Details: SUMMARY: Sanitary Survey Tracer Study Requirement Document DETAILS: HBH representing DWP received notice that the USFS Tiller Ranger Station treatment plant required a Tracer Study. A contact Tracer Study was performed on the system. The flow rate from the plant was 32 gpm. All contact time was derived from pre-chlorination with a dilute solution of 12 Percent hypochlorite through the body of the plant, with some incidental time contribution, from a short segment of the distribution service line. The C10 was achieved 86 minutes into the study. The Tiller Plant should have adequate contact time under almost all circumstances. The CT Study data was issued as a completed report as of September 18, 2007. ACTION NEEDED: Continue communication with the Tiller Ranger Station operator in the event a question regarding the study or technical assistance is requested.
