We've all heard the saying, “If it's yellow let it mellow, if it's brown flush it down,” but can limiting your flushes really save you money? It sure can, and it conserves water — but how much water and money you save really depends on how stingy you are with the flushes.
Let's do the math: The average person urinates six times a day, which is about 7.6 gallons flushed. That equals 2,774 gallons per year to dispose of just 171 gallons of urine. The average person defecates about once per day, and if that were the only occasion you flushed, it would equal 584 gallons of water, saving 2,190 gallons. If a household of four followed this flushing rule, they would save 8,760 gallons of water a year.
