The plant provides secondary treatment, a standard level for small communities in the United States, and operates under the regulatory framework of the Clean Water Act, which requires NPDES permits for discharges to surface waters. The plant has a designed capacity of 1,476.31 volume units and currently handles a discharge volume of 571.60 units, indicating operational capacity well within its design limits. As a secondary treatment facility, it employs biological processes to reduce organic matter and suspended solids before discharge. The treated effluent from MILO WWTF is released into the local watershed, which ultimately drains into the Penobscot River and then to Penobscot Bay in the Gulf of Maine. The receiving waters support diverse aquatic life and are important for regional fisheries and recreation. The plant's operation helps protect downstream water quality in this ecologically sensitive area.

The plant discharges into the Penobscot River watershed, which flows into Penobscot Bay and the Gulf of Maine. This region supports critical fish habitats, including Atlantic salmon and brook trout, and is influenced by tidal dynamics. The secondary treatment provided by MILO WWTF helps reduce nutrient and pollutant loads, protecting the downstream estuarine and marine ecosystems.
