Abstract

The portable steel-reinforced HDPE pump station includes a vertically upright, cylindrical wet well fabricated from high-density polyethylene reinforced by helically wound steel ribs. HDPE profile wall material and endoskeleton are used for wet well reinforcement. Exterior foam insulation or thin HDPE shell wrap are disposed on outer portion of the wet well. The base of the pump station includes cross ribs atop a planar anti-flotation collar. Interior spaces between the cross ribs are filled with concrete to anchor the wet well in situ. Alternatively, a steel plate is used as a base. The steel plate base may be encapsulated by an HDPE sheet. HDPE sheets form a sloping hopper bottom at lower inside portion of the wet well. The annular space between the hopper bottom and base plate is filled solid with a closed-cell polyurethane insulation. Alternatively the wet wall is constructed of structurally reinforced thermoplastic without steel reinforcement ribs.
