Scope of Services
Task H. Energy Analysis and Pump Optimization
H.1 Document Pump Efficiency Curves: FNI will coordinate with City staff to obtain pump efficiency
curves for all high service pumping units. FNI will review original shop curves and energy
consumption by pumping unit if available to document existing pump efficiency curves and
current best efficiency point (BEP). If necessary, FNI will contact pump vendors to try to locate
information on missing pump efficiency curves. The resulting curve data found will be
documented in the Energy Analysis and Pump Optimization Technical Memorandum.
H.2 Review and Document Historical Enerev Usage and Cost Structure: FNI will review available
information over the last five years on historical energy usage at high service and distribution
system pump stations including available SCADA data and energy billings. FNI will document this
information and identify any trends in the data. FNI will coordinate with the City and/or the
electric utility to document the existing cost structure including cost per KW -hr and peaking
charges including any seasonal, hourly, or locational variations.
H.3 Input Efficiency Curves and Energy Costs to Model: FNI will input the collected data on pump
efficiency curves and energy costs into the water model for use in energy modeling.
H.4 Expand Water Model to Include Supply Source Pump Stations: FNI will expand the existing
