As of 1/10/25: The Authority is planning for sewer main rehabilitation using cured in-place pipe (CIPP), which is a process for trenchless rehabilitation and restoration of existing pipe. It is often utilized in preference to replacement of existing pipe, because it drastically reduces overall disturbance and costs compared to reconstruction. The objective is to eliminate infiltration of groundwater into the pipe network by sealing leaking joints and other imperfections. This, in turn, reduces the long-term costs of wastewater treatment through the reduction of extraneous flows into the collection and conveyance system.
