Tonight we are discussing WWTP (Agenda item 4) and system hydraulic modeling scenarios (agenda item 5).

Among these discussions, I would like to hear about a wet weather SSO event that occurred at manholes outside the target areas (I mentioned this event at the last meeting). I am interested in relating this to the modeling work that Murat has done (and the data evaluation Robert presented) to understand how modeling and data describe the sanitary capacity in this area. I am also interested in hearing about the results of any city investigation of the sanitary leads related to this event.

The event occurred on May 25, 2011 and is described in a report to DEQ as follows:

"Heavy rain, plus inflow from area footing drains connected to sanitary sewer, overwhelmed sewer system and resulted in sewage overflow from manholes located near Hill/Division St. and Hoover/Division St. intersections."

Also, I have attached a spreadsheet with all the reported overflows from the DEQ site back about 5 years (plus some older ones that were interesting).
