The areas <br />of the City’s water treatment facilities to be studied will include the iron and manganese filtration <br />water treatment facilities, the granular activated carbon (GAC) water treatment facilities, and the <br />Advanced Oxidation Process (AOP) water treatment facilities. The project team includes Steve <br />Nelson, P.E. John Lapointe, and Daniel Papp from WSB. <br /> <br />The WSB Team will review the previous maintenance that has been done at each of the facilities <br />described above before developing a timetable and estimated costs to rehabilitate them for the <br />next 20 years. We will also study the City’s water demands for the next 20 years and determine <br />when, or if, new water treatment facilities will be needed and include an estimated timetable and <br />costs for these improvements. <br /> <br />The following scope of work will be provided for this project: <br /> <br />SCOPE OF WORK <br /> <br />1. Review previous maintenance records and reports for the City’s water treatment facilities. <br />These records will be used to rank and prioritize when future improvements are needed for <br />each of these facilities. <br /> <br />2. Review the City’s historical and projected water demands for the next 20 years to <br />determine and illustrate when additional water treatment capacity is needed. <br /> <br />3. Inspect the process components of all water treatment facilities and provide the following <br />analysis. <br /> <br />a. Review and document the existing conditions of existing process equipment <br />including both the iron/manganese removal and GAC filters, AOP equipment, high <br />services pumps, and chemical feed systems. A manufacturer service <br />representative will be coordinated to sample and analyze media from the filters. <br /> <br />b. Review and document the existing conditions of the controls, electrical <br />components and generator, to include; developing cost estimates for automating <br />the operation of the iron and manganese removal pressure filters with <br />automatically operated valves with electric actuators and associated controls. An <br />evaluation of adding digital differential pressure transmitters serving the <br />iron/manganese removal filtration system will also be provided..
