This primary batch of sludge contains nearly 50% of suspended solids within wastewater.

The assessments identify water quality problems within the states and jurisdictions, list the impaired and threatened water bodies, and identify non-point sources that contribute to poor water quality. Every two years states must submit reports that describe water quality conditions to EPA with a complete inquiry of social and economic costs and benefits of achieving goals of the Act.

How does disinfection help with waterborne diseases?
Disinfection of wastewater and chlorination of drinking water supplies has reduced the oc-currence of waterborne diseases such as typ hoid fever , cholera, and dysentery, which remain problems in underdeveloped countries while they have been virtually eliminated in the U.S.Infectious micro-organisms, or pathogens, may be carried into surface and groundwater by sewage from cities and institutions, by certain kinds of industrial wastes, such as tanning and meat packing plants, and by the contamination of storm runoff with animal wastes from pets, livestock and wild animals, such as geese or deer. Humans may come in contact with these pathogens either by drinking contaminated water or through swimming, fishing, or other contact activities. Modern disinfection techniques have greatly reduced the danger of water-borne disease.
How does wastewater flow?
As wastewater enters a treatment facility, it typically flows through a step called preliminary treatment. A screen removes large floating objects, such as rags, cans, bottles and sticks that may clog pumps, small pipes, and down stream processes. The screens vary from coarse to fine and are constructed with parallel steel or iron bars with openings of about half an inch, while others may be made from mesh screens with much smaller openings. Screens are generally placed in a chamber or channel and inclined towards the flow of the wastewater. The inclined screen allows debris to be caught on the upstream surface of the screen, and allows access for manual or mechanical cleaning. Some plants use devices known as comminutors or barminutors which combine the functions of a screen and a grinder. These devices catch and then cut or shred the heavy solid and floating material. In the process, the pulverized matter remains in the wastewater flow to be removed later in a primary settling tank.

The federal govt also provides funding for state plants under the CWA.
Why do sewers release?
Releases or bypasses can be caused by accidents, such as pumps failing or pipes bursting. Sometimes wastewater operators may be forced to release or bypass if they have to shut down equipment for emergencyrepairs and there's no feasible way to reroute or contain the wastewater. Heavy rains, rapid snow melt, or flooding can also cause a release or bypass when more water gets into the sewer system than it has the capacity to move (system overload)

CWA carried over term "navigable" waters, but broadened it - navigable waters = waters of the U.S. for CWA. Why? because goal of CWA = to restore the chemical, physical and biological integrity of the Nation's waters, can't do it if CWA ignores adjacent wetlands, tributaries and other waters with significant nexus to navigable waters.
