Hydraulic Analysis Report
For
(Project Name)
The Hydraulic Analysis Report for (Project name) dated (Date); has been completed by (Engineers
Name) for (Owner/Developers Name). This report is prepared in compliance with existing City Code,
Utility Tariffs, and the latest revision of the Colorado Springs Utilities Water Line Extension and
Service Standards.
This Report does not reserve capacity in the water system until a building permit is obtained.
Significant changes to the development plan will require an addendum to this Report.

Date WPD Data Request Form received:
Is Hydraulic Analysis Report (HAR) Required?
Per the HAR Review Process flow diagram, please verify fire flow requirements w/ CSFD; Complete and
submit HAR to UDS. At the time the HAR is submitted to UDS, please also submit UDCF through DDS, and
notify WPD of UDCF Receipt number.
Information required for Hydraulic Analysis Report (HAR):
Pressure Zone(s):
HGL at Max Day Demand (lowest system pressure):
HGL at Min Day Demand (maximum system pressure):
Max Day to Average Day (MD/AD) peaking factor:
Offsite Demand:
Looping Requirements: A minimum of 2 connections are needed for looping, for redundancy and water
quality purposes. The location of the proposed connections, source HGL, are shown in the screenshot attached.
If you would like to connect in other locations, please let me know.
For model positioning, please use the following FIMS Coordinates (not intended for design purposes), for
the proposed connections points:
Existing System Notes: Please note that for pressures 170 psi or greater, DIP is required.

be used for design purposes. Colorado Springs Utilities accepts no liability if the provided coordinate is used for design purposes.
**The Fire Flow information above is provided solely as a reference. An official Fire Flow report must be requested by the engineer
and provided by Colorado Springs Utilities Water Planning prior to sign off of construction plans by Colorado Springs Utilities and
Colorado Springs Fire Department.
Please verify fire flow requirements w/ CSFD prior to Construction Drawing submittal. At the time the
Construction Drawings are submitted to UDS, please also submit UDCF through DDS, and notify WPD of
UDCF Receipt number, along with hydrant flange elevations and required fire flows.

Date HGL Request Form received:
Is Hydraulic Analysis Report (HAR) Required? No
Because the site is more an infill project, an HAR will be not required. Colorado Springs Utilities will calculate available fire flow
upon Construction Drawing submittal.
Please verify fire flow requirements w/ CSFD prior to Construction Drawing submittal. At the time the Construction Drawings are
submitted to UDS, please also submit UDCF through DDS, and notify WPD of UDCF Receipt number, along with hydrant flange
elevations and required fire flows.
Developer/Engineer can model available fire flow prior to Construction Drawing submittal using the following HGL information. See
HAR Modeling Requirements on requirements for fire flow modeling.
