“We never know the worth of water till the well is dry.”

~ Thomas Fuller, Gnomologia, 1732

Residential water use includes water used indoors (bathing, cooking, cleaning, etc.) and water used outdoors (watering plants, swimming pools, washing cars, etc.) In Arizona, about 25% of the water supply is for municipal use, and most of this is residential. Each person uses about 100 gallons per day, and as much as 70% of that water is used outdoors, especially in summer. Residents that incorporate water efficiency into everyday life will help to preserve water for future generations.

The following information is designed to help Arizona residents use water wisely and efficiently indoors and out.

• Indoor Residential Conservation
• Outdoor Residential Conservation
• Graywater and Rainwater Harvesting

Efficient water use can have major environmental, public health, and economic benefits by helping to improve water quality, maintain aquatic ecosystems, and protect drinking water resources. Efficient use of water, through behavioral, operational, or equipment changes, if practiced broadly can help mitigate the effects of drought.  ADWR's Water Conservation Tips for Arizona Residents (72 KB) provides general water saving ideas for outside and inside the home.

Estimate your daily and annual water use with the Water Calculator. Answer a few simple questions and the Water Calculator does the rest. It's quick and easy. The calculator is part of "homewaterworks", a project of the Alliance for Water Efficiency.
