Junction Chambers

The junction chamber provides access to the sewers and also allows the flow from the sewers entering the chamber to be combined without excessive turbulence and loss of head. Each junction chamber presents a special design problem necessitating a careful structural and hydraulic consideration. The principal objective in the design is to provide a safe and economical structure, which will combine the flow smoothly without decreasing the velocities appreciably and without causing backwater conditions in the sewers, which enter the chamber. A typical junction chamber is shown in Figure 11.
