It covers the period from July 1, 2019 through June 30, 2020. 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 approximately 1,780 miles of sewer lines, 49 pumping stations, and one chemical odor control station. During the period covered by this report a total of 13.370 billion gallons of wastewater was collected and treated at these facilities. Utilities staff work 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 Archie Elledge WWTP under Permit WQ0029804. The biosolids dryer facility produced 7,122.63 dry tons of pelletized biosolids during FY2019-2020 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. All three water plant permits operated within compliance of their permit conditions during this performance period. The treatment process at the water treatment plants generates a Class -A residual that is land applied under Permit WQ0031314. During this compliance period, a total of 885.11 dry tons of residuals were hauled from the Neilson WTP and applied on farmland in Davidson County. A total of 479.14 wet tons were hauled from the Thomas WTP to Hanes Mill Road Landfill. Archie Elledge WWTP and the Biosolids Dryer Facility reported no violations of their permit limits during the reporting period. Muddy Creek WWTP had one permit violation 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 3.75. The bar chart in Appendix B shows the performance of the wastewater treatment plants during this period. Approximately 34,333 tons of regulated pollutants were removed by the treatment processes during the period ending June 30, 2020. The remainder of this document includes details about monitoring system discharges and overflows from our wastewater collection system and preventative maintenance programs established to prevent potential problems. Utilities' goal is to have zero sanitary sewer overflows (SSO) from the wastewater collection system. However, during the last fiscal year, 77 events totaling 0.00323% of the wastewater collected was spilled/overflowed from the sanitary sewer system. This is a combined total of 54 reportable and 23 non -reportable spills. Appendix A and D of this report lists a detailed summary of plant and collection system overflows reported in FY2019-2020. 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 Q. 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, FY2019-2020 has resulted in one of the lowest reported SSO years (77) 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 2019, Utilities staff attended the NC-AWWA-WEA Collections/Distribution System Schools where staff obtained three levels of certification in wastewater collections. Utilities is in the midst of a Collection System Improvement Program, which helps 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, we have also upgraded both of our CCTV camera systems to WinCan, 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, our field personnel can identify and submit information directly to the supervisor with a few key strokes. This information also helps CityLink convey issues to the customer in a timelier manner. The major causes of SSO occurrences in FY2019-2020 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 effort has reduced the occurrences of SSOs by preemptively targeting areas prone to the three major causes. In FY2019- 2020, Utilities cleaned more than 393 miles, which is 22% of the 1,780 mile gravity wastewater collection system. In-house personnel cleaned 693,580 linear feet of publicly owned/maintained sewer lines and contracted crews cleaned 1,383,360 linear feet at a cost of $1,175,467.50, with an increasing focus on our large diameter sewer mains. Of the 393 miles that were cleaned, 77% or approximately 303 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. During FY2019-2020, Utilities continued its proactive efforts toward the reduction of SSOs by spending over $11 million on the rehabilitation of 434,241 feet of gravity sewer mains, 143 manholes, and 125 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 access points for storm water runoff and groundwater to enter the wastewater collection system. In addition, Utilities performed closed circuit TV inspection of 710,218 linear feet of sewer mains. Staff and contractors also improved access to the collection system through inspection.and mowing/clearing of approximately 20 miles of easements. Winston-Salem/Forsyth County Utilities launched its "No Wipes in Pipes" campaign in April 2020. The campaign is an effort to encourage citizens to not flush wipes and other products in the toilet. The campaign includes social posts, English and Spanish fliers, and two informational videos. Several local broadcast news organizations ran news stories about the importance of protecting wastewater systems by not flushing wipes down the toilet. Lastly, staff continued to actively identify and plan for projects in an effort to reduce SSOs and infiltration and inflow into the wastewater collection system. In addition to the benefits of reducing SSO volume and the reduction of water getting into the system, these projects have the added benefit of decreasing the amount of wastewater 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 wastewater collection system free of materials that cause blockages by not dumping debris and fats, oils, or grease into the system.
