A door is attached to the protective layer and situated over an aperture in the tank and in the concrete layer. A battery provides power to a fan disposed in fluid communication with one of the ventilation conduits. A solar cell is attached to the outer surface of the concrete layer and provides a charging signal to the battery. A fluid basin attached to a fluid drain conduit is also provided. The fluid drain conduit extends through the tank and concrete layer. In a second embodiment, a tank is surrounded by a horizontal rectangular frame.
