Sewer Permits

A sewer permit is required when a building or property connects to the sanitary sewer or is temporarily or permanently disconnected from the sanitary sewer; when a sewer lateral is being altered, replaced, or repaired in the municipal right-of-way or easement; or when an addition, alteration, or change in use of a building or property will increase the anticipated daily volume of sewage. 

Applicants must notify the Sewer Department prior to beginning any work under an approved Sewer Permit and schedule an inspection with the Sewer Department for any sewer connections or disconnections, any work on a sewer lateral within the right-of-way or public easements, and any work that will affect the public sewer. Inspections will take place after the pipe is laid and connected, but before the pipe is covered. Any part of the work which may have been covered prior to inspection must be uncovered at the request of the Sewer Department’s representative. Applicants shall contact the Sewer Department at least one business day prior to needing an inspection. Appointments are on a first-come-first-served basis. Inspection appointments may be made for 8:00 AM, 9:00 AM, 10:00 AM, 11:00 AM, or 1:00 PM Monday through Friday.

Applicants must submit copies of any architectural or engineering drawings, plumbing schematics, floor plans, and/or other drawings created for the project. Applicants may use the space provided in the application to draw a sketch of the project if no other drawings were created or to supplement the drawing(s) submitted by the applicant. If the drawing(s) and/or sketch are not clear, legible, at an appropriate scale, and provide the information requested in the application, the application will be returned to the applicant.

See note 13 below for a list of activities that would trigger a sewer connection fee. If a connection fee is assessed, the fee must be paid prior to approval of the permit. Sewer Department staff will calculate the connection fee after reviewing the sewer permit application. Do not submit payment until a member of the Sewer Department has contacted you to confirm the amount due. The Sewer Department only accepts payment by check at this time. Connection fees are calculated and assessed in accordance with N.J.S.A. 40A:26A-11 et seq. and N.J.A.C. 7:14A-23.3.
