Pig farms with 100,000 animals produce the waste of a city of a quarter-million people, but have no wastewater treatment system. At a single site in Missouri, one pig factory produces fecal waste equivalent to that of a city of 360,000. There are wastes in addition to manure. According to one industry journal, "a 5000 sow farrow-to-finish farming system with a mortality of 7%, 10%, 5%, 1% and 1% in the sow, neonatal, nursery, growing, and finishing herd, respectively, will produce in one year over 200,000 pounds of dead pigs."
