The arched flush gate can be operated hydraulically, electrically or pneumatically. In each case, the body of the flush gate is lowered into the sewer using an actuator which keeps the gate closed until the required amount of flushing water is collected, at which point it abruptly opens to release the flushing water surge. The centrally placed hydraulic actuator ensures an even distribution of pressure on the seal.
