The Venice Dual Force Main: Ensuring Resiliency through Redundancy in a Historically Large Scale Micro-Tunneling Project

This paper presents resiliency through redundancy construction management considerations and techniques that were used in the Venice Dual Force Main project. The project’s intent is to construct a second force main sewer to operate in tandem with the existing force main sewer for the purpose of fulfilling the three key objectives, (1) The new force main will operate as a parallel system in conjunction with the existing 48” force main to meet the existing Peak wet weather Flow demands experienced at Venice Pumping Plant. (2) Add operational flexibility and reliability. (3) Allow isolation of either force main during low flow conditions to perform necessary cleaning and maintenance.
