description	PROBLEM TO BE SOLVED: To solve a problem in a dividing manhole of a conventional combined sewerage wherein inflow floating impurities flow out to a public water area when the water level exceeds the height of a division weir in rainy weather, which is one of causes of water pollution in the public water area. SOLUTION: This water surface control device for a drainage device has an inflow pipe, a discharge pipe, an intercepting pipe, and the division weir arranged to shut off the intercepting pipe and inflow pipe from the discharge pipe. A guide wall interposed between the inflow pipe and the division weir is provided, and the lower end of the guide wall is located below the top end of the division weir, while the upper end is located above the top end of the division weir. The upper end of the guide wall can be located above the top of the intercepting pipe. COPYRIGHT: (C)2006,JPO&NCIPI
