Wherever feasible, every house-drain in the villages and rural districts of Hongkong and Kowloon shall hereafter be an open drain consisting of a semi-circular channel, of glazed stoneware jointed in cement mortar and laid to adequate falls on a bed of good lime or cement concrete, to the satisfaction of the Board.
56. In isolated places not connected with any public drainage system, every such open drain shall lead and empty into a covered sump or cesspit built of brick or lime concrete rendered smoothly in good Portland cement mortar in such manner as to be water tight.
