Winston-Salem Journal:October 5,2021 Winston-Salem/Forsyth County RECEIVED Utilit!Solides ut:T 14 2021 Water••Wastewater Waste NCDEQID WWNPDES Wastewater Collection &Treatment System—Performance Report for Fiscal Year 2020-2021 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 Winston-Salem/Forsyth County Utilities. It covers the period from July 1, 2020 through June 30, 2021.This report is published and released to our customers annually. Winston-Salem/Forsyth County Utilities (WSFC Utilities)operates two wastewater treatment plants (WWTPs) with a combined treatment capacity of 51 million gallons per day.The wastewater collection system includes approximately 1,783 miles of sewer lines,45 pumping stations, and one chemical odor control station. During the period covered by this report a total of 13.89 billion gallons of wastewater was collected and treated at these facilities. WSFC 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 5,784 dry tons of pelletized biosolids during FY 2020- 2021 which were beneficially applied to farmland.The water system has three additional NPDES permits, one associated with each water treatment plant. Swann Water Treatment Plant(WTP) operates under General Permit NCG590003,Thomas WTP under Permit NC0079821 and 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 1,836.27 dry tons of residuals were hauled from Neilson WTP and applied on farmland in Davidson County. A total of 271.85 dry tons were hauled from Swann WTP and applied on farmland in Forsyth County. 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 3.25.The bar chart in Appendix B shows the performance of the wastewater treatment plants during this period. Approximately 25,508 tons of regulated pollutants were removed by the treatment processes during the period ending June 30, 2021. 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. WSFC Utilities'goal is to have zero sanitary sewer overflows (SSO)from the wastewater collection system. However, during the last fiscal year, 74 events totaling 0.016%of the wastewater collected was spilled/overflowed from the sanitary sewer system.This is a combined total of 57 reportable and 17 non- reportable spills. Appendix A and D of this report list a detailed summary of plant and collection system overflows reported in FY 2020-2021. 1 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, FY 2020-2021 has resulted in one of the lowest reported SSO years (74)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 uses this same data to help develop future capital projects to alleviate the cause of repeat issues. We continue to send staff to Collection and Distribution System Schools to obtain the appropriate certification and training. WSFC 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 Cityworks. In order 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 recently upgraded preventative maintenance scheduler tool (FreeFlowH20) 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 keystrokes.This information also helps City Link convey issues to the customer in a timely manner. Major causes of SSO occurrences in FY 2020-2021 were attributed to grease deposits, debris accumulation and root intrusion. Because of this, funding was approved for FY 2020-2021 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 FY 2020-2021, WSFC Utilities cleaned more than 330 miles, which is 19%of the 1,783-mile gravity wastewater collection system. In-house personnel cleaned 124.6 miles of publicly owned/maintained sewer lines and contracted crews cleaned 205.5 miles at a cost of$1,351,129. Of the 330.1 miles that were cleaned, 69%or approximately 228 miles were proactively cleaned by in-house and contracted crews. For FY 2020-2021 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 following sewer backups to educate customers in those hot spot areas 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 FY 2020-2021, WSFC Utilities continued its proactive efforts toward the reduction of SSOs by spending more than $14 million on the rehabilitation of 38,640 feet of gravity sewer mains, 38 manholes, and 248 service laterals.The rehabilitated sewer mains primarily ranged in size from 6"to 42".The mains were rehabilitated by means of pipe bursting, cured-in-place lining of pipes,total replacement or a combination of these methods.The enhanced condition of rehabilitated sewer mains and manholes not only contributed to the reduction of SSOs, but also aided in the reduction of infiltration and inflow by decreasing and/or eliminating access points for storm water runoff and groundwater to enter the wastewater collection system. In addition, WSFC Utilities performed 2 CCTV inspection of 240,292 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. As always, customer involvement plays a large role in the reduction of SSOs. WSFC Utilities continues to promote its Can the Grease and No Wipes in Pipes campaigns to educate the public about the hazards of dumping fats, oils or grease (FOG) down drains and flushing wipes and other non-biodegradable products in the toilet.Annual presentations for City of Winston-Salem University, Habitat for Humanity, Neighborhood Academy and more were conducted online and always include our FOG and wipes information. Executive Orders and ongoing safety concerns limited our staff to a single public event in FY 2020-2021.The Juneteenth Festival on June 19, 2021 had an estimated attendance of 6,000 and our public information officer staffed a table in Biotech Place passing out FOG and wipes literature, as well as promotional items guests could win by engaging with our new prize wheel. It was extremely successful, and thousands of people learned about the hazards and costly messes caused by grease and wipes in their homes and our wastewater system. Pandemic shortages of toilet paper resulted in an increase in SSOs caused by wipes. In addition to other efforts to combat this, customers received a bill insert in July and August of 2020 with the No Wipes in Pipes flyer. In September 2020, our No Wipes in Pipes campaign won second place in the 2020 E Source Utility Ad Awards Contest. More than 500 submissions from throughout Canada and the United Sates were reviewed by an independent group of judges to recognizes creative excellence in utilities.The "bottom line" is you should only flush the Four Ps: Pee, Poop, Puke& (toilet) Paper. You can view our two campaign webpages at cityofws.org/nowipes and cityofws.org/grease. Social media posts, website news and news releases cross- promoted this information. We also updated our Good Neighbor Policy brochure and launched a new webpage at cityofws.org/gnp designed to educate the public and eliminate sewer backups in homes that would benefit from installation of a backwater valve device. 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 treated, thereby reducing overall operating costs.
