CRESPELLANO_VIA_LUNGA Wastewater Treatment Plant, Valsamoggia, Emilia-Romagna

CRESPELLANO_VIA_LUNGA is a municipal wastewater treatment plant located in the Crespellano district of Valsamoggia, in the Emilia-Romagna region of northern Italy. The plant serves a population of approximately 5,000 residents and has a designed capacity of 5,000 cubic meters per day, operating at near-full capacity with a reported discharge volume of 488.70 cubic meters per day. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring compliance with European effluent quality standards. The treated wastewater is discharged into the local drainage network, which ultimately flows into the Reno River. The Reno River runs through Emilia-Romagna and empties into the Adriatic Sea near the Po Delta. This discharge contributes to the river's flow and must meet regulatory limits to protect downstream aquatic ecosystems and coastal water quality.

The plant discharges into the Reno River basin, which drains the Apennine foothills and flows eastward to the Adriatic Sea. The Reno River supports diverse aquatic life and is used for irrigation and recreation. Downstream, the river enters the Po Delta region, an ecologically sensitive area with extensive wetlands and lagoons that provide critical habitat for migratory birds and fish species. Proper treatment is essential to prevent nutrient loading and protect these downstream environments.
