Charlotte-Mecklenburg Utilities
Annual Report on Interbasin Transfer
Calendar Year 2004
Charlotte Mecklenburg Utilities (Utilities) operates the water and wastewater system that
serves the City of Charlotte, Cornelius, Davidson, Huntersville, Mint Hill, Matthews,
Pineville, and much of the unincorporated areas of Mecklenburg County. This utility
system, covering most of Mecklenburg County, is divided between two river basins as
designated by NC General Statutes. The western portions of the system are within the
Catawba River basin and the eastern portion is within the Rocky River basin. Water that
is transferred from the Catawba River basin to the Rocky River basin that is not returned
to the Catawba is defined as interbasin transfer (IBT).
Water is withdrawn from the Catawba River basin at two locations. An intake at Lake
Norman sends water to the North Mecklenburg Water Treatment Plant. A second intake
at Mountain Island Lake sends water to the Franklin Water Treatment Plant and the Vest
Water Treatment Plant. Potable water from these three plants is delivered through an
interconnected distribution system to customers throughout Mecklenburg County.
Utilities treats wastewater at five advanced wastewater treatment plants (WWTP’s) which
discharge into small streams in Mecklenburg County. Four of the streams are tributary to
the Catawba River basin and one (Mallard Creek) is tributary to the Rocky River basin.
Utilities also sends wastewater from several portions of Mecklenburg to the Rocky River
Regional Wastewater Treatment Plant (RRRWWTP) operated by the Water and Sewer
Authority of Cabarrus County (WSACC). The RRRWWTP discharges in the Rocky
River.
Utilities transfers treated, potable water to the City of Concord through several metered
connections to their water system. Water is transferred as an emergency back-up to
Concord’s routine supply which comes from Lake Howell and several smaller reservoirs.
All of these reservoirs are within the Rocky River basin. Wastewater from Concord is
treated at the RRRWWTP. Utilities’ agreement with Concord is that water can be
supplied to them subject to availability from the Charlotte-Mecklenburg system and
subject to regulatory constraints including IBT and Federal Energy Regulatory
Commission (FERC) limitations.
Charlotte Mecklenburg Utilities’ petition to increase the amount of water transferred
from the Catawba basin to the Rocky River basin was approved by the North Carolina
Environmental Management Commission (EMC) on March 14, 2002. The petition
allows Utilities to transfer up to 33 million gallons per day (mgd) from the Catawba
River basin to the Rocky River basin.
The approved petition requires Utilities to report daily IBT amounts annually to the North
Carolina Division of Water Resources until such time as the transfer amount exceeds
80% of the authorized amount, which would be 26.4 mgd. Once that amount is
exceeded, Utilities is required to report monthly. To date, Charlotte-Mecklenburg
Utilities has not exceeded 80% of the authorized IBT amount.
Table 1 below summarizes 2004 daily IBT amounts. The table considers the daily
amounts of water delivered from the Catawba basin to customers within Mecklenburg
County based on combined pumping records from the three water treatment plants. The
values shown in Table 1 include the amount of water transferred to the City of Concord
through metered connections. Transfers to Concord are included as average daily values
over the billing period which is approximately monthly. The full amount transferred to
Concord is IBT since none is returned from Concord to the Catawba basin. Daily
wastewater treatment plant discharges are used to determine how much flow is returned
to the Catawba basin and how much is discharged directly to the Rocky River basin from
Utilities’ Mallard Creek WWTP. Wastewater flows sent to RRRWWTP (and thereby
discharging into the Rocky River basin) are included in Table 1 as average daily flows
based on wastewater flow meter readings which are made approximately monthly.
Consumptive use within the Rocky River basin is considered IBT according to North
Carolina statutes. Consumptive use occurs due to septic tank systems, lawn irrigation,
inclusion of water in packaged products, evaporation, and other uses. The amount of this
consumptive use is estimated based on criteria described in Utilities’ IBT petition.
Combination of the data allows the calculation of the daily IBT amount. Table 1 presents
these amounts both as a percentage of the authorized amount and as a daily transfer
amount in mgd. The data is also presented in two charts which depict graphically the
IBT amounts.
The data indicates that the maximum amount of IBT for year 2004 occurred on May 26,
2004, and was 19.99 mgd, or 60% of the authorized maximum day value of 33 mgd. The
average IBT for 2004 was 13.18 mgd, which is about 40% of the authorized maximum
day value.

Condition 1 of Utilities’ IBT certificate requires Mecklenburg County to summarize
progress in implementation of watershed management approaches of the Surface Water
Improvement and Management Program (S.W.I.M. program). This summary follows:
Basic countywide water quality modeling capabilities have been developed and
are being upgraded to include advanced modeling capabilities for planning/land
development. A fully functioning water quality model has been developed for
McDowell Creek in the Town of Huntersville where rapidly degrading water
quality conditions have been experienced due to growth within the watershed.
Outputs from the McDowell model were used to develop a watershed based
approach for identifying alternative management strategies targeted toward
preventing further water quality degradation. As a result of this effort, a
performance based land development ordinance was developed that relies on Low
Impact Design (LID) strategies to protect water quality from future development
activities, which was adopted by the Town of Huntersville on February 17, 2003.
Water quality modeling and watershed based planning initiatives are also being
used in the design of two (2) large mixed use developments along Lake Wylie to
protect water quality from land development activities. Other S.W.I.M. initiatives
and actions in 2004 include:
• Secured grant funds, obtained properties and developed design
drawings to retrofit water quality BMP’s in the McDowell Creek
watershed;
• Implemented fecal coliform TMDL measures in Little Sugar, Sugar,
and McAlpine Creek basins;
• Development of a draft Low Impact Development (LID) ordinance for
the Town of Mint Hill designed to protect water quality conditions in
Goose Creek from non-point source pollutants associated with post-
construction storm water runoff; and
• Obtained grant funds and began design of pilot LID structures in the
Goose Creek basin to demonstrate compliance with the draft LID
ordinance.
Condition 2 of Utilities’ IBT certificate requires a report on the stakeholder process to
investigate water quantity control from single-family development and water quality
control for all development until that process is completed. The condition suggests that
the feasibility of single-family detention should be considered along with any needed
ordinance revisions. This report follows:
A water quality ordinance adopted by the Town of Huntersville in 2003 provides
water quality controls for single-family development as well as establishes
requirements for single-family detention within the Town limits and within their
zoning jurisdiction. This geographic area spans Mecklenburg County from west to
east and includes significant areas of the Catawba River (Mountain Island Lake)
watershed and the Rocky River basin. The Huntersville Ordinance was designed to
address both water quality and detention. The basic objectives of the Huntersville
Ordinance are:
¾ Minimize increases in storm water runoff from development or redevelopment in
order to reduce flooding, siltation and streambank erosion, and maintain the
integrity of stream channels.
¾ Utilize Low Impact Design (LID) strategies to minimize increases in non-point
source pollution caused by storm water runoff from development or
redevelopment. The goal of LID is to develop site design techniques, strategies,
and BMPs to store, infiltrate, evaporate, retain, and detain runoff on the site to
more closely replicate pre-development runoff characteristics and to better mimic
the natural and unique hydrology of the site thereby limiting the increase in
pollutant loads caused by development.
¾ Minimize the total volume of surface water runoff that flows from any specific site
during and following development in order to replicate pre-development
hydrology to the maximum extent practicable.
¾ Reduce storm water runoff rates and volumes, soil erosion and non-point source
pollution, to the extent practicable, through storm water management controls
(BMPs) and to ensure that these management controls are properly maintained
and pose no threat to public health or safety.
The performance criteria contained in the Huntersville Ordinance are :
¾ All storm water treatment systems used to meet these Performance Criteria shall
be designed to achieve average annual 85% Total Suspended Solids (TSS)
removal for the developed area of a site. Areas designated as open space that are
not developed do not require storm water treatment. All sites must employ LID
practices to control and treat runoff from the first inch of rainfall.
¾ LID practices or a combination of LID and conventional storm water
management practices shall be used to control and treat the increase in storm
water runoff volume associated with post-construction conditions as compared
with pre-construction (existing) conditions for the 2-year frequency, 24-hour
duration storm event in the Rural and Transitional Zoning Districts. For all
other Zoning Districts, LID practices or a combination of LID and conventional
storm water management practices shall be used to control and treat the increase
in storm water runoff volume associated with post-construction conditions as
compared with pre-construction (existing) conditions for the 1-year frequency,
24-hour duration storm event. This may be achieved by hydrologic abstraction,
recycling and/or reuse, or other accepted management practice as described in
Section 6 of the Huntersville Water Quality Design Manual.
¾ Where any storm water BMP employs the use of a temporary water quality
storage pool as a part of its treatment system, the drawdown time shall be a
minimum of 48 hours and a maximum of 120 hours.
¾ Peak storm water runoff rates shall be controlled for all development above 12%
imperviousness. The peak storm water runoff release rates leaving the site during
post-construction conditions shall be equal to or less than the pre-development
peak storm water runoff release rates for the 2-year frequency, 24-hour duration
storm event and 10-year frequency, 24-hour duration storm event. The
emergency overflow and outlet works for any pond or wetland constructed as a
storm water BMP shall be capable of safely passing a discharge with a minimum
recurrence frequency of 50 years. For detention basins, the temporary storage
capacity shall be restored within 72 hours. Requirements of the Dam Safety Act
shall be met when applicable.
¾ No one BMP shall receive runoff from an area greater than five (5) acres.
However, the total drainage area from BMP’s used in series (i.e., integrated) can
exceed this five (5) acre maximum.
In 2004, Mecklenburg County began work to develop ordinances to control and
manage storm water runoff and water quality impacts resulting from post-
construction storm water discharges in other areas of Mecklenburg County. This
work has four objectives:
1. Compliance with Phase I and Phase II NPDES Storm Water Permit requirements;
2. Address storm water pollution criteria specified by the NC Wildlife Resources
Commission and the US Fish and Wildlife Serve for the Rocky River / Yadkin
River basin;
3. Address the causes of impairment indentified in the NC 2002 Integrated 305(b)
and 303(d) Report for Surface Waters in Mecklenburg County;and,
4. Address detention measures for the control of storm water volumes and peaks
associated with new construction.
The development of the ordinance provisions is involving approximately 18
stakeholders representing interests such as realtors, Chamber of Commerce, local
government jurisidictions, home builders, environmental groups, and marine
commissions. Staff and other technical support is provided to the stakeholders by
Mecklenburg County, City of Charlotte, NC Wildlife Resources Commission, US
Fish and Wildlife Service, NC DENR, and SC DHEC.
Mecklenburg County has contracted with leading consultants to develop water
quality models and provide additional technical support to the process. The
detailed modeling is being used to evaluate the effectiveness of various
methodologies and techniques in meeting water quality and hydrology goals. The
stakeholder phase of this work is expected to be completed in 2005. The next step
is for the results of this phase to be incorporated into draft ordinances and
presented to the political jurisdictions within Mecklenburg County for adoption.
Condition 3 of the IBT certificate imposes a moratorium on the installation of new IBT
water lines (water lines crossing the ridgeline) into Goose Creek subbasin until the
impacts of additional growth on the endangered species are fully evaluated. This
moratorium remains in place.
Condition 4 of the IBT certificate provides that the Environmental Management
Commission may reopen the certificate under certain circumstances. This did not occur
in 2004.
Condition 5 of the IBT certificate requires Utilities to develop a compliance and
monitoring plan for reporting maximum daily transfer amounts, compliance with
certificate conditions, progress on mitigation measures, and drought management
activities. At the direction of NCDWR staff, Utilities developed a reporting format and
spreadsheets that were submitted in draft form for calendar year 2003. Not having been
informed otherwise, Utilities assumes this format is satisfactory.
Weather conditions in 2004 did not require implementation of drought management
activities. However, Utilities is working with Duke Power, NCDWR, and other water
users in the Catawba River basin to develop drought management plans to be included in
the Federal Energy Regulatory Commission (FERC) relicensing of Duke Power’s
hydroelectric facilities in 2008. This plan, referred to as the “Low Inflow Protocol” (LIP)
will establish trigger mechanisms for multiple drought stages and prescribe actions that
water users are to take at each stage. It is expected that development of the LIP will be
completed in 2005 or early 2006 with implementation to follow.
In summary, Utilities is in full compliance with IBT authorizations and compliance
conditions. Utilities continues to work cooperatively with Mecklenburg County and
other jurisdictions in our service area to develop and implement programs to support
growth and mitigate direct and secondary impacts.
