| InfraMetrix's
experienced field technicians can execute the UDF program
— or assist and train your utility's
work forces.
With a well-prepared UDF program, less time
is spent in the field trying to cope with often surprising
conditions such as missing or inoperable valves and
hydrants. For executing the UDF program, a field journal
containing graphical and technical data sheets is used
for guidance as well as to note pertinent information
such as pressure and flow, water quality, asset status
and flushing time.
During
the flushing, InfraMetrix field technicians operate
and shut the fire hydrant when the desired water quality
results are obtained. This assures that the least amount
of water is used for each sequence and that crews are
optimizing their efforts and time by avoiding unnecessary
flushing of potable water. Field crews will also validate
the routing of the sequences and update the location
map for the assets used.
Your
report
After the UDF program is executed, we present a comprehensive
report including updated field journals, ODBC database,
GIS mapping, and all findings and results. Acknowledging
discrepancies between the in-house (theoretical) and
field (observed) conditions is important when maintaining
and updating the database and flush sequences.
Prepared
by our engineering department, the report includes:
| + |
Water
quality tests results, allowing the utility to pinpoint
problem areas where further actions may be required. |
| + |
Water
velocities for each sequence, enabling the utility
to validate the effectiveness of the program. |
| + |
Comparison
between real and theoretical flush times (and volume
of water used), allowing seriously encrusted pipes
and/or system piping configuration anomalies to
be identified. |
| + |
Remarks
and recommendations including findings such as pipes
sections impossible to flush and/or flushed more
than once. |
| + |
Updated
GIS map of the water distribution system showing
confirmed fire hydrants and valves used, water velocities
achieved, as well as assets not used for further
maintenance programs. |
| + |
Revised
field journal considering the changes of the field
crews. |
| + |
Updated
ODBC database. |
