New Technology Solves Age-Old Problems at Fort Sill


Four and eight-inch Watts model 957 RPZ backflow preventers protect the domestic water system. Strainers installed upstream of the RPZs help keep debris from getting into the OneFlow system and backflow preventers.

Physical water treatment
Mills continued, “The Army Corps of Engineers started doing their homework, researching different means of scale removal.”

What they already knew was that the system must handle a huge volume while being cost effective. Mills added, “There was the need for tolerance to huge pressure drops as well. And, according to the Buy American Act, the equipment would need to be American-made.”

With those mission parameters, and after a careful study of their options, the Army Corps of Engineers chose Watts’ OneFlow® anti-scale central treatment system. This uses TAC (template-assisted crystallization) technology. TAC falls into a category of water treatment often referred to as Physical Water Treatment (PWT).

The primary goals of PWT are to eliminate the use of chemical additives, reduce or eliminate discharge and waste water, and to create zero pollution while minimizing installation and maintenance costs.

The environmentally friendly technology behind leading TAC treatment systems was developed in Germany about 15 years ago. It was used throughout Europe for several years before coming to the US, and continues to be the dominant form of commercial water treatment there. TAC media starts out as polymeric beads (resin) in the 20 to 40 mesh size range. Catalytically active sites or templates are “imprinted” or coated on the bead surface through a batch-coating process.
