DP02005002_RIVAROLO_MANTOVANO Wastewater Treatment Plant, Rivarolo Mantovano, Lombardy

DP02005002_RIVAROLO_MANTOVANO is an advanced wastewater treatment plant located in Rivarolo Mantovano, a town in the province of Mantua, Lombardy, Italy. The plant serves a population of about 2,773 and has a designed capacity of 3,000 cubic meters per day, with a discharge volume of 548.96 cubic meters per day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for plants discharging into sensitive areas under the EU Urban Waste Water Treatment Directive (91/271/EEC). Italy implements this directive through national regulations, requiring advanced treatment for agglomerations above 10,000 population equivalent in sensitive catchments, though smaller plants may also adopt advanced processes to protect local water quality. The plant discharges into the local water network, which ultimately drains into the Po River basin, the largest river system in Italy. The Po River flows eastward into the Adriatic Sea, supporting extensive agricultural activity and diverse ecosystems. The advanced treatment helps reduce nutrient loading, mitigating eutrophication risks in the Adriatic Sea and protecting downstream aquatic habitats.

The plant is situated inland in the Po River basin, a major agricultural and industrial region. Treated effluent likely enters local canals or tributaries that feed the Po River, which discharges into the Adriatic Sea. The Po delta is an ecologically sensitive area supporting migratory birds and fish species. Advanced treatment at this plant helps control nutrient pollution, reducing the risk of algal blooms and oxygen depletion in downstream waters.
