Project Type: Gravity Sewer
Project Phase: Design & Permit
Project Description:
This project proposes the replacement of sanitary sewer piping to upsize the existing pipe from Manhole 01714MH to Manhole 01488MH for a distance of approximately 2,700 linear feet of 18-inch gravity sewer (this portion of the project was originally identified as SS7471). This project also proposes the replacement of sanitary sewer piping to upsize approximately 6,000 LF of existing pipe from Manhole 01488MH to Manhole 01463MH from 18-inch to 30-inch and to upsize approximately 4,700 LF of existing pipe from Manhole 01463MH to Manhole 28551MH from 21-inch to 30-inch. 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.
