1. A toilet having a bowl and a pressurized water supply with a channel for injecting water under pressure into a trapway, the trapway extending between a bowl opening and an outlet, the trapway having an up leg extending upward and rearward from the bowl opening to a water dam region above the bowl opening and a down leg sloping substantially straight downward and forward the entire length from the water dam region to the outlet at an angle between 40 and 60 degrees with respect to a horizontal plane containing the outlet, wherein the down leg of the trapway includes a baffle located adjacent to the horizontal plane containing the outlet for accumulating bulk waste upstream from the outlet and wherein during a flush cycle the toilet effects a siphon when a threshold concentration of bulk waste material is present within the trapway but does not effect a siphon when that concentration of bulk waste material has not yet been reached in the trapway.
