The liquid waste
http://www.crd.bc.ca/es/lwmp/images/clover.jpgcomes from the toilet behind me. There’s a containment vessel for the solids. From the bottom of the solids you drain off the liquid and it comes down here down this pipe. OK. The pipe tips into this tipping bucket arrangement, and what this does is it fills up to a point, and then it suddenly tips and that will measure each time it tips. So we can calculate the amount of liquid effluent that’s gone in. As that fills up, you can see the towelling material here will come in contact with the effluent, the air is drawn in through these holes and will actually direct the air in onto the surface of the water, through the wick and out through the top.
