Evacuación de aguas residuales
Division 370 of the classification the tax register files firms under, and the one activity inside it. 6,215 formal workers in 613 firms in 2024, across 113 communes.
The register files a firm at its tax address, so this is where the work is declared, not where it happens. The names are the SII's own, in Spanish, on both editions of this site: they are the wording a firm is filed under, not prose to translate.
Twenty years
2005–2024The whole series, not two ends of it: a division that halved over twenty years and one that halved last year give the same percentage, and only the line tells them apart.

Sales are not on this page. At this depth the SII withholds them in three of every four commune cells — a comuna where one firm would be the figure — so a map of sales would be a map of where the source happened not to withhold. Firms and workers are published everywhere and reconcile to the unit against the register's own national total. The checks are here.
