Public Works Conn Pump Station Pump and Electrical Rehabilitation UT2008
Project Description
This project is to reconfigure existing suction header piping and pumps to meet the Hydraulic Institute standard for pipe pumping
and to upgrade and reconfigure electrical components to meet the National Electric Code.

Project Justification
Conn Pump Station provides potable water from the south of the city to just south of Mid-Cities Blvd. The pump station provides
potable water and pressure to the distribution system through four pumps located on the site. Three of these pumps were replaced 6
years ago. Staff became aware of noticeable wear and tear on the pumps through inspections and failures. Freese and Nichols
Engineering group was hired to conduct a piping analysis to determine the cause for the premature pump issues. Through this
analysis, Freese and Nichols was able to determine that the pump issues were caused by the net positive suction head created by
the piping alignment on the suction side of the pumps. The suction piping has a 90 degree bend located too close to the pump on
three of the four pumps. The analysis also shows that the electrical panels will have to be moved to correct the alignment of the
piping and to meet clearance requirements from the National Electric Code.
