| Details: | SUMMARY: partially dewatered 48" main DETAILS: Wilsonville partially dewatered their 48" main to send divers in to ascertain whether any damaged occurred from the nearby road construction. None had. Standard diving practice took place, in that divers and tools were chlorinated. (Out of curiousity they took two coliform samples prior to flushing, one came back TC+.) They flushed the pipe with three-times the pipe-volume, then took 5 coliform samples. They then took second set of 5 (from each hydrant on the 500 of isolated pipe) on Friday August 7th. |
