SURVEY, ANALYSIS AND EVALUATION OF DOMESTIC WASTEWATERS ON COAST GUARD VESSELS

Five Coast Guard cutters, ranging from a 82 foot, 8 man patrol boat to a 387 foot, 160 man high endurance cutter, were monitored for water consumption and wastewater flow and composition. Data was taken dockside and underway, and the waste water was segmented into sanitary, galley, and turbid system. Crew size and flow were monitored in half hour time blocks, and used to reduce actual flow data to a pre-man basis. As the ships did not have full crews on board during the sampling periods, flow volume was also normalized to full crew size. Wide variation was found, with no consistency in the data when analyzed for crew size, dockside versus underway to operation, or type of operation (patrol vs. buoy tending). Standard deviations of means were very large, an indication that the ships do not represent a regular population of data. Flow and composition also varied greatly through the day. The report contains 81 plots (each with a separate plot for each ship), showing flow and chemical parameters for the three sanitary systems, for dockside and underway, by time of day. Other plots show crew size, saltwater usage and freshwater usage. (Author)
