In some locations, such as Cumberland and Washington, DC, the mud and sludge drains into combined sewers

and flows directly into the Potomac River and its tributaries without first being treated.

In turn, the combined sewers
could then be used to store and carry excess sewage that is frequently discharged from SSO 700 when it rains, thus eliminating these SSO 700 overflows.
