The project consists of all labor, materials, and equipment necessary for the removal, hauling, and proper disposal of the existing filtration media from six (6) filtration vessels. The media to be removed include gravel, garnet, granular activated carbon (GAC), and plastic filter materials. Following medial removal, each vessel shall be inspected for overall condition with attention to signs of corrosion, wear, and/or damage. Any internal areas of the vessels that have signs of corrosion or deterioration shall be repaired prior to the installation of new media to ensure the longevity and reliability of the filtration system. The project scope also includes the delivery, installation, and start-up services necessary to achieve the satisfactory operation of a complete, fully functional new filter media system. Detailed specifications including vessel dimensions, equipment details, and media layering can be found in Appendix H. The installed media levels must conform to the configuration shown in Appendix H. Prior to the placement of the new media, the contractor shall test the backwash and underdrain systems to verify proper function and integrity.
