Pumping the water out

摘要

Oconee County Quarry I outside of Walhalla, S.C. county-owned rock quarry, providing more than 2,500 tons of crushed rock daily for county needs as well as those of contractors and the general public. If rainwater and runoff from nearby springs are allowed to collect in the quarry, operations slow or even stop - making water removal a constant necessity. Since digging began in 1979, Oconee County had relied on a single Gorman-Rupp S4D110-hp submersible electric pump to keep the water out of the bottom of the quarry. In heavy rains, the quarry utilized two side-by-side pumps to keep the water at a manageable level and the digging operation ongoing.
