Current Water System Status

Please be advised that as of December 1, 2023 the Pennsylvania Department of Environmental Protection on behalf of Governor Josh Shapiro has added Westmoreland County to the Pennsylvania county drought watch list. The drought watch declarations are in response to continued long term precipitation deficits and lack of recovery in groundwater wells.
During a drought watch, all water customers are asked to reduce water used by 5 percent through voluntary conservation measures.

The Municipal Authority

Welcome to the official web site for the Municipal Authority of the Borough of Derry in Derry, Pennsylvania. The Authority currently provides water service to approximately 2,500 customers in Derry Borough and Derry Township.

In 1952, the Authority purchased the water system serving the Borough of Derry and adjacent areas of Derry Township, from the Municipal Authority of Westmoreland County. The water system consists of a 1.25 MGD water treatment plant which treats surface water collected in the Upper and Lower McGee Run water dams located on Derry Ridge. The water is then piped to Ethel Springs Lake. The water treatment plant processes the water from Ethel Springs Lake under Permit No. 5650049. The current production is an average of 600,000 gallons per day.

In January 2011, the Authority purchased the Derry Borough sewer system from Derry Borough. The system consists of a wastewater treatment plant which has an average design capacity of .654 million gallons per day (MGD) and a maximum capacity of 1.6 MGD and wastewater collection system.
