Work is resuming this week in Ridgefield on the Water Pollution Control Authority's Wastewater Facilities Upgrade project. Force main pipe installation will continue along Ligi's Way, working from South Street towards Farmingville Road in the southbound lane.  The road is closed from 7am to 4pm.  More than 13-thousand linear feet of new 8-inch diameter underground force main piping is being installed from the Route 7 pump station to the South Street Wastewater Treatment Facility. The existing Route 7 Pump Station will be demolished and replaced with a new pump station in the same location on Route 7.  The Route 7 Wastewater Treatment Facility will be decommissioned and demolished.  The work is expected to last through August of next year.
