Reverse Osmosis Systems Waste WaterI was asked this question today: "RO systems waster water and I decry waste. Why would I want to use an RO system?" My response is simple, because I am partial to RO: Reverse Osmosis is the singular water treatment process that removes the largest spectrum of contaminants. Translation: If you don't have a reverse osmosis system, you have more contaminants in your water - end of story! You use a toilet to flush your crap away, and that wastes water, why wouldn’t you use an RO to flush the crap in your water away? Think about that one for a minute! Really, a typical RO wastes about 3 gallons for every gallon made. Few people use more than a gallon or two a day, so it is insignificant. You flush a lot more water down the toilet! Commercial-grade high efficiency RO systems are up to 80% efficient (at least ours are). That means that for every 4 gallons they make, they waste just one. Small residential reverse osmosis systems are inexpensive and generally waste 3 gallons for every gallon made, but in the scheme of things, how much is that? I hear people say they don't like to waste water while they run their dishwasher or washing machine or flush their toilet. All three of these devices waste 100% of the water they use, but they improve the quality of people's lives and allow them freedom and convenience. Why isn't the water you drink even more important. Yes, we don't want to waste anything. I get that! So, you could build an outhouse and never waste a gallon of water there, but you still have to wash clothes and dishes, and no matter how you cut it, you are going to have to waste some water. My final question is: If you are going to waste a little water, what better thing to waste it on than the water you drink and the water that sustains your life? Don't be wasteful, but don't be silly either. Drink RO water responsibly... and with a clear conscience! Oh, and by the way, a reverse osmosis system with a permeate pump wastes the least amount of water. Check them out HERE.
