Filter System Solution for Collapsing Well

Hello David,

Thank you for contacting us through our website.  You wrote: 
“Have an inn in NY, well started sucking air & getting air hammers in faucets/toilets. Called plumber, he diagnosed well needed to be "hammered" (done the next day), problem tho, it's a gravel well. So hammer did nothing positive.
Real problem was broken (frozen) water pipe, out the back of house, feeding a trailer home, & blowing 3,000 gal water a day. 3/4 hp Variable speed pump was able to disguise the problem. Capped leaking pipe, well is slow recovery now, and has sand/silt that won't seem to go away. Plumbers' solution is/has been, drill deeper! Or New Well.
Gotta be another solution...?”

You can definitely get clean water and filter out the sand and sediment.  In some cases however, if your well is collapsing, or silting in, or filling in with sand, it can be a losing battle.  But we have had many customers over the years continue to use their wells for years with treatment systems in place.  If you  ever did have to replace your well, you can continue to use the filters for good measure.

Because it is a variable speed pump, centrifugal sand separators don’t work that well.  We would recommend a settling tank using an 80 gallon contact tank, followed by a Sediment Trapper, then a Sediment Backwash Water, followed by a 25/1  20” big blue filter. If there is still turbidity or cloudiness after that, we recommend a UF membrane as a final filter.

Tank, Contact Mixing 80 Gallon, 21” Diameter X 72” Tall                  

Unlike Well Mate contact tanks rated for 75 PSI max, this tank is rated for 125 PSI.  1-1/2 inch inlet and out at TOP, plus DRAIN at bottom makes installation fast and easy.  These lightweight seamless totally non-corrosive retention tanks are ideal for new and replacement installation where durability is at a premium.

Features:  100% non-metallic polymer materials, impervious to chemical attack.  Choose 1", 1-1/4" or 1-1/2" threaded in-out connections for top.  Drain:  2" slip PVC at bottom.  No drain valve included, but is easy to set up with 2" PVC available from any plumbing supply or home depot store etc.  Easy installation and unmatched durability.
