Project Description: The Lower North Branch Capacity Upgrade Phase 1 (CC Lower) consists of upsizing approximately 9,500 linear feet of existing 15-inch gravity sewer to 36-inch gravity sewer. The project limits will begin at 28551MH and will terminate at 25844MH.  The project limits and recommended sizing of the gravity sewer line were determined by the CITY and Hazen and Sawyer’s system hydraulic modeling study (Hazen and Sawyer, 2014), 2018 Collection System Master Plan, and ongoing 2020 Major Wastewater Collection and Transmission System (WCTS) Master Plan Updates.
