Pump Out

  • Pump-out boats are operated by the Town of Brookhaven for use by boaters in our waterways, at no charge. In order to contact the pump-out boats, you may use VHF CHANNEL 73 or simply wave them down as they patrol the local marina. These boats primarily function Friday through Sunday, as well as on holidays.
  • Self-serve stations can be found on the North Shore in Mount Sinai Harbor, located just East of Old Man’s Boat Yard, and in Port Jefferson Harbor, conveniently located at Danford’s Marina.
