DigIndy Tunnel System Collection Consolidation Sewer Construction Update
Citizens Energy Group (Citizens) is implementing a long-term control plan to address combined sewer overflows (CSOs) in Indianapolis, Indiana. The “DigIndy” plan includes provisions for a series of CSO diversion structures, consolidation sewers, screen and gate structures, approach channels, drop shafts, and a tunnel for storage and conveyance. There are multiple tunnel segments and corresponding near surface projects planned over a span of 10–15 years. The paper discusses the overall tunnel system and highlights the recent near surface sewer projects. The projects are near surface sewer projects under construction in 2018–2020 including multiple cast in place concrete structures to divert flow from a CSO to the Dig Indy tunnel through large diameter collection and consolidation sewers. Sewer installation includes trenchless technology and open cut excavations in multiple locations. The challenges of construction in an urban environment around numerous existing utilities while coordinating with other municipal projects will be discussed.
