Canal de Isabel II, Madrid, awarded Sacyr Agua the operations and maintenance contract for the La Gavia water treatment plant. The plant treats up to 172,800 cubic meters of water a day from two collectors (Gavia I and Gavia II) and the excess flow from the La China WWTP.
The plant uses tertiary treatment to convert all of its treated water into regenerated water, so that excellent quality water can be returned to the Manzanares river. Part of the water is reused to irrigate green spaces, for street cleaning and for golf course hazards.
The infrastructure includes facilities to produce green power from the liquid waste generated by citizens, which is treated and then converted into biogas.
The facility has a gas station to refuel vehicles that run on renewable biogas.
The bidding process included criteria such as using vehicles with a reduced carbon footprint, reducing the sound level of industrial vehicles, and guaranteeing that samples taken from the water line would be retained.
