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 five times a day, which is about 8 gallons flushed, which rounds out 1,825 flushes a year. That equals 2,920 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 876 gallons of water, saving a considerable amount of water and money a month and year.
