Metadata Sub-indicator 6.3.1.1. Porcentaje de carga contaminante total española correspondiente a poblaciones mayores de 2000 habitantes equivalentes que depuran adecuadamente las aguas residuales urbanas de acuerdo con el Art.4 de la Directiva 91/271/CEE sobre aguas residuales urbanas

Goal

Goal 6. Ensure availability and sustainable management of water and sanitation for all

Target

Target 6.3. By 2030, improve water quality by reducing pollution, eliminating dumping and minimizing release of hazardous chemicals and materials, halving the proportion of untreated wastewater and substantially increasing recycling and safe reuse globally.

Indicator

Indicator 6.3.1. Proportion of wastewater safely treated

Sub-indicator

Sub-indicator 6.3.1.1. Spain's total percentage for pollutant load in towns with more than 2000 inhabitants with an adequate urban waste water treatment system in accordance with Article 4 of the Directive 91/271/CEE

Type of indicator (global, European, national)
  • Global (proxy)
Definition

Porcentaje de la población equivalente de aglomeraciones urbanas mayores de 2.000 habitantes equivalente en el territorio nacional que se someten a un tratamiento secundario o equivalente al secundario, y cumplen con los requerimientos de la Parte B del Anejo I de la Directiva 91/271/CEE en cuanto a eliminación de materia orgánica y sólidos en suspensión.

Calculation method

\[PCC_{Depuracion, >2000 hab.}^t=\frac{PEQ_{Depuracion, >2000 hab.}^t}{PEQ_{>2000 hab.}^{t}} \cdot 100 \]Where: \( PEQ_{Depuracion, >2000 hab.}^t\)is the equivalent population of populations over 2000 hab-eq with adequate purification in year t and \( PEQ_{Colectores, >2000 hab.}^t\)is the total equivalent population of populations over 2,000 hab-eq in year t.
