Having a deep well ..250'..I have a false sense of security in clean safe water. I realize our generator would need to be used to pump it up for use if not electric available...but would it be safe and uncontaminated?? What do you all think. ??
our well is 220' . It has muddied once in the 20 years we have been here (we drilled the well). It is possible for it to become fouled. As others have mentioned, a rope, pulley and well bucket are necessary to use in a power outage, and clorox bleach to shock the well.
I'd rather have one Chewbacca than an entire clone army.
Although not common, it's quite possible for a well to become contaminated with anything from surface water to fracking fluids to naturally occurring minerals. That's one issue.
Your ability to get water from over 200' below is now dependent on electric power. That separate issue revolves around how long could you generate power if the grid went down and was gone a long time. Yes, you 'could' use a rope and well bucket, but when you think about it, how practical is it to replace your current water needs with a hand drawn bucket ? While you could probably get enough to drink, you SURE aren't gonna be taking a shower, flushing toilets or washing clothes that way unless somebody's full time job is hauling water up a gallon or two at a time.
I don't know how realistic this is for your situation, but I love a water system that doesn't depend on electricity at all. Our water supply is gravity fed from the creek. Yes, it could be polluted, but we do have two large water tanks with about 40,000 gallons storage.
I love what Dorothy Ainsworthdid at her place in Oregon. She has a well, and a water tank she built herself. She has an old fashioned windmill. Because of this, she isn't dependent on electricity for her water at all. windmills
What "quality" is your generator . . . ???
Lots of folks have a very false sense of security with their $99.95 Super Duper El Cheapo generators .......
It screams, it pumps some water.....
Then Murphys law kicks in . . . . .a bang, a cloud of smoke, and said Cheapo is now a boat anchor . . . . . . .
I should have added in my above post;
Those cheapo **generators** are notorious for their bad / poor voltage regulation.
It is quite possible for one of those El Cheapos to damage / kill the water pump.........
Now that the cow pie has hit the fan and you have no water . . . . . . . . . . . . .
I really need to find a hand pump that will work to 80'........
solar (PV panel direct) driven water pumps are another option for the deep well. they don't pump alot of water fast, but a gallon or so a minute over several hours a day adds up fast.
I would suggest multiple options for water. Add in a cistern (below or above ground) sealed water tank that can be filled from either the well or rain-catch. Have a sand filter on hand to pre-filter the water and a ceramic filter to use for drinking water.
The shallow well (~20-25') would also be a good option if you have the right situation for it.
Get yearly water tests to make sure you don't have a problem. I would opt for a hand pump over a bucket, rope and pulley as a backup to your genny backup. Keeping the well sealed helps keep outside contaminants (think bird poop, etc) from getting into the well. Also, stock bleach for "shocking" the well.
I had a well drilled this year on our farm and will put in solar for the well pump next month. It is expensive but I've scrounged components from local solar suppliers that were reducing inventory or had overstocks. I plan to install a hand pump as a backup but that will have to wait until next year. Luckily the well's static water level is 25 feet with a 25 gallon per minute recharge rate so my hand pump will not need to go to deep.
I don't worry about water-300'well-exc diesel gen-no risk of contaimanation with hand pump for backup....and our old 50' shallow well that we sterilize every year.Recently bought 4-250g water storage barrels so we can fill and use those rather than use gen/well daily.
Watching msnbc is the intellectual equivalent of mutual masturbation by a group of monkeys.
I think if a 250' well is your only water source, you should consider a secondary source. I would worry less about contamination (you can always boil it) than being able to access it without power of any kind. Even hand pumps break.
I went to that Bison site . . . good stuff . . .good way to go . . . . .$1800 .ouch.
Back to the OP; only a geologist can give a studied opinion about the filtering ability of all the different layers of sand / rock / clay etc. etc. for the water working its way down to the water table.
At my place I feel very good that 70' of mostly sand is going to do a darn good job of filtering........
