Complaint Description and Writeup
Complaint Description and Writeup
Mr Matthew Rice, Erwin Utilities (EU) reported a 4-11-16 overflow at the corner of Union/Carolina, Erwin via a 4-12-16 e-mail. The e-mail stated, "EU experienced an SSO (sanitary sewer overflow) of approximately 200 gallons from a manhole at the corner of Union and Carolina yesterday from 3:45 to 4:00 PM. The SSO resulted from a blockage. The flusher was used to clear the line." A report received on 5-13-16 indicated the following, "Both overflows were the result of a line failure that occurred due to the sewer main becoming over pressurized during the inversion process while performing cured in place pipe rehabilitation. The over pressurization caused severe damage to the clay pipe and the pipe bursting rehabilitation method had to be used instead. The 10" clay pipe (GM1137) located on Union Street between Carolina and Willow has been completed replaced with 12" HDPE. In addition, all sewer laterals have been replaced to the right of way. This problem has been completely resolved and no further issues are expected on Union Street. The areas were treated with lime after the overflows stopped and the street was cleaned."
