Re: Durham County
Stirrup Iron Creek Lift Station Capacity Improvements
Fast Track Sewer System Extension Application (FTA 04-16 and FTSE 04-16)
To Whom It May Concern:
On behalf of Durham County Engineering and Environmental Services,and in accordance with 15A NCAC
subchapter 02T and the Division of Water Resources Minimum Design Criteria, please find enclosed the
following documents associated with the proposed modifications to the Stirrup Iron Creek Lift Station:
• Fast Track Sewer System Extension Application
• Flow Tracking/Acceptance Form
• Figure 1—Topographic Map
• Figure 2—Aerial Map
• Application Fee (Note:The fee check for$960 is written to cover the application fees for
two(2) projects that are being submitted by Durham County at the same time. The
other project is Slater Road Lift Station.)
Durham County is requesting authorization to construct for capacity improvements at the lift station
described as follows:
Installation of one (1) new 200 horsepower pump, replacement impellers and maintenance
service for two (2) existing 200 HP pumps, new level instrumentation, new electrical breaker
panels, variable frequency drives to power two of the 200 HP pumps, new pump control panel,
new HVAC equipment, temporary lift station bypass pumping system (during construction), and
all associated wiring,conduit and appurtenances.
The County proposes to accomplish this work in in two(2) phases:
Phase I—Install the larger impellers in two (2)existing 200 horsepower Yeomans submersible
pumps to increase the permitted firm capacity of the lift station from 3.6 MGD to 4.7 MGD.
Phase II—Install a third 200 horsepower pump to increase the firm capacity of the lift station to
6.5 MGD, and all other improvements described above.

•
An interim engineering certification will be provided after the completion of Phase I.
Please feel free to contact me at [phone] if you have any questions or require additional
information. I can also be reached at [e-mail].
Sincerely,
