Hello Folks,
I am in Central Wi. I have an off grid cabin. I have the well drilled. Water table is at 11ft (kinda swampy near the property), well depth is 60ft. I am am on solar with a generator back up. My plumber is conventional and not used to identifying low wattage off grid systems. I am looking for 1) a low watt well pump and 2) good water filter. Water filter is important due to the high water table. I have a hand pump now, and it is nasty when if comes out for the first several galllons. My system will be the well pump, then the filter, then a pressurized water tank. Any suggestions are appreciated.

What voltage of pump - 12V or 120V? They do make submersible pumps in both voltages. Search Amazon. But, given a well depth of 60 ft., I believe submersible is the only way to go.
As far as filters are concerned, are you wanting to be able to drink the water, or just clean it up to where you can use it for everything else?

We looked at a lot of options. Even installed a r/o system before removing it.
The best solution we found was a berkey style gravity filter. (We use dalton)Use the pump to fill it up and let gravity filter the water in 3-4 gallon batches. I forget the specs but Ceramics filters filter down to a very small amount- where giardia and all the bad stuf can’t get through.
We use a10-15 micron sediment filter and then pump to our berkey style filter.

They do make UV filters too. You would need to filter it then run through a UV filter.
I use a berkey style filter now and when I build a real system wont be including one of them as I will want all water potable not just from that.

I have a 220v pump 50’ underground, an old gas generator up top dedicated to it in the well shack, goes 200’ uphill to a 500 gallon above ground (and cabin) tank, feeds an old pool filter next to it with washable/replaceable element, gravity feed to the cabin with DC pump for high pressure if needed. Could add a filter in cabin if needed but water is always clear and tasty. Going on 10 years like that.

MimiInWi For what it’s worth I did a lot of research and couldn’t really find any
thing that looked like a great option for an in-line filter. Reverse osmosis or the “berkey style” were the best solution I could find. I would be interested to hear about your experience and what you find.
The problems as i recall were either reduced flow rate or the lack of an “absolute” appropriately sized filter. As you get into filters you will find “absolute” size is rare. What that means is that the filter size will NOT let anything through that is bigger than the size mentioned. If it doesn’t say “absolute” it’s essentially an average of the pore sizes in the filter-meaning bad stuff can still get through. This isn’t a big deal if it’s just a sediment filter but for filtering out giardia and viruses it’s essential.

Quoting: Grizzlyman r filtering out giardia and viruses
UV kills both of those. You just need to filter it enough to not shadow out any bad things. I use a carbon filter for this.
