The District has several options when paying your sewer bill. You can go online at www.PayGASDMO.com or set your account up with an auto draft (ACH) from your checking account. We accept all major credit/debit cards which will include a 3% convenience fee. We can automatically charge your account on the 21st of each month. We also have a drop box at the Plant located next to the GASD Office door and the mailbox located at P Road and Harbour Road. We mail the sewer bills on the last day of the month and they are due on the 21st of the month. Late charges are assessed after that. If you need assistance with any of these options, feel free to call me at 573-372-0042.
