Had a brainstorm yesterday on an outhouse toilet to reduce the smell. Maybe good for schools and rural households. Works kind of like a boat/trailer toilet except the ball valve is replaced with a 4" PVC pipe. Ideally the seat would be specially made like this:
Seats like this are $13 from Cabela's hunting supply in the US
Materials needed:
2~ 5 gallon buckets
Toilet seat- bucket type if available
Concrete ~40 pounds
24" 4"-6" PVC Pipe
Handle
Form oil or grease
Bolts, screws
Construction:
Mark a 11"-12" section of the pipe into lengthwise quarters about 3" from one end of the pipe. Cut off opposite panels to make a cylindrical ball valve Fit a greased block of wood into the hole. Install handle/lever on one end. Pour concrete to fill the pipe. When set, remove the block. Clean outside of pipe of any concrete.
Make a concrete plug with the valve mechanism. Cut the bottom out of a 5 gallon bucket. Cut two round 4" holes at least 1 1/5" from the bottom edge. Put the PVC pipe with release oil or grease through the holes and replace the block(greased) so that it creates a vertical chute. Tape around openings to help with release and to prevent leaks. Fill to at least 1 1/2" above the PVC pipe. Remove blocks when partially set and make sure PVC will release.
Cut a 2" slot through the bottom of another five gallon bucket. Block the bucket on its side and pour about a gallon of concrete flush with the slot to make one half of the chute. Some screws in the sides will help prevent it from moving when it is set. Repeat to make the other side of the chute.
Set chute on top of the first bucket to line up the chute with the ball valve.
Set over a cess pit in an outhouse with a poured concrete or other form of airtight floor. When pouring the top, make a hole slightly smaller than the base of a five gallon bucket to set the device onto. A step flush with the bottom of the upper bucket will make it more comfortable to use.
When the toilet is in place, put the pipe through the bottom bucket and secure on either side to prevent lateral slippage. One option would be to make the handle weighted so the ball valve is kept closed unless operated.
When the lever is down it creates a vapor barrier between the cess pit and the outhouse. When lifted up it opens the chute and works like flushing a standard toilet. Odors can be futher reduced by using an Ammonia based disinfectant spray between uses. The cess pit must be vented to prevent gas build up.
You need to build a urinal for men since both seats do not flip up as in a standard toilet seat.
