Common sense says that pipes that have been buried for a century and a half tend to leak. Over time, they also get clogged with debris or even congealed cooking oil, resulting in narrowed pipes that overflow even more easily.
When narrowed pipes are already overloaded, the added influx of stormwater when it rains becomes just too much water. Now, some cities experience overflows with less than a quarter-inch of rain, with resulting risks to human health. It is common for cities with combined-sewer systems to advise citizens to stay out of the water for days after any rainfall.
What is being done? Combined sewers have been an EPA priority for many years and, after decades of significant effort, the numbers are starting to move in the right direction, but this is not a problem that can be turned around quickly or cheaply. A single storm triggered a release into Lake Erie from Detroit, Michigan, of more than 44 million gallons of raw sewage from sanitary sewers and almost 3 billion gallons from combined sewers , and such releases from Detroit and the other cities with sewer outfalls on Lake Erie contribute to the fact that it blooms with algae every summer.
On the individual level, people concerned about wastewater can give some thought to the fertilizer, pesticides, trash, and animal waste that wash off of lawns and into sewer systems, lakes, rivers, and oceans. As citizens, they can also advocate at local, state, and federal levels for improvements. People can reduce stormwater flow by planting their own rain gardens and green roofs—and by being judicious about the way they water our lawns and wash their cars. Sometimes, doing the right thing is as simple as being careful about what goes into storm drains and toilets.
If Americans want to be able to drink tap water or swim at beaches after it rains, they have to keep trying to improve wastewater infrastructure, even if the size of the problem boggles the mind.

Is There Sewage Pollution in the Bay? What Can I Do to Help?
In Your Home Minimize water use e. Dispose of household chemicals and automotive fluids properly—not down household drains or curbside storm drains. On Your Property Inspect your sewer cleanout. The cleanout typically is a small pipe, about 4 inches in diameter, used to access the lateral line for cleaning.
Make sure the cap to the cleanout pipe is on and has not been damaged, and replace it if necessary to prevent rain water from entering the sewer system. Have your household sewer line inspected and replaced if necessary or urge your landlord to do so.
A lateral line connects the pipes in your house to the main city sewer pipes.
