purpose of a retention tank

[starks]

Can someone please help me with a question about retention tanks. Whats the purpose? Is it so you always have water stored? Or is it so the pump doesnt have to kick on so often? We currently have to replace our pump. We pump out of a pond about 110ft all vertical. To a heated room thats in the barn. We have had consultations from various water treatment companies and they always said we should have at least 2 retention tanks. We always ended up going the do it yourself way just because we didnt want to pay their prices. They are really behind ultraviolet light technology also, I think they dont like it because theres no salt or chemicals to deliver to you every other week. Thanks in advance, I am interested in a retention tank if it will save on my electric bill at all. Thank You starks

Retention tanks are usually used with chlorinators to allow the proper "contact time" for the chlorine to do it's job. They have nothing to do with the electric bill. Are you pumping out of a pond for potable water? If so I can see why they where talking about retention tanks and ultra-violet lights.

Yes that make sense. Our current filter system can work at 13 gallons per minute. It has worked fine for 8 months with out a retention tank. I figured it was something to look into while I was already having to change the pump. Thanks for your help.
