The table presents CSO overflows that may be expected in an average year based on a predictive computer model of the sewer system developed by WASA. The predictions are for the system with the inflatable dams operating, prior to rehabilitation of the pumping stations. The pumping stations are being rehabilitated, and this will further reduce the overflows.
