This paper presents the findings on the operation of demonstration set up comprising 4 small pigsties, accommodating a total of 200 pigs, with associated dung channels and soakaway system. The set up is built for the purpose of demonstrating the technical feasibility of the dry muck out method in handling small volume of pig waste. The whole cleaning operation which involved the actual muck-out of waste solids from the pens and hosing out the residual waste, and clearing any solids at dung channels and soakaway pits took about 4 man-hours per day. With the use of special biting type water drinkers and water spray gun, the water consumption was restricted to an average of 14 litres per pig per day. The soakaway facilities have been functioning well in disposal of liquid waste generated from the 4 pigsties. The operational result covering a 12 month period has led to the conclusion that the dry muck-out method demonstrated is a feasible and effective waste management method for handling pig waste in small farms
