MASON FARM WASTEWATER TREATMENT PLANT
ORANGE WATER & SEWER AUTHORITY - CHAPEL HILL, NC
The Orange Water and Sewer Authority (O WASA) owns and operates the Mason Farm
Wastewater Treatment Plant located in Chapel Hill, North Carolina (NC). This facility serves
the Chapel Hill, Carrboro communities including the University of North Carolina at Chapel
Hill; all of which are located in southeastern Orange County. The plant discharge is regulated by
NPDES Permit NCO025241. The Class A land application program is regulated by Non -
Discharge (Permit No. W00021828) issued by the State of North Carolina Department of
Environmental Quality - Division of Water Resources.
This report documents that the biosolids generated during calendar year 2019 are in compliance
with 40 CFR Part 503 Federal Regulations, 15A NCAC 2T rules. All biosolids produced during
the 2019 calendar year were of Class A quality, therefore no Class B was land applied.
If there we any questions regarding this submittal, please contact me at your convenience.

Anaerobic Digestion Process
Summary Information Calendar Year 2019
The Mason Farm Wastewater Treatment Plant Anaerobic Digestion Process provides treatment for both
primary and waste activated sludges in a four -stage digestion process. The four anaerobic digestion tanks
provide approximately 1,800,000 gallons of digestion capacity and are operated in series. Normally the first
three anaerobic digesters are maintained in the thermophilic temperature range, in excess of 125e F and the
fourth anaerobic digester is operated in the mesophilic temperature range, less then 1150 Fahrenheit. For the
2019 calendar year, the average temperature and time for biosolids processed through the Class A
thermophilic process was 138.70 F and 24 hours. The digester operation -temperatures, recirculation and
mixing rates are monitored continuously; in addition to gas production. Process control testing (VA/ALK
ratios, pH and alkalinity, etc.) is checked routinely. Transfers into and out of the various digester tanks are
monitored and recorded.
The Mason Farm Wastewater Treatment Plant anaerobic digestion operating conditions have been carefully
monitored for the period of January 1, 2019 through December 31, 2019. The review confirms the following:
Average daily wastewater flow 7.6 MGD
Average daily dry tons biosolids recycled 3.8 Dry Tons
Average volatile solids reduction thru anaerobic digestion 54%
Average anaerobic (total) digestion time 48 Days
