScienceBlogs: Diablo Canyon, Climate Change, Drought, and Energy Policy

    By Peter Gleick, President Emeritus and Chief Scientist

    June 24, 2016

    The announcement that Pacific Gas and Electric (PG&E) will close the Diablo Canyon Nuclear Plant when its current operating licenses expire in 2025 has caused what can only be described as consternation mixed with occasional conniptions among the nuclear industry and some strongly pro-nuclear groups.

    That’s understandable. Diablo Canyon is aging, but is not the oldest nuclear plant in the fleet and PG&E could have chosen to push for a renewal of the license to continue operations for many more years. Diablo Canyon’s two reactors are also California’s last operating nuclear plants, following the closure many years ago of Rancho Seco near Sacramento, and more recently, the last of the San Onofre reactors. As such, the closure is symbolic of the broader woes of the nuclear power industry in the United States, which has been unable to build new reactors and is seeing the current reactors being shuttered, one by one.
