The projects we're talking about today help deal with improvements to clean water, but also help deal with some major issues that weve had with respect to combined sewers
, with respect to upgrades and studies on our infrastructure and our plants.
Located near Crompton Park, the Quinsigamond Avenue Combined Sewer
Overflow Treatment Facility functions as a sewer pumping station during dry periods or small rain storms, when only sewage or sewage mixed with moderate amounts of runoff is flowing through the combined sewers
According to a consent decree filed in September in federal court, the city is required to develop and implement a comprehensive plan to reduce, and where feasible, eliminate overflows into the Ohio River from its combined sewers
by calendar year 2020 or 2025, depending on Jeffersonville's financial health; implement a plan with specific actions to improve the capacity, management, operation, and maintenance of its sanitary sewer system to eliminate overflows of untreated sewage; and eliminate all discharge points within its sanitary sewer system.
The wastewater treatment industry argues that bypassing biological treatment for a portion of the water is a significant improvement over releasing completely untreated wastewater, which is what happens when combined sewers
Tires, logs, and other river debris caused sewer plugging, especially at the regulator transition from combined sewers
to the intercepting sewer.
Recent modifications to the Consent Decree, established in 2006 to address the problem of raw sewage flowing into streams and waterways through combined sewers
across Indianapolis and finalized in December 2010, will allow the City to move forward on the project years ahead of schedule.

In some locations, such as Cumberland and Washington, DC, the mud and sludge drains into combined sewers
(that hold both rainwater and raw sewage) and, if it rains (in some areas more than 1/10 of 1 inches), overwhelms the combined sewers
and flows directly into the Potomac River and its tributaries without first being treated.
A major source of this is the trash and debris discharged from combined sewers
and storm sewers during rain events.
The City has reported a large number of basement flooding incidents over the years in the combined sewer
area resulting from surcharging of the City's combined sewers
, which carry wastewater and stormwater in the same pipes.

The combined sewers
flow to the riverfront where they connect with the river-front interceptor, which carries the waste-water to the treatment facility.
