By installing more efficient water fixtures and regularly checking for leaks, households can reduce daily indoor per capita water use to about 45.2 gallons per day. Here's how it breaks down for households using conservation measures:
|Type of Use
||Gallons per Capita

If all U.S. households installed water-saving features, water use would decrease by 30 percent, saving an estimated 5.4 billion gallons per day. This would result in dollar-volume savings of $11.3 million per day or more than $4 billion per year.
Water-conserving fixtures installed in U.S. households in 1998 alone have saved 44 million gallons of water every day, resulting in total dollar-value savings of more than $33.6 million per year.
