Subject:
Convenion to Sodium Hypochlorite Feed Systems
Six (6) Existing City Facilities
Dear Ms. Richardson:
.
Hartman & Associates, Inc. (HAl) is pleased to submit two (2) signed copies of the revised
proposal to convert six (6) existing treatment plants to liquid sodium hypochlorite feed systems
from the current chlorine feed systems. The proposal has been revised to add the Hancock Road
WTP to the project scope. The addition of this WTP increased the number of facilities from five
(5) to six (6). The estimated capital costs for the project has been adjusted to add the cost for the
Hancock Road WTP conversion and to escalate the previous estimates for increases in
construction costs since the previous estimate was prepared approximately one (1) year ago.
HAl's engineering fee has been modified to reflect the additional effort required to include the
Hancock Road WTP and to utilize HAl's current rate schedule, which was modified in July 2001.
HAl appreciates the opportunity to provide this proposal for the conversion of the disinfection
feed systems. We are available at your earliest convenience to meet with Mr. Saunders and
yourself to discuss the changes that were made in the revised proposal. If you have any
questions, please contact me at 1-800-881-3955, extension 122.
Very truly yours,
.

ENGINEERING SERVICES FOR LIQUID SODIUM HYPOCHLORITE FEED SYSTEMS
FOR THE SEMINOLE, FOURTH STREET, GRAND HIGHWAY, HANCOCK ROAD AND
GREATER IDLL WATER TREATMENT PLANTS AND THE WEST W ASTEW A TER
TREATMENT PLANT
PROPOSED SCOPE OF SERVICES
October 11, 2001
GENERAL DESCRIPTION
The City of Clermont owns and operates five (6) separate water treatment plants (WTPs) and two
(2) wastewater treatment plants (WWTPs). The Seminole, Fourth Street, Hancock Road and Grand
Highway WTPs each include a single "high service well" that pumps directly to the distribution
system while the Greater Hill has two (2) high service wells. All of the WTPs include gas
chlorination facilities. In view of the recent EP A regulations related to the storage and handling of
chlorine gas (Le. 40CFR68, Risk Management - Accidental Release Prevention), the City has
elected to provide facilities at each WTP for liquid chlorination using commercial grade sodium
hypochlorite, with the facilities designed such that retrofit for on-site generation of sodium
hypochlorite is feasible in the future. The initial phase of this program involves installing
hypochlorite facilities at the Seminole, Fourth Street, Grand Highway, Hancock Road and Greater
Hill WTPs
In addition to the WTPs, the City owns and operates two (2) WWTPs known as the "East WWTP"
and "West WWTP," respectively. The East WWTP is being upgraded and expanded and
hypochlorite facilities are included in the upgrade and expansion program. The West WWTP is not
part of any planned near term capital improvement program; therefore, hypochlorite facilities are to
be installed at this facility concurrently with the systems for the five (5) WTPs.
In summary, this project involves the installation of sodium hypochlorite feed systems at the
Seminole, Fourth Street, Grand Highway, Hancock Road and Greater Hill WTPs and at the West
WWTP. It is proposed that each system will involve hypochlorite storage and feeding systems,
secondary containment facilities and related piping, valves and electrical components. Also, each
of these systems will include a building to house the feed systems and tankage, with space allocated
for future on-site generation units, if desired by the City. To provide the most ideal and
conservative design approach, HAl will base the preliminary construction cost on including a
building to house the chemical feed equipment, bulk storage tank, and electrical equipment. The
building and chemical feed equipment will follow the same design considerations that were used for
the recently completed liquid sodium hypochlorite feed system for well site No.4 From an
engineering standpoint, the focus of this authorization is to provide preliminary design, final design,
permitting, bidding and construction phase services for the facilities described above. Services to
be pro~ided by HAl are outlined below.

TASK 1: PRELIMINARY ENGINEERING
Initially, HAl will gather and review operating records, raw water quality data, chlorine feed rate
data, planning documents, flow projections, and as-built drawings and visit each WTP and WWTP
addressed in the project. Subsequently, HAl will evaluate the gathered information, estimate
hypochlorite dosages and feed rates for existing and projected flows, and size chemical feed
equipment and hypochlorite storage facilities for each plant. Further, HAl will develop preliminary
site plans, floor plans and cost estimates for each facility. HAl will present the basis of design, site
plans, floor plans and estimated costs in a "Technical Memorandum" that will be submitted to the
City for review and comment. HAl will attend one (1) meeting with the City to discuss the
memorandum and obtain a consensus regarding the size and configuration of the systems prior to
beginning final design.
TASK 2: FINAL DESIGN
Upon acceptance of the Design Memorandum by the City, HAl will initiate the final design of the
Project of the six (6) hypochlorite systems. The proposal is based upon the preparation of one set of
design documents for the six (6) facilities. The proposal is based upon one (1) construction contract
for the work described in this proposal. The final design phase will result in preparation of the bid
documents, engineering drawings, and specifications, which will be submitted to the City for review
at 60%, 90% and 100% completion levels. Four (4) sets of drawings and specifications will be
provided to the City for each review. Also, a final cost estimate will accompany the final design
documents. To ensure proper design of the facilities, HAl will obtain approval fÌ'om the City for
any substantial changes in the preliminary design prior to incorporation in the final design.
TASK 3: PERMITTING
HAl will prepare and submit permit applications and supporting documentation to FDEP on behalf
of the City to secure permits for construction of the hypochlorite storage and feed facilities. Any
permit application fees are to be provided by the City. HAl will also make a submittal of the final
construction drawings to the City's Building Department and attend one (1) meeting with the
Building Department and the City's Engineer to review any comments made by the Building
Department. The submittal by HAl will be for review purposes only. The Contractor shall be
solely responsible for all building permit fees and obtaining the building permit for the project.
TASK 4: BIDDING
Upon authorization to proceed with the bidding and award phase of the project, HAl will complete
the following tasks.
A.
Coordinate advertisement of the Project and issue Bidding Documents to prospective
bidders.
B.
Attend and conduct a pre-bid conference and prepare minutes of the pre-bid conference.
C.
Respond to any questions fÌ'om bidders and prepare and issue addenda as required to
interpret, clarify or expand the Bidding Documents.

contract. For this phase and the other phases of the project, the services are based upon all six (6)
facilities being constructed under one (1) contract. During this phase, HAl shall consult with and
advise the City and act as the City's representative. All instructions to the Contractor will be issued
through the City, with the consultation and advice of HAl, provided on an as-needed basis. During
the construction phase, HAl will:

significant construction activity.
Provide interpretation or clarification of the design documents when requested.
Review shop drawings and other submittals up to two (2) times per submittal for general
conformance with the Contract Documents.
