    How it works?



    Wastewater enters the treatment plant and immediately undergoes mechanical treatment.

    Anaerobic zone

    Then the water flows through the chamber
    biological treatment in an oxygen-free environment.


    Denitrification zone

    A mix of activated sludge and water flows evenly into this area to remove odors.


    Aeration zone

    Then, a mix of silt and water
    enters the camera of
    oxygen treatment


    Decantation zone

    At the end of the purification process, the water enters the decantation section, where, under the force of gravity, it is finally separated into water and sludge.

    After the completion of the cleaning process, the resulting water can be reused for watering plants, washing your car, etc.

    Why is it important?

    Currently in Spain, deaf wells are prohibited. The drainage system allows wastewater to enter the ground, that creating serious pollution problems. Authorities can sanction the person responsible for the spill with a fine of € 3,000 or more.

    “… as long as they are not connected to the appropriate public networks, the houses […] must have water treatment facilities or septic tanks, septic tanks with drainage and cesspools are prohibited.” BOE-A-2017-10295
