Sewer Certifications

If you need a sewer certification in connection with the sale of a property or the refinancing of a mortgage, contact the Authority office.  The Authority can only issue a certification for sewer billings starting in 2006.  The fee for this certification is $35.

To request a sewer certification, mail to the Norristown Municipal Waste Authority a sheet or the NMWA Request Form for Sewer Certification with the following information:

  • Company contact information
  • Property address
  • Parcel number of property
  • Current property owner
  • Date of settlement
  • Instructions for transmitting sewer certification
  • Return envelope or overnight delivery package, if necessary
  • Check for the appropriate fee made payable to NMWA

Any check that is not issued for the correct amount will be returned to the company and a sewer certificaiton will NOT be issued.

Validity date for the sewer certification will be stated on the form.  After the validity date you must contact the NMWA to receive an updated notification.  There is no additional charge for the first update, provided it is within 30 days from the validity date.  Thereafter, there will be another certification fee charged.


For past due and delinquent accounts prior to 2006, you must separately contact Portnoff Law Associates at 866-211-9466.  You may need to request a second certification.  There is an additional fee payable to Portnoff Law Associates for this second certification.
