Work includes rehabilitation of the water treatment system. The treatment improvements consist of adding liquid ammonium sulfate (LAS) for disinfection. The proposed scope of work includes revisions to the well header piping to accommodate new inline static mixers equipped with chemical injection ports for each disinfectant. A new chemical building is also proposed at each well site to store the LAS double wall storage bulk tank and the chemical feed system. Work completed under this contract will require the water treatment plant to remain operational until work is completed. See attached file.
