A method according to the present invention for treating excess wastewater from a sewer system includes receiving excess wastewater from the sewer system in a first portion of a shaft structure; allowing a first quantity of the wastewater to flow from the first portion of the shaft structure into a tunnel in inhibitable fluid communication with the shaft structure; allowing a second quantity of the wastewater to flow from the first portion of the shaft structure into a second portion of the shaft structure when flow into the tunnel is inhibited; injecting a treating agent into the second quantity of wastewater so as to treat the second quantity of wastewater; and allowing a portion of the second quantity of wastewater to flow from the second portion of the shaft structure to an effluent passage in fluid communication with the second portion of the shaft structure after the step of injecting a treating agent.
