Impianto Consortile S. Agata C. da Inganno is a municipal wastewater treatment plant located in Sant'Agata di Militello, a town in the province of Messina, Sicily, Italy. The plant serves a population of approximately 27,277, classifying it as a medium-sized agglomeration under Italian and EU regulations. As a plant in Italy, it operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the discharge enters sensitive areas. The plant discharges into the local watershed, which ultimately drains into the Tyrrhenian Sea. This coastal environment supports diverse marine life and is an important ecological zone. The plant's proximity to the coast underscores the need for effective treatment to protect marine water quality and comply with EU standards for coastal discharges.

The plant is located near the Tyrrhenian Sea coast of Sicily, within the drainage basin of local streams that flow into the sea. The Tyrrhenian Sea is a semi-enclosed basin supporting diverse marine ecosystems, including seagrass meadows and fish nurseries. Effective wastewater treatment is critical to prevent nutrient enrichment and protect coastal water quality, which is vital for tourism and fisheries in the region.
