Little project, big help needed.

I have bought an old house/shack in Dominican Republic.
There is no water pumped into the house, the water is stored in an outside cistern and water is then bucketed into drums in the small bathroom for washing and flushing the toilet.
My aim is to have water pumping into a drum container I will mount above the bathroom, so that the shower, sink and toilet will be supplied by gravity.
First off, the constriction of the place to hold the drum conainer, I plan to build three sides inside the 4 walls of the bathroom and then put rebar across the top and concrete the top so that the drum will sit nicely on this. The construction itself will be built against the existing wall and kind of self standing, I just don't see the point in knocking down existing walls if I don't need to, they don't hold anything up and none of the interior walls go up to the ceiling. SO do you think this will be good enough to hold my water container/drum?
Then I need to find some kind of pump to pump the water from the outdoor cistern, to the drum I will mount inside or outside the kitchen, to supply the sink, and also to supply the bathroom drum I mentioned previously. So I could do with advise on that. The outdoor cistern is a big concrete 2mtr x 2 mtr structure with no holes, only a tap on the back to fill the buckets. Ideas please?

SO say I have the pump fitted, how will I get the pump to stop pumping once each drum is full, I need some sort of cut off thingy as they will fill at different rates and be used at different rates.

I think that will do for now, I'll take you further into my dilemma once I have been advised and taken in on how I can do this, on a budget.

Thankyou.

As long as you have power and water available at all times, the same pump that would put water in the gravity tanks could just be hooked up directly to the sinks, showers, and toilets.

If you only have water and/or power available some of the time, storing water is a good idea.

But to automatically fill multiple containers, I would use a float switch and a solenoid valve for each container. The pump works off a pressure tank and pressure switch. It will come on when a solenoid valve opens and go off when no water is being used.

Thankyou very much, very useful. The electric goes off typically between 10am and 6pm, and so I'd like to have the cistern pump water to the drums in the morning that would be enough for the day and then maybe again in the evening.
So the pump I would need will be just like a submerged pump I use in the caravan right? That just pumps when I switch the water on, but I could buy a timer and have it pump for a minute of 2 each morning? I am not sure how I would hook up a float switch to turn off the pump, it is technical, are there any links you could show me with diagram and 'how to' please.
Greatly appreciated.
