I need advice on setting up a system to pump water from a lake. We are off grid and have a generator but do not want it to run all day.
At our last cottage we used a gas water pump to get lake water from the lake to a barrel up a hill. It then ran to the cottage, a 12 volt pump, ecotemp L10 and to our sink.
This worked well but since I am starting with nothing I am wondering if there is a 12 volt submersible pump that I could use with a pressure tank and small Solar panel, battery and charger controller to eliminate the holding tank. I don't like the idea of lake water sitting stagnant for weeks at a time in really warm weather.
This is for 3 season use. I am guessing it would be a 50-75' distance (Lake to sink, bathroom) and maybe 20-30' rise over that distance. I am a bad judge of distance though so this may be off.
I could always just empty the tank when we leave but thought I would check to see what others have done.

I don't see why you couldn't just put an intake line into the lake, use a 12V pump (with battery, solar panel etc.) in a box right at the lakeshore. Many pumps will suck water up from a few feet. Of course I would house the pump in something weather-resistant or weatherproof unless it is designed to be outside.

Some of the 12v RV pumps are self priming for a few feet of lift and cost less than $ 100. sounds like an option to research. See the attached blog on RV pumps. Sounds like a simple, not very expensive way to set it at the lake edge and pump and why install a tank, just do "on demand".

Thanks for you replies.
I have a flojet pump that I bought with an Eco temp hot water heater. I will have to try out the pump at the edge of the lake. I am not sure if it will be strong enough to give us enough pressure for the water heater and sinks at the cottage

If you have good rainfall, you could catch the water from your roof and then its simple to pump into the cabin. No need to lift it from the lake.

Thanks Ontario Lakeside I had not thought of that. I am sure that would keep the tank full considering our low needs.

Or you could pump to a holding tank barrel above.by the cottage. Use the flow
Jet from there.
