SOLIVELLA Wastewater Treatment Plant, Solivella, Catalunya

The SOLIVELLA wastewater treatment plant is located in Solivella, a municipality in the Conca de Barberà region of Tarragona, Catalunya, Spain. It serves a small population of 326 residents, reflecting its role in a rural or semi-rural community. The plant is situated near the Pont del Barranc del Xano and operates under Spain's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). As an advanced treatment facility, SOLIVELLA goes beyond the secondary treatment standard required by the EU directive for agglomerations of this size. The plant has a designed capacity of 2,462 cubic meters per day, though actual discharge volume is 125.68 cubic meters, indicating low utilization relative to capacity. This suggests the plant is well-sized for future growth or seasonal variations. The treated effluent is discharged into a local watercourse, likely a tributary of the Francolí River or the Gaià River, which flow toward the Mediterranean Sea. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports water quality in the region, which is part of the Ebro River basin district. The facility contributes to maintaining the ecological health of local streams and the broader coastal environment.

The plant discharges into a local stream within the Francolí River basin, which flows into the Mediterranean Sea near Tarragona. This coastal region supports diverse marine life and is an important area for fisheries and tourism. Advanced treatment at SOLIVELLA reduces nutrient loads and pollutants, helping to prevent eutrophication and protect sensitive coastal habitats in the western Mediterranean.
