The Water Treatment Plant provides water treatment for all water entering PORTS. This facility is part of PORTS, which was a part of the U.S. Cold War nuclear weapons complex. PORTS primary Cold War era mission was the production of highly enriched uranium by the gaseous diffusion process for defense/military purposes. The plant has the design capacity to process 40 million gallon/day (gal/d). Assuming the average person uses gallons of water per day (U.S. Dept. of the Interior U.S. Geological Survey), the typical operational level of 10 million gal/d at the is enough water to regularly service a city of people. The total capacity (40 million gal/d) is about four times that much, emphasizing the need for PORTS to be able to support critical Cold War mission.

This Water Treatment Plant HAER was completed in PORTSMOUTH GASEOUS DIFFUSION PLANT, WATER TREATMENT PLANT HAER No. OH-142-R (Page 3) Part I. Historical Information In support of this report, there are three appendices: Appendix A through C, which consist of survey photographs, historical photographs, and historical drawings, respectively.
Construction History of the Water Treatment Plant: Peter Kiewit Sons Construction Company subcontracted the construction of the Water Treatment Plant to the Central Contracting Company of Oshkosh, Wisconsin. Excavation activities and foundation work for the Water Treatment Plant began in September and continued through the winter of (Appendix B, Figures 4 through 8). The schedule of construction began with the sanitary water facilities, followed by the secondary settling basins, primary settling basins, chemical storage building, and the slow-mix basins. In February workers began erecting structural steel for the chemical storage building (Figure 9).
By mid-June workers had completed much of the concrete work for the settling basins (Figures 10 and The following month, workers began excavation of the sludge ponds (Figures Electrical and mechanical work transpired from late October through early November at which time Central Contracting Company and its subcontractors had largely completed the Water Treatment Plant (Figure Historical drawings of building plans are provided in Appendix C (Figures 14 through Part II. Site Information Description of the Water Treatment Plant: The Water Treatment Plant is located in the northeast section of PORTS, just outside Perimeter Road.
The plant includes a chemical storage building; sanitary water filtering and pumping plant a recarbonation instrumentation building settling basins; and a storage basin. The Raw Water Pump House, located near the east bank of the Scioto River, pumped raw river water to the Water Treatment Plant for treatment. For many years, the plant s water has been pumped from the X-608A and B well fields which currently bypasses the pumphouse. In addition, a second well field, was added with the Gas Centrifuge Enrichment Plant. Water for plant operations is treated to reduce solids to no more than five parts per million.
The Water Treatment Plant has a capacity of gallons of water per day for plant operations; 36 million gallons per day for recirculating water make-up and gallons per day for sanitary water. Water for sanitary use receives further treatment at the Sanitary Water Filtering and Pumping Plant. Once treated with chemicals, concrete tanks, located east of the Plant, store the sanitary water prior to use. The Sanitary Water Filtering and Pumping Plant can treat gallons per day. Built with steel framing and concrete blocks, the Water Treatment Plant Chemical Storage Building stands two stories tall and encloses square feet of floor space. Utilitarian in its design, the building follows a simple, rectangular plan (Appendix A, Figures 1 through 3).
The roof consists of a flat, concrete slab that slopes from east to west. Fenestration at the first story is comprised largely of 15-light steel, industrial sash awning windows. Fenestration at the second story consists predominantly of 12-light steel, industrial sash awning windows. Pedestrian entrances are secured by hollow, steel doors. PORTSMOUTH GASEOUS DIFFUSION PLANT, WATER TREATMENT PLANT HAER No. OH-142-R (Page 4) The interior of the first floor includes a heater room, chemical feed room, storage for 1 ton chlorine containers, chlorine scales, chlorine feed room, laboratory, control room, and a restroom. The second floor includes a battery room and a bag storage room for chemicals. Also located on the second floor are the dry-feed machine extension hoppers and conveyor equipment.
This equipment feeds lime and ferric sulphate to the feed machine hoppers. A set of three chemical storage silos are located immediately to the east of the Plant. Built of concrete, the tanks stand 47' tall and have a diameter of The tanks store ferric sulfate and lime. Chlorine feed from the main building was discontinued, along with the use of ferric sulphate. The ground floor includes three lime slakers. A polymer is added to the raw water to aid in flocculation and settling of the solids. Large, semi-circular and square-shaped mixing and settling basins are located to the west and south of the Water Treatment Plant Chemical Storage Building. Built as a single, monolithic concrete structure, the basins cover an area of square feet.
The basins are arranged in two groups, with one serving as the primary group, and the second serving as the secondary group. The primary group of basins includes an influent line and meter vault, rapid-mix and slow-mix basins, and settling basins. The secondary group of basins consists of two slow-mix basins and four secondary settling basins, which serve as the final stage of water treatment. When water was originally sourced from the river, a butterfly valve at the Raw Water Pump House controlled the flow rate to the Water Treatment Plant. The flow is now controlled by starting and stopping wells in the two well fields. Water entering the Water Treatment Plant passes through one of three Venturi meters.
Two of the three lines empty into the primary rapid-mix basins, with the third line dividing its flow to the secondary rapid-mix basin and the rapid-mix bypass channel. As water flows into the primary rapid-mix basins, vertical shaft mixers maintain a steady mixture of chemicals and raw water. The secondary basins feature similar equipment as that found in the primary basins. These basins provided the additional treatment necessary for sanitary water when the plant operated on water pumped from the Scioto River and have not been used for active treatment since the The semi-circular shaped basin, located toward the southeast corner of the Water Treatment Plant, functions as an equalizing basin. This basin stores about 1 million gallons of process water.
Water depth in the equalizing basin varies from 7 to with surface area totaling about square feet. A 42''-diameter pipe connects the equalizing basin to the Water Treatment Plant effluent. The equalizing basin includes a 15' long overflow weir, which empties into a vitrified tile pipe. Influent and effluent from the basins is facilitated with manually-operated sluice gates. Sludge, generated by the settling process, exits the basins with the assistance of sludge return boxes and sludge pumps. Waste sludge is pumped into sludge lagoons located east of the basins.
