MEMORANDUM
DATE: August 14, 1995
TO: The Honorable Mayor and Board of City Commissioners
FROM: James W. Shira, P.E.
City Engineer/Utiliti- irector
SUBJECT: Design Proposal-Forest Oaks and South Water Treatment Plants
Well Pumps and Ground Storage Tanks
Attached for your review and approval is a proposal from Professional Engineering Consultants,
Inc. (PEC)for work involved in the design of the well pumps, ground storage tanks, yard piping
and corrosion control chemical feed equipment that is required to utilize the two new wells
currently being installed.
In accordance with Chapter 17-551 F.A.C., we performed a corrosion control monitoring
program and determined that several of the monitoring points exceeded the Action Level for
copper content in the water samples. We did not exceed the Action Level for lead content in any
of the water samples. We then awarded a contract to Malcolm Pirnie, Inc. on March 15, 1994 for
the preparation of an Optimal Corrosion Control Plan as required by 17-551 F.A.C., in order to
bring the copper corrosion rate to within acceptable parameters.
On June 9, 1994 the Optimal Corrosion Control Plan was submitted to the Florida Department of
Environmental Protection for their review. On February 8, 1995 we received authorization from
FDEP to begin design and permitting for the modifications recommended by the report.
The proposal submitted by PEC includes the work required by the Optimal Corrosion Control
Plan, and uses Malcolm Pirnie as a sub-consultant. In this way, we will accomplish two goals
simultaneously. First, we will prepare plans and specifications for the well pump, ground storage
tank and connecting yard piping at each water plant to make use of the well that is currently being
drilled. Second, we will include in those plans the recommended improvements found in the
Optimal Corrosion Control Plan, so that construction of those improvements can be completed
within the timeframe mandated by Chapter 17-551 F.A.C.
PEC will design the well pumps, ground storage tanks, yard piping and corrosion control

modifications at both the South and the Forest Oaks Water Treatment Plants for a total not-to-
exceed fee of$108,497.00, and will have the design completed within 120 days of notice to
proceed. The preliminary estimated construction cost for these two projects is $985,000.00
I recommend that the City Commission authorize the Mayor and City Clerk to execute Addendum
No. 95-2 in the not-to-exceed amount of$108,497.00 in accordance with PEC's proposal dated
June 30, 1995.

RE: Forest Oaks and South Water Treatment Plants
Well Pumps and Ground Storage Tanks
Dear Mr. Shira:
We are pleased to present the attached proposal for Engineering Services related to the
above referenced assignment. The purpose of this assignment is to provide construction
plans, specifications, and related bidding documents for the construction of the following:
Forest Oaks WTP - New water supply well pump, controls, yard piping,
chlorine feed station, new 0.6 mg ground storage tank and
chemical feed equipment and storage to provide pH
adjustment to 8.0.
South WTP - New water supply well pump, controls, yard piping, chlorine feed
station, new 0.6 mg ground storage tank and chemical feed
equipment and storage to provide pH adjustment to 8.0.
A new well pump control system will be designed for each water treatment plant to allow
either ground storage tank to be selected as the lead tank. The lead ground storage tank
will control the operation of the well pumps. Previous water treatment plant design work
that has been completed by PEC will be utilized as much as possible.
The South WTP will not require a drainage permit, however, the Forest Oaks WTP will
require a MSSW permit from the St. Johns River Water Management District. Manhours
have been included to prepare the MSSW permit application, and the preparation of a
grading plan for the Forest Oaks WTP has also been included.
This proposal has been prepared based on the premise that the proposed construction
improvements will be completed under one contract document. This assignment consists
of two (2) primary activities:
1. Final Design
2. Bidding Assistance

Re: Scope and Fee for City of Ocoee Water Treatment Plants Corrosion Control
Chemical Feed System Design
Dear Ken:
Per your review and our telephone discussions we have revised the scope of work and fee
estimate to reflect the following changes:
• Autocad technician and PC time have been reduced per City comments.
• Construction Administration and Operations Assistance scope and budget
have been deleted.
Revised scope reflects three tasks: preliminary design, design and bidding services. The total
estimated fee is now $60,650. Table 1 details the hours and costs per task and is consistent
with the scope.
Very, truly yours,

City of Ocoee
Corrosion Control Chemical Feed System Design
13ackgroundi
Malcolm Pirnie, Inc. prepared a Desktop Evaluation for Lead and Copper Corrosion
Control, dated June 8, 1994. This report was accepted by the City and was submitted to the
Florida Department of Environmental Protection (DEP) as part of the City's requirements
under the Lead and Copper Rule (USEPA, June 1991) for exceedance of the Action Levels
for copper. The DEP accepted the recommendation in the report on February 8, 1995. The
City now wants to complete the design of corrosion control chemical feed systems as part of
an improvement program for the two main water treatment.plants, Forest Oaks and the South
Plant. Malcolm Pirnie, Inc. will provide the services for the chemical feed systems to the
City's general consultant, Professional Engineering Consultants, PEC, on a subcontract basis.
General:
The Forest Oaks WTP is a 2.8 mgd facility using groundwater sources and provides
aeration for H2S control followed by chlorine disinfection. The South Plant is the same type
of plant but is a 4.2 mgd rated facility. The City also operates two other plants listed below:
• Kissimmee Avenue 4.2 mgd
• Jamela Avenue 3.5 mgd
These plants will be phased out per the Master Plan. Hence, the Forest. Oaks and South
plants will each have to be expanded to replace the capacities of the older abandoned
facilities. The chemical corrosion central feed systems need to be incorporated into the
expansion plans for these two plants.
Desktop Evaluation Recommended Conner Corrosion Control Plan:
The June 1994 Desktop Evaluation recommended a two-fold strategy for copper
corrosion control:
• pH adjustment to 8.0 with caustic soda (NaOH)
• Modify existing tray aerators to lower the dissolved oxygen in the water.
(The aerators can be modified by eliminating trays.)
Since the desktop was completed, another alternative to caustic soda has emerged
based on experiences at other Central Florida water plants. Namely, liquid chlorine, sodium
hypochlorite, a basic solution, can be used instead of chlorine disinfection and its basic
properties raise the pH. For systems needing an expansion of the gas chlorine systems which
1
require containment and scrubbing to meet OSHA safety code for chlorine gas, the sodium
hypochlorite can be an attractive alternative since only one chemical is added instead of two
with chlorine and caustic soda.
SCOPE OF WORK
I. Process Tests
Task 1.1 - Process Tests for Hydrogen Sulfide (H2S) Control
Conduct bench scale and lab tests to determine H2S oxidation and
disinfection/disinfection-by-products controls parameters.

Subject: Proposal, Foundation Soil Investigation, Prolio58'd'GtoundS ge Tank, The
Forest Oaks Water Treatment Plant, City of Ocoee, Florida (PN 95-057.5)
Dear Mr. Maederer:
As requested, we have prepared and are pleased to present this proposal for providing
geotechnical engineering services for the project referenced above. In preparing this proposal,
we have discussed the project requirements with you and reviewed a preliminary site layout. In
addition, we have reviewed soils information for the existing well.
Based upon information provided by you, we understand that the proposed construction will
consist of a ground storage tank. Plans for the storage tank were not available. However,
conceptually, we understand that the proposed tank will be approximately 74 feet in diameter with
a side water depth of approximately 19 feet.
In order to provide input to our evaluations, we propose the drilling and sampling of two (2)
Standard Penetration Test borings to depths of 50 and 100 feet. In addition, our scope of services
includes a modest laboratory budget to help characterize the soil materials encountered. A one-
dimensional consolidation test is planned to be performed on a sample of the clay stratum
(depicted in the log for the existing well) that will be significantly stress by the loads induced
by the proposed tank.
The field and laboratory data will be summarized in an engineering report which will include a
settlement analysis and recommendations for foundation support and foundation related site work.
We believe we can complete the scope of services discussed herein for a cost of$3,880.00 as
outlined on Attachment A. We would not exceed this budget without your prior authorization.
Should your agree with the proposed scope of services and related fees, please indicate your
authorization in the space provided below.
