Water Island is getting more water.

The small summer resort community on Fire Island, which officials said would be unable to battle a large fire if one occurred because of a lack of water mains, is getting more water.

Brookhaven Town on Thursday night adopted a $1.6 million bond resolution to finance the extension of a Suffolk County Water Authority main to the community.

The Water Island Fire Protection District will foot the costs of the 20-year bond, officials said.

“This is by far the best plan for fire protection for residents,” Town Councilman Neil Foley said after the board meeting.

The project, which hasn’t been given a start date, is part of a larger initiative between the Suffolk County Water Authority and Fire Island National Seashore to upgrade its wells.

Water Island hasn’t had enough water to fight fires since 2012 when superstorm Sandy damaged four wells and washed away two others.

The hamlet, between Davis Park and Fire Island Pines, has just 56 homes and lies within the boundaries of the national seashore.

Currently, the Fire Island Pines Fire Department would have to truck water from that community if a fire were to break out in Water Island, town officials have said.

Suzanne Johnson, president of the Water Island Association civic group signed off on the project.

“We’re just really looking forward to getting it started,” she told town board members.

Town officials on Thursday night said they scrapped original plans to replace the wells because residents feared the wells would one day wash away again.
