The drainage system behind each wing wall can be
connected to the drainage system behind the
abutment using 2 - 90^ bends and a short length
of pipe. This will necessitate the
drainage system behind the wing wall
be slightly higher.
For wing walls over 15 ft. long, the
drainage system behind them may be
independent of the drainage system
behind the abutment. They can be
outletted directly through the wing
wall.
