Situated on 288 acres, Southerly is the largest of NEORSD’s three wastewater plants, and one of the largest facilities of its kind in the country. The first-stage activated-sludge process is like those used at Easterly and many other treatment plants around the world. The second-stage process uses specialized bacteria to remove ammonia and nitrogen, two compounds which deplete oxygen in receiving waters. As a final step, the flow passes through filters and is disinfected by a chlorination/dechlorination process from May to October.
