Troy Borough Sewer
DESCRIPTION OF THE WASTEWATER SYSTEM
Troy Borough’s collection system consists of a combination of 4-inch, 6-inch and 10-inch gravity sewers. In 2001
Constructed in 1988, Troy Borough’s WWTP is an activated sludge oxidation ditch that discharges to Sugar Creek under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Pennsylvania Department of Environmental Protection. The WWTP processes consist of grit removal, raw sewage pumping, an activated sludge oxidation ditch, final settling and chlorination. Waste sludge is discharged from the secondary clarifiers to two aerobic sludge holding tanks. These tanks are periodically decanted with the supernatant being returned to the head of the treatment plant where it is mixed with incoming raw sewage and re-processed.
The WWTP is permitted for an annual average hydraulic capacity of 0.400 MGD and a maximum monthly hydraulic capacity of 0.491 MGD. The WWTP’s permitted organic loading is 910 pounds of BOD per day.
Sewer Use Ordinance
The sewer use ordinance prohibits the discharge of water from downspouts and basement drains into the boroughs system. This ordinance also requires industries to obtain a permit from the borough prior to their connection to the WWTP.
