The Harbormaster's Department, in conjunction with a Massachusetts State Department of Marine Fisheries grant, provides and operates a shore-side pump out facility and a pump out boat. Wastewater is collected from boats and is disposed of into the Newburyport wastewater treatment plant. This program has pumped thousands of gallons of raw sewerage from vessels that normally would have been released into Newburyport 's waterways.
The shore side pump out facility located at the water's edge at Cashman Park and is operational 24 hours a days from Memorial Day to Columbus Day. The pump out boat is operational on Saturdays, Sundays and Holidays from 9:00AM to 5:00PM and Fridays from 1:00PM to 5:00PM and visits the various mooring areas and marina's in Newburyport weather permitting.
