The present invention is directed to a precast headwall unit for discharging water from a pipe to a waterway. The precast headwall unit has two back walls that serve to increase the integrity of the precast headwall unit and pipe coupling and 5 avoid the need for additional formwork during installation. The invention also covers retrofitting headwalls and culverts with a second back wall. Figure 1 1<7(3
