MOLINO_MALTIGNANO_MLT_DEP is a secondary wastewater treatment plant in Caselle, Marche, Italy, serving a small population of 71. It discharges 14.06 m³/day and operates under EU Urban Waste Water Treatment Directive standards.
MOLINO_MALTIGNANO_MLT_DEP is a secondary wastewater treatment plant located in Caselle, a locality in the municipality of Maltignano, Ascoli Piceno, Marche, Italy. The plant serves a small population of 71 and has a designed capacity of 100 m³/day, with a current discharge volume of 14.06 m³/day, indicating low utilization relative to capacity. As a secondary treatment facility, the plant provides biological treatment to reduce organic matter and suspended solids. It operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this scale. The plant's small population served places it in the category of smaller agglomerations, where secondary treatment is the standard requirement. The plant's treated effluent is discharged into local watercourses that drain into the Adriatic Sea via the Tronto River basin. The Marche region features a hilly terrain with rivers flowing eastward to the Adriatic. The plant's location more than 10 km from the coast reduces direct marine impact, but its discharge contributes to the overall water quality of the regional watershed.
Environmental context
The plant discharges into the Tronto River basin, which flows eastward through the Marche region into the Adriatic Sea. The downstream environment supports diverse aquatic life and is used for irrigation and recreation. The Adriatic Sea is a semi-enclosed basin with sensitive coastal ecosystems, including seagrass meadows and fish nursery areas, making nutrient and pollutant control important for maintaining ecological balance.
Frequently asked questions
The plant is located in Caselle, a locality in the municipality of Maltignano, in the province of Ascoli Piceno, Marche region, Italy. Its address is Via Mediana Superiore, Bonifica, Caselle.
The plant provides secondary treatment, which involves biological processes to remove organic matter and suspended solids from wastewater before discharge.
The treated effluent is discharged into local watercourses that are part of the Tronto River basin, which flows into the Adriatic Sea.
As a plant serving a small agglomeration of 71 people, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. Italy implements this directive through national regulations.
For small agglomerations under 2,000 population equivalent, the EU directive allows appropriate treatment, but secondary treatment is common. In Italy, such plants often use compact biological systems like activated sludge or sequencing batch reactors to meet effluent standards.
