Fayetteville Public Works Commission
Fayetteville Public Works Commission enjoyed another year of truly excellent performance at both of our
treatment plants and the collection systems which they serve. Outside of upset conditions during Hurricane
Florence, we had no permit exceedances at either treatment plant,which is an extraordinary accomplishment
given the myriad of regulatory requirements we must meet. Our plants have been recognized by the NC
Department of Environmental Quality as "Exceptionally Performing Facilities." We had 38 events where
sewage was released from the collection system, and these occurrences were mostly due to factors beyond our
control or were related to Hurricane Florence. At both the treatment plants and in our sewage collection
systems,this is an extremely high level of service and system reliability that we will strive to maintain. The
following provides a summary of all collection system overflows and treatment plant permit exceedances.

Description:
This SSO was caused by debris which was inadvertently deposited in a sewer manhole by a contractor.
Corrective measures:
There was not an active spill at the time that PWC arrived on site, but there was evidence of a spill in the street
and the curb line. Inspection of the manhole revealed that asphalt had been introduced into the manhole during
recent paving operations by a contractor. Manhole entry was performed to manually remove the asphalt debris
while combination vacuum/jetter trucks maintained system sewer flows. The sewer main upstream and
downstream of the subject manhole was cleaned after removal of the debris from the manhole. No cleanup was
required of the street, curb line, and affected storm drainage system as a winter storm led to significant rainfall
at the spill location. The low volume of sewer entering the storm drainage system was heavily diluted by storm
water runoff. The sewer main upstream and downstream of the subject manhole was televised on 12/10/18 to
confirm that debris removal was complete.

ANNUAL PERFORMANCE REPORT
Corrective Measures:
A recent PWC sewer main rehabilitation project, done by a contractor, led to the main trunk line being lined
with a CIPP liner. During the lining process deformities in the liner were present which resulted in a blockage
of the service lateral for the subject location. PWC's rehabilitation contractor responded and corrected the
deformities in the liner to resolve the issue. The affected area was treated with lime and odor counteractant.
Event 25: Date: 1/3/19 Gallons: 20
Location:
255 Ann Street—sewer main under the new bridge
Description:
This SSO was the result of a contractor removing a plug in an existing sewer main as part of the installation of a
new section of sewer main. This was a City of Fayetteville contractor working on the Ann Street bridge project.
Corrective Measures:
Current bridge construction at the subject location required sanitary sewer utilities to be temporarily rerouted to
accommodate utility service to the upstream customer. As part of the new bridge construction,the City of
Fayetteville contractor installed a casing through the north bridge end bent for the installation of the permanent
sanitary sewer main. The contractor removed the sewer plug from the upstream manhole and began installing
the permanent piping. Upon partial installation of the piping, wastewater exited from the pipe and end bent
casing. The contractor attempted to re-plug the upstream manhole, but was unsuccessful due to a malfunction
of the air supply connector. The contractor immediately notified PWC and a crew responded and successfully
plugged the line in question at the upstream manhole ending the spill incident.

Event 27: Date: 1/20/19 Gallons: 2,150
Location:
3310 South Peak Drive—manhole outside pavement
Description:
This SSO was discovered while PWC maintenance personnel were working to stop a nearby SSO and clear that
blockage. The grease from the initial blockage was broken loose when it was cleared and the grease went to the
nearby lift station and clogged the pumps resulting in a high well alarm.
•
Corrective Measures:
A combination vacuum/jetter truck maintained the lift station wet well until the pumps could be unclogged and
made operational again. PWC staff discovered the overflowing manhole during their transit to decant liquid
from their debris body from the initial SSO on Footbridge Lane. The overflowing manhole is the discharge
manhole for the force main from the lift station in question. The overflow occurred twice during the incident
period, of which both times staff immediately contacted the PWC lift station staff to have them stop the lift
station pumps ending the spill incident. It was determined that both pumps were simultaneously in operation to
address the high well alarm at the station. Running both pumps simultaneously overwhelmed the downstream
gravity sewer and resulted in the overflow. When it was discovered that the manual operation of the pumps was
causing the overflow the lift station staff reduced pumping to a single pump allowing the downstream collection
system to return to normal flow. Wastewater exited from the manhole and ran down the roadway/curb line and
entered a nearby storm drainage system. The affected area was treated with lime and odor counteractant. Main
cleaning and CCTV inspections at the spill location began on 1/22/19.
Event 28: Date: 2/13/19 Gallons: 4,988
Location:
3200 Natal Street—manholes behind industry
Description:
This SSO was caused by grease and debris blockages in the sewer main.
Corrective Measures:
The sewer main was jet rodded to clear the grease and debris blockage and end the spill incident. At the time of
the spill there were five consecutive manholes overflowing. Two of the manholes were PWC owned and three
were owned by the private industry. Wastewater exited from all five manholes and some of the wastewater was
contained to the driveway and an adjacent grassy area. Some of the wastewater was able to reach a drainage
swell and run to a private pond. All of the wastewater exiting the manholes was heavily diluted due to a rainfall
event on 2/12/19. Wastewater was observed at all of the low lying areas in the spill location. . All areas of
ponding wastewater were vacuumed to reclaim the wastewater and the areas treated with lime and odor
counteractant. Main cleaning and CCTV inspections were completed.

Event 29: Date: 03/06/19 Gallons: 8,250
Location:
705 Robeson Street—manhole in easement on creek bank
Description:
PWC maintenance staff was replacing a section of 18" cast iron aerial sewer pipe while the line segment was
under bypass. During the bypass operation, the air connection port on the sewer plug failed allowing the air to
escape and deflate the plug.
Corrective Measures:
PWC personnel stationed at the suction manhole identified the malfunction immediately and implemented
pump and haul operations until the air connection port could be replaced. Once the fitting was replaced and the
plug re-inflated the incident ended. Wastewater exited from the manhole around the new piping which was
being installed. Once the aerial crossing pipe was installed the plug and the bypass system were removed and
the flow returned to normal.
Event 30: Date: 3/19/19 Gallons: 2,340
Location:
714 Westmont Drive—manhole in street and customer cleanout
Description:
This SSO was caused by debris in the sewer line.
Corrective Measures:
The sewer main was jet rodded to clear the debris blockage and end the spill incident. Wastewater exiting form
the manhole and the customer's cleanout entered the storm drainage system immediately discharging to a
drainage tributary. Wastewater and waste residue in the roadway and the customer's yard has been removed
and the areas cleaned up. The wastewater in the short span of the storm drainage system has been reclaimed.
The affected areas were treated with lime and odor counteractant. Main cleaning and CCTV inspections
upstream and downstream of the spill location began on 3/19/19. Misaligned pipe joints which were discovered
during CCTV inspection will be evaluated and corrected promptly.
Event 31: Date: 3/22/19 Gallons: 900
Location:
2536 Tracy Hall Road - 54" aerial pipe crossing entering reclamation facility
Description:
This SSO was caused by the WWTP being taken offline for an inspection of the influent grit chamber. In order
to complete that task and for the safety of the dive team both influent screw pumps were shut down around
9:53am. At around 10:10am PWC staff identified drips at three pipe joints during a routine inspection of the
aerial crossing which was unrelated to the WWTP work.

Corrective Measures:
Upon identifying the leaks, field personnel opened the upstream and downstream manholes and noticed
surcharging conditions were present. WWTP staff was notified of the incident and they advised WRC staff of
what was going on at the plant with the shutdown. WWTP staff turned the screw pumps back on around
10:31 am and field staff verified that the leakage had ended around 11:10am. Upstream and downstream
manholes were revisited to verify that the surcharge conditions had ended. No cleanup was required as
wastewater exiting pipe joints made direct contact with actively moving groundwater immediately entering
Rockfish Creek.
Event 32: Date: 3/28/19 Gallons: 150
Location:
1812 Conover Drive—manhole in street
Description:
The PWC lateral lining contractor was installing lateral liners along Conover Drive. As part of the process, a
"packing/launch rig" is inserted into the collector main via sewer manholes. The rig is maneuvered into
position at the service connections to begin the insertion process. Once positioned the packer is inflated to
protect the liner and the resin. The packer has flow thru capabilities; however it is not ideal for high flow
conditions. As a result, the collections system surcharged and wastewater exited from a manhole in the street.
Corrective Measures:
A PWC project inspector arrived at the work site around 11:45am and parked near the subject manhole; at the
time of his arrival there was not a spill occurring. The inspector walked to the contractor's work location, spoke
with the contractor, and returned to his vehicle to complete paperwork. Upon his return to the vehicle, he
noticed that wastewater was exiting the manhole. He immediately made contact with the contractor requesting
that the packer unit be deflated. During this time period other construction activity in/near the work zone was
occurring. Water Distribution personnel were flushing a nearby hydrant due to a water quality issue. The
hydrant was opened around 10:30am and was closed around 12:30pm. Wastewater exiting the manhole mixed
with the flushing runoff at its point of entry to the storm drain, heavily diluting the wastewater. The contactor
immediately deflated the packer unit ending the spill incident. The pavement and curb line were cleaned to
remove wastewater residue. No cleanup of the storm drainage was performed since the wastewater was heavily
diluted with potable water from the flushing operation.
Event 33: Date: 4/10/19 Gallons: 15
Location:
5744 Waters Edge Drive—PWC cleanout at the edge of the lake
Description:
This SSO was caused by a third party septic contractor. The contractor contacted PWC requesting assistance
with a service lateral blockage. Upon arrival PWC staff discovered that the plumber had removed the PWC
cleanout cap resulting in a sewer release.

ANNUAL PERFORMANCE REPORT
Corrective Measures:
The contractor entered the customer's cleanout with a"blow bag" and had also entered the PWC cleanout with
a rodding machine which resulted in the sewer release. PWC asked the contractor to stop their operations and
when they did the spill ended. PWC staff took over the operation and cleared the stoppage from the service
line. The stoppage was actually on the customer's side of the service.
Event 34: Date: 4/12/19 Gallons: 75
Location:
5426 Osage Court - sewer lateral in rear of property at drainage corridor
Description:
A plumbing company notified PWC of a service lateral blockage with potential damage to the lateral piping.
Upon PWC response and evaluation of the issue, it was determined that the City of Fayetteville storm drainage
installation project caused a separation of the service lateral from the sewer main. This resulted in a sewer
release during the plumber's attempts to clear the blockage.
Corrective Measures:
PWC on call personnel responded immediately to assist the plumber in evaluating the issue and providing a
temporary fix until a permanent, corrective action could be completed by the City's contractor. Due to conflicts
with the newly installed storm drainage, PWC staff installed a temporary holding tank immediately behind the
residence and implemented pump and haul measures The pump and haul system was in place until the
permanent repair could be completed by the City contractor.
Event 35: Date: 4/22/19 Gallons; 10,200
Location:
5350 Silver Pine Drive - manholes in easement area
Description:
This SSO was caused by vandalism of the sewer system. A manhole cover was removed and debris placed into
the manhole. The debris included logs, sticks, a cooler, and other miscellaneous trash.
Corrective Measures:
The sewer main was jet rodded to clear the blockage and end the spill incident. Manhole entry was performed
to remove the vandalism materials. Main cleaning and CCTV inspections to verify debris removal were
completed on 4/24/19. Locking rings and covers were installed on 4/22/19 to prevent access by the vandals.
The wastewater residue was removed from the spill location and the area treated with lime and odor
counteractant. A police report was completed and is on file.

Event 36: Date: 6/4/19 Gallons: 4
Location:
234 Green Street—manhole behind the church playground in creek bank
Description: This SSO was discovered during routine inspections of the collections system. It was identified
that wastewater was seeping thru the cracks in the manhole wall. The subject manhole and 18" aerial crossing
were structurally evaluated after Hurricane Matthew and Hurricane Florence. During the evaluations there was
creek bank erosion that was deemed to be significant enough to warrant replacement/relocation of the existing
manhole and aerial crossing. Engineering design has been completed and the preconstruction conference was
held on 6/5/19.
Corrective Measures:
PWC staff responded and sealed the leaking areas on the manhole. The seal was placed on the exterior and
interior of the manhole. No cleanup was required since the volume of the spill was so low.
Event 37: Date: 6/26/19 Gallons: 1,150
Location:
3609 Ridgecrest Avenue—manhole in the street
Description:
This SSO was caused by the bypass pump running out of fuel on a PWC sewer rehabilitation project. The
contractor was installing a liner in an 18"gravity sewer main. As part of the process a sewer bypass system was
set up to bypass flows from the smaller collector main and was being maintained by the contractor. During the
operation a contractor employee noticed sewer exiting from a manhole and immediately called the PWC project
coordinator over that project. .
Corrective Measures:
The contractor's staff responded to the SSO and began evaluating what had caused the over flow. It was
determined that the bypass pump had run out of fuel. Due to the pump being out of fuel the collection system
surcharged and a spill occurred. The contractor had the pump vendor send the fuel truck to the site to fuel the
pump back up. Once fueled the pump was started back up and the spill incident ended. The wastewater exiting
the manhole entered a nearby storm drainage system, which discharged into a wet drainage ditch. The
pavement area, curb line, and the affected storm drains were cleaned to remove wastewater residue. All liquid,
wastewater, and groundwater were vacuumed/reclaimed from the wet drainage ditch. Due to the natural
erosion of the drainage ditch a ponding area had been created in the channel allowing for full containment of the
wastewater.
