Nantucket’s Sea Street Force Main

In 2018, the Town of Nantucket experienced a catastrophic failure of their 16-inch force main. After supporting the Town with emergency services, EP was retained to conduct an assessment of the failure. The study concluded that the existing force main should not be solely relied upon to convey all the wastewater flows to the Wastewater Treatment Facility without a backup pipe. EP designed and oversaw construction of a primary 20/24-inch sewer force main from the Sea Street Pump Station to the WWTF.

Construction began in December 2021 and paused this past June due to Nantucket’s construction moratorium during the summer months. Over the summer, EP assisted the Town with public outreach and communications to keep residents aware of the anticipated locations of construction which will resume this Fall and estimated to be complete in December 2024.
