Colorado, water rights laws almost completely restricted rainwater harvesting; a property owner who captured rainwater was deemed to be stealing it from those who have the rights to take water from the watershed. Now, residential good owners who meet certain criteria may obtain a permit to install a rooftop precipitation collection system (SB 09-080). Up to 10 large scale pilot studies may also be permitted (HB 09-1129). The main factor in persuading the Colorado Legislature to change the law was a 2007 study that found that in an average year, 97% of the precipitation that fell in Douglas County, in the southern suburbs of Denver, never reached a stream—it was used by plants or evaporated on the ground. Rainwater catchment is mandatory for new dwellings in Santa Fe, New Mexico. Texas offers a sales tax exemption on the purchase of rainwater harvesting equipment. Both Texas and Ohio allow the practice even for potable purposes. Oklahoma passed the Water for 2060 Act in 2012, to promote pilot projects for rainwater and graywater use among other water-saving techniques. Water use Domestic water use (also called home or residential water use) in the United States was estimated by the United States Geological Survey at per day in 2005, and per day in 2010 (7 percent lower). The bulk of domestic water is provided through public networks. 13% or of water is self-supplied. The average domestic water use per person in the U.S. was per day in 2005, and per day in 2010. This is about 2.2 times as high as in England (150 Liter) and 2.6 times as high as in Germany (126 Liter). One of the reasons for the high domestic water use in the U.S. is the high share of outdoor water use. For example, the arid West has some of the highest per capita domestic water use, largely because of landscape irrigation. Per capita domestic water use varied from per day in Maine to per day in Arizona and per day in Utah. According to a 1999 study, on average all over the U.S. 58% of domestic water use is outdoors for gardening, swimming pools etc. and 42% is used indoors. A 2016 update of the 1999 study measured the average quantities and percent shares of seven indoor end uses of water: 24% toilets 3% baths 20% showers 17% Clothes washers 1% Dishwashers 19% Faucets 4% Other domestic uses.
