Sewer Lift Station Protected With Crystalline Waterproofing

摘要

Wastewater treatment for the new Roaring Fork Club expansion project in Basalt, Colo., will be provided by the Basalt Sanitation District using a gravity sewer extension. The 383-acre private club is expanding its facilities with 13 new, larger cabins as well as a 43-unit employee village. A key component of the project is a 14-ft-tall, cast-in-place lift station requiring approximately 42 cu yds of ready-mix concrete. Sopris Engineering specified Xypex Bio-San C500, a new dual-protection admixture, to protect the lift station from an expected hostile hydrogen-sulfide environment, microbial-induced corrosion and varying pH levels. According to Sopris Design Engineer Paul Rutledge, the firm would previously have considered an epoxy coating for the interior of the lift station; however, that option is no longer its first choice.
