Wastewater Collection System
Piping Defect -Construction
As a follow-up to telephone and direct consultation on this situation, this communication at-
tempts to put things in chronological order.
Beginning in September, 2012 the Wastewater Plant experienced an increase in flow as meas-
ured by the effluent flow meter. The flow, in effect, had doubled on days of good weather. The
rain events pressed the effluent to astronomic amounts in this and subsequent months, peaking
at 0.170 MGD on one occasion.
Various attempts to find a specific point of inflow by direct inspection of manholes and pump-
ing stations were not successful. A complete inspection of the system was completed with all
lines being walked and all manholes inspected.
With the excellent aid of NCRWA, it was discovered that County Water was entering the sys-
tem. Iredell Water Corporation repaired the water leak and the flow subsided toward the previ-
ous normal volumes. A subsequent check of the sewer main in the same area of the water leak
revealed that the piping had not been connected in the borehole place under the roadway to ac-
commodate the installation. Repairs were completed and the system is now complete.
The situation was more distressing, due to massive amounts of soil solids entering the WWTP
each time it rained and appreciable amount, the flow increasing at the same event. These colloi-
dal solids have not exited the facility and are now collected in the clarifiers in a much thick-
ened consistency. This now poses a serious disposal problem that will not be inexpensive to
resolve.
The Town of Harmony thanks your staff for the information aid given to our operators. Any
further information will be submitted as developments progress.

Harmony Sewer Collection System
Wastewater Collection System Extension
'Catawb_a_County, North Carolina
Dear Mr. Campbell,
In accordance with your complete application received on August 18, 2008, we are forwarding
herewith Permit No. WQ0020841, dated August 28, 2008, to the Town of Harmony for the construction
only of the subject wastewater collection system extension. This permit shall be effective from the date
of issuance until rescinded, and shall be subject to the conditions and limitations as specified therein.
This cover letter shall be considered a part of this permit and is therefore incorporated therein by
reference.
Please pay particular attention to Permit Condition 3 which requires that the wastewater
collection facilities be properly operated and maintained in accordance with 15A NCAC 2T .0403 or any
individual system -wide collection system permit issued to the Permittee.
Permitting of this project does not constitute an acceptance of any part of the project that does
not meet 1) 15A NCAC 2T; 2) the Division of Water Quality's (Division) Gravity Sewer Minimum Design
Criteria adopted February 12, 1996, as applicable; 3) and the Division's Minimum Design Criteria for
the Fast -Track Permitting of Pump Stations and Force Mains adopted June 1, 2000, as applicable,
unless specifically mentioned herein. Division approval is based on acceptance of the certification
provided by a North Carolina -licensed Professional Engineer in the application. It shall be the
Permittee's responsibility to ensure that the as -constructed project meets the appropriate design criteria
and rules. Failure to comply may result in penalties in accordance with North Carolina General Statute
§143-215.6A through §143-215.6C, construction of additional or replacement wastewater collection

WASTEWATER COLLECTION SYSTEM EXTENSION PERMIT
This permit shall be effective from the date of issuance until rescinded and shall be subject to the following
specified conditions and limitations:
1. This permit shall become voidable unless the wastewater collection facilities are constructed in accordance
with the conditions of this permit; 15A NCAC 2H .0200; the Division of Water Quality's (Division) Gravity
Sewer Minimum Design Criteria adopted February 12, 1996 as applicable; the Division's Minimum Design
Criteria for the Fast -Track Permitting of Pump Stations and Force Mains adopted June 1, 2000 as applicable;
and other supporting materials unless specifically mentioned herein.
2. This permit shall be effective only with respect to the nature and volume of wastes described in the
application and other supporting data.
3. The wastewater collection facilities shall be properly maintained and operated at all times. The Permittee
shall maintain compliance with an individual system -wide collection system permit for the operation and
maintenance of these facilities as required by 15A NCAC 2H .0227. If an individual permit is not required,
the following performance criteria shall be met as provided in 15A NCAC 2H .0227:
a. The sewer system shall be effectively maintained and operated at all times to prevent discharge to land
or surface waters, and any contravention of the groundwater standards in 15A NCAC 2L .0200 or the
surface water standards in 15A NCAC 2B .0200.
b. A map of the sewer system shall be developed prior to January 1, 2004 and shall be actively
maintained.
.c. An operation and maintenance plan shall be developed and implemented.
d. Pump stations that are not connected to a telemetry system shall be inspected at least three times per
week until July 1, 2000; thereafter, pump stations shall be inspected at least daily, as defined in 15A
NCAC.2B .0503(5), until July 1, 2001; and thereafter, pump stations shall be inspected every day.
Pump stations that are connected to a telemetry system shall be inspected at least once per week.
e. High -priority sewer lines shall be inspected at least once per every six-month period of time.
f. A general observation of the entire sewer system shall be conducted at least once per year.

15A NCAC 02T .0401 SCOPE
The rules of this Section apply to system -wide collection systems pursuant to G.S. 143-215.9B, where the
Director may issue system -wide permits for collection systems relating to operation and maintenance of
sewers, pump stations, force mains and all appurtenances.

15A NCAC 02T .0402 DEFINITIONS
The following definitions are used in this Section:
(1) "Collection system" means a public or private sewer system, consisting of sewer lines,
force mains, pump stations or any combination thereof that conveys wastewater to a
designated wastewater treatment facility or separately -owned sewer system. For purposes
of permitting, the collection system is considered to be any existing or newly installed
system extension up to the wastewater treatment facility property or point of connection
with a separately -owned sewer system.
(2) "High -priority sewer" means any aerial sewer, sewer contacting surface waters, siphon,
sewer positioned parallel to streambanks that is subject to erosion that undermines or
deteriorates the sewer, or sewer designated as high priority in a Division issued permit
where the sewer does not meet minimum design requirements.

are inspected by the permittee or its representative every day (i.e., 365 days per year).
Pump stations that are connected to a telemetry system are inspected at least once per
week.
