the return wall 120 has a height of 1 5 inches applicant prefers that the barrier width h be at least one fifth the width of the bucket fig3 indicates another barrier 170 that could be used instead of the barrier 90 the barrier 170 can extend along the entire longitudinal m length of the first side portion 91 of the bucket at a height above more than half the bucket height g there is possibly a slot where water at 160 would hit the barrier an opening 172 allows for the outflow of water in the dump position thus the invention provides a dump bucket toilet that avoids large splashing of water when the bucket is tipped to its dump position which avoids scooping up water by the dump bucket returning away from the dump position so the tank can have a lower height and which assures that the bucket will return to the fill position after each cycle and with minimum noise a barrier lying above most of a first side portion of the upright fill position bucket prevents the sudden dumping of a large portion of water in the bucket when the bucket tilts to the dump position and consequent splashing instead water lying along most of the length of the bucket flows down to the bottom of the barrier to more slowly flow into the tank an opening for the water can lie between the top of the bucket first side and the barrier and or in one of them the bucket forms a hold down container that traps a considerable portion of the original water so it cannot rapidly flow out through a first end portion of the bucket that is kept open to receive water through the refill valve an axillary container provides.
