October 11,2001 Ms. Tamara Richardson, P .E. City Engineer City of Clermont 1 Westgate Plaza Clermont, Florida 34712 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, . Attachments CWD/smalOO-OO7.04/corresp/ RichardsonS.czf.doc 201 EAST PINE STREET' SUITE 1000 .

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. L TS/skalsmalcorresp/Scope of ServicesS.doc HAI#00-007.04 - 1 - 101100 ., . . . . . 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.
