Abstract
To facilitate cleanout of a sewer a guide member is located with a manhole to guide a cleanout tool into the sewer. The sewer is downwardly inclined adjacent the manhole so that the inlet enters at a location below the outlet and a predetermined level of liquid is maintained in the manhole. The guide member comprises a base with a pair of upstanding wings that project above the predetermined level to present a pair of guide members for the insertion of the cleanout tool.
