Sand Company Cuts Freshwater Consmption by Over 50%
The mines, which are located in Maiden Rock, Bay City, and Menomonie, Wisc., are recapturing, recycling, and reusing nearly all of the process water following significant capital investment in new technology such as thickener tanks at the Menomonie and Bay City mines. The tanks draw silt and clay from the wash water so the water can be recycled and reused.
The Maiden Rock mine is using only 42 percent of the average amount of water allowed under its high-capacity well permit issued by the Wisconsin Department of Natural Resources. The Bay City mine is using only 17 percent of its permitted amount; the Menomonie mine is using just 15 percent.
