A waste water disposal system, in particular a sewer system, including a plurality of collecting containers (3) each divided into a lower space (8) and an upper space (7) separated by a partition (9) including a valve member (10) therein. Sewer connections (1) are connected to the upper spaces (7) of the plurality of collecting containers (3) via supply pipes (2). A discharge pipe (5) is connected to the lower spaces (8) of the collecting containers (3), and a pressure pipe (13) including a compressed air source (16) is connected to the lower spaces (8) of the collecting containers (3). A control system (12) provides for the selective emptying of the collecting containers (3) into the discharge pipe (5) by introducing compressed air into the collecting containers (3) via the pressure pipe (13). The pressure pipe (13) and the discharge pipe (5) are separate pipes, and the collecting containers (3) are interconnected in parallel between the pressure pipe (13) and the discharge pipe (5) to which they are connected via connecting pipes (4,14). The connecting pipe (4) of the discharge pipe (5) of each collecting container (3) runs upwardly from a level near the bottom of the collecting container (3) and is connected to the discharge pipe (5) at a higher level. The compressed air source (16) is connected to provide compressed air simultaneously to all connecting pipes (14) to force waste water through the connecting pipes (4) and the discharge pipe (5).
A waste water disposal system comprising a plurality of collecting containers (3) each divided into a lower space (8) and an upper space (7), said lower and upper spaces (8, 7) are separated by a partition (9) comprising a valve member (10) therein, waste water connections (1) connected to the upper spaces (7) of the plurality of collecting containers (3) via supply pipes (2), a discharge pipe (5) connected to the lower spaces (8) of said collecting containers (3) via connecting pipes (4), a pressure pipe (13), a compressed air source (16) connected to said collecting containers (3) via connecting pipes (14), and a control system (12) for selectively emptying said collecting containers (3) into the discharge pipe (5) by introducing compressed air into the lower spaces (8) of the collecting containers (3) via said pressure pipe (13), wherein the pressure pipe (13) and the discharge pipe (5) are separate pipes, the collecting containers (3) are interconnected in parallel between the pressure pipe (13) and the discharge pipe (5) via the connecting pipes (4, 14), the connecting pipe (4) of the discharge pipe (5) of each collecting container (3) runs upwardly from a level near the bottom of said collecting container (3) and is connected to discharge pipe (5) at a higher level, and the compressed air source (16) is connected to provide compressed air simultaneously to all connecting pipes (14) to force the waste water through the connecting pipes (4) and through the discharge pipe (5).
