X-611 Water Treatment Plant

The X-611 Water Treatment Plant has the design capacity to process 40 million gal/day but typically processed over 10 million gal of water daily for the plant’s recirculating cooling water system when the gaseous diffusion plant was in operation. Assuming the average person uses 80-100 gallons of water per day (U.S. Dept. of the Interior U.S. Geological Survey (https://water.usgs.gov/edu/qa-home-percapita.html)), the typical operational level of 10 million gal/d at the X-611 is enough water to regularly service a city of 100,000 people. The total capacity (40 million gal/d) is about four times that much.

The water treatment process is based on conventional water treatment techniques, which include softening, coagulation, flocculation, sedimentation, filtration, chlorination, and pH adjustment. The X-611 Water Treatment Plant was used as a model during planning of other local water treatment plants.

The raw water that is treated at the X-611 Water Treatment Plant comes from the Scioto River via the X-605A Sanitary Wells and the X-608A and B Well Fields.

The X-611 Water Treatment Plant consists of two concrete-block houses, a series of mixing and settling basins, and the necessary chemical storage bins. The main building, which houses the lime slackers, ferric sulfate feeders, activated carbon feeders, a chlorinator, and the office and laboratory areas. The filter house houses the sanitary water filtration and pumping facilities.
