Project Progress! The team formed and poured concrete pipe saddles in this 25-foot-deep trench that will hold a 72-inch prestressed concrete cylinder pipe. This work is part of Wet Weather Pump Station project at @ALCOSAN which will provide an additional 120 MGD of flow capacity.

Yesterday, we broke ground on the Ohio River Tunnel, a 4.9 mile project that will capture excess wastewater during we weather events & reduce sewer overflows into our waterways. Proud to make this milestone with Steel City Tunnel Partners, a Brayman-Lane joint venture.
