What public sources report

Documented milestones

1980 · The municipal wastewater plan records 1980 as the construction year of Mõrra wastewater treatment plant in Pärnu. City of Pärnu

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.
