Gas and Oil Separator Application

Download the Application (PDF)


The Massachusetts Uniform State Plumbing Code, 248 CMR § 10.00, and the Massachusetts Water Resources Authority (MWRA) Sewer Use Regulations, 360 CMR 10.016, require that the MWRA be notified of the installation of a new gas/oil separator in the MWRA Sewer District so that it may be inspected and approved prior to backfilling. The separator installation is subject to approval by both the municipal plumbing inspector and the MWRA.

Please fill out (type written) the information in the application linked above and submit this form to MWRA. Upon submission of this form and a plan of the proposed gas/oil separator, MWRA will contact you to establish a time and date for inspection of the separator.

Please submit information at least 15 days before installation to insure that an inspection can be scheduled.
