About a third of the city of Fort Wayne is served by combined sewers. Combined sewers collect sewage from homes, businesses and industries and carry it to the Water Pollution Control (sewage treatment) Plant for treatment. When it is not raining, all the sewage goes to to the plant and is treated. When it rains or when snow is melting, these combined sewers also collect and carry rain water runoff or melting snow. Sometimes the sewers cannot carry all of the combined wastewater flow so the sewer system allows some combined sewage to be discharged to the rivers. When sewers were being designed and built in the late 1800s and the first half of the 1900s these combined sewer overflows were an acceptable way to design sewer system. Following the implementation of the Clean Water Act in the 1970s, combined sewers could no longer be built and communities with combined sewers are now required to make significant investments to reduce these combined sewer overflow events.
