A method for maintaining soil moisture for a garden via a sump pump includes installing an irrigation sump pump in a sump pit; providing a water storage container; connecting a first conduit to the irrigation sump pump and the water storage container, the first conduit promotes water transfer from the sump pit to the water storage container; disposing at least one water distribution member at a predetermined area of a garden; connecting a second conduit to the water storage container and at least one water distribution member, the second conduit promotes water transfer from the water storage container to the one or more water distribution members; controlling the water level in the sump pit; controlling the water level in the water storage container from exceeding a predetermined high water level via an overflow pipe; installing at least one moisture measuring member or controller for determining a moisture content for at least one predetermined area of the garden; and distributing water upon a predetermined area of a garden when the moisture content is determined to be below a predetermined low moisture parameter, whereby water in the sump pit is distributed upon at least one predetermined area of the garden to increase soil moisture when the soil moisture level for the at least one predetermined area of the garden is determined to be below a predetermined low moisture parameter.
