The first line type identified as “Other”, with 24 to 48 inch size range, is concrete pipe. The next line type identified as “Other”, with 1 to 2 inch size range is copper. The final line type identified as “Other”, with 2 inch pipe is HDPE.

The City's hydrant flushing program is managed by the Concord Fire and Life Safety Department.
A valve exercise program was initiated in 2010 and is in the process of being revised to be more comprehensive and regular.
In November 2011, a program was instituted that provides a $50 credit per toilet on customer's water bills for proof of replacement of old high flow toilets with WaterSense labeled toilets.
The City of Concord hires an outside company to conduct a Leak Survey of approximately 10% (approximately 80 miles) of our distribution system per year. This survey is done using acoustic and correlation techniques. The goal is to survey our whole system over the span of 10 years.
In addition, a contractor is notified when a leak is suspected in the Concord water system, and the contractor locates the leak via acoustic correlation techniques. An open contract for the performance of this service is maintained to ensure that the City has the ability to respond and investigate any potential leaks as soon as possible.

Concord and the Water and Sewer Authority of Cabarrus County continue to look for opportunities to use reclaimed water in an economically feasible situation.

The population served includes Concord, Midland, and a small portion of unincorporated Cabarrus County. The year round population value is derived by multiplying the number of residential meters (46,823) by the average Concord household size from 2015-2019 U.S. Census Bureau Quick Facts data (2.62 persons/household). This population figure is not exact, but should be representative of the population served by the system as a whole.

Metered connections are based on the total number of meters throughout the year. This number is affected by the AMR to AMI meter changeout.
Residential meters include customers inside and outside of the municipal limits, in addition to separate outdoor irrigation and spigot accounts. Commercial meters include customers inside and outside of the municipal limits, in addition to separate outdoor irrigation and spigot accounts. Concord went through a process this year of categorizing “institutional” customers as the following: schools, churches, prisons, etc.
System process water was calculated by subtracting the total finished water pumped (3958.890) from the total raw water withdrawal (4461.279) by both Coddle Creek and Hillgrove Water Treatment Plants for CY 2024, which is 502.389 MG. This is an average of 1.376 MGD. We added an estimated 0.38 MGD for the water used for flushing throughout the City, based on the timing of our automatic blow offs. We also added 0.019 MGD for tanker truck usage. Thus 1.775 MGD was our final amount for system processes.

Aqua Inc. operates a water system for the Springdale residential subdivision. Utilities Inc. operates a water system for the Zemosa Acres subdivision. No contracts exist between the City of Concord and these utilities. Service is provided to these utilities in the same manner that service is provided to any other Concord customer.

Concords contract with Charlotte Water was signed in 2002. The term of this contract provides for an automatic renewal every five years. Concords contract with Kannapolis was renewed in 2021 for a 10-year term. Concords contract with Harrisburg was signed in 2018 for a 5-year term and has been renewed annually since then. A new long-term contract is currently being negotiated to be into place before 6/30/25. Concords contract with Mt. Pleasant was signed in 2004 as a regular water connection and expired in 2016. There was a 2-year renewal period to 2018, and has only been used for emergency since that contract expired. Mount Pleasant was doing major work on their water treatment plant for the second half of 2025, and we were their water supplier during that time period.

A portion of the jurisdiction of Mecklenburg County (Concord-Huntersville Road area) was served by the City of Concord until late 2021. The City also has many other master-metered connections to customers such as mobile home parks, apartment complexes, churches, and schools that may or may not have assigned public water system identification numbers. Water sales for each of these customers are based on meter size and usage. Certain areas within the jurisdiction of the City of Kannapolis are also served by Concords water system due to the proximity of the water systems to those properties. Additionally, a portion of the water system owned and operated by the City of Concord serves as the primary water system for the Town of Midland. Users in these areas are billed directly by the City.

Concord has two contracts with Kannapolis. One for IBT use (0.772 MGD average use and 2.0 MGD contract), and one for everyday normal use (0.588 MGD average use, and 1.5 MGD contract).

The numbers in this section are based on the City of Concord’s monthly drought report spreadsheets. Each number is the sum of the raw water withdrawn for Lake Don T. Howell, Lake Fisher, and Lake Concord plus the finished water purchased from Albemarle, Kannapolis and Charlotte Water.

In CY 2025, a total of 1771.518 MG of finished water was purchased from Albemarle, a total of 0.171 MG of finished water was purchased from the City of Kannapolis and no finished water was purchased from Charlotte Water.

The total permitted raw water withdrawal from Lake Don T. Howell (Coddle Creek reservoir) is 13.9 MGD. This reservoir also serves the City of Kannapolis. Concord’s usable volume is 11.3 MGD by agreement between Concord and Kannapolis, based upon the percentage of the reservoir’s operation and maintenance cost paid by Concord. A minimum flow is required downstream of Lake Don T. Howell in Coddle Creek.

The City of Concord (Rocky River Basin) currently has emergency interconnections with Charlotte-Mecklenburg Utilities (Catawba River Basin) that will eventually become regular interbasin transfer locations at such time the demand becomes great enough. The completed water line from Albemarle (Yadkin River Basin) has been an additional regular interbasin transfer. An Interbasin Transfer Certificate was issued January 10, 2007 by the Environmental Management Commission approving these transfers.

Certain individual customers are served by Charlotte-Mecklenburg Utilities and the City of Kannapolis due to proximity of their water systems to those properties at the time they were developed. The City of Concord is billed monthly based on customer meter reading.

The purchase water contract with Charlotte Water is listed as a regular use connection to account for the ability that Concord has to purchase up to 5 MGD as needed.

In CY 2025, a total of 1771.518 MG of finished water was purchased from Albemarle, a total of 0.171 MG of finished water was purchased from the City of Kannapolis and no finished water was purchased from Charlotte Water.

The Water and Sewer Authority of Cabarrus County (WSACC) provides regional wastewater treatment for the City of Concord, City of Kannapolis, Town of Harrisburg, Town of Mount Pleasant, Town of Midland, and Charlotte-Mecklenburg Utilities. The Average Daily Discharge provided in this section is the result of the monthly flow that WSACC billed Concord divided by the number of days in the month. This number includes discharges from the Town of Midland as well. Concord is the water and sewer provider for the Town of Midland. The number of sewer service connections is based on the total number of sewer billing accounts that the City of Concord had in December 2025. The number of water service connections with septic systems is based on a coding in the billing system that tracks meters that are not charged for sewer that are not irrigation meters.

The City of Concord does not own or operate a wastewater treatment facility; however, WSACC completed the first phase of an expansion to gain sewer capacity in FY2024, with the second phase to be completed in FY2027 at the Rocky River Regional Wastewater Treatment Facility (NC0036269) for the purposes of WSACC meeting the existing permitted capacity of the plant facility. They are also currently working on design for an additional expansion.

Discharge permit NC0083119 regulates the lagoon discharge from the Coddle Creek Water Treatment Facility. The permitted capacity, 0.6 MGD is a monthly average limit. Concords maximum day discharge occurred on February 13, 2025.

Permit WQCS00326 had an estimated maximum discharge of 22.859 MGD. This number was calculated by multiplying Rocky River Wastewater Treatment Facilitys max day discharge by 50%, based on Concord using an average of 50% of the flow at Rocky River Regional Wastewater Treatment Facility and adding the max of 0.699 from Muddy Creek.

The Citys wastewater collection system (WQCS00326) discharges to two NPDES facilities owned and operated by the Water and Sewer Authority of Cabarrus County (WSACC). Rocky River Regional Wastewater Treatment Facility (NC0036269) and Muddy Creek Wastewater Treatment Facility (NC0081621).
Average daily discharge under permit WQCS00326 is recorded in the interconnection section below.

No contractual limit exists for the amount of wastewater flow WSACC will accept from the City of Concord. Concord is billed based on WSACCs sewer meter data. Surcharge fees may be assessed for excessive inflow and infiltration.
Certain individual customers in other jurisdictions are served by Concords wastewater collection system due to topography and the systems proximity to those properties. These customers are billed based on water meter readings, even though some of these customers receive water service from another jurisdiction.
