"Don't even talk to me about reverse osmosis" said the woman on the telephone. "They waste too much water and I want to be conservative with our water resources!"
That is something I hear quite frequently and frankly, I don't understand it. Oh, I understand wanting to be conservative with our natural resources, but that same woman was driving 7 miles to town and back to get bottled water which probably was made by reverse osmosis anyway! Let's pollute the air and waste fossil fuel, but dad-gumitt, I won't waste a drop of precious water! Of course that is crazy, but let me put this in perspective. A reverse osmosis system wastes about 4 gallons of water per gallon made. If you use 3 gallons a day for drinking, cooking and internal consumption, that means you will waste about 12 gallons, making a reverse osmosis system about 25% effecient! However, US Water Systems are able to reduce water waste by up to 80%
Is that bad? Like I said, let me put it in perspective. Do you have a washing machine? Do you have a dishwasher? Why do you have a washing machine and dishwasher? Well, obviously it's to get your clothes clean and to get your dishes clean and sterilized. How efficient is your washing machine? A reverse osmosis system is 25% efficient. A washing machine and dishwasher uses electricity and hot water (which takes energy to heat) and WASTES EVERY GALLON OF WATER THEY USE.
A reverse osmosis system is not nearly that wasteful - no electricity and no wasted energy with heated water. You have a washing machine to get your clothes clean. You have a dishwasher to get your dishes clean. You think nothing of wasting water and energy to get your clothes and dishes clean, and yet you don't want a reverse osmosis system that is 25% efficient to get your water clean? Are you nuts? How long can you live without clean clothes? You might stink, but it won't kill you! How long can you live without clean dishes? You get the picture? Your body uses water to cool it and eliminate waste, but you are unwilling to waste a little water to clean your water for internal consumption? The water you drink sustains your life? You'll waste water to clean your clothes and dishes, but not to clean your water? You must be kidding!
