CONSUMPTION AND COST









Tertiary treatment is currently installed at the WWTP “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

1.2.a) y 4.1.

The technology used consists of physical-chemical sedimentation and filtration lamellar traveling bridge filter

cleaning continuously. Disinfection is accomplished with ultraviolet radiation and application of sodium hypochlorite.
