The update came out with the Evergreen Historic District news today. Both Chris Morton and Bill Bullock of Evergreen were planners for the sanitary sewer meeting.
"Last night several dozen midtowners met at Evergreen Presbyterian Church to learn about plans for resolving the causes of sanitary sewer backups in basements during heavy rain events. Public Works Director Dwan Gillion was on hand with his staff to address issues. Also on the agenda was a representative of the Tennessee Clean Water Coalition, and a presentation of the data collected so far from affected Midtowners.
If you have had issues and filled out a survey, that information will be shared with Public Works to help them pinpoint the trouble areas and design and implement solutions. Public Works indicated they have been performing "smoke surveys" to locate breeches in the sanitary and storm sewers. If you have yet to fill out a survey, fill it out and send it in soon- it will presented to Public Works in a few days. To download a copy of the survey, click here.
Director Gilliom and staff indicated that the solution will require an assessment of the specific problems which they are doing now, the hiring of a consulting engineering firm to design the solutions, and then the implementation of those solutions which may include realigning existing pipe, lining existing pipe with a "cured in place" product, or replacing pipe. There was an indication that such fixes may take as long as two years from now.
Most evidence points to these issues being caused by breaches in storm and sanitary sewers in city owned right-of-way. However, Director Gilliom noted that some issues may be exacerbated by issues with a homeowner's service line - the sewer line from the road right-of-way into the house. He recommended making sure all clean-out caps in yards are in place. He also advised than any repairs to that line are the homeowner's responsibility. A clean-out cap is usually a 5 inch diameter metal or PVC threaded covering over a sewer pipe in your front, back or side yard. If it is missing, storm water or other foreign material can enter your service line."
