Hetland Prepared by: Allen Short/;s Utilities Director Water Division Manager Subject: Water Treatment Plant Upgrade and Ozone Pilot Study Recommendation: Adopt resolution authorizing the City Administrative Officer to negotiate a contract with the firm of Black and Veatch for professional engineering services for the upgrade of the City's Water Treatment Plant and Ozone Pilot Study and to award the contract if the cost does not exceed 125, 000 dollars. Background: All treatment plants, at one time or another, require a periodic review of their overall design and effectiveness with regard to the treatment process and water quality. Numerous changes in treatment plant design practices have evolved over the past 25 years. Many of the changes are subtle and are not readily apparent when casually viewing a new water treatment plant. Collectively these innovations have significantly improved the performance and reliability of plant operations. The City of San Luis Obispo Water Treatment Plant was constructed in 1963. Many of the equipment components have deteriorated. They do not perform effectively and efficiently. Obtaining spare parts is difficult and expensive. An equipment rehabilitation program can inexpensively upgrade the plant to provide reliable service with flexibility to implement efficient operational practices. As part of the City's Water Management Plan a section was devoted to critically evaluating each of the water treatment plant components. The City staff reviewed and analyzed the various treatment plant processes on the basis of improved operational efficiency and treatment capacity. The review identified specific problem areas and equipment components which were contributing to substandard plant performance and increased costs. The firm of Culp Wesner Culp Consulting Engineers was then retained to review and verify staff's analysis and to develop cost estimates for each of the proposed improvements. REQUEST FOR PROPOSAL On July 7, 1989 staff developed a request for proposal to upgrade the existing water treatment plant and perform an ozone pilot study. A total of eighteen (18) engineering consulting firms were contacted; the City received seven (7) responses. Those firms are listed below: Brown and Caldwell Black and Veatch ��h��►�Ni►�IIIIIII�P°�'��I�II MY Of say r LUIS OBISPO AMIGA COUNCIL AGENDA REPORT Page 2 John Carollo Engineers HDR Metcalf and Eddy CH2M Hill James M. Montgomery Engineers To fully evaluate each of the proposals a screening committee was established. The committee consisted of the Utilities Director, Water Division Manager, and the Water Treatment. Plant supervisor. Additionally, the following list of criteria was established to fully and specifically compare each of the proposals. The RFP scope and overall understanding of the City's needs. The ability to innovatively meet the new filtration regulation. The total overall project costs. Based upon the screening process the list of firms was shortened from seven (7) to four (4) . On August 7, 1989 each of the four finalists participated in a formal interview and presentation. The formal presentations were carefully evaluated by the selection committee using the following criteria: Knowledge of the State of California new Filtration regulation rules. Qualifications of project team Presentation and professional skills Technical knowledged and past project experence. Innovation, understanding of City needs and requirements. After the presentations were concluded the selection committee than met to review each of the finalists proposals and projected cost estimates. Based upon previously established criteria, needs and goals of the City, available support and staff expertize, the selection committee is recommending that the firm of Black and Veatch be retained to perform the required engineering services. A copy of Black and Veatch's proposal is available in the Council reading file for your review. FINANCIAL IMPACT: Based upon prior analysis and cost estimates, $1.6 million was approved in the 1987-89 Financial Plan and an additional $560, 000 is in the 1989-90 Capital budget. In 1988 the City sold just under $5.0 million in water certificates of participation (bonds) to finance the project. The cost for Black and Veatch to conduct the design study and pilot work is 125, 000 dollars. �,In��N��u�IIIII�pn�uglU�D city of sari tins OBISPO = COUNCIL AGENDA REPORT Page 3 . CONSEQUENCES OF NOT TAKING ACTION: The treatment plant will continue substandard performance and increased treatment costs. The plant may have difficulty meeting new and more stringent water quality regulations as they are imposed. If the money from the bond sale is not utilized within a three year time frame the money will be returned. ACTION RECOMMENDED: Adopt resolution authorizing the City Administrative Officer to negotiate a contract with the firm of Black and Veatch for professional engineering services for the upgrade of the City's Water Treatment Plant and Ozone Pilot Study and to award the contract if the cost does not exceed 125, 000 dollars. i I i C�-3-3 ��nur i�iIIIIIII�Iin i��U City Of sarrlUIs OBIspo AffAm�a COUNCIL AGENDA REPORT Page 4 APPROVED: City A inistrative Officer City Attor y Finance Director Ili l� l - 4CRxi Utilities Director Water Division Manager ATTACHMENT : Resolution I i' C RESOLUTION NO.
