Penobscot Bay's sewage plants dump 2.4 billion gallons of treated wastewater into the bay every year

What do the people of Rockland, Camden, Belfast, Searsport, Castine, Islesboro and North Haven have in common? Our sewage treatment plants discharge about 6.5 million gallons of treated wastewater into the bay per day, or 2.4 billion gallons per year. 

Operating a sewage treatment plant is both an exacting technological process and a demanding art. Maine DEP monitors the outfall reports from these operations, praising those which stay within their discharge limits and prodding those that don't into bettering their ways. 

Here are  links to each of these towns' most recent DEP wastewater treatment licences and their DEP ID numbers
