SO MT REST CTR STP - Advanced Wastewater Treatment in Guilford Township, Pennsylvania

SO MT REST CTR STP (South Mountain Rest Center Sewage Treatment Plant) is located in Guilford Township, Franklin County, Pennsylvania, United States. The plant serves a small community of 1,401 residents, providing advanced treatment for municipal wastewater. The facility employs advanced treatment processes, which exceed the secondary treatment requirements typical for small plants under the U.S. Clean Water Act. With a designed capacity of 1,362.74 thousand gallons per day and a current discharge volume of 946.35 thousand gallons per day, the plant operates below its capacity, indicating room for future growth. The treated effluent is discharged into a local waterway that ultimately drains into the Potomac River basin and then to the Chesapeake Bay. The Chesapeake Bay is a large estuary of ecological significance, supporting diverse aquatic life and migratory species. The plant's advanced treatment helps reduce nutrient loading, contributing to the bay's restoration efforts.

The plant discharges into a tributary of the Potomac River, which flows into the Chesapeake Bay. The Chesapeake Bay is the largest estuary in the United States, supporting critical habitats for fish, crabs, and waterfowl. Nutrient pollution from wastewater is a key concern for the bay's health, and advanced treatment at this plant helps mitigate eutrophication risks.
