Torredembarra Sewerage System

This sewerage system collects wastewater from the urban centres of Roda de Bara, Creixell and Torredembarra through the use of six pumping stations and 16 km of upstream pipe network

The sewerage network includes two sea outfalls for the emergency evacuation of rainwater discharges during heavy rainfall events.

The WWTP treats 8,400 m³ of wastewater daily through two treatment lines, each made up of a primary decanter 24 m in diameter, a 3,350 m³ bioreactor, and a 22 m secondary decanter.

The water treated is discharged into the sea through a 5 km sea outfall. The sludge line consists of two sludge thickeners and two centrifugal dewatering systems.

El Pla de Santa Maria System

The El Pla de Santa Maria WWTP treats 450 m3 of wastewater daily, which is transported to the plant via a 2.8 km gravity pipeline. The system consists of a dual activated sludge bioreactor line with a nutrient removal capacity of 745 m³, two secondary settlers, a dynamic sludge thickener, and dewatering.
