Requested: Award the contract for the construction of the Pearson Pump Station
residual control improvements to Red River Construction Co. in an
amount not to exceed $1,700,000.
Background
Information: As the water provider, the City of Southlake is responsible for
maintaining drinking water quality throughout the distribution system
to all customers. Currently, the City purchases its water from the City
of Fort Worth through a Wholesale Purchase Agreement and is at
the outreach of their distribution system. The Water Division utilizes
best practices to prevent water decay as it is delivered from Fort
Worth to maintain optimal water quality throughout the distribution
system. These include the use of mixing systems in all of Southlake's
storage tanks, maximizing turnover in storage tanks, and frequent
flushing of dead-end water mains. The Water Division can only
prevent accelerated water decay but cannot currently increase the
chloramine level of the water received from Fort Worth.
The City of Southlake contracted with Freese and Nichols, Inc. (FNI)
to conduct a water quality evaluation of the City's water distribution
system. This evaluation would serve as the basis on how to address
water quality issues experienced during low -demand periods and in
locations furthest from the City's two delivery points from the City of
Fort Worth. As part of the 2017 Water Quality Evaluation Report,
recommendations were provided that include the installation of
residual control systems at the Pearson Pump Station to mitigate
these water quality issues.
Due to Southlake's operation preference, this project seeks to install
an on -site hypochlorite generation and injection system at Pearson
Pump Station. This system will inject hypochlorite into the supply line
that enters the two storage tanks at the Pearson Pump Station site.
As a result, water quality will be maintained throughout the
