ABSTRACT In general, the invention consists of a chimney for sewers or the like provided with a pre-cast concrete, including a steel-reinforced bridge assembly which is adapted to straddle a main sewer line, the bridge having a bore to receive a vertical nipple extending upwardly from the main line. A pre-cast concrete, steel-reinforced transitional section is mounted over the bridge and has a central vertical bore overlying the bridge bore for connection at its upper end to an intermediate or Y-branch section. A fluid-tight flexible seal lies between the bridge bore and the nipple. More specifically, a transitional section is mounted between the bridge and a transitional Y-branch section and is formed with a vertical bore that joins the bores in the bridge and the cap block.
