PRV
A network monitors the “health” of
the whole system
Not a choice of just one, or two instruments
is really a system approach
24
How is the data usage
Creating a multi-dimensional network:
Provides a more robust system able to generate timely and accurate indications of a wide-variety of events and
changing conditions.
Allows system managers to be “on-top” of issues before customers experience them.
25
Why monitor Water Quality in
distribution system
Improved customer satisfaction and relations
Enhance system operation and reduce downtime
Lower Operating Cost
Saves miles of driving time for personnel
Hours of sampling and testing time
Frees up personnel for performing other important tasks.
Meet distribution monitoring requirements. Satisfy regulatory record
keeping and reporting requirements
Alert operators and managers to undesirable changes in water quality
Distribution and plant personnel can troubleshoot remotely
Distribution and plant personnel can identify trends and adjust
operating parameters more efficiently
Distribution Monitoring Panel
Monitors “indicator” parameters for
optimization or operational failures
