This inspection was conducted in response to a recent moratorium initiated due to flows exceeding 80% of design capacity of the WWTP. Jonathan Cannon and Kevin Queen (Saluda), Bobby Kramer (KACE) were present and assisted in the inspection. Staff are working to maintain the system in compliance; however, aging infrastructure is causing significant I&I within the collection system. Improvements included as part of the USDA loan are in the process of being completed, but were not significant sources of I&I. All LS appear to be in operable condition. Quick connects are recommended on stations without current power reliability. Forest Creek LS: Generator on-site; however, needs new circuit board. Minimal flow at facility (currently one or two houses connected). Has auto-dialer, but not connected. Facility is checked daily. Truck Stop LS: New panel box is ready to be installed and has SCADA capability. Force main is going to be replaced. Failing concrete lining inside of ductile iron has constricted flow causing issues at the LS. City staff are pumping LS regularly to maintain an appropriate level until repairs can be made. Two new pumps installed and the lag float is being replaced. Generator was tested during the site visit and appeared to be working adequately. Laurel Dr. LS: Staff are working on getting a quick connect for the LS. 176 LS: Components for the new LS are installed. The older chambered LS is still in use until power is run to the booster station. Potentially on-site generator if funding allows. Currently there is no on-site generator. A UT to Joels Creek increases flows into one of the system's main terracotta lines under Main St. during heavy rains. Several issues appear to be contributing to continued degradation of the infrastructure. Part of this line has been slip-lined in the past; however, continued ground movement around the line has caused joints to further separate. Due to the shifting joints and instability of the surrounding soils, slip lining does not seem practical. Additionally, DOT stormwater culverts intersect with the flow of the UT and the main sewer line through Town, creating additional structural concerns. Sink holes continue to occur. Much of the line parallels the stream bank and will require acquisition of easements for a full repair. As discussed during the site visit, the City should continue to work with their contracted engineer to prioritize which lines may be the most significant contributors to I&I and create an new extended capital improvements plan. Please reference the sewer-line moratorium letter dated October 21, 2019 to determine what immediate steps need to be taken to return to compliance with 15A NCAC 02T.0118.

Is there a overall sewer system map? Does the map include: Pipe sizes Pipe materials (PVC, DIP, etc) Pipe location # Flow direction # Approximate pipe age # Pump station ID, location and capacity # Force main air release valve location & type # Location of satellite connections Are system maintenance records maintained? This is a deemed collection system. Facility map was not reviewed during this site visit. This visit was to discuss the status of the current infrastructure and current plans moving forward to repair issues discussed during the CEI in April. All sewer system informaiton is being maintained in a gis program. Air relief valves were recently located and are in the process of being repaired. See summary for inspection observations and recommendations.
