Details: SUMMARY: Tracer Study Preliminary Visit #2 DETAILS: DWP conducted a water survey in March 2010 and required that a CT Study be conducted. System requested assistance from HBH to conduct the study. PLC modification is necessary in order to track and store flow and usage data. No effluent flow meter is installed (cost prohibitive at this time). I had phone conversations and I met with Ned Dausel and Jeff Bruce, Portland Engineering, to review PLC modifications that I suggested earlier this year and approved by Scott Curry, DWP. Jeff had questions and wanted clarity on what I proposed. Jeff will update PLC in early September to include tracking and storing of reservoir levels and calculate GPM flows in order to determine flow rates for the tracer study to be conducted this fall. I also reviewed tracer study procedures, verified dosage figures and chlorine residual ranges and reservoir levels and routine usage (two reservoirs) desired for the study. ACTION NEEDED: Determine what the peak demand is for the system based on data collection, discuss with Scott Curry and conduct tracer study.
