Mason Farm WWTP Fermenter Mixing Improvements

The Project consists of furnishing all materials, labor, equipment, tools, etc. unless otherwise specified, for the complete and operable installation of: 1. Demolition of existing pipe and mixing headers and their associated structural supports inside the fermenter tank up to wall pipe connections. 2. Demolition of two submersible pumps and associated piping up to wall the fermenter wall pipes in the basement of the Old Digester Control Building. 3. Excavation and demolition of underground fermenter gas condensate pipe, as well as its associated drip trap in the basement of the Old Digester Building. 4. Optional removal and reinstallation of a 6-foot by 6-foot section of the concrete cover for the fermenter tank to provide easier access to the interior of the fermenter. This would include the associated PVC liner repair. 5. Installation of new mixing nozzles and associated pipe and supports in the fermenter tank. This includes spot repairs to the existing PVC liner as required. 6. Installation of a vertically mounted centrifugal chopper pump in the basement vault of the Old Digester Control Building, as well as required structural modifications to fit the new pump in the vault. 7. Installation of new pipe, valves and supports in the basement of the Old Digester Control Building. 8. Installation of new gas condensate accumulator and associated drain and vent piping improvements. 9. Repair and coating of corroded sampling hatches in the fermenter cover. 10. Electrical improvements for power and controls of new equipment. 11. Installation of new level and flow instruments and integration of new controls with the plant-wide SCADA system, as defined in the CITI scope of supply (Appendix C). 12. Inspection of Fermenter Tank as described in Specification Section 03 01 00. 13. And all associated appurtenances as described in the Specifications and as shown on the Drawings.
