ABSTRACT:
For a pneumatically driven drainage facility, an intermediate station for receiving and boosting the liquid and air through the system. This intermediate station comprises a tank with an inlet for receiving the air driven liquid such that the liquid collects at the bottom of the tank. A first branch line communicating with the tank above the surface of the collected liquid extends outwardly from the tank for the passage therethrough of air which has entered the tank. A second branch line leads from the tank for delivering the collected liquid, a pump being provided for passing the liquid from the tank into the second branch line. The two branch lines join again at a point downstream from the tank in a descending conduit section, the first branch line entering the descending conduit section downstream from the entry therein of the second branch line. The descending conduit section ends with a U-shaped adjoining pocket.
