Findings during the inspection were as follows: 1. Carolina Water Service, Inc. of North Carolina holds a deemed sewer collection system permit and pursuant to 15A NCAC 02T .0403 that collects wastewater from nearby subdivisions for treatment at the Ashley Hill WWTP. 2. The collection system includes five duplex pump stations, approximately 10.1 miles of gravity sewer line, approximately 2.7 miles of force main, and one high priority line. 3. Five pump stations were inspected: Ruthledge Landing, Amber Acres, Amber Ridge, Bishop Point !3 and Bishop Point #2. All pump stations are identified with signs, secured access, and audible/visual alarms. The visual and audible alarms functioned when the high-water floats were activated, and the SCADA system acknowledged the alarms. All pump station had a generator on-site except for Bishop Point #1. The four on-site generators were operational and are tested every week. 4. The aerial high priority line was inspected at Amber Ridge, and it appeared straight, rust free and in good condition. The right of way (ROW) was adequately maintained, and a logbook is kept for inspecting the aerial high priority line and maintaining the ROW. 5. An overflow response plan is available in case of a failure at a pump station is developed and implemented. 6. An operation and maintenance plan including pump station inspection frequency and a preventive maintenance schedule is developed and implemented.
