Impianto CDA Mangiasalsiccia - Primary Wastewater Treatment Plant in Aliminusa, Sicily

Impianto CDA Mangiasalsiccia is a wastewater treatment plant located in Aliminusa, a municipality in the province of Palermo, Sicily, Italy. The plant serves a population of approximately 1,637 people and has a designed capacity of 2,000 cubic meters per day, with an average discharge volume of 324.07 cubic meters per day. As a primary treatment facility, the plant provides basic physical treatment such as sedimentation to remove settleable solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent (PE) between 2,000 and 10,000 are generally required to have secondary treatment. However, primary treatment may be acceptable for discharges to coastal waters under certain conditions, subject to a case-by-case assessment. The plant is located within 10 km of the coast, indicating that treated effluent likely discharges into the Tyrrhenian Sea or a nearby coastal water body. This proximity to the marine environment underscores the importance of effective treatment to protect coastal water quality and marine ecosystems. The plant's operation contributes to the management of wastewater in the region, supporting public health and environmental protection.

The plant is situated near the northern coast of Sicily, within the Tyrrhenian Sea basin. Treated wastewater likely discharges into a coastal water body that flows into the Tyrrhenian Sea, a part of the Mediterranean Sea. The coastal waters in this area support diverse marine life, including seagrass meadows and fish populations, and are important for local fisheries and tourism. Effective treatment is essential to minimize nutrient and pollutant loads that could cause eutrophication or harm sensitive marine habitats.
