REQUEST:
The Utility Department requests the City Commission's authorization to execute a Task
Order #1 of RFQ #005 /15BF with CPH, Inc. in the amount of $281,862.75 for the design
of Water Treatment Plant No. 1 Water Quality Improvements.
SYNOPSIS:
Improvements to the potable water treatment process at Water Treatment No. 1 on Northern
Way are required to meet Federal water quality parameters. The City is under a consent
order with the State to lower the levels of Total Trihalomethanes in the water distribution
system. This task order is for the design of those improvements.
CONSIDERATIONS:
This Task Order #1 of RFQ #005 /15BF is needed to initiate the Engineering Design for the
Water Treatment Improvements to Water Treatment Plant No. 1 (WTP1) that are needed to
reduce the levels of Total Trihalomethanes (TTHMs) at the remote sampling points in the
system. TTHM samples are collected at the four most remote locations in the City on a
quarterly basis and the results of these samples to are reported to the Florida Department of
Environmental Protection (FDEP).
In 2014, the Environmental Protection Agency implemented changes to the formula
methodology used to determine compliance - no longer could the results of the four
locations be averaged. Since that time we have unable to consistently remain below the
regulatory TTHM threshold of 80 parts per billion (ppb) despite implementing low cost
operational improvements and enhancements that improved TTHM levels but not on a
consistent basis.
Regular 601 PAGE 1 OF 3 - July 27, 2015
The inability to consistently be in compliance with TTHM thresholds triggered a Consent
Order from FDEP in April 2015 requiring the construction of water quality improvements to
come into compliance. These improvements must be completed by April 2017. The
quarterly notice of violation forms sent to all customers is also a result of the TTHM
compliance violations and they will continue to be sent every quarter until the TTHM test
result averages for four consecutive quarters are below the 80 ppb.
CPH was previously engaged to evaluate the operational changes and determine if other
opportunities existed that would bring us into compliance in lieu of the large capital
expenditures that were anticipated. We unsuccessfully exhausted all of those opportunities.
During this optimization process, CPH also evaluated the advantages and disadvantages of
the various treatment technologies used by surrounding utilities. A matrix of this evaluation
is attached.
Based on the information gathered to date, the current recommendation is to construct an
ion exchange unit at WTP1 that will remove the precursors that combine with chlorine and
form the disinfection byproducts including TTHMs. Included in this design proposal is a
pilot test of an ion exchange unit that will confirm the precursor removal assumptions
prior to proceeding with full design of the ion exchange process.
The scope of work for this water quality improvements task order includes engineering
design and permitting, electrical engineering, geotechnical, State Revolving Fund Loan
application assistance, Ion Exchange Pilot Testing and Assistance, and Bidding Assistance.
The fee for this scope of work is $281,862.75.
FISCAL IMPACT:
The cost for Task Order #1 Water Quality Improvements is $281,862.75 which will be
funded from the Utility Enterprise Fund. A preliminary estimate of the construction cost
is $6,000,000 and a Loan from the State Revolving Fund will be pursued for the
construction funding.
COMMUNICATION EFFORTS:
This Agenda Item has been electronically forwarded to the Mayor and City Commission,
City Manager, City Attorney /Staff, and is available on the City's Website, LaserFiche, and
the City's Server. Additionally, portions of this Agenda Item are typed verbatim on the
respective Meeting Agenda which has also been electronically forwarded to the individuals
noted above, and which is also available on the City's Website, LaserFiche, and the City's
Server; has been sent to applicable City Staff, Media/Press Representatives who have

The project site is at the existing Water Treatment Plant 1 located on Northern Way ne
Trctwood Park in the City of Winter Springs, Florida. The proposed improvements consist of t
construction of a total of five (5) concrete pads, each a roximatel-Lyi 14 feet in di
understanding that the pads will be located in the same area and are proposed to suppoi
Pquipment/machinery.
Terracon will perform a geotechnical investigation to facilitate foundation design of the proposed
improvements and construction • the Project.

Stake boring locations and coordinate underground utility clearance at the site,
Mobilization of truck drill rig and crew to the site.
Perform three (3) Standard Penetration Test (SPT) borings to a depth of about 15 feet in
the proposed concrete pad areas.
Perform visual classification and appropriate laboratory testing of the soil samples
obtained from the borings.
The exploration will be supervised by a qualified Geotechnical Engineer registered in the State
of Florida, and the results of the exploration will be presented in a geotechnical engineering
report. The report will address the following items:
Based on our �# resent scheih(ymgffmwmp7-T
project within about one (1) week of your authorization to proceed. We anticipate the field
portion of the study to be completed in approximately one (1) day. Engineering analysis,
necessary laboratory work, and report preparation should be completed within approximately
two (2) weeks after the completion of field work.
