We have some exciting news to share with our utility billing customers! Over the past few months we have noted on our invoices that we were converting to a new billing system. The conversion is now complete and will be effective AUGUST 19, 2022. The Muni-Link Utility Billing software will have new features to allow for a more user-friendly experience. Our new electronic billing and payment service through InvoiceCloud also has more features than before giving you more convenient options to view and pay your utility bill.

Monthly sewer bills will now be generated in-house again at the DTMA office. The first bill with the new software will be the September invoice. As part of the conversion to the new software, we have assigned new account numbers. If you have your account number stored in your bank’s bill pay system, you will want to update the account number. Access to your account on the new system and the link for online payments will be effective AUGUST 19, 2022. The link to access our new system is https://dtma.authoritypay.com.

Customers will be encouraged to create a login for their account to take advantage of many new features such as the ability to:

• Access current and previous bills
• Enroll in E-Bill to get invoices electronically through email
• Sign up for email and text notifications for account activity
• Pay invoices online 24/7 using E-checks, credit cards, or PayPal
• Pay by Text – sign up to get text notifications about your bill and have the option to pay through Text
• Schedule recurring payments through their bank or with a credit card
• Enroll in Auto-Pay

To create a login, you will need your new account number and the CID number that will appear on your September invoice and a valid Email address. If you are registering after August 19th but prior to your receiving your September bill, please contact Customer Service at (717) 566-3237 Option 1 to obtain your new Account Number and CID Number.

Landlords can continue to have their tenants receive a copy of the monthly invoice. The tenant’s copy of the invoice will have a unique CID number so the tenant will be able to create a separate login for the account where they can view and pay the invoice online or schedule recurring payments.

As we roll out the new system, additional information will be available on the website as well as on the monthly statements. While we have tried to make this conversion as seamless as possible, there may be a few things that need to be tweaked. We appreciate your patience during this conversion!

Please check out the new customer portal and let us know what you think! If you have questions or need additional assistance, please reach out to our Customer Service team at (717) 566-3237 option 1.


As we continue to perform our essential critical infrastructure function of treating millions of gallons of sewage daily, there are reports of unanticipated issues resulting from the shelter in place orders and perceived shortage of toilet paper.

Customers may be inclined to use a variety of substitute materials such as paper towels, baby wipes, or "flushable" wipes.  Despite misleading labeling, flushable wipes should never be flushed and absolutely none of the imaginative variety of alternative materials should be flushed down the toilet.

While flushable wipes and any paper products other than toilet paper are problematic for DTMA, our real concern is for our customers and homeowners.  Flushing anything other than toilet paper has the real potential to cause a blockage in your sewer lateral.  When a lateral blockage does occur, the best case for a homeowner is a several hundred dollar plumber’s bill to unblock your lateral, while the worst case for a homeowner is several thousand dollars of damage and irreplaceable losses from a flooded basement caused by the back-up from a blocked lateral.

Please remember the 3 "P’s when you flush the toilet.  Only pee, poop, and [toilet] paper should be flushed down the toilet.  It’s not worth the chance of a blocked lateral.  Please dispose of all "substitute" materials including anything labeled as "flushable wipes" in the trash!

Stay calm, stay home, and stay safe!


UPDATE:  November 11, 2021



After careful review of the proposed 2023 Fiscal Year Budget, the Authority has approved a moderate user rate increase of 2%. The rate increase will help to offset inflationary increases in operation, maintenance, and administrative costs associated with the collection, conveyance, and treatment of more than 1.5 billion gallons of sewage and the processing of 5,000 tons of sewage sludge or biosolids annually. The rate increase will also help fund sustainable capital improvement projects in order to maintain the level of service provided to our ratepayers.
