PLEASE PAY FROM INVOICE. THANK YOU Winston-Salem/Forsyth County Utilities Wastewater Collection and Treatment System Performance Report for FY2018-2019 This report is published in accordance with the requirements of the North Carolina Clean Water Act of 1999 and provides information on the Publicly Operated Treatment Works (POTW) and Collection System operated by Jul y periodfrom Winston-Salem/Forsyth County Utilities. It covers the 1, 2018 through June 30, 2019. This report is published and released to our customers annually. Winston-Salem/Forsyth County Utilities (Utilities) operates two wastewater treatment plants (WWTPs) with a combined treatment capacity of 51 million gallons per day. The wastewater collection system includes nearly 1,800 miles of sewer lines, 49 lift stations, and one chemical odor control station. During the period covered by this report, a total of 13.762 billion gallons of wastewater was collected and treated at our two treatment facilities. Utilities staff works hard to meet or exceed the requirements mandated by the North Carolina Clean Water Act and the requirements of the National Pollutant Discharge Elimination System (NPDES) permits that regulate the actual operation of the treatment plants,the disposal of our biosolids,and the operation and maintenance of our collection system. The wastewater collection system operates under NPDES permit WQCS00003. The Archie Elledge WWTP operates under NPDES Permit NC0037834 and the Muddy Creek WWTP operates under NPDES permit NC0050342. The treatment and disposal of residual biosolids produced by the plants is accomplished by anaerobic digestion followed by processing in a biosolids drying facility at the Elledge WWTP under Permit WQ0029804. The biosolids dryer facility produced 7,423 dry tons of pelletized biosolids during FY2018-2019, which were beneficially applied to farmland. The water system has three additional NPDES permits, one associated with each water treatment plant. The Swann Water Treatment Plant (WTP) operates under General Permit NCG590003, the Thomas WTP under NPDES Permit NC0079821 and the Neilson Plant under permit NC0086011. The treatment process at the water treatment plants generates a Class-A residual that is land applied under Permit WQ0031314. During this compliance period, the Neilson WTP produced 1115 dry tons of residuals that were beneficially applied to farmland. The Thomas WTP produced 479 wet tons of residuals that were disposed of in Hanes Mill Road Landfill. No residuals were disposed of at the Swarm WTP during this compliance period. Archie Elledge WWTP and the Biosolids Dryer Facility reported no violations of their permit limits during the reporting period. Muddy Creek WWTP had two permit violations as shown in Appendix A.The two wastewater treatment plants met the minimum requirements imposed by the State of North Carolina's Division of Water Resources by a safety factor of 3.86.The bar chart in Appendix B shows the performance of the wastewater treatment plants during this period. Approximately 37,320 tons of regulated pollutants were removed by the treatment processes during the period ending June 30, 2019. The remainder of this document includes details about overflows from our wastewater collection system and preventative maintenance programs established topreventpotential problems. . . Utilities' goal is to have zero sanitary sewer overflows (SSO) from the sewer collection system. However, during the last fiscal year, 70 events totaling 0.0007% of the wastewater collected was spilled/overflowed from the sanitary sewer system.Appendix A and D of this report lists a detailed summary of plant and collection system overflows reported in FY2018-2019. Since the passage of the North Carolina Clean Water Act in 1999 the total annual SSOs have been tracked against the baseline year of FY1998-1999 (Appendix C). Diligence by maintenance personnel toward preventative maintenance continued to be a major factor contributing to SSOs remaining at a lower level than that of the baseline year. In fact, FY2018-2019 has resulted in one of the lowest reported SSO years since reporting began in 1999. Our success in reducing SSOs also includes the incorporative use of Geographic Information Systems (GIS) with our computer maintenance management system, Cityworks. Together,GIS and Cityworks can display historical work order information which allows our crews to respond to areas where issues have repeatedly occurred. Management also uses this same data to help develop future capital projects to alleviate the cause of repeat issues. In 2018, Utilities staff attended the NC-AWWA-WEA Collections/Distribution System Schools where staff obtained six levels of certification in wastewater collection. Utilities is in the midst of a Collection System Improvement Program,which will help us prioritize and schedule our collection system preventative maintenance measures based on physical inspections from the field. Inspections ranging from routine cleaning to closed circuit television (CCTV) are tracked in the City of Winston-Salem's computerized maintenance management system; Cityworks. In an effort to collect more uniform data and to make crews more efficient, both of our CCTV camera systems continue to utilize Granite Net, which integrates with Cityworks. Essentially all of the information that we collect from the field is seamlessly entered into our preventative maintenance scheduler tool (COTools) and a decision making process is streamlined for cleaning,rehabilitation and/or replacement of our collection system infrastructure. By having these new systems in place, we help our field personnel bring information directly to the supervisor with a few key strokes. This information also helps CityLink convey issues to the customer in a more timely manner. The major causes of SSO occurrences in FY2018-2019 were attributed to root intrusion, grease deposits and debris accumulation. Because of this, additional funding was approved for FY2020 to provide for more preventative cleaning of the collection system. This will reduce the occurrences of SSOs by preemptively targeting areas prone to the three major causes of SSOs. In FY2018-2019, Utilities cleaned more than 429 miles, which is 24% of the 1,764 mile gravity sanitary sewer collection system. Of the 429 miles that were cleaned, 80% or approximately 344 miles were proactively cleaned by in-house and contracted crews. For FY2019-2020 the goal is to continue to increase the portion of proactive cleaning and to exceed our overall internal goal by cleaning 20% of the entire gravity collection system. In 2003 a Grease Interceptor Ordinance was adopted which regulates the operation and maintenance of residential, commercial and industrial grease trap interceptors. This ordinance alone has been effective in reducing the amount of grease related SSOs since its adoption. In 2003, the total number of SSOs spiked at 269;the following year that number dropped by nearly 30 SSOs and the count of SSOs has made a steady decline since that time. While this ordinance has been effective, further assistance from the public is necessary to completely solve this problem. Over the past year, in-house personnel have conducted outreach via community events and media opportunities in an effort to educate the public on the proper disposal of cooking grease, fats and other oils. In addition, maintenance personnel have been proactively cleaning the publicly maintained portions of sewer connections to keep sewer main lines clean and free of grease as well as tree roots and debris. This year, in-house personnel have cleaned 718,080 linear feet of publicly owned/maintained sewer lines and $1,042,560 was spent on contracted mainline cleaning which provided cleaning of nearly 1,547,515 linear feet of sewer lines, with an increasing focus on our large diameter sewer mains. Also, chemical root control contract is anticipated to treat approximately 190,000 linear feet of sewer main in the upcoming fiscal year. During FY2018-2019, Utilities continued its proactive efforts toward the reduction of SSOs by spending over$14 million on the rehabilitation of 39,426 feet of gravity sewer mains,48 manholes, and 160 service laterals. The sewer mains rehabilitated primarily ranged in size from 6" to 42". The mains were rehabilitated by means of pipe bursting, cured-in-place lining of pipes, total replacements, or a combination of any of these methods. The enhanced condition of these sewer mains and manholes provided by the rehabilitation projects not only contributed to the reduction of SSOs but also aided in the reduction of infiltration and inflow by reducing and/or eliminating sewer system access points for storm water runoff and groundwater. In addition, Utilities performed closed circuit TV inspection of 1,010,213 linear feet of sewer mains. Staff and contractors also improved access to the collection system through inspection and mowing/clearing of approximately 24 miles of easements. Lastly, staff continued to activelyidentify and plan for projects in an effort to reduce SSOs and L Y� infiltration and inflow into the sewer system. In addition to the benefits of reducing S SO volume and the reduction of water getting into the system, these projects have the added benefit of decreasing the amount of sewer to be treated,thereby reducing overall operating costs. As always, customer involvement will continue to be a factor in the reduction of SSOs. All customers can do their part in helping to keep the sewer system free of materials that cause blockages by not dumping debris and fats, oils, or grease into the system.
