The City of Burlington's ("City") inverted sewer siphon that crosses the Winooski River broke during the July flood events that occurred throughout the state of Vermont. To mitigate the continuous discharge of raw sewage in the Winooski River, the City hired an on-call contractor to install a temporary forcemain to pump the sewage from the start of the sewer siphon, near the end of Plattsburgh Ave, to the North Wastewater Treatment Plant (North WWTP) located at the end of North Avenue at 3080 North Avenue. The City's contractor installed approximately 4,800LF of 12-inch diameter fused HDPE pipe, above ground to act as the temporary bypass piping for the broken inverted sewer siphon. The pipe runs above ground, with the exception of driveway crossings, where the pipe was trenched across the driveways to allow full time access to the affected properties and ultimately discharged into an above ground precast vault located at North WWTP. This precast vault was used to decrease the velocity of the sewage from the forcemain to protect the existing infrastructure located at the North WWTP. Approximately 1,000 LF of the pipe runs over the private property located at the River's Edge Condominium Association (Association), using a temporary easement with the City and the Association. The temporary bypass forcemain was taken out of service in November 2023 following a successful temporary repair to the inverted river siphon.
