Overview
Trevi Pietrarossa wastewater treatment plant serves Santa Maria in Valle, Umbria, Italy, with a population equivalent of 7,766. It operates under the EU Urban Waste Water Treatment Directive.
The Trevi Pietrarossa wastewater treatment plant is located in Santa Maria in Valle, a frazione of Trevi in the Umbria region of central Italy. Serving a population equivalent of 7,766, the plant is part of the municipal wastewater infrastructure for the Trevi area, situated in the Apennine foothills. As a medium-sized agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC), the plant is expected to provide at least secondary treatment. Italian regulations transpose this directive, and plants of this scale typically employ biological treatment processes to meet effluent standards before discharge. The plant's treated effluent likely discharges into a local watercourse that feeds into the Tiber River basin, which flows through Umbria and Lazio to the Tyrrhenian Sea. The Tiber basin supports diverse aquatic life and is an important water resource for central Italy.
Environmental context
The plant's receiving water body is likely a tributary of the Tiber River, which flows through Umbria and Lazio before entering the Tyrrhenian Sea near Rome. The Tiber basin is ecologically significant, supporting fish species such as the Tiber barbel and providing habitat for migratory birds. Downstream waters are used for irrigation and drinking water supply, making nutrient removal important for preventing eutrophication.

The plant serves a population equivalent of 7,766 people, classifying it as a medium-sized agglomeration under the EU Urban Waste Water Treatment Directive.
The treated effluent is likely discharged into a local watercourse that flows into the Tiber River basin, eventually reaching the Tyrrhenian Sea.
The plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), transposed into Italian law. This directive requires secondary treatment for agglomerations of this size, with possible additional nutrient removal if discharging into sensitive areas.
For medium-sized agglomerations in Italy, typical treatment includes primary sedimentation followed by biological secondary treatment, such as activated sludge or trickling filters. This meets the EU directive's requirements for organic matter and suspended solids removal.
