Narrative
A 2-inch plastic main with one-way feed was ruptured by a county water & sewer crew while performing maintenance work. Once the incident was made safe it was identified that mud, water and debris had entered the downstream gas pipeline where crews began running a cleaning pig to clean the pipeline where it was determined that satisfactory results were not being obtained. At this point during evaluations it was determined that the affected pipeline should be replaced where cost of replacement was the direct results of the incident and not improvements to the existing system where the additional cost resulted in the incident exceeding the $50,000 threshold for reporting. Notification of excavation by the excavator was not made to the one-call center before damage occurred.
