    Which is better for open loop discharge...recharge well or drywell?

    Valveman, Thanks for bringing in the maintenance perspective of things. So if either method stops accepting water then a recharge well should be easier to maintain (or replace) than a large drywell pit? The water in this area typically has little iron, sulpher, etc., however it does have...

    Which is better for open loop discharge...recharge well or drywell?

    Situation and a need for quick assistance: I'm currenty installing a geo system with a well-water sourced open loop. I have a choice of a recharge (dump) well or a really big french drain/drywell (plenty of land either way). Cost to drill a well is estimated at $5000 for 200'+-. Cost...

    Water Source Heat Pump Deep Pump Sizing

    A bump from Thump :confused: It's getting [too close] to time and pull the trigger and I'm seeking input on which way to go on the recharge well direction/reinjection pipe length questions posed in my last post in this thread. Thanks, T

    Water Source Heat Pump Deep Pump Sizing

    I've been reading this thread with great interest as it touches on most of the things I am trying to do in this thread: [URL="https://terrylove.com/forums/showthread.php?t=27993"] One of the things I can't figure out is just how far down into the recharge well can the return pipe really go...

    Need help with Alternate Method of pumping in two-well "pump & dump" systems?

    Bill, thanks for the constructive input. After reviewing more about the water-to-gas state Bill mentioned and outgassing issues of water at low *negative* pressures (in this case 27+- ft. @ 5000' elevation) it seems that returning the water at a low elevation to recover pump energy is...

    Need help with Alternate Method of pumping in two-well "pump & dump" systems?

    NHMaster, I'm not sure what your saying here. Are geo systems as a class not economical to install or operate? Too difficult to implement and frought with excessive maintenance issues? Rich boy I'm definnately not...we have to get it right the first time! I agree that the efficency...

    Need help with Alternate Method of pumping in two-well "pump & dump" systems?

    Hi Guys, thanks for the responses. Bill I was under the impression that the weight of the water column in the supply well pipe would be mostly offset by the suction created by the pipe dropping/returning the water to the recharge well as long as the return pipe was long enough to always be...

    Need help with Alternate Method of pumping in two-well "pump & dump" systems?

    I have combined the following two posts from "Green Building Talk" into this thread in hopes of obtaining some expertise or direction. I am building in the coming months and am willing to experiment IF the science is solid. Proposed is a two well (source and recharge) geo setup. This is a...
