An apparatus and system are disclosed for retrofitting a septic tank from a failed residential wastewater treatment system to permit discharge to a surface water body rather than an underground drainage field. The apparatus is a chlorinating tank, comprised of a tank having an inlet and outlet pipe. An inlet diffuser and an outlet diffuser are posited within the chlorinating tank, the inlet diffuser is in hydraulic communication with the inlet pipe, and the outlet diffuser is in hydraulic communication with the outlet pipe. A filter is posited in the outlet diffuser for filtering any remaining solids in the treated wastewater. A chlorinating device is posited downstream of the filter within the chlorinating tank, for adding dissolved chlorine to the chlorinating tank volume.The system for treating domestic wastewater utilizing a failed septic system is comprised of a source of pressurized air, a sparger for sparging the pressurized air into the waste water contents of the septic tank, a chlorinating tank, comprised of means for mixing the partially treated wastewater, a filter and a chlorinating device, and a vent line for routing and treating noxious vent gases from the septic tan…
