Water Distribution MaintenanceValve and Hydrant PM Programy g
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

Why CIPPPros
• Trenchless Technology
Cons
• Reduces pipe• Trenchless Technology
• No spoils
• Reduces Infiltration
• Reduces pipe diameter slightly
• Very strict and exact
• Increases Flow Capacity
• Less expensive than traditional open trench
process
• Point repair may be required prior to traditional open trench
methods in many cases
• Faster
