The work consists of furnishing all equipment, materials, labor and performing all operations required for the replacement in kind of the two (2) unwatering pumps, three (3) station drainage pumps and all associated piping, valves, supports, wiring, controls and associated equipment and enclosures within the unwatering and drainage sumps at Harry S. Truman Project. The work also includes new discharge riser piping for submersible pumps and incidental related work. Controls and monitoring will be integrated into the existing SCADA network by others, but must be fully cyber compliant, functional as a stand alone system, and with connection points to allow further integration. This work will also include modifications as required to enlarge the openings (as indicated on the drawings) and new covers for the enlarged openings and preparation of the edges to allow for a recessed cover plate or grating similar to the existing condition.
