Overview
SALETTE wastewater treatment plant serves Sperlonga, Lazio, Italy, with a population equivalent of 28,000. It has a designed capacity of 1.00 and is located within 50 km of the coast.
SALETTE is a wastewater treatment plant located in Sperlonga, a coastal town in the Lazio region of Italy. The plant serves a population equivalent of approximately 28,000 people, placing it in the medium agglomeration category under Italian and EU regulations. Its location near the Tyrrhenian Sea makes it part of Italy's coastal wastewater infrastructure. As an Italian plant, SALETTE operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size discharging into coastal waters. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The treated effluent from SALETTE ultimately discharges into the Tyrrhenian Sea, a major basin of the Mediterranean Sea. This coastal environment supports diverse marine life, including seagrass meadows and fish populations. Proper treatment is essential to protect bathing waters and marine ecosystems along the Lazio coast, which are important for tourism and local fisheries.
Environmental context
The plant discharges into the Tyrrhenian Sea, part of the Mediterranean Sea, which is a semi-enclosed sea with limited water exchange. The coastal waters near Sperlonga support ecologically sensitive habitats, including Posidonia oceanica seagrass meadows, which are vital for biodiversity and coastal protection. Nutrient inputs from wastewater must be carefully managed to prevent eutrophication and maintain water quality for tourism and marine life.

As an Italian wastewater treatment plant, SALETTE operates under the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive requires secondary treatment for agglomerations of 10,000-150,000 population equivalent discharging into coastal waters, with possible tertiary treatment if the receiving area is sensitive.
Under the EU Urban Waste Water Treatment Directive, plants serving agglomerations of 10,000 to 150,000 population equivalent are required to provide at least secondary treatment (biological treatment). For coastal discharges, this is the standard requirement unless the receiving waters are designated as sensitive areas, which may necessitate more advanced treatment.
