Description of collection and treatment systems:
Charlotte-Mecklenburg Utilities collects wastewater from an estimated 226,978 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 it
is treated. An average of 83 million gallons of wastewater is treated and discharged each day.
More than 150 employees work to maintain 4,047 miles of collection pipelines and 74 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 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.
2
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 fine particles.
5. Disinfection
Water is disinfected to remove any remaining pathogens, and then the water is released back
into creeks to flow downstream.
II. Summary of System Performance
How did we do?
We are meeting all reporting deadlines and requirements of the federal EPA
Administrative Order to reduce spills, and the EPA approved two of our key reports
regarding our Sewer Capacity Assurance and Fats, Oils and Grease prevention programs.
We successfully collected and treated 99.997 percent of the more than 30 billion gallons
of wastewater the community produced last year. There were 349 sewer spills in our
community, a decrease of nine spills compared to the year before. In fact, the number of
spills per 100 miles continued to decline from 10.9 in 2007 to 8.6 spills in fiscal year
2010 as illustrated by the table on page 4.

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 replacing
broken and aging pipes. Utilities has also increased its efforts to educate customers about
properly disposing of oils and grease.
Performance Highlights
Charlotte-Mecklenburg Utilities celebrated some important milestones even as it took
numerous actions to prevent overflows and protect water quality through effective
wastewater treatment.
• Our wastewater treatment plants met 99.99 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 2009. 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. McDowell Creek
Wastewater Treatment Plant earned a Platinum Award for a second year, which
means six consecutive years of perfect compliance. Mallard Creek Wastewater
Treatment Plant received a Platinum Award for five consecutive years of perfect
compliance. Gold Awards were presented to McAlpine Creek and Irwin Creek
Wastewater Treatment Plants for perfect compliance. Sugar Creek Wastewater
Treatment Plant earned a Silver Award for five or fewer violations in a one-year
period.
• 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 same
location) by Field Operations and 14.3 miles of pipe were cleaned by contractors.
More than seven miles of large diameter pipe was also cleaned by contractors.
264 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 sanitary sewer pipes and to help prevent root intrusions.
After replacing nine hydraulic jetting / 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 SSOs as those that occurred this period
from occurring in the future.
Utilities is proceeding with the implementation of a Work and Asset Management
(WAM) 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 2010. 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 collection
system, including inspection of manholes and any exposed piping. This multi-year
project is estimated to cost more than $5,000,000. The project is collecting data that
will be used as part of the foundation of a new geographic information system (GIS)
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 sizes, construction materials, and other
information. This survey is approximately 95% complete.
Utilities continued contracting for biological grease treatment in several selected
areas of the collection system. Since treatment began in March 2007, only two grease
related SSOs have been reported along 42,000 ft. of treated lines and the regular
removal of grease from a downstream pump station wet well has been eliminated.
Utilities recently renewed the biological grease treatment contract.
Utilities continuous improvement and optimization efforts expanded again this year.
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. 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 Environmental Management System
Protection. 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
Governments, and CPCC 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 funds from the Biofuels Center of NC and the NC Green Fund.
The study is investigating 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 will consider conventional costs and total
life cycle impact assessment. Final reporting is expected in early 2011.
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 is using up to 500,000 gallons a day during spring
and summer time. Mallard Creek Park is using up to 500,000 gallons each month.
There were 74 Wastewater Lift Stations serving our low-lying areas. Staff performed
125 preventative maintenance tasks for a total of 1985 work hours. This does not
include twice weekly station checks, wet well cleaning, emergency generator testing,
or emergency/routine repairs.
Griffith Street Lift Station was upgraded with new pumps, generator, electrical
service, controls, and wet weather storage. Old Steele Creek Lift Station was removed
from service due to new gravity line.
Phase one of the Briar Creek Relief Sewer project is more than 98% complete. Construction of
phase two will begin fall 2010.
Phase one of the McAlpine Creek Relief Sewer project was completed and in service on
December 21, 2009. Construction on phase two began in FY 2010 and was 75% as of June 30,
2010.
Last year’s frequency of sewer spills was below the 5-year average in seven of the twelve
months.

City staff inspected grease-handling facilities at 4,217 food service establishments
and restaurants (not including follow-up inspections) to ensure proper grease disposal.
The City continued its Grease Free education program to teach proper disposal of a
pipe-blocking menace. Inspectors mailed information to more than 4,506 customers
and handed out information to 9,582 customers in apartments / multi-family
complexes.
Staff conducted more than 159 presentations to more than 5,900 children and adults.
Some of the key presentations were to ten apartment property managers and
plumbers. Multiple Earth Day events also provided opportunities to distribute Grease
Free scrapers, pens and other items.
Utilities participated at the Greater Charlotte Apartment Association Trade Show in
March 2010, which was very successful in talking with property managers, owners
and maintenance staff about grease disposal methods and preventative maintenance.
We continue to provide bilingual doorhangers and promotional items for property
managers to give to new residents.
Utilities employed a new doorhanger specifically for maintenance personnel or
property manager of apartment or multi-family complexes. This reinforces best
management practices for prevention.

Advertised in a popular direct mail coupon book (above), WelcomeMat, that new
single-family and multi-family residents receive monthly. The Utilities “coupon”
explains proper disposal methods and offers a free grease lid. The ads ran from
August 2009 through June 2010.
Provided copies of our 30-second TV advertisement to the Charlotte-Mecklenburg
Schools and WTVI to run on their stations as inventory allows. CharlotteMecklenburg Schools runs CMS TV targeted to students and parents at home, while
WTVI is the Charlotte region’s PBS affiliate.
Secured and provided two volunteers to speak on a Spanish radio news talk show in
Charlotte named Punta Latina to describe the consequences of improper grease
disposal and inform customers. One expert on the show was a bilingual Utilities
employee, while another was a Latina apartment leasing agent in our community. The
show aired October 22, 2009.
Work continues on our statewide Urban Water Consortium-funded research project.
UNC Charlotte is conducted focus groups and surveys this spring/summer to inform a
strategic communications plan for better reaching multi-family and Latino customers
with Grease Free messages.
Utilities continues to distribute bilingual door hangers to apartment managers and at
community presentations and events. We are also providing pan scrapers and jar
openers with the bilingual Grease Free message.
Along with ongoing media notifications about spills, customers within 1,000 feet of a
grease-caused spill receive a letter alerting them of the spill and how to properly
dispose of grease.
Bill inserts in October, November and December mailed (example on next page) to
nearly 250,000 customer account holders each month. These also were repurposed as
messages on our web site, and extra inserts were made available at events during
those months.

Continuing Challenges
Wastewater Collection Challenges
The volume of wastewater that overflowed increased from 383,859 gallons in fiscal year
2009 to 813,044 gallons in fiscal year 2010. The volume of wastewater that reached
surface waters also increased from 303,287 gallons in fiscal year 2009 to 661,883 gallons
in fiscal year 2010.
The greatest continuing wastewater challenge in this community – and in others across
the U.S. – is sewage overflows. Of the 349 sewer spills that occurred, more than half
were due to hardened grease clogging pipes. Other spill causes included the infiltration of
tree roots into pipes, vandalism, general debris, and broken pipes.
Fiscal Year 2010 Overflows by Primary Cause
9
Grease and other blockages that lead to sewer overflows are cleared by Utilities crews, using
various cleaning methods, including mechanical rodders 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.
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.
Charlotte-Mecklenburg Utilities continues its excellent sewage spill response record. Staff
responded to more than 96 percent of the spills in less than 60 minutes. This compares to a state
response standard of 120 minutes or less.
Utilities has continued to evaluate and refine sewer cleaning operation. A significant
change of strategy was continued during this fiscal year relative to how cleaning
resources are assigned. Utilities initiated a Consolidated Cleaning Project in January
2009. Under the direction of the Field Operations Senior Engineer, and using our SSO
data base and GIS, sub-basins with high concentrations of system failures and SSOs are
being identified. Resources from each of the Field Operation Zones are pooled or
consolidated in these problematic sub-basins and deliberate and focused cleaning,
inspection, and repair efforts are directed from the top to the bottom of the sub-basins.
During this year, six sub-basins have been completed. Within these basins,
approximately 310,010 linear feet, or 58 miles, were cleaned using hydraulic / vacuum
combination machines, rodders, and off-street hydraulic equipment. The line segments
were then inspected using CCTV. Main line deficiencies were identified and repaired.
Data is being collected during the Consolidated Cleaning Project to evaluate this
approach, adjust from lessons learned, and to redeploy the process over the four
geographic zones of our collection system in the future. The consolidated project
approach also insures that preventative maintenance to reduce SSOs is not impacted by
other service emergencies. This consolidated project approach; in addition to the
ongoing preventative maintenance directed by each zone; is expected to reduce SSOs
caused by grease, roots, debris, and system defects such as broken pipe and off-set joints.
Utilities remains optimistic that this approach will deliver continuous improvements in
spill reduction.
Several spills during this period were exceptional, unintentional, temporary, and caused
by factors beyond the reasonable control of Utilities. Within this period, four severe rain
events of several inches within a very few hours produced major flash flooding resulting
in eighteen (18) SSOs. These events occurred November 11th and December 25th of 2009
and January 25th and February 5th of 2010.
Charlotte-Mecklenburg Utilities continues to deal with severe budget constraints during
these recessive economic times. A hiring freeze has continued prompting Utilities to
reallocate positions in order to reduce SSOs.
10
The five-year moving average now stands at 371.6 collection system spills per year (from fiscal
year 2006 to present- fiscal year 2010).
Number of Spills Compared to 5-Year Average
Utilities tracks, trends, and analyzes the effectiveness of its efforts in reducing SSOs. On a
monthly basis Utilities studies SSOs trends, including: a comparison of the current month’s SSO
total and SSOs experienced the same month during the previous year, SSOs per 100 miles of pipe,
SSOs versus the five year average number of SSOs, and SSO volume.
U.S. Environmental Protection Agency (EPA) Administrative Order Update
Charlotte-Mecklenburg Utilities performed a voluntary sewer system 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 Utilities met several times to review the audit and
actions taken since 2000. Utilities 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
Utilities. This Administrative Order is a regulatory enforcement action that includes a series of
steps Utilities must take to reduce overflows in our community. These steps included paying a fine
for past spills and assuring that certain construction projects would be completed on time. The
administrative order will help guide our ongoing efforts to address a community problem we’ve
been working on for many years. Utilities will continue to update the EPA on its progress.
Charlotte is 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 have
11
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 will help further guide our ongoing efforts to address a community
problem. We have increased preventative line maintenance, capital improvements and other
programs.
The EPA’s and our goal for overflows is zero. Reality is that a system our size will always have
some overflows, but we agree even one spill is too many. Zero spills continue to be our standard
and goal in Charlotte-Mecklenburg.
Wastewater Treatment Plant Challenges
Charlotte-Mecklenburg Utilities five wastewater treatment plants met 99.93 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 performance. Major
rehabilitation and improvement projects help maintain compliance. Future upgrades and
expansions are being added.
During this fiscal year there was one permit limit violation out of a potential of 7,261
compliance tests.
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.
On June 30, 2010, Heavy rains caused wastewater to overflow at the Sugar Creek
Wastewater Treatment Plant. An estimated 83,000 gallons reached Sugar Creek.
Operators responded immediately and diverted excess rain water to back-up basins and
took appropriate cleanup/repair action.
Utilities operates a system protection program to help maintain our infrastructure. This
Pretreatment program has identified, permitted, and regulated large industrial users and
others to keep unsuitable discharges out of the wastewater system. While industrial
compliance is extremely high in Charlotte-Mecklenburg, identifying potentially
hazardous discharge sources is an ongoing challenge. In fiscal year 2010, the Trunkline
Monitoring and Grease Free programs also continued, enabling Utilities System
Protection and Water Quality staff to closely observe what industrial, institutional, and
commercial customers discharge into the sewer network, identify potential problem areas,
and protect the collection system, sewer line workers, and treatment plants.
Wastewater Capacity Needs
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. Two of the larger, near-term projects include an expansion at the Sugar Creek
Wastewater Treatment Plant and a new regional wastewater treatment plant along the
Catawba River, near its intersection with Long Creek. Both projects will take years and
