How to Identify DTMA Employees

Please be alert when someone comes to your door asking for entry to your property. From time to time, individuals may pose as a utility worker to gain access.

Customers should verify the identification of all utility employees coming to their homes. DTMA employees drive distinctively marked vehicles with municipal license plates, wear uniforms and always carry a DTMA photo identification card.

Call (717) 566-3237 Ext. 303 when reporting suspicious activities involving DTMA employees or impersonators. Anyone fearing for their safety should call 911.


The Derry Township Municipal Authority was formed under the provisions of the Pennsylvania Municipal Authorities Act in 1971. The Authority purchased approximately 29 miles of collection facilities within the Township of Derry from the Hershey Sewerage Company in 1973. Installation of additional sewers during the 1973 project and ongoing Authority extensions and developer installed sewers has increase the collection system to the current size.

Today the Authority owns and operates two wastewater treatment facilities, fourteen wastewater pump stations, four meter stations, and more than 141 miles of sanitary sewers.  

The Clearwater Road Wastewater Treatment Facility with a capacity of 5.02 million gallons per day was placed into operation in 1977 and was expanded and upgraded in a project completed in 2005. The facility is located off Hersheypark Drive adjacent to the Swatara Creek. The Southwest Wastewater Treatment Facility with a capacity of 0.6 million gallons per day was brought on line in 1993. This facility is located off Swatara Creek Road in Londonderry Township.

The Derry Township Municipal Authority’s service area presently serves six municipalities and an approximate population of 20,000. The municipalities include the Township of Derry, and portions of Hummelstown Borough and the Townships of South Hanover, Lower Swatara, Londonderry, and Conewago.

Sewer FAQ
Who do I call when there is a sewage backup on my property?

Property owners are responsible for maintaining their sewer laterals and building sewers. If you experience a backup, please call DTMA. During normal business hours (Monday – Friday from 8:00 am to 4:30 pm) contact (717) 566-3237 Ext. 303.  For after hours and weekends call (717) 566-7928.

DTMA will need to assess the situation and will advise you accordingly.

What Causes a sanitary sewer backup?

Most sewer backups occur because the line is plugged with grease or roots or a combination of grease and roots.  Backups are also caused by a sag (or belly) in the line or a sewer lateral that has collapsed.  Never place anything in the system other than bathroom tissue.  Products like baby wipes and rags and other products labeled "flushable" frequently cause backups because they do not disperse like bathroom tissue.

What kinds of problems do fats, oils and grease (FOG) cause?

When fats, oils, and grease are introduced into the sewer, they are usually warm and free flowing.  However, shortly thereafter, they cool and harden and adhere to the pipe wall.  A FOG buildup will eventually cause a backup.

What is that strange pipe in my yard that looks like a mushroom?

That pipe is called a sewer cleanout.  The cleanout and its removable cap perform an important function by allowing an access point to your sewer line for cleaning and maintenance.

Make sure the sewer cleanout cap is in good shape and is on tight.  Missing or broken caps allow yard waste, litter and rain water to enter the sewer lines which can cause backups.

Can I connect a sump pump or roof drains to my sewer line?

No.  Connecting a sump pump or roof drains to your sewer line is prohibited because they direct excess water into the sanitary sewer line.  The extra water takes up capacity in the sewer lines and at the treatment facility and can cause sewer overflows.
