Overview
IDI_CUOIO_DEPUR is a major wastewater treatment plant serving San Miniato, Toscana, Italy. It handles a population equivalent of over 575,000, operating under EU Urban Waste Water Treatment Directive standards.
IDI_CUOIO_DEPUR is a large municipal wastewater treatment plant located in San Miniato, in the Toscana region of Italy. Serving a population equivalent of approximately 575,672, it is classified as a large agglomeration under EU regulations. The plant is situated near the Arno River basin, which drains into the Tyrrhenian Sea. As a facility of this scale, it is required to meet stringent treatment standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations over 150,000 population equivalent, the directive mandates secondary treatment as a minimum, with tertiary treatment required in sensitive areas. The plant's treatment processes are designed to comply with these regulations, ensuring effective removal of organic matter and nutrients. The treated effluent is discharged into the local water system, ultimately reaching the Arno River and then the Tyrrhenian Sea. This discharge must meet strict quality standards to protect the downstream aquatic environment, which supports diverse ecosystems and is important for regional biodiversity. The plant plays a critical role in safeguarding water quality in the densely populated and industrially active Toscana region.
Environmental context
The plant discharges into the Arno River basin, which flows through Toscana and empties into the Tyrrhenian Sea. The Arno River supports a variety of aquatic life and is ecologically sensitive due to historical pollution pressures. The downstream coastal area includes important habitats for marine species. Effective treatment at this plant is crucial for maintaining water quality in the river and the sea.
