Wastewater Facilities

PCWASA owns and operates two Wastewater Treatment Facilities to handle the waste stream of approximately 10,000 customers. The combined treatment capacity of these two facilities is 6 million gallons per day (6 MGD).

The Line Creek/Larry B. Turner Plant – Dedicated in memory of former PCWASA General Manager Larry B. Turner in 2009, the Line Creek Wastewater Treatment Facility is a conventional carousel activated sludge plant, with additional filtration and UV disinfection.

Treated wastewater from the Line Creek/Turner Plant is discharged to three places. First, the Authority has a seasonal discharge permit to release up to 700,000 gallons of treated effluent per day into Line Creek during the summer and up to 1.1 million gallons per day during the winter. A second option for the Authority is to discharge up to 900,000 gallons of treated effluent per day into Flat Creek at the old Flat Creek Wastewater Treatment Plant outfall. This treated wastewater discharge helps to preserve the wetlands downstream from Flat Creek, since the Flat Creek Facility was taken off line in 2003. Finally, the third method entails transferring treated wastewater from the Line Creek/Turner Facility into a holding pond for eventual reuse via spray irrigation of up to 1.1 million gallons per day at the 18-hole championship golf course at Planterra Ridge Golf Club.

The biosolids at the Line Creek/Turner Water Reclamation Facility are processed through a filter belf press to form a sludge cake that is approximately 15% dry.  The solids then are taken to the landfill for disposal.

The Rockaway Plant – The PCWASA Rockaway Plant is located adjacent to the Authority’s Headquarters off of Highway 74 in Peachtree City. Rockaway is a sequence batch reactor (SBR) plant.

The Authority is permitted to discharge all of its treated wastewater from the Rockaway Plant (4 million gallons per day capacity) into Line Creek. However, treated wastewater from the Rockaway Plant also has potential reuse as non-potable water for irrigation. Currently, treated wastewater from the Rockaway Plant can be used for spray irrigation at the baseball fields located near the plant off of Highway 74.

The Rockaway Plant is a more technologically advanced plant than the Line Creek/Turner Facility. Rockaway operates with the help of a programmable login controller, which is a large mainframe computer that allows plant operators to check basin levels, activate times for pumps to run, and hear alarms if some part of plant is not working properly.

In addition, the Authority’s SCADA (supervisory control and data acquisition) system is housed at the Rockaway Plant, which allows operators at this facility to not only monitor the wastewater treatment process there, but also at the Line Creek/Turner Facility and the PCWASA collection/conveyance system as well.
