Charlotte -Mecklenburg Utility Department (CMUD) collects wastewater from approximately 238,854
• and businesses throughout the county. Wastewater is collected and directed (via gravity flow
supported by sewage lift stations) to one of five CMUD wastewater treatment plants or the Rocky River
Regional Plant (owned and operated by the Water and Sewer Authority of Cabarrus County) where it is
treated. An average of 78.86 million gallons of wastewater is treated and discharged each day froni CMUD
plants. CMUD contributes an average of 3.40 million gallons a day (MGD) to theRocky'River Plant.
CMUD also treats roughly two million gallons for Union County.
More than 150 of CMUD's 761 employees work to maintain 4,170 miles of collection pipelines and 75
sewage lift stations throughout the county. The gravity sewer pipes in this system range in size from 8
inches in diameter to 78 inches in diameter.
Each of CMUD's wastewater treatment plants applies primary, secondary and advanced treatment to the
waste stream. Large solid particles and inorganic materials are removed by screening and settling. The
wastewater is treated biologically to remove dissolved pollutants. Disinfection reduces bacterial and
pathogenic materials. Finally, the waste stream passes through granular filters to remove very small
1

particles that may not have been removed through the settling process. The treated water is released to the
stream.
I. Primary Treatment
Solid particles & objects are captured by screens, grit chambers, and primary clarifiers.
2. Aeration/Secondary Treatment
Wastewater is aerated to support growth of microorganisms that remove hannful, pollutants.
3. Clarification
Solids and microorganisms settle out in large basins.
4. Advanced Treatment
Wastewater flows through granular filters to remove fine particles. Nutrient levels are reduced at
McDowell and McAlpine Creek Wastewater Treatment Plants.
5. Disinfection
Water is disinfected to remove any remaining pathogens, and the the treated water is released
into creeks.
11. Summary of Svstem Performance
tr#Twlm
CMUD successfully closed out the federal EPA Administrative Order. Additional information is available
on page 8.
We successfully collected and treated 99.9992 percent of the more than 28 billion gallons of wastewater the
community produced last year. There were 260 sanitary sewer overflows (SSOs) in our comniunity, a
decrease of 21 spills compared to the year before. This is the lowest number of spills since 2002 (259). In
fact, the number of spills per 100 miles of pipe continued to decline from 10.9 in 2007 to 6.2 spills in fiscal
year 2013 as illustrated by the table on page 3. An estimated 208,582.75 gallons spilled which is the lowest
since 1999.
Inspection crews and our customers find overflows. Reports of overflows where 1,000 or more gallons
reach surface waters are distributed to the media in an effort to notify the public. A legal notice is posted
when overflows of 15,000 gallons or more reach surface waters. Crews also use door hangers to notify
customers when appropriate.
IN

CMUD employees work 24 hours a day, 365 days per year, to prevent and respond to overflows.
Crews prevent overflows by clearing pipes of tree roots and grease, as well as replacing broken and aging
pipes. CMUD has increased its efforts to educate customers about properly disposing of fats, oils and
grease (FOG).
Performance Highlights
CMUD celebrated some importarit milestones even as it took numerous actions to prevent overflows and
protect water quality through effective wastewater treatment.
* Our wastewater treatment plants met 99.95 percent of all permitted discharge limits.
* All five wastewater treatment plants earned Peak Performance Awards from the National Association
of Clean Water Agencies (NACWA) for the calendar year ending 2012, NACWA Peak Performance
Awards recognize wastewater treatment professionals throughout the nation for protecting the
environment and public health through outstanding treatment and discharge regulatory compliance.
Mallard Creek Wastewater Treatment Plant earned a Platinum Award for a fourth year, which means
eight consecutive years of perfect compliance. McAlpine Creek Wastewater Treatment Plant was
awarded its first Platinum Award for five consecutive years of perfect compliance. Sugar Creek
Wastewater Treatment Plant, Irwin Creek Wastewater Treatment Plant, and McDowell Creek
Wastewater Treatment Plant earned Silver Awards for five or fewer violations in a one-year period.
0 8.88 miles of sewer pipe and 205 manholes were rehabilitated, repaired or replaced.
0 167.9 miles of sewer pipe were treated with root control chemicals.
* More than 998 miles of sewer lines were cleaned (including some multiple cleanings in the sarise
location) by CMUD Field Operations Staff and an additional 4.2 miles of pipe were cleaned by
contractors.
0 306 sewer service connections were replaced.
* More than 173 miles of rights of way were cleared by Field Operations and contractors to maintain
access to off-street sanitary sewer pipes and to help prevent root intrusions.
* CMUD continued to implement configuration and usability improvements for the Field Operations
deployment of the Work & Asset Management (WAM) Program's Azteca Cityworks system. All field
3

crews in the CMUD Field Operations Division continue to use Cityworks in the conduct of their day-
to-day maintenance, repair and overhaul activities across Mecklenburg County, The WAM team also
initiated the implementation of Cityworks for the Water Treatment and Environmental Management
Divisions and has compiled comprehensive asset registries for all water and wastewater treatment
plants. The WARM Team will pilot the system and processes for both divisions in Fall 2013 with
expected go -live in early 2014. The team will conduct classroom as well as one-on-one training and
mentoring for new Cityworks users and will deliver updated training to existing users as new
functionality is deployed.
With the GIS Foundation Project completed the GIS team is now focused on daily
maintenance of data and applications as well as continuing to refine the completeness and
accuracy of the data. Business processes have been established to assist in maintaining and
distributing data to users in the office and field. GIS is also integrated with other business
systems used by the department for daily operations.
CMUD expanded continuous improvement and optimization efforts utility wide in
FY2013. CMUD has increased performance levels using continuous improvement processes
and techniques coordinated at the department level and implemented at the division level.
Continuous improvement is used to achieve and maintain operational and economic
competitiveness and is coordinated with the Balanced Scorecard/Business Planning process.
These processes encourage and support operations and management of the Utility in
accordance with recognized best practice standards such as ISO, AWWA, NELAP, and
others as appropriate. Compliance with recognized standards are measured and confirmed by
the establishment and implementation of periodic and recurring audit procedures, along with
monitoring key performance indicators (KPI) and metrics. In 2007, Mallard Creek WRF was
the first City of Charlotte government facility to cam the prestigious ISO 14001:2004
certification. The ISO 14000 international certification program focuses on sustainable
optimized operations that first seek to minimize negative impacts on the environment. This
first initiative has helped to launch a refocused effort on instituting best practice standards
with ongoing audits to all CMUD operations. Corporate ISO 14001-2004 certification was
obtained in May 2010. This corporate certification currently covers Mallard Creek WRF,
McDowell Creek WWTP, the Biosolids program, and Sugar Creek WWTP. This
certification was recertified by external audit for FY201 3 . Obtaining and maintaining the
certification is a collaborative effort arriong many employees throughout CMUD. This
ongoing effort serves as a continuous improvement model for increased citywide efforts as
we move towards greater sustainability. Additional recent continuous improvement
approaches include obtaining certification through the National Environmental Laboratory
Accreditation Program (NELAP) for Lab Services in July 2012, with 2 sections of the
laboratory now fully certified, and 4 more sections working towards certification within the
next 24 months. CMUD is also participating in the AWWA Partnership for Safe Water
certification process for our water treatment facilities and distribution system, including Vest
WTP, Lee Duke's WTP, and the Distribution System at Phase 11 of four phases, and Franklin
WTP at Phase III certification, along with instituting reliability centered maintenance (RCM)
practices in our sewer collection service, and implementing new quality assurance metrics in
our customer service division.
CMUD continues to strive to be good stewards in all parts of operations, including fuel
consumption. In FY2012, CMUD completed a collaborative effort with UNC-Charlotte,
Centralina Council of Governments (CCOG), and Central Piedmont Community College
(CPCQ to assess the feasibility of using problematic fats, oil and grease (FOG) as biodiesel
feedstock. This feasibility study of alternative fuel was supported in part by grant funds from
the Biofuels Center of NC and the NC Green Fund, The study investigated brown grease use
as an alternative fuel product to determine if it will save on fuel costs, avoid disposal costs,
and reduce pollution for local governments. The economic analysis considered conventional
4

costs and total life cycle impact assessment. Final reporting, which indicated new potential
operational approaches for wastewater utilities, was submitted in FY2012. Presentation of the
results and the possibilities of identified sustainability practices, were given throughout the
state by members of the collaboration. Additionally, new study work on Fuel Analysis for
CMUD field operations, other City of Charlotte and UNC- Charlotte Alternative Fuels
Feasibility Study work, and several other energy management and air quality initiatives, such
as the installation of an electric vehicle charging station at one CMUD facility and the
purchase of an electric vehicle, are all steps in the evolution towards greater sustainability
within clean, efficient, cost effective utility operation. In FY2013, a citywide effort, in which
CMUD is strongly involved, was initiated as a result of the Alternative Fuels Study. This
effort is an exploration of a potential citywide RFP for infrastructure associated with
alternative fuels and technology for city fleet.
• There are 75 Wastewater Lift Stations serving portions of the CMUD service area. Staff performed
160 preventive maintenance tasks for a total of 3,012 work hours. This does not include twice weekly
station checks, wet well cleaning, emergency generator testing, or emergency/routine repairs. Turtle
Rock, Stewart's Crossing, Avensong, and Woodbury were removed from service due to the
installation of new gravity outfalls.
• Construction of the Briar Creek Relief Sewer Project (Phase Two) began in Spring 2012. The
project is 35% complete. Phase Three is being designed and will begin after Phase Two is
complete.
• Construction of the McAlpine Creek Relief Sewer Project (Phase Three) began in October
2012 and is 20% coinplete.
• Construction of the McAlpine Creek Wastewater Treatment Plant Design Build Project began. It will
add filters to improve reliability and provide redundancy. This project will not increase treatment
capacities or permits. This is the first CMUD Design Build Project.
0

• CMUD and the North Carolina Urban Water Consortium worked with UNC-Charlotte (UNC-C) staff
and students to create new educational materials, The students researched, created, and then presented
brochures, social media, and educational documents to CMUD and other utilities in May. UNC-C will
formally present to N.C. Urban Water Consortium in September. Some of the materials will be
implemented during fiscal year 2014.
• City staff inspected grease -handling facilities at 4,664 food service establishments and restaurants of
including follow-up inspections) to ensure proper grease disposal.
• The City continued its Grease Free education program to teach proper disposal of this pipe -blocking
menace. Inspectors mailed information to 3,250 customers near spill sites and handed out information
to 11,624 customers in apartments / multi -family complexes.
• Staff conducted presentations to more than 1,550 children and adults. Multiple Earth Day events also
provided opportunities to distribute Grease Free scrapers, pens and other items.
• CMUD continues to use door -hangers specifically for maintenance personnel or property managers of
apartment or multi -family complexes. This reinforces best management practices for prevention.
• Staff continues to provide bilingual door hangers and promotional items for property managers to give
to new residents.
• Bill insert in November mailed to 250,000 customer account holders each month. These also were
repurposed as messages on our web site, and extra inserts were used at events.

Continuing Challenges
Wastewater Collection Challenges
The greatest continuing wastewater challenge in this community — and in others across the U.S. — is sewage
overflows. Of the 260 sewer spills that occurred, for the first time since recording primary causes, grease
accounted for less than 50%. Grease has traditionally been the primary cause of 50-60% of spills. Other
spill causes included the infiltration of tree roots into pipes, broken pipes, debris, and vandalism.
Fiscal Year 2013 Overflows by Primary Cause
Grease and other blockages that lead to sewer over -flows are cleared by CMUD crews, using various
cleaning methods, including mechanical rudders and truck -mounted water jets. If damaged pipe or other
infrastructure is discovered it is repaired. The spilled sewage can sometimes be captured and pumped back
into the sewer system.
For the third straight year, CMUD successfully kept sewer in the pipe during large rain events. Large sewer
pipes and regular cleanings are keys to this success.
N

CMUD Rapid Response Crews are quick to respond when notified of a possible spill. Crews responded to
more than 90.4 percent of the spills within 60 minutes and more than 96.2 percent of the spills within 120
minutes. The state standard for response is 120 minutes or less.
U.S. Environmental Protection Agency (EPA) Administrative Order Update
Charlotte -Mecklenburg Utility Department (CMUD) performed a voluntary Management, Operation, and
Maintenance (MOM) Audit in 1999-2000 at the EPA's request. During 2003, frequent heavy rains
contributed to Charlotte's worst year of wastewater overflows. At that point the EPA and CMUD met
several times to review the audit and actions taken since 2000. CMUD also worked with North Carolina
Department of Environment and Natural Resources (NCDENR) to receive a state collection system permit.
In March 2007, the U.S. EPA issued a formal Administrative Order for Charlotte -Mecklenburg Utility
Department. This Administrative Order is a regulatory enforcement action that includes a scries of steps
CMUD must take to reduce overflows in our community. These steps included paying a civil penalty for
past spills and assuring that certain construction projects would be, completed on time.
Charlotte was the first major city in the Carolinas to face EPA enforcement as it relates to overflows. Quite
a few other communities in the southeast, including Atlanta, Mobile and Knoxville already received a
much more severe EPA enforcement action known as a judicial Consent Decree.
Preventing sewer spills has been a high priority in Charlotte -Mecklenburg for more, than a decade. The
administrative order helped further guide our ongoing efforts to address a community problem. We have
increased preventative line maintenance, capital improvements and other programs.
Comparing FY 2012 with FY 2013 SSOs, shows that CMUD has experienced a 7,5% decrease in total
annual SSOs. Since 2007, CMUD' s annual SSO count has reduced as follows:
FY 2007 419
FY 2008 362
FY 2009 358
FY 2010 349
FY 2011 335
FY2012 281
8

FY2013 260
The reduction in SSOs since the effective date of the Environmental Protection Agency
Administration Order is 158 SSOs annually, or a 37.9% decrease.
As of June 30, 2012, CMUD completed all requirements set forth by the EPA order.
The below graph demonstrates the reduction in monthly SSOs / 1.00 Miles of collection system and the
The City of Charlotte and Charlotte -Mecklenburg Utility Department is committed to the continuous
improvement of our Management, Operations, and Maintenance Programs, to prevent SSOs.
Wastewater Treatment Plant Challetkgoes
Charlotte -Mecklenburg Utility Department's five wastewater treatment plants met 99.95 percent of all
discharge limit tests set forth by our NPDES permits but our commitment is 100 percent compliance. Staff
continues to improve maintenance capabilities and overall perforniance. Major rehabilitation and
improvement projects help maintain compliance. Future upgrades and expansions are being added.
During this fiscal year there were three (3) permit limit violations out of a potential of 5,820 compliance
tests. These violations were for toxicity testing. The toxicity violations are very unusual and have raised
questions about potential sampling or testing errors that could have contributed to these failures. Please see
Section 1113 of this report for additional details of these violations.
There was one sanitary sewer overflow at a wastewater treatment plant. On June 9, 2013, the McAlpine
Creek Wastewater Treatment Plant had a valve that failed to close completely as rain diluted wastewater
was moving from Equalization Basin into the treatment process. An estimated 2,500 gallons overflowed.
Operators quickly stopped the spill. Aformal news release was emailed to media.
9

Discharge of wastewater that had not completed all of the treatment processes occurred twice. During these
events, the wastewater was treated with the exception of the final ultra -violet disinfection process.
Operators on -site quickly responded and took appropriate steps to repair equipment and restore treatment
process. No dead fish were found associated with this bypass.
CMUD Environmental Management Division operates the System Protection Section to help maintain our
infrastructure. System Protection consists of the Industrial Pretreatment Program and the Commercial
Source Program.
The Pretreatment Prograni identifies, permits, and regulates industrial Users and others to keep unsuitable
discharges out of the Publicly Owned Treatment Works (POTW). The Commercial Source Program
inspects and regulates Commercial Users, such as food service establishments, to keep unsuitable
discharges such as fats oils and grease out of the POTW.
While industrial and commercial compliance is extremely high in charlotte -Mecklenburg, identifying
sources of potentially harmful discharges is an ongoing challenge. In fiscal year 2013, the Trunkline
Monitoring and Grease Free progranis also continued, enabling CMUD's Systein Protection and Water
Quality staff to closely observe what industrial, institutional i and commercial customers discharge into the
POTW, identify potential problem areas, and protect the collection system, sewer line workers, treatment
plants and the Environment.
In 2007 a study of the McAlpine, Irwin and Sugar creek basins was completed to help identify our
community's future wastewater treatment capacity needs through the year 2030. Construction activity
resulting from the study includes extensive rehabilitation and upgrades to hwin Creek Wastewater
Treatment Plant. These activities will improve overall efficiency at the plant. Phase two will start in FY14.
At McAlpine Creek Wastewater Treatment Plant, the first CMUD Design Build Project started to add
filters. This will improve reliability and provide redundancy. These projects will not increase treatment
capacities or permits.
"MUD, Mount Holly, and Belmont entered into memorandums of understanding to create the partnership
needed for the regional wastewater plant. Based on these agreements, CMUD purchased about 180 acres
of land along with nutrient allocations from an existing industrial treatment plant. The agreements and
nutrient allocation purchase will facilitate maintaining compliance with the Lake Wylie nutrient TMDL
while planning and construction of the regional plant progresses. An Environmental Impact Statement is
being completed with N.C. DENR. Once the E.I.S. is successfully completed and the PDES permit is
obtained, wastewater capacity requirements will be monitored and construction timed and sequenced to
meet those needs.

Charlotte -Mecklenburg Utilities collects wastewater from an estimated 229,002 connections ection to household
d businesses throughout the county. Wastewater is collected and directed. (via gravity flow supported by
sewage lift stations) to one of Utilities five wastewater treatment plants or the Rocky River Regional Plant
where it is treated.. An average of 75.5 million gallons of wastewater is treated and discharged each day
from Utilities plants.
More than 150 employees yees work to maintain, 4,073 Wailes of collection pipelines and 79 sewage lift stations
throughout the county. The gravity sewer pipes in this system range in size from 8 inches in diameter to 78
inches in diameter.
Each of Utilities' wastewater treatment plants provides primary, secondary and advanced treatment to the
waste stream, Large solid particles and inorganic materials are removed by screening and settling. The
wastewater is treated biologically to remove dissolved pollutants, Disinfection reduces bacterial and
pathogenic materials. Finally, the waste stream passes through sand filters to remove very small particles
that may not have been removed through the settling process. The treated water is released to the stream.
i

How Your Wastewater is Treated
3
1. Primary Treatment
Solid particles & objects are captured in grit screens and primary clarifiers.
2. Aeration/Secondary Treatment
Wastewater is aerated to support growth of microorganisms that remove harmful pollutants.
3. Clarification
Solids and microorganisms settle; out in large basins.
4. Advanced Treatment
Wastewater flows through sand filters to remove lime particles.
5.+ Disinfection
Water is disinfected to remove any remaining pathogens, and then the'treated water is released back
into creeks to flow downstream.

Utilitie's is proceeding with the implementation of a Work and Asset Management ( %r M) Prograr
that includes deployment of Azteca Cityworks, as well as improved infrastructure management
processes. Functional deployment of Azteca Cityworks for Utilities Meld Operations Division will be
complete in fall 2011. Continuous improvement processes are in place and final testing of integration
to the advantage customer information and billing system are expected to be complete in early
September 2011. Field mobility devices (computers) have been acquired and are being configured for
use by all field crews. Improved asset management processes are being rolled out in tandem it the
system deployment.
Utilities contracted for physical survey of the entire wastewater ate collection system, including
inspection of manholes and any exposed piping. This is amulti-year project to collect data that will be
used as part of the foundation of a new geographic information system (G) and for Hydraulic
modeling that is needed for planning and implementation of the capacity_ assurance program, The data
being collected includes manhole locations, flowline elevations, pipe sizes, construction materials, and
other information. This survey is approximately 99% complete.
CUD expanded continuous improvement and optimization efforts utility wide this year. In 2007,
Mallard. Creek WRF was the first City of Charlotte government facility to earn the prestigious ISO
14001:2004 certification. The ISO 14000 international certification program focuses on sustainable
optimized operations that first seek to minimize negative impacts on the environment. This first
initiative has helped to lead a refocused effort on instituting hest practice standards with ongoing audits
to all operations. Corporate ISO 14001:2004 certification was obtained in May 2010. This corporate
certification currently covers Mallard Creek WRF, McDowell Creek WWTP, and the Biosolids
program. Obtaining the certification was a collaborative effort among many employees throughout
C'MUI . This ongoing effort serves as a continuous improvement model as we move 'towards greater
sustainability. Additional continuous improvement approaches include seeking certification through
the National Environmental Laboratory Accreditation Program (NELAP) for Lab Services,
participating in the AWWA Partnership for Safe Water, and instituting reliability centered maintenance
practices in our sewer service area.
* Utilities continues to collaborate with C,-Charlotte, C'entralina Council of Governments, and C PC;C"
to assess the feasibility of using problematic fats, oil and grease (FOG) as biodiesel feedstock. This
feasibility study of alternative fuel has been awarded grant ftmds from the Biofels Center of NC and
the NC~ Green Fund. The study is investigating brown greaseuse as an alternative fuel product to
determine if it will save on fuel costs, avoid disposal costs, and reduce pollution for local governments.
The economic analysis will consider conventional casts and total life cycle impact assessment. final
reporting is expected by the end. of FY2012.
Utilities reclaimed water program continues to operate. Reclaimed: water is highly treated wastewater
effluent that is land applied, rather than being discharged into the creek. The Traditions Golf Course e i

maintenance tasks for a total of 2301 work hours. This does not include twice weekly station checks,
wet well cleaning, emergency generator testing, ore rgencylroutine repairs.
Plott Road, Kingstree, White Forrest, Quay Road, and C'hristenbury lift stations were removed from
jservice due to construction of new gravity lines.
Phase one ofthe Briar Creek belief Sewer project was completed. Construction of phase two i
expected to begin fall 2011 or early2012a
Phase two of the McAlpine Creek Relief Sewer project was completed and in service on June 13, 2011.

excess mercury was stopped. Prior to this point Irwin Creek WWTP's average concentration of mercury
discharged was 10% of the permitted discharge.
Discharge of wastewater that had not completed all of the treatment processes occurred three times, On
each occasion, the wastewater was treated with the exception of the final disinfection process, These
bypasses can be caused by an electrical, mechanical, computer, or operator error. In each case, operators
on -site quickly responded to the bypass and took appropriate cleanup/repair action. No dead fish were
found associated with these bypasses.

There are five wastewater treatment facilities owned and operated by Charlotte -Mecklenburg
Utilities. Below is a list of these facilities and their applicable NPDES (National Pollutant

reduces bacterial and pathogenic materials. Finally, the waste stream passes through sand filters to
remove very small particles that may not have been removed through the settling process.

Treatment Plant earned a Silver Award for five or fewer violations ns in a cane -year
rite.
10.1 miles of sewer pipe and 722 manholes were rehabilitated, repaired or replaced.
249 miles of sewer pipe were treated with root control chemicals.

993 miles of sewer lines were cleaned (including some multiple cleanings in the saine
location) by Fuld Operations and-14.3 miles of pipe were cleaned by contractors.
More than seven miles of large diameter pipe Was also cleaned by contractors.
214 sewer service pipes were replaced.
380 cleanouts installed for customers that did not have them or had defective
cleanouts.
150 miles of rights of way were cleared by Field Operations and contractors to
maintain access to s ' `taty sewer pipes and to help prevent root intrusions.
After replacing, Mine hydraulic jetting I vacuum combination machines during the last
fiscal year, Utilities has further strengthened its collection system cleaning programs
by developing a hydraulic jetting nozzle standard operation procedure (SOP). Nozzle
sets, including nozzles for different applications, were purchased and assembled for
all thirteen combination machines in our fleet. We are optimistic that the increased
efficiency in cleaning will help prevent such S SOs as those that occurred this period
from occurring in the future.
Utilities is proceeding with the implementation of a Work and Asset et Management
(WA.I I)Program that includes deployment of Azteca Cityworks, as well as improved
infrastructure management processes. Development environments for the software
are currently operational and business process mapping workshops will be complete
by November 2d10. Utilities Field Operations Division will begin using the system
in the first quarter of calendar year 2011. This implementation includes management
components as well as field -deployed technology at the crew level.
Utilities has contracted for a physical survey of the entire wastewater collections
system, including inspection of manholes and any exposed piping. This multi -yeas
project is estimated to coast more than $ ,000,000. The project is collecting data that
will be used as part of the foundation of a new; geographic information system (CIIS)'
and for hydraulic modeling that is needed for planning and implementation of the
capacity assurance program discussed earlier. The data being collected includes
manhole locations, flowline elevations, pipe sues, construction materials, and other
information. This survey is approximately 95% complete.

certification currently covers Mallard Creek WRF, McDowell Greek WWTP, and the
Biosolids program. The ISO 14000 international certification program focuses on
sustainable optimized operations that first seek to minimize negative impacts on the
environment. Obtaining the certification was a collaborative effort among many
employees throughout Utilities led by Enviro rsental lvlanagement System
Protection. I In 2007, Mallard Creek WRF was the first City of Charlotte government
facility to earn this prestigious certification. This ongoing effort serves as a
continuous improvement model as we move towards greater sustainability.
Utilities continues to collaborate with UNC-Charlotte, Centralina Council of
Goveiranerits, and CPCC to assess the feasibility of using problematic fats, tail and
grease (FOG) as bio iesel feedstock. This feasibility study of alternative fuel has
been awarded grant fiends from the Biofuels Center of NC and the NC Green fund.
The study is investigating brown grease use as an alternative fuel' product to

A clog can have a bigger impact than people may
think. Clogs cause unitary Sewer Overflows ( a aka),
spilling raw sewage into a street, a stream or every
your own home.
Even products labeled as "flushable"° do not
decompose in the sewer system and can contribute
to clogging.

Description of collection and treatmenj[stems.
Charlotte -Mecklenburg Utilities collects wastewater from an estimated 219,268 connections to
households and businesses throughout the county. Wastewater is collected and directed (via
gravity flow supported by sewage lift stations) to one of five wastewater treatment plants where,
is treated. An average of 86 million gallons of wastewater is treated and discharged each day.
More than 150 employees work to maintain 3,865 miles of collection pipelines and 74 sewage fil
stations throughout the county. The gravity sewer pipes in this system range in size from 8 inche
in diameter to 78 inches in diameter.
2

Each of the wastewater treatment plants provides primary, secondary and advanced treatment to
the waste stream. Large solid particles and inorganic materials are removed by screening and
settling. The wastewater is treated biologically to remove dissolved pollutants. Disinfection
reduces bacterial and pathogenic materials. Finally, the waste stream passes through sand filters to
remove very small particles that may not have been removed through the settling process.
11. Summary of System Performance
How did we do?
Utilities had 421 sanitary sewer overflows (419 in collection system and 2 at a
wastewater plant) this year which by number is 51 more than last year. The volume of
wastewater that overflowed increased by 85 percent, from 329,038 gallons in fiscal year
2006 to 1,638,445 gallons this year. prior to the past two years, the fiscal year of 2005
and 2004 had 2,296,207 and 736,967 gallons spill respectively. Stated another way,
approximately 11 spills per 100 miles of pipe in the ground overflowed from the
collection system this year as illustrated by the table below.

While overflows remain our major focus, it is important to note that this amount
represents 0.00518 % of the total flow transported, and that the Charlotte -Mecklenburg

a
wastewater collection system successfully delivered more than 99.9948 percent of thi
community's 31.5 billion gallons of wastewater for treatment last year.
Utilities works 24 hours a day, 365 days per year to prevent and respond to overflows
Crews prevent overflows by clearing pipes of tree roots and grease, as well as replach
broken and aging pipes. Utilities has also increased its efforts to educate customers at
properly disposing of oils and grease.

additional sewer line cleaning, pipe rehabilitation/replacement efforts, capital improvements,
root control, grease disposal education and enforcement and other operational enhancements
have begun having a positive impact. See next page,for graph.

The Fecal Coliform Daily Maximum was exceeded on 6/18107 due to the repair and
testing of the UV system, The fecal coliform result was 2,400 cfu/I00ml. The repair
technician believed that the system would synchronize with Duke Power and there
would not be an interruption of power to the UV, The system did not synchronize and
there was a loss of power to the UV, which coincidedwith the daily sampling. This
resulted in a -7 minute loss of UV disinfection, during which the effluent sample was

The Fecal Coliform Daily Maximum was exceeded on 11/22/06 due to a very high flow rate
through the plant. All treatment systems were operational and the Ultra Violet (UV)
disinfection unit was at 100%. There are no obvious reasons fro this violation, other than
the high flows, which the UV system should have been able to treat. The weekly geometric

connections to house o s and businesses throughout the county. Wastewater is collected and
directed (mostly using gravity flow) to one of five wastewater treatment plants where it is treate
and released. An average of 75.6 million gallons of wastewater is treated daily.
More than 100 employees work to maintain 2,956 miles of sewer pipelines and 62 lift stations
throughout the county. The sewer pipes in this system range in size from 8 inches in diameter to
78 inches in diameter.

Wastewater treatment basically works like this:
I . Primary Treatment — Larger solid particles and objects are captured in grit screens and
primary clarifiers. Solids removed during treatment are safely recycled as part of a land
application program.
2. Aeration — Wastewater is aerated to encourage growth of specific microscopic organisms
that remove pollutants.
3. Clarification — Remaining solids settle out in large basins before the water is disinfected.
4. Discharge — Disinfectant is removed, then the water is discharged back into creeks to flow
downstream.
H. Performance
Charlotte -Mecklenburg Utilities safely collected, treated and discharged almost 28 billion
gallons of wastewater for the fiscal year ending June 30, 2000. Our wastewater collection systeir,
