A two-phase program developed and demonstrated a new method for on-shore treatment of sewage from recreational watercraft. Phase I characterized wastes and chemical additives associated with recirculating/retention systems. Statistical analysis determined probable ranges of waste characteristics as a function of watercraft type and location. Typical wastes had suspended solids and biochemical oxygen demand of 2000 mg/l. Respirometer studies evaluated toxicity of additives to activated sludge. Treatability of chemical/sewage mixtures was determined from pilot-scale activated sludge plant operations. Cell yield coefficients were calculated. Photomicrographs recorded physical changes to activated sludge. Phase II field tested full-scale physical-chemical treatment equipment operating on watercraft wastes. Average removal efficiencies for suspended solids, biochemical and chemical oxygen demand, phosphate, and zinc were greater than 90 percent. Discharge solids were nonodorous and innocuous. Postchlorination increased total-nitrogen removal from 30 to 70 percent. Operating costs were determined.
