In Catalonia, Veolia says it is strengthening environmental security through water management projects in municipalities including Sabadell, Rubí, Palamós, Blanes and Lloret. The company links this work to World Environment Day and its theme, “For Climate Now”, which focuses on climate action through mitigation and adaptation.
Veolia says its approach centres on the integrated water cycle, with a focus on decarbonising services, decontaminating resources and increasing reuse. It says digital tools and sustainable solutions are being used to improve resource management, reduce the environmental impact of infrastructure and support Catalonia’s ecological transition.
The company describes environmental security as the ability to keep water and other essential resources available and in good condition for daily life, even in difficult conditions. It says this also matters for agriculture, food production, industry and public services. Veolia adds that it aims to keep services running during heatwaves and flood risks.
On carbon reduction, Veolia says it is using energy efficiency measures, waste valorisation, resource recovery from wastewater treatment and local renewable energy production. In 2025, it says it generated 14.7 million kWh/year of electricity from renewable sources in Catalonia, mainly through biogas cogeneration at wastewater treatment plants and solar photovoltaic installations. It says this avoided 3,801 tonnes of carbon dioxide, equivalent to the absorption of 2,091 trees.
The company also says it improved four biogas cogeneration systems at wastewater treatment plants in Sabadell Riu Ripoll, Palamós, Blanes and Lloret, with expected extra production of 1.3 GWh/year. It says nine new photovoltaic installations, with a total power of 418 kW, were launched in 2025, along with a 3 kW wind turbine. Veolia says it now manages 75 renewable energy generation installations in Catalonia’s water sector, and that its fleet includes 145 electric vehicles.
For climate adaptation, Veolia says it is working on water regeneration, reuse and infrastructure resilience. It points to PERTE projects for the digitalisation of the integrated water cycle, as well as A-MEDI projects in eight Catalan coastal municipalities, e-READAPTA in Rubí and FLOW in Sabadell. In Sabadell, it says plans are in place to replace 20% of annual potable water use with phreatic water from local wells and mines, plus regenerated water. More Catalonia news
Veolia says the A-MEDI work includes multiparametric analysers with conductivity sensors to monitor water quality in headwater reservoirs, while network sectorisation is expected to reduce losses by about 6%. In Rubí, it says four water intakes are being activated and sensor systems installed to recover resources from the Vallès aquifer. It also says the e-READAPTA project is designed to improve resilience to heavy rainfall through an emergency flood plan, continuous monitoring and retention measures at critical discharge points.
