ANNUAL WASTEWATER REPORT
SEWER COLLECTION AND WASTEWATER TREATMENT FACILITIES
Report for FY 2021-2022
(July 1, 2021, through June 30, 2022)
On July 21, 1999, North Carolina Governor James Hunt signed a law, House Bill 1160, that placed reporting
requirements on the owners or operators of wastewater treatment and wastewater collection facilities in North
Carolina. Part of the legislation was a requirement to provide the user or customers of the system with an
annual report of the past year's performance including a summary of violations.
The purpose of these reports is to provide an understandable and informative description of the wastewater
treatment facilities and sewage collection system, describe the regulations with which these facilities must
comply, and promote a general awareness of these facilities and their role in protecting the environment.
The City of High Point operates two wastewater treatment facilities and a wastewater collection system that
collects and transports the wastewater to each of the two facilities. The names and permit information for
these facilities are listed below as well as those professionals designated by the State of North Carolina as
Operators in Responsible Charge (ORC):

NORTH CAROLI A'S INTERNATIONAL CITY'
SYSTEM OVERVIEW
The Public Services Department is responsible for operating and maintaining the wastewater collection and
treatment systems. The Divisions in the Department that are involved in wastewater collection and treatment
are: Water &Sewer Mains, Laboratory Services, Maintenance Services, Westside Wastewater Treatment Plant,
Eastside Wastewater Treatment Plant and Residuals Management.
The City's wastewater collection and wastewater treatment facilities provide service to homes, commercial
establishments, and industries. During this reporting period, there were approximately 41,744 connections
through which an average of 17.0 million gallons of wastewater traveled each day. This wastewater was
collected, treated, and then discharged back into the receiving stream. The city also treats wastewater from
the Archdale,Jamestown and Sedgefield communities.
Multiple government agencies assure that stringent standards are met before the treated wastewater can be
released into a receiving stream. These standards are listed in a National Pollutant Discharge Elimination System
(NPDES) permit. Each facility that releases treated wastewater into surface waters, a stream for example, must
possess one of these permits. These permits regulate the type and amounts of pollutants that a facility can
discharge. The discharge limits specified in these permits are based on the ability of the stream to withstand
the addition of pollutants without having any noticeable impact on the water quality of the stream. These
NPDES permits include monitoring requirements and discharge limits. Some vary with seasons and have
different maximums for daily values, weekly averages, monthly averages, and quarterly averages.
Wastewater treatment is a complex process that is often taken for granted. However, it requires expensive
equipment and skilled operations, maintenance, laboratory, solids handling and engineering personnel working
constantly to assure adequate treatment twenty-four hours per day, seven days per week, and 365 days
throughout the year.
COLLECTION SYSTEM OVERVIEW
The City of High Point wastewater collection system consists of approximately
677 miles of gravity wastewater lines; 17 miles of pressurized force mains; 23
wastewater lift stations, and 17,458 manholes. On average, 17.0 million gallons `>
per day (MGD) of wastewater flowed through this system from homes and
businesses, to either the Eastside or Westside Wastewater Treatment Plant
during the 2021-2022 reporting period. '
r;.
The collection system consists of both gravity lines and (pressurized) force �ii . ` woo'
mains. Wastewater discharged in neighborhoods flows by gravity into the �.►
collection system. The size of the collection system lines increases to handle the
higher flow as more and more wastewater is collected from outlying areas.
Once the gravity lines get too deep,the flow must be pumped or pushed up, by �--
the City's lift stations,to a higher elevation where use of the gravity lines will be
resumed. The largest of these collection lines route the wastewater to the two
wastewater treatment plants. "'� `

The lift stations are monitored 24 hours a day for proper operation. The Water/Sewer Mains Division has four
crews that are responsible for line cleaning and emergency response to calls from the public dealing with
collection system problems.

A State mandated fats, oils, and grease (FOG) program is also in effect. _
The Collection System maintenance crews work diligently to keep the
lines clean and well-maintained. A concerted effort is necessary a
between the city and its citizens to reduce the grease related problems �.q
in the collection system. Despite the City's best efforts, sanitary sewer r. Wry
overflows (SSO's) happen in High Point, just as they do in every I ,
municipality in North Carolina. An SSO is when wastewater escapes
from the wastewater collection system to the surrounding ground or
nearby surface waters. The North Carolina Division of Water _
Resources defines a reportable SSO as any spill to the ground more
than 1000 gallons or any spill, regardless of the amount,which reaches
any surface waters. During this reporting period,the City of High Point ,
had 21 reportable SSO's. Approximately 30% of SSO'sin the City were ; •t�-4 attributed to grease, 20%to Inflow and Infiltration, 11%to sewer main ' •
breaks or pump station failures, 23% to debris/other blockages, and .: _ , '.k •

EASTSIDE WASTEWATER TREATMENT PLANT
The Eastside Wastewater Treatment Plant (WWTP) is a 5-stage
- biological nutrient removal (BNR) facility and is currently
permitted to treat 26 million gallons per day (MGD). The BNR
-T` process is for phosphorus and nitrogen removal from
,r, p p g
wastewater.
1.1
-'/ • (Left)—Aerial view of Eastside WWTP
An environment is created using influent waste and return
sludge from the secondary clarifiers that encourages the
growth of phosphorus removing bacteria (PAO). The PAOs consume phosphorous at higher-than-normal levels
thus removing it before the water is discharged. In the BNR process, nitrogen is removed in two ways:Ammonia
is converted to nitrate nitrogen by an anaerobic biological process known as nitrification; Nitrate is converted
to nitrogen gas in a process called denitrification. These processes reduce the amount of total nitrogen in the
effluent. The reduction of phosphorous and nitrogen in the plant's effluent helps reduce the potential for algae
growth in Randleman Lake, to which the treated effluent is discharged.
Other treatment processes include screening, grit removal, primary clarification, 5-stage activated sludge,
secondary clarification, alum for additional phosphorus precipitation, effluent filtration, ultraviolet (UV)
disinfection, Dissolved Air Floatation (DAF) thickeners - to thicken sludge prior to dewatering, post aeration,
solids handling (dewatering and incineration), and odor control. All these processes support the biological
treatment necessary to remove pollutants from the wastewater.
The Eastside WWTP treated and discharged an average of 14.52 million gallons per day (MGD) or a total of
4,705.2 million gallons (MG) during the reporting year 2021-2022. During this report period,the Eastside WWTP
received one Notice of Violation (NOV) and two Notice of Deficiencies (NODs). The NOV was for exceedance of
total phosphorus for the month of January 2022. The two NODs were for: (1) Exceedance of total phosphorus
monthly limit (July 2021) and, (2) Failure in toxicity (April 2022).

RESIDUALS MANAGEMENT
The City's Residuals Management Division has the task of disposing of the wastewater biosolids from the
Eastside Wastewater Treatment Plant, the Westside Wastewater Treatment Plant, and the disposal of alum
sludge solids generated by the Ward Water Plant. In 2021-2022 Residuals Management processed 56.6
million gallons (MG) of sludge from the two
I .r I wastewater plants. The Residual's
_ t .-, operators use two high-speed centrifuges

• Estimated $13.3M for Richland Creek Outfall-Aerial Replacement Project
• Estimated $5.4M for the Whites Mill Lift Station and LaSalle Siphon Upgrade
Customer Responsibilities
The leading cause of overflows is debris and grease blockages in the lines. While the collection system is
designed to handle and safely transport sanitary waste to our treatment plants, too much grease or non-
biodegradable material placed into the system can cause clogs and result in sanitary sewer overflows (SSOs).
Dumping any fats, oils or grease derived from animal and vegetable sources, including meats, nuts, cereals and
beans, down any drain —home or business—can cause a stoppage that forces raw, untreated waste to spill into
our yards, streets, and streams. It is very important to help prevent all foreign materials, such as grease and
other household debris from entering the collection system, as these can cause blockages.
You can help the City of High Point reduce the number of overflows by
\ following these simple steps:
4 • Collect grease, fats, and oils from cooking in a container and dispose of it
4 in the garbage instead of pouring it down the drain.
■ Always scrape silverware, cookware, and dishes prior to washing.
441, • Place food scraps in the garbage for disposal with your household solid
waste.
• Remember "Wipes Clog Pipes" —so-called "Flushable Wipes" are NOT
FLUSHABLE. Sanitizing wipes should be disposed of in the garbage for
'°- 4"111. disposal with your household solid waste.
Y. e i r
