  • ex. New Connection at 123 Main St, Sewer Availability at 34 Pine St

Project Address: Please fill in with the project address. A suggestions box should appear. You must choose the address from Suggestions… You will not be able to continue the application without a properly formatted address. Use the map on the right side of the page for reference.

If you are completing a New Connection permit application and the project address is outside of the District’s boundary, you will not be able to complete a New Connection application. If your property is not serviced by the Great Neck Water Pollution Control District’s collection system and you are still interested in applying for a New Connection permit, you will have to apply for a Sanitary Sewer Availability Study. A $250 non-refundable fee is associated with this application.
