Abstract
A trench is dug under an above ground water storage tank either before erection of the walls or after the wall is erected. A (rectangular) sump is preferably made of ¼ inch steel. It serves as a conduit from an inner tank liner port to an outside tank fill or drain port. The system eliminates hoses hung over the top edge of the tank wall. A pump can fill the tank from the outer port. The tank can be drained using head pressure of the water and/or a pump.
