Hi Everyone thanks is in advance for your help. I am looking for help to design a simple water system but with high lift.
My cabin sits about 140ft above the lake on rock. I want to draw water from the lake to feed a kitchen sink and bathroom sink. Maybe an outdoor shower in the future. Toilet is going to be a propane compost no need for water
Power system is 11kwh solar system.
I was thinking of using a 1hp 110v Hallmark submersible pump. I don't think I can pump it to a pressure tank. As well eventually want to add a small automatic propane water heater for washing dishes.
What would be the best way to do this.
Thanks

You could use a submersible solar well pump (if you have the sunlight down at the lake to recharge it) and pump up to a storage tank at the cabin. Then you could use a Sureflow pump at the cabin to pressurize the water for use there.
Not sure this is the best way. Others will have some better ideas, I'm sure. You mentioned an 11 kwh solar system. Not quite sure what you meant, but if its actually 11 kw of panels, lots of storage, and a big inverter, I doubt you'd have any trouble running a pump at the lake that could pressurize the place. (But I don't think you meant that).
I do have a question for you about the toilet you mentioned. You mentioned propane compost. Are you looking at some kind of hybrid that uses propane to get rid of the liquids and compost for the solids? If so, post a link...sounds interesting. Or did you mean either propane or compost?

Thanks for the reply.
The solar system ia11kwh and I do have lots of power. This pump seems to the biggest 110v I can find. I am going to run power down to the pump. the specs state the max lift to 20/40 psi pressure tank is 110ft. That's why I need a different way to get it up. Maybe to a holding tank or something else.
The toilet we have ordered is Cinderella incinerating toilet uses propane and a little hydro. They have an additional toilet for liquids that goes with the system to separate it.

What is the distance from house to lake?

You might want to look at a deep well jet pump, some of them can pull water up 200'. There are advantages to having the pump close to the power source; a 110V 1HP pump pulls about 14A and a lot more on startup, the losses in 140' of wire will may be significant.
As for incinerating toilets, I know somebody who had an electric one... my understanding is that it stunk, used a lot of power, and sounded like a jet airliner taking off. We chose a composting toilet instead.

Ha ha. Back in the early 80's we had friends that had a propane toilet. The brand name was "Destroilet". They loved it. It scared me. Always wondered what would happen if the "destroy" cycle happened when my nads were hanging in it.

The height is about 150ft and probably a total run of 275ft.
This toilet apparently has small electrical draw and no smell. I hope.lol

$5,190???  And I thought our composting toilet was expensive...

You need the total head from lake level to point of use. Total run really dosnt matter. Also an about measurement dosnt work well for a total head number. Looks can be very deceiving with you try to eyeball elevation.

Oh boy! I like running transit, builder's and grade levels, fun stuff Got the toys, like to play with 'em.
If you were close......
There are some simple, ages old methods (look online) and you can do it pretty easy with some tools may be already have. A little time, an assistant, an inexpensive laser level and a broom handle with a yardstick taped to it could do it.

If you have a relatively low planned water consumption, you might check out rain water harvesting from your roof, even though you are close to the lake. It’s generally cleaner than surface water. I set up a 300 gal tank, and feed it from about 180 sq ft of roof, and has kept the tank full even in a pretty arid area. Every 100 sq ft yields about 62 gallons with 1†rain. Simple cistern pump, filter, and uv sanitizer, feeds a sink and shower.

If all you're feeding is the kitchen and bathroom sink, how much *extra* head could you get from a tank higher up on your property?
If you can get 30' above your cabin for a reservoir, you could pump up when you can (solar/whatever) and then use gravity to get 15psi+ for your fixtures whenever you want to turn them on, without needing pressure tanks.

That would work fine. Even a 4ft level on a tripod and some time.

Doesn’t matter much for hydraulics unless you are trying to use like 1/2†pipe but total wire length is something to be concerned with if you are using a submersible pump.
