Off grid stand alone water pumping for cottage

[Fishov]

Hello all,

I am new to this forum so please bear with me... I am looking for advice on creating a stand alone water pumping system for our cottage on lake of the woods in Northwest Ontario. I am planning on building up a larger solar power system next year to service the entire cabin but for this year I would like to get the water going.

I was hoping that I can pump from the lake to a 60-80 gallon pressure tank via 12v pump run off a panel and battery. Distance from the cabin to waters edge is approx 100 feet with maybe 15 -20 lift.

I would like to feed the kitchen sink, bath sink and one pint toilet, a couple of hose bibs and maybe an outdoor shower. I'd like to keep it simple for now but effective.

Does anyone have a similar system that works? Recommendations? Designs?

Thanks!

Better off to use a slow solar pump and fill a cistern that gravity feeds the house.

Trying to use solar to pressurize the system eats power faster than a class or wild 5 year olds eats candy in an ungruaded candy store.

Greetings !

Well, you have a couple stages to go through here.

Lift - 20' from pond. That's about at the limit for a suction pump. You may be happier with a submerged pump

total lift needed:
20' from pond
60 psi = 140'

[ p = 0.434 h
where
p = pressure (psi)
h = head (ft) ]

So to build up 60 psi in your pressure tank, you need about 160' of lift. A 12V pump can do this at a very slow rate, maybe 1/2 gal per minute. If you don't use a lot of water, you could manage with it.


What I did ( I needed a lot more water ) I used a small, 1/2 hp standard well pump, in a Flow Induction Sleeve, to pump uphill to elevated storage,(5, 3,000 gal tanks) which is where I get my water pressure 24/7. Power consumed is about 1,000 for 8gpm @ 160' lift.

do you have experience with this type of system...is it suitable for my region? can you provide enough pressure to trigger an demand LP water heater?

demand water heaters work off sensing flow rate, not pressure.

Don't know what it will take to rund the water heater.

I'm in the process of putting my system together. We will pump out of the well into a cistern. From there either gravity feed to everything or run a second pump to pressurize just a few things.
