Sewer Collection System Activities
The City of Sanford's Distribution and Collection Division
performs routine and preventative maintenance on the collection
system daily and are on call for any problems with the system
twenty-four hours a day. This department consists of twelve
highly trained and certified employees.
Routine maintenance:
• Responded to 247 sewer backup or stop-
page investigations
• Jetted 36.68 miles of sewer main and
inspected collection lines.
• Staff mowed and inspected 41 miles of
sewer right-of-way; priority (aerial) lines are
inspected semi-annually at 122 miles this
year.
• Videoed 1.86 miles of line.
FOG Program
The City of Sanford's "Fats, Oils, and Grease Program" has
been in effect for thirteen years. The purpose of the
program is to prevent the accumulation of fats,
oils, and grease in the sanitary sewer system. 0 0 •
We have 182 commercial facilities with 193
grease traps participating in the program. Our • : •
FOG coordinator inspected 164 grease traps
this year and 1,019,927 gallons of grease -con -
taming fluids were removed through routine main-
tenance.
Sanford had one non -reportable spill this year due to grease.
YOU can help!
Please follow these guidelines:
• Collect cooled bacon grease or cooking oils in a
container and dispose of it in the garbage. Don't
pour remaining cooking oils, fat, or grease directly
down the drain.
• Place personal hygiene products and diapers in
a wastebasket. Do not flush plastics.
• Place food scraps in the trash or start a compost
area. Use the garbage disposal as little as possible.
• Don't pour hazardous materials, such as pesti-
cides, paint, and herbicides down the drain.
• Check before you dig! Do not plant trees,
shrubs, and other vegetation or erect fences and
other structures on or near sewer lines, ease-
ments, or manholes.
Sewer Improvements
The City rehabilitates manholes and sewer lines every year. In
addition, in depth analysis was performed to help identify areas of
the system in need of additional attention. As a result, work was
started that will decrease the impacts heavy rain events have on
our sewer system.

THE CITY OF SANFORD•S ANNUAL WASTEWATER TREATMENT AND COLLECTION SYSTEM REPORT
The City of Sanford is pleased to provide an overview detailing the operation, maintenance and performance of your municipal Water Reclamation Facility and Wastewater
Collection System. This report gives us the opportunity to keep you informed and to meet our state compliance requirements.
Big Buffalo Wastewater
Reclamation Facility
Treatment Process :.;00'—
Sanford's Big Buffastewater Reclamation Facility is
an advanced treatment facility with a permitted capacity of
12 ml er day. This past fiscal year we treated
1.2 billion gallons of wastewater. This is an
k9average of 3.2 million gallons a day. This facil-
ity treats waste from nineteen thousand res-
idential customers, schools and industries in
Sanford. Physical and biological processes at
the plant treat wastewater before it is released
into the environment.
The reclaimed water is treated by a Biological Nutrient
Removal process and safely disinfected further by Ultraviolet
Lights prior to being discharged through an outtall pipe into
the Deep River under the National Pollutant Discharge Elimi-
nation System permit (NPDES) number NC0024147.
StRiffng
Critical plant equipment is monitored twenty-four hours
a day by thirteen highly trained and certified employees at
the Big Buffalo WRF. Employees are certified by the State of
North Carolina for proficiency in plant operation, pump station
maintenance, laboratory analysis, land application of biosol-
ids, and pretreatment management. City employees are on
duty twenty-four hours, seven days per week monitoring all
system activity from the plant control room. The Big Buffalo
staff together has a combination of 168 years of experience.
Biosolids
The nutrient -rich organic materials resulting from the treat-
ment of domestic sewage at the Big Buffalo WRF are called
biosolids. Recycling theses biosolids is the most environmen-
tally friendly and cost-effective method for the City to manage
its biosolids. These solids are converted to a dense res,
removed, and reused on permitted land. The City's Land Ap-
plication program has 43 fields permitted for use, for a total
of 828.25 acres available for the application of biosolids. This
fiscal year we applied 1,364.4 dry tons or (8,672,600 gallons)
to 38 fields which equals 732.08 acres.
Reuse Program
Sanford's reuse program decreases the amount of nutrients
and flow discharged into the river. Treated wastewater in re-
cent years has been used to irrigate the local
municipal golf course. The City is also looking
into expanding its reclaimed water usage to e
industries in an effort to curb overall water
usage, free up more capacity in the river,
and to extend the life of the wastewater plant.
We have asked local industries to examine the
feasibility of introducing the use of reclaimed water into their
operations.
Pretreatment Program
Pretreatment programs help water reclamation facilities
maintain the requirements of water quality before it is re-
turned to the river basin. Big Buffalo WRF is designed to
handle domestic waste. Therefore, industries that
produce certain amounts of non domestic
waste are required to have a permit for dis-
posal. We currently have eleven industries —
in the pr. The City issues permits to I♦I
these industries specifying the parameters
of concern and flow limitations. Industrial
discharges are monitorddto specify the max-
imum amounts of pollutants that may be dis-
charged into the facility. Staff conducts routine monitRimand
inspections of these industries to ensure complian
Laboratory Analysis
Sanford's reclamation facility maintains a certified analyt-
ical laboratory approved by the State of North Carolina and
the EPA. Our lab is certified to perform environ-
mental analysis and report monitoring data to
- the Division of Water Quality for compliance
•; with NPDES effluent and pretreatment regu-
lations. Technicians observe wastewater dis-
charge at local industries in order to monitor
compliance, and laboratory personnel monitor
the effluent daily by testing twenty wastewater
parameters. All data reported this year was in compliance
with the NPDES permit.

Collection System Performance
Sanitary Sewer Overflow (SSO)
On a daily basis approximately 6 million gallons of waste-
water moves through the collection system from bathtubs, 1
showers, kitchen sinks, toilets, washing machines, and dish-
washers from homes and
businesses to the Big Buffalo
WRF.
Sanford has a wastewater
collet jp system with a to- to m
tal of approximately 219.517
miles of gravity wastewa-
ter lines and 25.853 miles
of pressurized force mains
ranging in diameter from
three inches to thirty-six inches. This system also encom-
passes thirteen sewer lift stations and 5,300 manholes.
Sanitary sewer overflows occur when wastewater escapes
from the sanitary sewer system to the ground.
Sanitary sewer overflow reasons
• Heavy rainfall accumulation
• Structural damage
• Pump station malfunction
' Vandalism
• Tree roots
• Grease
• Debris in lines
• Electrical failures
