HomeMy WebLinkAboutNC0023906_Annual Report_20220825MISSION STATEMENT "Protecting our Environment and Water Quality, through Teamwork and Excellent Service, now and for future generations." HOMINY CREEK WATER RECLAMATION FACILITY (WRF) The WRF is located in Wilson at 3100 Stantonsburg Road. It is a state-of-the-art regional treatment plant that processes wastewater for approximately 20,300 me- tered customers and a service population of approximately 52,000. The City of Wilson also treats wastewater from the Town of Black Creek, the Town of Lucama, the Town of Saratoga, and the Town of Sims. The term water redamation defines the treatment or processing of wastewater to make it reusable with specific treatment reliability. Reclaimed water must also comply with very stringent water quality criteria. The term water reuse defines the use of treated wastewater for beneficial uses, such as agricultural irrigation and industrial cooling. The City of Wilson is committed to reusing reclaimed water in areas that drinking water is not needed such as irrigation water for Wedgewood Golf Course, the Burt Gillette Athletic Complex and industrial process/cooling water. The reclaimed water system is part of the City's water conservation plan. Tfis report provides information concerning the City of Wilson's wastewater collection and treatment system performance for July 1, 2021 to June 30, 2022 as required in the North Carolina Clean Water Act of 1999 (House Bill 1160). lfyou have arty questions about the information contained in this report, or would like to leammore about ,o:,rwastewater collearon sifrerk or the Homy Creek Water Reclamatron Facility, please rail (152) 399-1492. TABLE DEFINITIONS & KEY <- less than > - greater than MGD (Million Gallons per Day) - a unit of measurement for flow volume. NTU (Nephelometric Turbidity Units) - a unit of measurement for Turbidity. The lower the value, the clearer the water. PPM (Parts per Million) - a unit of measurement. Parts per million compares to 1 minute in 2 years. PPB (Parts per Billion) - a unit of measurement. Parts per billion compares to 1 minute in 2,000 years. SU (Standard Units)- a unit of measurement for pH. Ammonia - one of several forms of nitrogen that exist in aquatic environments. Excessive ammonia can cause toxic effects to aquatic life. Ammonia is measured in PPM. BOD (Biochemical Oxygen Demand) - a required test that determines the amount of oxygen required by microorganisms to consume pollutants. BOD is measured in PPM. ChronicToxidty - a required test used to determine the potential effects of treated wastewater discharged into the receiving stream. The test ensures that treated wastewater discharged into surface waters does not negatively impact aquatic ecosystems. DO (Dissolved Oxygen) - a required test used to determine the amount of oxygen that is present in water. It is a direct indicator of an aquatic resource's ability to support aquatic life. DO is measured in PPM. FC (Fecal Coliform) - a required test used to determine the presence of disease causing organisms. FC are harmless but are used as indicators of other organisms (if FC are present others may be present). FC is measured as number of colonies per 100 milliliters of sample. pH - a required test used to determine the hydrogen ion concentration in water. It is used to indicate basicity or acidity of a solution on a scale of 0 to 14, with pH 7 being neutral. TN (Total Nitrogen) - a required test used to determine the sum of the different forms of nitrogen found in water, including nitrate, nitrite and ammonia. Nitrogen is a critical nutrient required for all life but elevated concentrations can result in excessive growth of algae and aquatic plants. TN is measured in PPM. TP (Total Phosphorus)- a required test used to determine all the different forms of phosphorus found in water. Phosphorus is a critical nutrient required for all life but elevated concentrations can result in excessive growth of algae and aquatic plants. TP is measured in PPM. TRC (Total Residual Chlorine) - a required test used to determine the total amount of remaining chlorine present in water. Chlorine is added to destroy or deactivate disease -producing microorganisms. Excess residual chlorine may cause adverse effects to aquatic life. TRC is measured in PPB. TSS (Total Suspended Solids) - a required test that measures the amount of suspended solids in a sample. TS5 are measured in PPM. Turbidity - a required test that measures clarity of water. It is used to indicate water quality and filtration effectiveness. Turbidity is measured in NTJ. NPDES PERMIT COMPLIANCE (NC0023906) The WRF was compliant with all NPDES permit limits this year.

These typically occur at manholes, pump stations, or broken sewer pipes. Infiltration/ inflow (l/1) is unwanted water that enters the sewer collection system through deteriorating older pipes, leaking manholes, or illegal connections such as roof drains, etc. During heavy rains, pipes can become overloaded from I/1 and cause S50s. Pipe stoppages caused by fats, ails, grease, debris, and non -flush - able items can also lead to 5S0s. Replacing and rehabilitating these lines and manholes reduces I/l into the sanitary sewer system, thus protecting the public health, improving treatment plant efficiency and reducing system mainte- nance. Generators provide emergency back-up power for pump stations and help prevent SSos. During fiscal year 2021-2022, the City of Wilson experienced sixteen (16) reportable 550s. The WRF treated 2.8 billion gallons of wastewater during this period.

HELP STOP THE CLOG! The majority of sewer backups and overflows caused by fats, oiis, and grease ?FOG) originate in residential areas. You can help prevent clogs by learning about FOG and how to dispose of it. By following three simple steps, you can make sure your pipes keep flowing properly: CAN IT! Once cooled, pour leftover oils and grease into a sturdy container, like an empty coffee can or glass jar and discard it in a trash can. SCRAPE IT! Before washing, scrape outfats, oils and grease residuals from pots, pans and dishes into the trash can. TRASH IT! Put fatty and greasy food scraps in the garbage, nct the drain.

Rural Water Association PROTECTING THE NEUSE RIVER The Lower Neuse River Basin Association, Inc. ?LNBA) and the Neuse River Compliance Association, Inc., (NRCA) are 501(c) (3) non-profit corporations comprised of municipalities and industries located in the Neuse River Basin. The mission of these organizations is to monitor and preserve the waters of the Neuse River and Neuse River estuary through innovative and cost-effective wastewater treatment and reduction strateg:es. The NRCA group is composed of 28 wastewater treatment facilities located in the Neuse River Basin. NRCA was issued North Carolina's first ba- sin -wide NPDES permit for nitrogen control January 1, 2003 and was reissued in 2008, 2013, and 2018. The group was given a mandate to reduce their Total Nitrogen discharge by 30%. Through the combined efforts of its entire membership, the NRCA exceeded the mandated 30% nitrogen reduction by removing over 55% of their nitrogen loading to the Neuse River estuary since 1995. The City of Wilson is proud to be a charter member of both the LNBA and NRCA. rn 0) S-12 rn 153 O.

When the wrong thing is flushed, results can include costly backups on your own property or problems in the Cty's sewer collection system and at the wastewater treatment plant. That's why it is so important to treat toilets properly and flush only your personal contributions to the City's wastewater system. "Disposable Does Not Mean Flushable" Flushing paper towels and other garbage down the toilet wastes water and can create sewer backups and sanitary sewer overflows (SS0s). The related costs associated with these SSOs can be passed on to ratepayers. Even if the label reads"flushable, you are still safer and more environmentally correct to place the item in a trashcan. "It's a Toilet, NOT a Trash Can" RIM 7U m C 7U m m The following is a partial list of items that should not be flushed: x Baby wipes, diapers x Cigarette butts x Egg shells, nutshells, coffee grounds x Food scraps x Oil x Grease x Tissues (nose tissues, all brands) x Sanitary napkins x Rags and towels x Cotton swabs, medicated wipes (all brands) x Syringes x Candy and other food wrappers x Rubber items such as latex gloves x Clothing labels x Cleaning sponges x Toys x Plastic items x Aquarium gravel or kitty litter x Hair it Underwear x Disposable toilet brushes x Medicines
