This powerpoint presentation demonstrates the practical applications of the hydraulic
model to operations of a water utility that result in
cost savings,
innovation, or a
change in the operational protocols.
Two examples are presented, the first being Helena, Montana, that included the following:
reviewed GIS geodatabase for missing data;
created shapefile for model junction nodes and assigned
elevation values;
defined water consumption by parcel and distributed to
model junction nodes; and,
connected tanks, pump stations, pressure reducing
valves, sources (model reservoirs), and other features to
pipes and junction nodes. The second example was Columbia Falls, Montana, and included the following: issue - city wanted to know best way to operate pumps
during fire flow event;
analysis
- Extended Period Simulation,
and Fire Flow Analysis;
determined
- well pumps set based on tank levels
problematic during high fire flows;
result
- changed pump on/off settings to
system pressure, and
improved response time and reduced pressure drop
at 1,500 gpm fire flow to less than 5 psi. Includes tables, figures.
