AND DESCRIPTION OFTHETERTIARYTREATMENT
31. Tertiary treatment is currently installed at theWWTP “Peñón del Cuervo" produces a total of 2,616 m3/day of
reclaimed water for irrigation of urban green areas (point 1.2 of RD 1620/2007) and irrigation of golf courses (Point
4.1. the RD 1620/2007).
The reclaimed water perfectly fulfills the quality criteria according to Royal Decree 1620/2007 for applications
