Warwick Township Water & Sewer Authority (WTWSA) provides for the collection, conveyance, and treatment of wastewater in Warwick Township, Bucks County, Pennsylvania. WTWSA owns and operates two wastewater treatment plants (WWTPs): Country Crossing WWTP, and Fish Creek WWTP.
Sewage flows within the northwestern portion of Warwick Township are treated at the Fish Creek WWTP. Fish Creek WWTP was put into operation in late 1985 and had an initial hydraulic capacity of 0.6 million gallons per day (mgd). The plant was expanded to a capacity of 0.85 mgd in August 1998. There have been several subsequent upgrades to the treatment facility to accommodate increasing regulatory demands.
The Fish Creek WWTP sanitary sewer collection and conveyance system, which is generally located in the northern half of Warwick Township, has been in operation for approximately 33 years and includes approximately 55 miles of PVC and ductile iron gravity sanitary sewer mains with precast concrete manholes. The collection system sewers have a minimum diameter of 8 inches, while the Fish Creek Interceptor, which ultimately leads to the Fish Creek WWTP, consists of 8-inch, 10-inch, 14-inch, and 18-inch pipes.
Sewage flows within the southwest corner of Warwick Township are treated at the Country Crossing WWTP, which began operating on January 1, 1998, and was designed to provide wastewater treatment for the Country Crossing residential subdivision and the Warwick Business Campus. The plant was originally designed to treat 0.12 million gallons per day (mgd); it was later upgraded to a treatment capacity of 0.32 mgd.
The collection and conveyance system for the Country Crossing area includes approximately 10.7 miles of PVC and ductile iron gravity sanitary sewer mains with precast concrete manholes. Additionally, there are approximately 2.6 miles of PVC force main. There are presently three pumping stations in the area tributary to the Country Crossing WWTP.
