Overdue customer debt at Aguas Andinas reached CLP 98,859 million at the end of 2025, up 11% from CLP 89,169 million a year earlier, according to the company's 2025 integrated report and data tables. Over the same year, the number of customers in arrears fell from 271,784 to 244,369.
Debt concentrated in fewer accounts
The two figures point in different directions: the debt pool grew while the number of late payers shrank, so more debt now sits with fewer accounts. The wider group served 2,388,110 drinking water customers across Greater Santiago in June 2026.
