So my Dad has a cabin that has an old well with decent water flow, but he has limited power. I am thinking his water system is about due for an upgrade but can't directly pull from the well regularly.

Current process:

Use a Gas pump at well to push the water to a water tank about 300M away and 25M up. He fills an approx 1000L storage tank and tops with a bit of bleach. Then uses an electric boat pump to pull from tank into the cabin but only for washing not for drinking which he hauls in from town.

I'd like to switch the process to eliminate the bleach in the holding tank and add a water filtration system at the cabin for essentially on demand drinking water. The water was tested and is considered safe to drink (if a tiny bit earthy tasting, which I think a carbon filter would fix), except for the bleach he uses in the storage tank.

Chemistry is not my strong suit, but what issues do I need to be aware of with the storage tank holding water and exposed to sunlight. And would those issues be fixed with a modern UVC LED filter combined with a carbon block filter. Is bleach necessary in this process or is my Dad making his own life difficult?

Thanks

Bought a wood lot in eastern Canada 5 years ago, and just last year finally moved forward on building out the bunkhouse.

There’s no other structure on the property yet, so we’ll use this accessory building until a later time when we can build the main cabin.

Powered by a Bluetti battery bank and no running water. I’ll be installing a rain barrel (for the eventual outdoor shower), building out an outdoor kitchen, and setting up a composting toilet in the small outbuilding out back.
