VACUUM OPERATED SEWERAGE SYSTEM Abstract A vacuum-operated sewer system includes an integrated main valve and controller upstream of a collection unit for admitting sewage into the system. An in-line valve unit has a piston-cylinder operator. A vacuum-operated controller and a pilot valve unit are mounted on the operator. A pressure sensor is connected to the gravity side of the valve. A surge tank and check valve connect the vacuum side to a supply port of the controller. A water trap tank is located between the bottom end of an intake air line and the connection to the valve operator and controller assembly. A mesh fills the tank to increase the heat transfer of the moisture laden air such that the moisture condenses out in the tank. A drain system is connected to the trap tank and the operator to discharge accumulated water from the control system into the sewer system during each cycle of the valve unit.
