A Proactive Approach to the Rehabilitation of an Aging Brick Sewer Infrastructure in Newark, New Jersey
The City of Newark, NJ is in the midst of a commendable program to preserve its historic brick sewer system. The City's extensive Brick Sewer System Evaluation Program began in 1990. CDM has been the City's consulting engineer since Phase III/IV of the Program, which began in 1997. To date, CDM has overseen the evaluation of more than 149,000 linear feet of combined brick sewers and the structural rehabilitation of approximately 86,500 linear feet with cured-in-place pipe (CIPP). This sewer rehabilitation work has been conducted through seventeen different construction contracts over the past six years. The City and CDM are presently working on Phase VI of the Program which includes the re-evaluation of sewers inspected previously (approximately 124,000 linear feet) and anticipates the rehabilitation of 24,000 linear feet. Throughout the Program, the City has had the goal of making the rehabilitation as complete and long-lasting as possible. With this goal in mind, the Program has included particular attention to details such as intermediate manhole rehabilitation and sealed connection points between laterals and the lined sewer. Other sound practices include frequent communication with affected residents and business owners, isolating work areas to the extent possible, minimizing road closures, and utilizing temporary bypass pumping. These have also been employed to ensure a sound finished product with minimal disruption to the City. Most of the brick sewers rehabilitated have been egg-shaped and all have been greater than 20 inches in size. Various aspects of the construction process have been refined during the course of the Program. These items include procedures for the verification of sewer sizes and lengths by the contractor and the tube manufacturer prior to fabrication, lateral logging and accounting for each active and inactive connection, stabilization of void areas in the brick sewer prior to lining, and the development and documentation of required pre-lining and post-lining work.
