SUBJECT: Compliance Inspection Report
Lumberton Collection System
Collection System Permit No. WQCS00024
Robeson County
Dear Permittee:
The North Carolina Division of Water Resources conducted an inspection of the Lumberton Collection
System on 7/01/2020. This inspection was conducted to verify that the facility is operating in
compliance with the conditions and limitations specified in Collection System Permit No. WQCS00024.
The findings and comments noted during this inspection are provided in the enclosed copy of the
inspection report entitled "Compliance Inspection Report". There were no significant issues or findings noted
during the inspection and therefore, a response to this inspection report is not required.
All relevant records, including maintenance records, the current permit for the collection system, the Capital
Improvement Plan, sewer use ordinance, spill response plan, and a detailed digital map of the collection
system were available for review. Records and logs were well -organized. Pump station inspection records
were reviewed on site at pump stations visited during the inspections. The FOG control program is well -
enforced. Staff provided documentation of regular visits to businesses to along with follow-ups with violators.
Grease education materials are distributed via mailers once per year along with informational booths at
events like county fairs. The Capital Improvement Plan has a separate section for wastewater that extends
until 2025. While the Annual Wastewater Report is available at Town Hall please consider making it available
to customers through an annual mailer. The system map is current as of July 2020. In 2019, only 29,122 ft.
of the required 80,000 ft. of gravity sewer lines were cleaned; however, the system has undergone
significant refurbishment and the 10% minimum is typically met annually. It is strongly recommended that
technician Brian Connor pursue additional collection system operator levels as he is critical to daily lift station
operations.
Two high -priority (aerial) lines and three total right-of-ways were inspected. The high -priority lines
appeared to be in good condition. All areas were free of large debris and could be easily accessed during an

emergency. High -priority line inspections are documented every 3-6 months. Ten of forty-seven pump
stations were inspected. Water level at all pump stations is monitored with ultrasonic sensors. Note that the
simplex pump station is on SCADA. The single pump station that is not on the SCADA system served a
defunct business, and as a result, receives no wastewater flow. The station is still inspected weekly
although it is not in service. Comprehensive maintenance logs for pump stations were stored on site at the
stations. The inside and outside of stations were clean and well -organized. SCADA, audio, and visual alarms
worked properly for the majority of pump stations. Permanent generators are tested under load on a
biweekly basis. The issues identified at pump stations were: a malfunctioning visual alarm at PS 13,
generator starting under load but losing power at PS 51, generator not transferring power to pumps at PS
52, and a missing station identification sign at PS 59. Staff identified the sources of issues uncovered during
the inspection and will repair deficiencies as soon as possible.
If you should have any questions, please do not hesitate to contact Stephanie Zorio with the Water
Quality Regional Operations Section in the Fayetteville Regional Office at 910-433-3300 or via email at
