| The
most effective pipe cleaning and maintenance program
available for water distribution systems!
Unique in the industry, InfraMetrix's computerized
UDF program results in immediate and long-term solutions
to water quality concerns by systematically removing
stagnant water and deposits that collect inside water
mains.
Unlike
traditional, reactive spot hydrant flushing that did
not control water routing and utilized large quantities
of water unnecessarily without achieving effective scour
velocities, our UDF program is an effective tool for
closely managing the systematic flushing of your water
distribution system.
By
merging your utility's GIS database and hydraulic model
for the distribution system, our trained engineers use
UDF software to generate the flushing sequences. The
field journals produced show which fire hydrants and
watermain valves should be manipulated to assure and
optimize a proper cleaning.
For
each flushing zone, an optimal program of flushing sequences
is developed, and valves and fire hydrants are selected
to facilitate systematic, unobstructed cleaning. The
hydraulic impacts of each sequence are verified to avoid
excessive pressure drops.
