Yet total water withdrawal has not followed the same trend. Water withdrawal was on the rise until 1980. It stabilized for the next 25 years, but saw a dip in 2010. Is this a good sign? Does it signify an increased adoption of water conservation measures by citizens for domestic use? Or was there adoption of water restrictive alternatives in different sectors?<\/p>\n<h3>Demand by Sector<\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-426 size-full aligncenter\" src=\"https:\/\/www.ntotank.com\/blog\/wp-content\/uploads\/2016\/11\/PopulationvsWithdrawal-1.jpg\" alt=\"Sector Distribution\" width=\"679\" height=\"567\" srcset=\"https:\/\/ntotank.com\/blog\/wp-content\/uploads\/2016\/11\/PopulationvsWithdrawal-1.jpg 679w, https:\/\/ntotank.com\/blog\/wp-content\/uploads\/2016\/11\/PopulationvsWithdrawal-1-300x251.jpg 300w\" sizes=\"(max-width: 679px) 100vw, 679px\" \/><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-427 size-full aligncenter\" src=\"https:\/\/www.ntotank.com\/blog\/wp-content\/uploads\/2016\/11\/OverallSectorWithdrawal.jpg\" alt=\"overallsectorwithdrawal\" width=\"571\" height=\"476\" srcset=\"https:\/\/ntotank.com\/blog\/wp-content\/uploads\/2016\/11\/OverallSectorWithdrawal.jpg 571w, https:\/\/ntotank.com\/blog\/wp-content\/uploads\/2016\/11\/OverallSectorWithdrawal-300x250.jpg 300w\" sizes=\"(max-width: 571px) 100vw, 571px\" \/><\/p>\n<p style=\"background: white;margin: 0in 0in 21.0pt 0in\">The two major water consumers are the thermoelectric power and irrigation sectors. They amount to almost 80% of the total demand. Both are on a gradual downward trend after their highs in 1980. Is water withdrawal for irrigation decreasing due to a drop in demand? Or is it because of better water management in irrigation?<\/p>\n<p style=\"background: white;margin: 0in 0in 21.0pt 0in\">Downward trends in water requirements for the thermoelectric power sector may be due to the shift towards using renewable energy sources.<\/p>\n<p style=\"background: white;margin: 0in 0in 21.0pt 0in\">Contrary to the behaviors shown by thermoelectric power and irrigation, the public supply sector \u2013 which takes care of domestic consumption- has steadily increased withdrawals. There has been a 100% withdrawal increase from 1960 to 2010. This has a positive correlation with the increasing population.<\/p>\n<h3>Source mix<\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-430 size-full aligncenter\" src=\"https:\/\/www.ntotank.com\/blog\/wp-content\/uploads\/2016\/11\/SourceDistribution-1.jpg\" alt=\"sourcedistribution\" width=\"680\" height=\"569\" srcset=\"https:\/\/ntotank.com\/blog\/wp-content\/uploads\/2016\/11\/SourceDistribution-1.jpg 680w, https:\/\/ntotank.com\/blog\/wp-content\/uploads\/2016\/11\/SourceDistribution-1-300x251.jpg 300w\" sizes=\"(max-width: 680px) 100vw, 680px\" \/><\/p>\n<p style=\"margin: 13.2pt 0in 13.2pt 0in\">Surface water sources have proven to be the\u00a0dominant withdrawal source.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-429 size-full aligncenter\" src=\"https:\/\/www.ntotank.com\/blog\/wp-content\/uploads\/2016\/11\/OverallSource.jpg\" alt=\"overallsource\" width=\"571\" height=\"427\" srcset=\"https:\/\/ntotank.com\/blog\/wp-content\/uploads\/2016\/11\/OverallSource.jpg 571w, https:\/\/ntotank.com\/blog\/wp-content\/uploads\/2016\/11\/OverallSource-300x224.jpg 300w\" sizes=\"(max-width: 571px) 100vw, 571px\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>Reference:<\/p>\n<ul>\n<li>http:\/\/waterdata.usgs.gov\/nwis\/wu<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>How much water does the United States of America consume on an annual basis?
