2008-29 Task Order No. 25 Scope of Services Westside Water Treatment Plant Evaluation -City of Clermont This Scope of Services is Task Order #25 pursuant to the Engineering Consulting Services Agreement dated August 12th, 2003 between the City of Clermont, hereinafter referred to as "CITY", and Boyle Engineering Corporation, hereinafter referred to as "ENGINEER". A. Background The City of Clermont, (CITY) has requested Boyle Engineering (ENGINEER) to provide professional engineering services to assess implementation of a centralized water treatment facility to service customers Westside service area. ENGINEER will provide the CITY with adesk-top treatment alternative planning document with recommended treatment strategy, and present considerations for design and construction. Customer complaints for the CITY's Westside service area have typically concerned poor aesthetic water quality (from objectionable taste, odor and appearance at consumer taps). Water service has historically been provided by three separate groundwater wells dispersed throughout the distribution system. Raw water is presently dosed with chlorine to oxidize hydrogen sulfide (H2S), inactivate microbial contaminants (primary disinfection), and provide residual disinfection (secondary disinfection). While chlorination meets primary and secondary drinking water standards, additional treatment is needed to enhance finished water stability, and meet customer expectations for aesthetic water quality. Based on a preliminary review of existing conditions and discussions with CITY staff, treatment at a centralized facility offers advantages over treatment at individual well-heads. Foremost among these advantages include: capital and operations and maintenance cost savings, water security, ease of use as a remotely operated facility, opportunity to streamline operations, and leverage the CITY's resources for maximum benefit. This scope of work defines tasks for: ^ Reviewing existing water quality and treatment practices. ^ Sampling and analysis to field verify water treatment needs. ^ Identifying treatment methods capable of meeting the CITY's finished water quality goals. ^ Select treatment method based on cost and non-cost considerations. ^ Recommending a strategy for implementation. B. Scope of Services ENGINEER shall perform the engineering Scope of Services for the CITY as described herein. Task 1. Project Management and Meetings 1.1 Task Order Administration: Monitor progress of work to assure compliance with established schedule, budget and work quality requirements, and perform monthly invoicing. .

The West Side Potable Water System is supplied by three groundwater wells. The water quality in these wells has steadily deteriorated over their many years of service and the aesthetics of the water are less than desirable. The Engineering and Utilities Departments are working with Boyle Engineering to develop a treatment and distribution strategy to alleviate the taste and odor concerns on the West Side System. Boyle Engineering and the Staff are considering various treatment processes such as ozonation, anionic ion exchange, greensand filtration and forced-draft aeration. To determine the best, most cost-effective treatment solutions for the new facility, Boyle Engineering will perform an evaluation of the treatment methods and make recommendations based on cost and non-cost considerations. I recommend approval of the Task Authorization for Boyle Engineering to perform professional engineering services for the Westside Water Treatment Plant Evaluation for $53,581.00.
