tt post sep 27, 2017 sewer overflows

This comment focuses on  urban sewage overflows, everyone's favorite subject, that occur mainly around heavy rainfalls.

Again, view "Toledo Aerial Media's":http://www.toledoaerialmedia.com/ 360-degree view of the downtown bloom found at this link.

Does the algae bloom exist in the Maumee River upstream of where Swan Creek enters?


bq. _"Maybe all the Swan Creek sewage. I know there is an outflow right at Promenade Park."_


I recorded 0.32 inches of rainfall on Mon, Sep 18, and 1.40 inches of rainfall on Tue, Sep 19. 

Most of Tuesday's rain fell during about a 90-minute period, mid-morning. It poured hard at times. I encountered some minor street flooding. 

Tuesday's rainfall was not localized. It occurred over a decent-sized area, I think. Toledo Express Airport "recorded":https://www.wunderground.com/history/airport/KTOL/2017/9/19/DailyHistory.html 1.65 inches of rainfall on Tue, Sep 19.


The combined sewer overflow (CSO) data for Sep 18 and 19, 2017 can be found at this website. I've listed the data below.

From the above website:

q.
Combined sewer overflows (CSOs) occur when storm water mixed with sewage overflows into the Maumee River, Ottawa River and Swan Creek. 

This section includes a map showing the location of the CSO outfalls and monthly charts going back to July 2004 listing the dates of CSO overflows, their location and their duration.

It seems odd that some high numbers were recorded for Sep 18 when it didn't rain much, and it didn't rain on Sep 17. Maybe the Sep 18 rainfall was more localized with heavy rain occurring over scattered areas around Toledo. We would need radar data for Sep 18-19.

Since June 1, the biggest sewer overflows seem to have occurred across Jun 22-23, but the Sep 18-19 period might be among the worst periods, since June 1.


The CSO location numbers can be found on maps at the above website.

Outflows 68, 43, 26, 7, and 6 are located along or near the Maumee River in downtown.

The outflow labeled "CSO #6 Main" had some issues both days last week, and it's located, I think, on the east side of the Maumee River, near the MLK bridge.

And if I understand the data below correctly, "CSO #6 Main" dumped a slurry of sewage and storm water into the Maumee River for a combined 9.3 hours across Sep 18-19, 2017.

br. If the city wants to take legal action against the biggest offenders that have contributed to the algae blooms, then the city might need to look at itself.

q.
Councilman Lindsay Webb, chairman of council’s public utilities committee, said *urban sewage overflows* need to be controlled better.

*“The city cannot point fingers at the farming community unless we clean up our side of the street.”*
q..

That's a  sensible statement from a local politician.
