Aguas Andinas has started work on two of the three well fields in its 2025–2030 programme, which together add 3,190–3,200 L/s of groundwater capacity for Santiago on published flows. By September 2026, the first four wells of the Santiago Poniente field had been drilled and construction of the Fajas de Canales wells had begun.
Where the work is
Santiago Poniente is planned as 12 wells producing 1,200 L/s. Its first stage of four wells adds 400 L/s from the last quarter of 2027, once a 5,000 m³ tank and a pumping plant are finished.
At Fajas de Canales in Calera de Tango, the company is building eight wells about 160 m deep with the Asociación de Canales del Maipo, giving 500 L/s according to a September 2026 press report. Its May 2026 presentation described the project as seven wells of 70 L/s each. A third field, Santiago South, is planned as 16 wells producing 1,500 L/s.
Why it is funded
The wells sit inside a CLP 365 billion tariff-linked investment plan for 2025–2030, and the company says its Biociudad projects are fully covered by approved tariffs. The base drought works, at 3.85% of the tariff, are the largest single item. Aguas Andinas invested CLP 91,614 million in the first half of 2026, up 27% on a year earlier.
What is not public
Neither field's contractor has been named in public sources. Tenders at Aguas Andinas have run on SAP Ariba since 2020, and engineering and consulting work requires accreditation that can take up to 20 business days.
