Ensures valves and hydrants are operational, not leaking and in proper position

Our team aggressively PMs over 750 valves a year

This represents 7.5%  of the system

Water Distribution MaintenanceWater Distribution MaintenanceToday the leak detection team consists of a 3 man crew armed with state of the art leak detection equipmentq p

The crew uses 60 programmed data loggers to monitor an area

If the data loggers register a possible leak, the team will use a correlators to pin point the leak

Once the leak has been found the team will repair the leaksOnce the leak has been found the team will repair the leaks and capture the leak attributes
