New wastewater treatment plants for Lisbon

A scheme to develop wastewater treatment facilities in the Lisbon region of Portugal looks set to benefit 325 000 residents. The investment pays for the two wastewater treatment plants, the construction and refurbishment of several pumping stations, and the laying of about 35 km of drainage pipeline.

Additional tools


The project covers the municipalities of Barreiro, Moita and Seixal and aims to improve the quality of wastewater that is discharged into the nearby Tagus Estuary.

One of the treatment plants serves Barriero/Moita and has been designed to deal with wastewater volumes of 294 000 hab.eq (i.e.: habitant equivalents, a unit of measure to explain pollution loads produced by the local population during a 24 hour period), at an average flow of 64 790 m³/day.

Treatment includes a disinfection process that harnesses ultraviolet radiation. Subsystems for this plant include: eight new pumping stations; the refurbishment of five existing pumping stations; and construction of about 25 km of pipeline.

The plant at Seixal has the capacity to treat 155 000 hab.eq with an average flow of 42 050 m³/day. It also harnesses ultraviolet radiation as part of the disinfection process. Subsystems for this plant include: four new pumping stations; the refurbishment of two pumping stations; and the construction of about 10 km of pipeline.

The infrastructure is managed by Simarsul, a public enterprise. The project is expected to generate 21 jobs.

Total investment and EU funding

Total investment for the project “Simarsul” is EUR 61 239 784, with the EU’s Cohesion Fund contributing EUR 22 184 783 through the “Territorial Enhancement” Operational Programme for the 2007-2013 programming period, under the “Prevention, Management and Monitoring of Natural and Technological Risks” priority.
