EASTHAM — A new road is being cut into the forest behind the Cape Cod National Seashore Visitors Center. It will lead to a third well house and second water tower — both elements of the final two phases of the town’s 10-year municipal water project.

By 2024, all 6,100 roads in Eastham are expected to have water mains, and every resident will have the option of hooking up to the water service. The $130-million project is in year eight of a 10-year timeline, said Town Administrator Jacqui Beebe.

It took Eastham town meeting voters 14 years to approve the project, Beebe said.

The road runs through forest owned by the town of Eastham and the National Seashore.

Together, the well house, tower, and roadway will disrupt 3.4 acres of forest. In exchange for that, the town agreed to put 21.3 acres of buildable town land into a permanent conservation restriction, Beebe said. The town negotiated that exchange with the state Dept. of Environmental Protection as mitigation for disrupting the habitat of the threatened spadefoot toad, Beebe said.

Aside from the well and tower, the last piece of the water project involves laying water lines from Nauset Regional High School on Cable Road to Doane Road and Ocean View Drive.

The first tower cost $2.5 million to build and is located by the sand pit on the north side of Nauset Road. The completed wells are near the sand pit and at Nauset Regional High School, Beebe said. The three wells will provide redundancy, and the towers are for water storage. —K.C. Myers
