"What is the 40 Gallon Challenge?The 40 Gallon Challenge is a call for residents and businesses to reduce our region's water use on average by 40 gallons per person, per day. The challenge began in 2011 as a voluntary campaign to increase water conservation.
The 40 Gallon Challenge encourages people to save a minimum of 40 gallons a day by adopting new water-saving techniques. The pledge card outlines water-saving practices and the daily water-savings to expect. You can use the pledge to review the water-saving practices that you or your family currently puts to use. By pledging new practices, you will see the total daily savings expected for your household.
The 40 Gallon Challenge also provides maps and charts to see pledge activities in your state and across the United States."
