Off-grid pump for 250' deep well?

We used a barrel filled with charcoal and let the rainwater off the roof filter through it. It worked great, and we only changed the charcoal about every 5 years, though I have no idea how hard it would be to get real charcoal any more.

The downspout went right into the top of the barrel. The bottom of the barrel was plumbed (3"pipe) directly into the cistern which was built of concrete. The top of the cistern was our front porch.

I don't know how to set it up but I seen Water Pumped from Deep Well using Air compressed using a Small Gas Engine, filling a Large old Propane Tank with Air.

Actually looked like a simple set up.

I did that very thing for the first several years. I now have a solar system big enough to run my pump and fill the cistern, using the generator only as backup. It worked/works great both ways. My pump pulls about 2600W continuous, so 3500-4000 Watt generator would do the trick.

What kind of tank did you bury? Steel or plastic? Thanks.

I take it you're pushing at least a 2HP at 230V? What's the surge on your genny and make and model? I'm in a similar situation and would like to get your recommendation on that genny. Thanks.

I have the SQFlex Grundfos which is expensive but worth every dime. I also have tried the Simple Pump but with less than stellar results from both the pump and the gearmotor. The Simple pump people didn't stand behind their products either. While others have had success with them, I however did not.

The SQFlex is a great flexible solution to your water pumping needs. It runs off AC or DC and has a big voltage range . It can run direct off solar only when the sun is shining or the wind is blowing into a holding tank. It can also run straight off your generator when needed. I am not sorry I took the plunge and purchased this pump. My well is 300' with a static water level at 200'. The professional installers set the pump at 240'.

Just a reminder. Well depth and water table depth are two separate situations. Just because you have a deep well depth often has little to with the pump requirements of the pump. I have a well that is 780 ft deep and the replenish rate is only ~3 gallons per minute. The water table is ~34 ft. I have the submersible pump set at ~200 ft. It took 3 tries with the well machine to get this water and it provides water for 5 homes. The casing gives plenty of storage and a 3/4 HP pump provides the pressure and moves the water up to 500 ft plus. All of the water users are happy and this setup has been supplying water for ~ 20 years. Matching your pump to your particular situation is possibly more important than the depth of the well. Get your specs for the well and match your pump to where the water static level exists.

Wow over 700 feet of storage. Didn't that cost you a ton ?

Yes it was expensive. I had already tried 2 other locations on the property with zero water results. There was no choice but to continue with the drilling if I wanted water.
