The regularly-scheduled SEPTEMBER 27, 2021 public meeting of the Derry Township Municipal Authority Board will be conducted virtually using the “GoToMeeting” software.  The meeting will begin at 6:00 PM.

The meeting will be accessible to the public through computer or mobile device or dial-in telephone (audio only).  A copy of the meeting agenda can be found here.

Information on how the public may access the meeting can be found by clicking on the button below. 


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: January 1, 2021

DTMA Board recognizes that our customers may be experiencing financial hardship due to the impacts of COVID-19 on our daily lives. As the COVID-19 pandemic began to impact our local and regional community, the DTMA Board adopted Resolution 2020-26 in April 2020 to suspend penalties and collection procedures for past due customer accounts.

A notice was provided in the October 2020 billing statement indicating that penalties will be reinstated beginning January 1, 2021 on customer accounts that are not paid by the due date. Collection procedures, including late notices and other legal proceedings, will also be reinstated. To avoid incurring any additional fees or penalties, please bring all past due accounts current prior to January 1, 2021.

As the Covid-19 pandemic emergency continues to impact our lives, DTMA has taken steps to protect the health of our Employees and provide for the full and continuous operation of our wastewater treatment facilities to protect our water environment.

Recent directives from state and federal agencies have also directed us to limit interaction with the public at large. Consequently, please make note of the following Lobby and walk-in payment changes:

    • The DTMA Lobby will be closed to the public until further notice beginning on MONDAY, MARCH 23, 2020. As a result, DTMA Staff will not be accepting payments in person or receiving visitors during this time.
    • Customers are encouraged to mail in payments (along with the payment coupon) or use their bank’s bill payer system to remit payments. Credit card payments can be made via our automated system by calling 844-695-8672. Checking account payments can be made on our website or by calling Customer Service at (717) 566-3237 option 1. Please visit our website at www.DTMA.com for additional information.
    • Customers wishing to drop off payments in person may do so by using the locked drop box to the right of the outer office doors. Payment and appropriate payment coupon should be placed in the envelope provided. The customer’s name, service address, and account number should also be written on the envelope. For cash payments, no change can be provided; however, any overpayment will be credited to the Customer’s account. While great care will be used in handling any cash payments, we cannot be responsible for any lost or incorrectly recorded amount if the payment envelope is not sealed or does not contain the necessary information. Receipts will be mailed for all cash payments.
    • Account questions may be emailed to Customer Service at customerservice@dtma.com. Please expect at least two (2) business days for a response. If you wish to email any other Staff member, there is a Staff Directory on the DTMA website (www.DTMA.com).

We appreciate your understanding and thank you for your cooperation as we all work to navigate through this unprecedented and very serious situation.
