A sewer system was designed for Camp Challenge of the Florida Easter Seal Society, in Mount Plymouth, Florida, of polyvinyl chloride piping. Invert elevations were tabulized and necessary fittings determined for the system. Cost estimates were also included. The sewers were designed on a per fixture basis so as not to overdesign using per capita flow rates. A literature and records search was conducted to obtain design and actual wastewater flow quantities in gallons per capita per day (gpcd). Actual flows determined from 4 camps and 11 travel trailer parks gave average values of 39 and 33 gpcd, respectively, and can be used as design parameters for wastewater treatment facilities. However, further investigations and intensive flow monitoring are deemed necessary to provide a wider, more accurate data base with less variability.
