Lantania Kicks Off Upgrade To Vila-Rodona's Sanitation System And New Wastewater Treatment Plant

Promoted and financed by the Catalan Water Agency (ACA), the project involves an investment of €4.4M

Lantania has kicked off work to improve the sanitation system and build the new wastewater treatment plant in Vila-rodona, Tarragona. Promoted and funded by the Catalan Water Agency (ACA), the project will be delivered by the infrastructure, water and energy group in partnership with Romà Infraestructures. The €4.4M contract (excluding taxes) runs for 12 months of construction, followed by three months of testing and a further 12 months of operation.

The new plant is designed to handle 410 m³ of wastewater a day using a biological process that reduces nitrogen, treating water for 2,400 residents. The cleaned water will flow back into the Gaià River, helping to improve its environmental health. Sludge will be managed through a rhizocomposting system that combines drying and stabilisation, using planted reeds to do the job naturally.

The project includes laying a collector over 500 metres long to bring wastewater from the town’s sewers. A new pumping station (EBAR) will also be built to push the water to the treatment plant through a delivery pipe sized to manage three times the normal flow, allowing it to handle some rainwater as well.

Work officially began with a groundbreaking ceremony led by Silvia Paneque y Sureda, Catalonia’s councillor for Territory, Housing and Ecological Transition, and attended by ACA director Josep Lluís Armenter, among other officials. They were joined by Antoni Solé, Lantania’s regional delegate for the north and east, and Victor Arcos, the company’s group head.

The new plant will bring Vila-rodona’s wastewater treatment up to current environmental standards and help protect the Gaià River ecosystem. It’s part of the ACA’s wider push to modernise sanitation across Catalonia and keep the water cycle running efficiently and sustainably.
