In a clear commitment to energy efficiency and sustainability, several wastewater treatment plants (WWTPs) have begun to take advantage of solar energy by installing made-to-measure photovoltaic panels designed especially for Sorigué’s hydraulic engineering equipment. This first step paves the way to a new business niche for the business group to respond to the ever-growing market need for sustainable energy solutions with minimal environmental impact, such as in the hydraulic infrastructure sector. 
 
The first experiment was carried out at the Cunit-Cubelles WWTP with a design flow of 16,250 m³/day. With an infrastructure that meets the needs of the 81,250 inhabitants, this treatment plant has equipped its facilities with a renewable energy generation system using 38.74 kWp photovoltaic panels. 

 

In this way, an average annual consumption of 1,071,863 kWh of clean energy is guaranteed, in other words, 89.322 kWh per month. In addition, the electrical and control systems have been updated to optimise energy efficiency across the plant. 
 
The success of this project and the intention to continue with energy optimisation processes will lead Sorigué's hydraulic engineering team to the Vall d'Aran WWTP where the installation of new solar panels is planned for the end of 2021. 
 
Committed to its responsible business strategy, the Sorigué group is confident that these first actions in WWTPs will mark a turning point in the search for sustainable energy alternatives in the hydraulic infrastructure sector.
