Opinion

ORDER

JOHN R. ADAMS, District Judge.

This matter appears before the Court on the Government’s unopposed motion for entry of the proposed consent decree (“the Decree”). The motion is DENIED.

I. Combined Sewers Explained

Generally, there are two types of water collection systems: combined sewer systems and separate sanitary sewer systems. For decades, separate sanitary sewer systems have been the exclusive systems constructed in the United States. As a result, combined sewers are “artifacts of an earlier way of collecting sewage and storm water.” Doc. 68-1 at 3. Mark Klingenstein, a licensed professional engineer, described the two types of sewer systems as follows:

In combined sewer systems, one set of pipes is used to collect and transport both wastewater and storm water. During dry weather, only wastewater flows through the pipes; this wastewater flows to the treatment plant to be treated prior to release to the river or ocean. During wet weather, storm water also flows into these same pipes. During very small storms, all of the storm water will also flow to the treatment plant for processing; however, during larger storms too much storm water will be collected for the treatment plant to handle. Under these circumstances, overflows to the river, lake or ocean take place from structures designed and constructed to discharge combined sewage under these higher flow conditions. These structures are known as Combined Sewer Overflows (“CSOs”) and are typically located throughout the combined system. The discharges from these structures consist of a mixture of untreated sanitary sewage and industrial wastewater, groundwater infiltration and storm water.
In separate sewer systems, sanitary sewage is collected in one set of pipes, and storm water is collected in another. By design, only sanitary sewage should be conveyed to the wastewater treatment plant, regardless of the weather.

Doc. 68-1 at 3-4. Combined sewer systems contain a wide range of human pathogens including bacteria, viruses, and parasites. “When CSOs result in the discharge of raw sewage into surface waters which are used for contact recreation or as drinking water sources, they represent a significant pathway for the possible spread of numerous diseases.” Doc. 68-1 at 4. This fact is particularly poignant when the Court takes into account that Akron’s annual discharges of untreated or partially treated sewage exceed two billion gallons per year. 1 Moreover, the risks accompanying these pathogens are exacerbated by the relatively small size of the waterways receiving the discharges:

The Cuyahoga at less than 500 [cubic feet per second] as a mean flow, is not a very large river. It doesn’t provide very much assimilative capacity. There isn’t very much river to disperse and dilute CSO discharge into.

Doc. 87 at 34.

In the case of the Ohio Canal, given its characteristics, it’s sort of like a bathtub with an opening at the end. And when you discharge the CSOs into it, it will increase its flow and then it will come back to sort of its steady state.
*784 But a lot of what will be left in it at that point will be residual [raw sewage] from the discharge.

Doc. 87 at 36-37.

II. The Akron Sewer System

In the late 1800s, Akron began construction of its sewer system. Initially, Akron utilized combined sewers. From 1910 to 1920, Akron’s sewer system was substantially expanded using combined sewers. In 1923, Akron adopted a separate sewer system policy. Accordingly, all construction following 1923 has involved separate systems for storm sewers and sanitary sewers. Despite this change going into effect nearly 90 years ago, Akron still maintains numerous combined sewers— those sewers currently comprise nearly 30 percent of the Akron system. These combined sewers are at the heart of this litigation.

Overall, Akron’s system serves roughly 328,000 people in a service area spanning 183 square miles. The system includes the cities of Akron, Cuyahoga Falls, Hudson, Fairlawn, Stow, Tallmadge, Lakemore, Mogadore, Munroe Falls, and Silver Lake. The system also includes the Townships of Bath, Coventry, Copley, and Springfield. The full system contains approximately 1,365 miles of sewer pipe. There are 175 miles of combined sewer pipes, 690 miles of separate sanitary sewer pipes, and 369 miles of separate storm sewer pipes. These sewers, along with 39 pump stations, transport the collected wastewater and storm water to Akron’s wastewater treatment plant.

The wastewater treatment plant is an activated sludge treatment plant. Klingenstein described the processes of the plant as follows:

i)Wastewater entering the plant first passes through screens that remove rags and debris from the wastewater. The collected material is hauled offsite for disposal in a landfill----
ii) Degritted wastewater then passes through two channels to several preaeration tanks, in which air is added to raise the dissolved oxygen level in the raw sewage. One of the two aforementioned channels is equipped with a gate through which raw wastewater can be diverted to a 10 MG capacity storm retention facility....
iii) From the pre-aeration tanks, the aerated wastewater flows to 24 rectangular primary clarifiers. In these tanks, settleable solids are removed via simple gravity settling....
iv) Following primary clarification, the wastewater flows to the single-stage activated sludge system----Air is added to the aeration tanks as well, creating conditions in which the organisms can first adsorb and then metabolize soluble pollutants in the wastewater....
v) ... Following secondary treatment, the treated wastewater flows to two parallel chlorine contact basins for disinfection and dechlorination (to remove residual disinfectant) prior to discharge to the Cuyahoga River. Waste sludges are thickened and composted prior to disposal by land application.

Doc. 68-1 at 6-7. The plant is also equipped with several bypass capabilities. Through the bypasses, wastewater can be bypassed directly to discharge prior to preliminary treatment, directly to disinfection from the stormwater retention facility, and from a point just prior to secondary treatment.

Within the combined portion of the sewer system, there are 37 diversion structures known as “racks” and at least 35 active CSO points. Six CSOs discharge into the Cuyahoga River, twenty-one discharge into the Little Cuyahoga River, seven discharge into the Ohio Canal, and one discharges into Camp Brook. Ultimately, all of these discharges, whether *785 directly or through tributaries, flow into the Cuyahoga River and the Cuyahoga Valley National Park.

In turn, the Cuyahoga River then flows into Lake Erie, the thirteenth largest lake in the world. While the fourth largest of the Great Lakes, Lake Erie’s fish population is the largest among the five lakes and supports commercial, recreational, and sport fishing.
