The Clean Rivers Project is DC Water’s ongoing program to reduce combined sewer overflows into the District of Columbia’s waterways; being the Anacostia and Potomac Rivers and Rock Creek. The Project is a massive infrastructure improvement designed to capture and clean water during heavy rainfalls before it ever reaches the public waterways. To create the massive underground structures that form the solution to combined sewer overflows (CSOs), tunnel boring machines are being used to excavate tunnels more than 100 feet underground. The tunnel boring machine (TBM) being used to dig the first portion of the project, bores a 26-ft-diameter tunnel and is more than a football field in length when fully assembled. Known as the Blue Plains Tunnel, this first section of tunnel is a 4-mile reach of the 13-mile Anacostia River Tunnel, stretching from the Blue Plains Waste Water Treatment Plant to the Main Pumping Station in downtown Washington, D.C.
Please join us for a presentation on the major works undertaken by Hayward Baker for the first phase of DC Water’s CSO infrastructure program which involved the use of Deep Mixing, Jet Grouting, SuperJet Grouting, and Compaction Grouting (or LMG). Work was procured through either design-build or design-bid-build contracts depending on the subcontract phase. Applications included independent SOE systems, support for micro-tunneling operations, ground-water control, utility protection, settlement protection and combined design-build SOE solutions.

Since then, Joe has managed projects in all types of specialty geotechnical construction. Joe has authored or co-authored over 10 papers on various subjects in geotechnical design and construction.
In his free time, Joe enjoys running and coaching youth lacrosse and basketball.
JOSEPH A. MANN, PE
After graduating from the University of Pittsburgh with a B.S. in Civil Engineering, Joseph A. Mann began his career in 2003 as a geotechnical engineer working for Paul C. Rizzo & Associates based in Columbia, SC. In 2005, he became a field engineer for Hayward Baker Inc. (HB) working on projects throughout South Florida and the Florida Keys. After 7 years in South Florida, Mr. Mann relocated to HB’s Mid-Atlantic office, located outside Baltimore, Maryland, where he works today. He has designed and managed ground improvement projects throughout the eastern United States and parts of Canada, specializing in both dry and wet soil mixing, jet grouting, compaction grouting, cement grouting, chemical grouting and polyurethane injection systems, micropiles and other deep foundation systems, ground improvement utilizing vibro systems, various forms of underpinning, and earth retention systems to provide support of excavation. A majority of Mr. Mann’s recent projects have required soil mixing and jet grouting, allowing him to form best practices utilizing specialty grouting techniques and data acquisition (DAQ) and control systems. Mr. Mann is a registered Professional Engineer in FL, MD, VA, and the District of Columbia.
