rain goes into the waste treatment center through the storm sewers. It is treated just like household sewer water. That is a requirement from the EPA.
This has been a serious problem for older water and sewer systems through out the country, particularly in the East and Great Lakes States. Large water events have caused the overflow of sewers directly into the lakes or oceans. This happens less than a handful of times a year and the water is clear within days. Yet because of this we have to spend billions to comply with new regulations.
Your EPA at work.
“rain goes into the waste treatment center through the storm sewers. It is treated just like household sewer water. That is a requirement from the EPA.”
No, it does not. It’s been a requirement to separate storm water for sewage. When storm water does get into waste streams, you end up having big overflows.
