Monthly Operating Reports



All public water systems that treat their water using chemicals must submit a Monthly Operating Report (MOR) to the Drinking Water Program.

There are essentially two types of MORs submitted to the DWP:

  • The Small System Chlorination Report Form, as its name implies, is for small public water systems only. Systems in this category include trailer parks, restaurants, motels, and campgrounds. This report is designated as MOR-012.

  • All other MORs are designated MOR-001 thru -011. The DWP will accept electronic submittal of MORs-001 thru -011 in the XLS format and submitted via the designated MOR email address: DWPMOR@maine.gov.

Please note: All MORs must be submitted by the 10th of the month following the reported calendar month. (For example, operations in January must be reported to the DWP by February 10.)

MOR forms can be downloaded using links in the table below. MOR forms are available in two formats, XLS (MS Excel file) and PDF.


Procedure for Electronic Submittal of MORs:

  1. Using the Excel version of the MOR, fill in all appropriate fields.
  2. After you have filled out the MOR, print out a hard copy, sign it, and place it in your files. The hard copy of the MORs should be available for review by DWP inspectors during a sanitary survey.
  3. Each MOR should be saved with a file name with the following format: ABC Water District PWSID# [MEXXXXXXX] July MOR.xls (or ...MOR001.xls)
  4. Attach the file to an e-mail and send it to DWPMOR@maine.gov. The subject line of your e-mail should read: "ABC Water District PWSID# [MEXXXXXXX] July MOR".
  5. Upon receipt of an e-mail the DWP will send an automatic confirmation reply.
  6. Do not send additional copies via regular mail (USPS) or fax to the DWP unless requested.
