The improvement in sewage treatment technologies has been pivotal for many reasons: water reutilization prevents potential pollution issues, whilst being an invaluable source for irrigation in cultivation areas. Hence why WWTPs or waste water treatment plants play a key role in environmental protection projects.

But, what would happen if water treatment´s beneficial effects added up to those of renewable energies? That is the exact approach of Renewat, a pioneering project in Spain supported by ACCIONA Agua. Renewat integrates renewable sources such as wind or solar energy into the treatment process to achieve reduced consumption and CO₂ emissions into the atmosphere. An ambitious effort in which cooperation among the diverse energy-generating procedures is central, and is already paying off. Let´s dive into it.
