A drip a second from a leaky faucet sends five gallons of water down the drain in a day. An hour could be measured as 3,364 drips or about 3 3/4 cups of water.
According to the US Geological Survey, a typical drip is between 1/5 and 1/3 of one milliliter. Using 1/4 of a milliliter as an average, the USGS estimates that roughly 15,140 drips from a faucet equals one gallon of water.
In the end, it’s probably easier (and cheaper) to just set the clock ahead for Daylight Savings Time this Sunday.
“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.” – USGS 2015 Water Census
Ellen Swallow Richards is more well known as the Mother of Ecology and founder Family and Consumer Science or Home Economics, but we credit her with modern municipal sewage treatment too.
In 1887, Richards and her associates conducted a water quality study of Massachusetts’ inland waters which were polluted with municipal sewage and industrial waste. This led to the to the first state water-quality standards in the nation and the first modern municipal sewage treatment plant, in Lowell, Massachusetts.
Richards served concurrently as official water analyst for the Massachusetts State Board of Health and as an instructor in MIT’s sanitation chemistry program for ten years, 1887-1897.
