About this file
This is an Operations and Maintenance Manual for the RV Sewer Dump Station located at Joint Base Charleston Short Stay Recreation Facility in Berkeley County, South Carolina. The manual, dated April 2, 2015, provides operational and maintenance guidance for a wastewater holding tank system consisting of two precast concrete tanks with a combined 15,000-gallon capacity. The system includes two 7,500-gallon tanks connected by a 24-inch equalizer pipe, with two manholes per tank. The high-level alarm activates at 75 percent capacity, approximately 11,800 gallons, with alarm activation occurring at 5.5 feet of liquid level.
The contractor's primary operational requirements include daily volume monitoring to determine when pump-out services are needed, monthly testing of the high-level alarm system, and comprehensive documentation of all inspections with date, time, volume measurements, and personnel names. The contractor must maintain holding tank volume below 9,000 gallons and perform pump, haul, and disposal services before reaching that threshold, providing certificates of disposal for each occurrence. Additional duties include keeping drain holes clean and rinsed using wash-down hydrants and ensuring tanks are pumped out prior to Memorial Day, Independence Day, and Labor Day. All inspection records must be maintained on-site throughout the contract period and transferred to the Government upon contract expiration. Facility contact information includes CE Customer Service (843-963-5027), JB CHS Environmental (843-963-1483), Short Stay Management (Mr. Richard Hahn, 843-761-8385), and Engineering Flight for construction matters (843-963-1493).
