Sewer Inspection and Cleaning Notice

Starting Friday, August 29, 2025, National Water Main Cleaning Co. will be cleaning and inspecting portions of the sewer mains located in basin 1 of the collections system (area around N. Linden Ln.). We expect to complete all inspections no later than September 8, 2025.

The clean and TV process helps identify sewer conditions such as leaks, breaks, and any other issues. If during this process you experience any sewer issues either notify the on-site crew or call the Sewer Department at 973-543-7030.
