Details: | SUMMARY: CT for Thurston #2 transmission-- 2016 survey date DETAILS: The transmission line from Thurston #2 will actually be longer than the last calculation of effective contact time (to derive CT) for that water line. The new larger pipe volume will provide longer contact time than the earlier calculation. Thus, the last calculation is conservative and may continue to be used to calculate CT. The water system survey date was discussed and tentatively set for September 2016. ACTION NEEDED: none |
