National Mayor's Challenge for Water Conservation

Mayors/City Officials! The national challenge for water conservation is back for its 6th year. Does your city have what it takes to win?


The Wyland Foundation's Annual National Mayor's Challenge for Water Conservation held every Earth Month (April 1-30) is a competition that encourages cities across the nation to see who can be the most water wise by asking their residents to take a series of informative, easy to use pledges online to conserve water, energy and other natural resources. The non-profit campaign is presented nationally by Toyota and the Wyland Foundation, in association with NLC, EPA Office of Water, U.S. Forest Service, the Toro Company, Bytelaunch, Inc., Wondergrove Kids, and mayors and water agencies across the country.

With 2017 being its sixth year, the challenge has become widely recognized as one of the most engaging, zero-cost outreach tools especially designed for cities and water utilities to encourage conservation in the United States. As a leader, your participation helps conservation-minded residents of your city win over $50,000 in eco-friendly prizes including a 2017 Toyota Prius Prime, water-saving home products, home improvement gift cards and more. 

Complete the form on the right to show your support and you will receive additional information, promotional materials, and ideas for making the challenge a success in your city.

About the Program

Whether it's drought conditions in the West or the high costs of energy related to water use in the East, saving water has become one of the most talked about issues in the nation today. The National Mayor's Challenge for Water Conservation was created to reward residents for positive conservation behavior, provide immediate feedback with real time city by city results that can be measured against their neighboring cities, set goals to promote positive changes in consumer behavior and put a spotlight on public role models to encourage behavioral change.

The overall campaign is designed to:

  • Save costs for consumers
  • Save infrastructure and operating costs for cities
  • Promote drought resiliency
  • Protect watersheds and ecosystems

Moreover, residents also learn about resources in their area to take their commitment of conservation even further, from regional water and energy resource issues, to cost-saving tips at home. As part of the program, city staff can do as much or as little as their time allows. Either way, by simply being involved and committing to the Challenge, you’re leading your city’s residents to take the necessary steps to become better-informed and more active stewards of the community and our natural resources.

How It Works

  1. Residents go to www.mywaterpledge.com
  2. Take a 4-step conservation pledge on behalf of the city
  3. See city's current standings
  4. Encourage their friends to take part

The city with the highest percentage of residents who take the challenge in their population category wins. Cities will compete in the following population categories for 2016:
  • 5,000 - 29,999
  • 30,000 - 99,999
  • 100,000 - 299,999
  • 300,000 - 599,999
  • 600,000+
Participants in the winning cities are eligible to win hundreds of prizes. Last year, the challenge awarded more than $50,000 in prizes to nearly 1,000 residents in U.S. cities. Most importantly, participants see the enormous impact they can have on their community by taking simple actions to save water and energy.

City Prize! Pocket Park Landscape Makeover

One winning city from the 2015 challenge will be chosen at random to receive a pocket park landscape makeover, including state of the art water efficient irrigation from the Toro Company.

2014 winner Dallas, TX received a new water efficient outdoor classroom at Nancy Cochran Elementary School. The project broke ground on April 9 with Dallas Mayor Mike Rawlings and EPA Administrator Gina McCarthy. The interior courtyard at the school was refashioned with Texas native trees, plants and grasses, decomposed granite pathways, low-cost water efficient irrigation and weather sensors, and student gardens for each grade.
Texas Land Care of Dallas and the Toro Company contributed installation services and irrigation, respectively, with underwriting for the project from the Wyland Foundatoin, Toyota and a grant from Melody and David howell. The school can expect to save over 250,000 gallons of water a year versus a conventional irrigated lawn area of the same size.

Why Your City Needs To Get Involved

  • With no costs to cities or tax-payers, the Mayors Challenge offers a compelling, positive way to motivate residents to conserve water and energy resources.
  • Creates a legacy for you and your city by reaffirming your commitment to protecting natural resources and reducing your city’s “water footprint.”
  • Recognizes and rewards your residents who are committed to making a difference in your community. Residents can save money, help your city meet conservation goals, discover water-related issues affecting your region — and earn a chance to win water-saving prizes – including a Toyota Prius.
  • Ties in with state and national water, energy, and GHG management plans, such as California's AB32 or Texas' SB 184.

2016 Highlights and Results

  • The cities with the highest percentage of residents making pledges during the campaign included Boston, Mass., Aurora, Colo., Ventura, Calif., Andover, Minn., and Laguna Beach, Calif.
  • Residents around the nation, from Anchorage to the Florida Keys, made 404,407 pledges to reduce water waste by more than 1.9 billion gallons — or roughly enough water to fill 2,877 Olympic-sized swimming pools.
  • By altering daily lifestyle choices, pledges also resulted in potentially 42 million fewer pounds in landfills. Potential savings of 12 million gallons of oil, 6.1 billion pounds of carbon dioxide, 126 million kilowatt hours of electricity, and $29 million in consumer cost savings rounded out the final pledge results.

2015 Highlights and Results

  • The challenge had direct participation from mayors in 36 states, from San Diego to Miami, Florida, who encouraged their residents to participate
  • The cities of San Diego, CA, Aurora, CO, Torrance, CA, Poway, CA and Hermosa Beach, CA, led an effort among over 42,000 people across the nation to take 391,325 specific actions over the next year to change the way they use water in the home yard, and the community - a 30% increase over 2014.
  • By sticking to their commitments, the collective efforts of these residents will reduce national water waste by 1.5 billion gallons, reduce waste sent to landfills by 47 million pounds, eliminate more than 141,000 pounds of hazardous waste from entering our watersheds and save 139 million kilowatt hours of energy.

Mayor's Message

Mike Rawlings, Mayor of Dallas, Tx

The County of Hawai’i recognizes the precious nature of our water resources, and strongly supports water conservation initiatives. Our County water utility, the Department of Water Supply, is participating in the WaterSmart program, which strives to educate consumers in the wise use of water. The online program provides water-saving tips and messages tailored to customers in the drier West Side of our multi-climate island. The motto of our Department of Water Supply, “Ka Wai A Kane,” (“Water, our most precious resource”) expresses very well the deeply-understood importance of protecting and conserving the life-giving water with which we are blessed.

Harry Kim, Mayor of Hilo, HI

Grand Rapids is home to Michigan’s largest watershed – the Grand River, which runs through our downtown. That, coupled with our close proximity to Lake Michigan, we recognize the importance of protecting our fresh water resources. I encourage all citizens to join me in this pledge. Your small choices, when multiplied again and again, make a significant difference in ensuring our city’s sustainability for generations to come.

Rosalynn Bliss, Mayor of Grand Rapids, MI

Conservation is an integral part of the City of Aurora’s water planning and management of this most precious resource. With the ever increasing demands on limited water resources, the National Mayor’s Challenge for Water Conservation has underscored our residents’ commitment to the ongoing sustainability and conservation of our water. Aurorans have really stepped up to win this challenge two years in a row. We’re looking forward to our third victory this year.

Steve Hogan, Mayor of Aurora, CO

The City of Dallas values water conservation efforts, which is why we are continuing to participate in the National Mayor’s Challenge for Water Conservation. Conserving water is a critical piece in securing resources for generations to come and our residents understand the importance of this effort. Continuing this effort will enable residents to conserve and protect our water resources.

Mike Rawlings, Mayor of Dalls, TX
