The Conn Pump Station provides potable water from the south of the city to just south of Mid-Cities Blvd 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.

Funding Source: Certificates of Obligation.

The pump station design recommendation for variable speed pumps increased the base project cost, and an increase in
construction prices overall caused the construction bids to exceed the project estimate. Surplus funds from UT1607 are
proposed to offset the deficit and to provide for a project contingency.
