Tharptown School Treatment System
Tharptown, Alabama

The Franklin County Board of Education is constructing new building additions to their existing Tharptown Junior High School. The school previously utilized a mound system for sewage treatment but due to capacity and site limitations, a new method of sewage treatment was necessary. The project consisted of the installation of a 25,000 gallon per day package wastewater treatment system, ultraviolet disinfection system, approximately 3,000 linear feet of force main, and a surface water discharge. The package wastewater system included two 25,000 gallon single wall fiberglass reinforced plastic primary treatment (septic) tanks and three 40,000 gallon single wall fiberglass reinforced plastic tanks with attached growth package recirculating media filter (PRMF) for treatment of domestic wastewater. The treated effluent has met the regulatory discharge permit limits of 10 mg/l BOD5, 10 mg/l TSS, 125 count/100 ml E Coli, and 1.5 mg/l Ammonia as Nitrogen since it was put into operation in January 2007.
