To improve the reliability and resiliency of one of its most critical wastewater components, the Miami-Dade Water and Sewer Department replaced more than a mile of aging force main used to convey flows to its Central District Wastewater Treatment Plant. Installation of the new force main required constructing two large vertical shafts and a large-diameter tunnel beneath a portion of Florida’s Biscayne Bay.
