City Councilman Scott Sherman wants significant changes at the San Diego Water Department. Sherman’s call for action came Oct. 16, during a city council discussion of an independent audit of the problem-plagued department. That audit, along with reporting by the NBC 7 Responds team, uncovered significant delays in the department’s effort to replace broken water meter boxes and lids. Auditors also discovered that some department employees were working less than four hours of their eight-hour workday.
