Looking for water pump

I have a 1500 gallon water cistern, approximately 8 feet tall. It will be located right next to the house on the same side as the kitchen and bathroom. I am looking to install a water pump and would prefer to use a DC pump since I'll be using solar on site anway and I'll have the battery storage room near the water cistern/pump also.
At the most there will be maybe a shower running and a load of clothes being washed and probaly rarely will this even be at the same time. I don't foresee any more water than that being needed at any given time. All outside irrigation will come from greywater recycling or from a separate water cistern.
I am looking for a DC battery powered pump that can provide sufficient water flow but still use as little power as possible.
