FUENTES PÚBLICAS

What public sources report

Population of the served area (Neuss-Ost): 84,295 inhabitants (2025, North Rhine-Westphalia environmental authority).

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 L06; it does not change the official data.
