This facility is a true regional treatment plant that serves the Lillington, Fuquay-Varina, Coats, Buies Creek, Erwin and Angier communities, resulting in the consolidation of 5 separate discharges into one.. The treatment train begins at the headworks, where the raw wastewater is screened to remove paper, plastic, rags and any other debris greater than 1/8 inch in diameter. The wastewater then flows to the grit removal system where heavy inorganic material such as sand is settled out and removed. The flow is then measured through a parshall flume and recorded on a 24 hour interval. The biological treatment occurs in one of two 3.75 million gallon oxidation ditches. Here organic and chemical compounds are reduced by microorganisms under aerobic conditions. Once reduced, this wastewater is routed to the anoxic tanks where nutrient bi-products from the aerobic treatment are further removed. When the biological treatment is complete, the wastewater flows to one of two 1.1 million gallon clarifiers. Here the activated sludge is allowed to settle to the bottom of the tank where it is pumped back to the treatment units to treat more raw waste. The clear water leaves the clarifiers and flows to four disk filters and three traveling bridge tertiary filters where fine solids are separated from the final effluent. After filtration, the treated effluent is disinfected with Ultra -Violet light. Finally, the effluent moves to the cascade aerator. This helps add oxygen to the water before it flows to the Cape Fear River. Performance North Harnett Regional treated 1.54 billion gallons with an average daily flow of 4.208 MGD. We achieved a 99% removal efficiency for BOD, 99% for TSS and 99.9% NH3 along with an 85% and 53% removal of Total Nitrogen and Total Phosphorous respectively. Notification This report will be available for public inspection at the Harnett County Public Utilities administration office during regular operating hours. Certification I cKn" enal of law that this report is complete and accurate to the best of my knowledge.

The original facility was constructed as part of a 42 million dollar bond referendum and was designed to address existing and future treatment needs of our ever growing population in the southern portion of the county. South Harnett opened on June 3, 2009 which allowed for the immediate closure of the smaller Cooper's Ranch WWTP which was rated at .400 MGD and also allowed for the closure of our Carolina Lakes WWTP. The South Regional Plant consists of a head works which serves as a preliminary treatment process where the influent stream is screened to remove paper and plastics etc. and also has grit removal that allows for debris such as sand, rocks and coffee grounds to be settled and removed. Once the preliminary treatment is complete, the raw influent is conveyed to one of six ICEAS reactors (Intermittent Cycle Extended Aeration System). Here the wastewater enters a pre -react tank and immediately mixed with a concentrated mixture of microorganisms. The wastewater then enters the biological reactor where it goes through four 240 minute cycles per day of aeration/mixing/settling before the treated effluent is decanted and sent to traveling bridge filters for final polishing and light solids removal. After filtration the facility uses ultraviolet light to disinfect any remaining bacteria or pathogens and then flows across a cascade aerator which enhances the dissolved oxygen content of the treated waste stream before being discharged into the Lower Little River. Harnett County completed an expansion to 15 mgd in late 2012 to accommodate the treatment of 100% of the wastewater Performance South Harnett Regional treated 1.791 billion gallons of wastewater during this time with and average daily flow of 4.906 MGD. We had 99% removal efficiency for BOD, TSS and NH3. Total Nitrogen removal efficiency was 82% and Total Phosphorous was 37%. South Harnett received two Notices of Deficiency during the past year for missing data. However, these were due to data entry errors that were corrected and revised monthly reports were submitted. Notification This report will be available for public inspection at the Harnett County Public Utilities administration office during regular operating hours. Certification I certwy under penalty of law that this report is complete and accurate to the best of my knowledge.

HRW's service area includes but is not limited to Erwin, Coats, Buies Creek and Campbell University in the northern portion of the county. These flows are tributary to North Harnett WWTP. Meanwhile our South Central and Southwest communities including Anderson Creek, Spout Springs, Carolina Lakes and the HWY 87 corridor are tributary to South Harnett Regional WWTP. Performance The Harnett Regional Water Collection System collected and conveyed 3.331 billion gallons of sanitary sewer to our two regional biological wastewater treatment plants. During the year, HRW received 5 Notices of Violation related to sanitary sewer overflows. The majority of which occurred in Coats NC due to heavy rains that resulted from Inflow and Infiltration in that portion of our system. Fortunately, HRW has recently been awarded a 10 million dollar grant to address our challenges in this area.
