Since the 1972 Clean Water Act PL 92-500, the definition of adequate and sustainable pollution treatment has changed. The old 30;30 discharge standard (30 mg/l ammonia and BOD) was not adequate to reach defined goals – fishable and swimmable – for all waters of the state. Since 1972, measured damage to a healthy fishery and community sustainable has changed waste water treatment strategies. Plants were not any part of the 1972 treatment design options. The criteria for successful design – feasible, practical, economical, safe, legal, moral, politically acceptable and ecological – will be used to compare modern alternatives now considered for large and small waste water sources.
