with a bench...
...or with a
toilet bowl
Cut the bottom and side from a
plastic jug. Attach a tube to the
spout to divert urine. Put a fine
mesh screen in the jug to keep feces
and other things from falling in.
Cover the base with a
level platform of wood
or concrete with a hole
over each chamber.
Urine diverting toilet bowls can be built or
bought in some places. If they are available,
they are very easy to install and use.
