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 ? 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.

A reconfigurable and scalable fluid distribution system including a compression unit, a storage unit, and a control unit. The compression unit, storage unit and the control unit are in fluid, electronic and electrical communication with one another and are coupled together in a stacked relationship, each in abutting relation to the next. Additional compression, storage and/or control units may be coupled in abutting relationship to an existing stack of coupled units. A method of assembling a reconfigurable and scalable fluid distribution system. A method of dispensing fluid via a reconfigurable and scalable fluid distribution system. A control unit for use in a reconfigurable and scalable fluid distribution system.
