The contractor Barnes is ready to do exterior piping work; council members asked staff to confirm piping, SCADA alarms and timing before work proceeds.
Mayor Kelly Halvey opened the May 21 meeting and invited a Kelly Chapel representative to brief the council on recent water-system troubles and proposed repairs.
