Documented milestones

1987 · The Styrian register dates the commissioning of Wildon wastewater treatment plant to 1987. Government of Styria

Facts taken from public documents, with their date and link; an authorisation, a project or a planned capacity do not prove operation or quantities actually treated. Aguas SB editorial layer, lot L07; it does not change the official data.
