The Rise of Chemical-Free Water in Argentina

Cost pressures and water stress are driving interest in chemical-free systems that reduce maintenance risk and improve long-term efficiency in select projects

2 Feb 2026

A small but growing number of developers and facility managers in Argentina are turning to chemical-free water treatment systems, as pressure mounts to reduce operating costs and manage water more efficiently.

Instead of relying on chemical additives and frequent maintenance, the systems aim to limit mineral build-up in pipes and equipment through physical processes. Proponents say this can extend asset life and lower energy use, shifting how water infrastructure is assessed, from a fixed utility cost to a long-term efficiency consideration.

Aquanex, a local provider, has recently expanded beyond heavy industrial clients into residential and mixed-use buildings. The move reflects wider interest in applying technologies traditionally used in large facilities to smaller, everyday developments. While adoption remains limited to selected projects, developers say the approach is attracting attention where long-term operating costs are a concern.

The underlying technology is supplied by Swiss Aqua Technologies, whose systems are designed to change how minerals behave in water rather than removing them with chemicals. Supporters argue that the appeal is less about technical detail and more about outcomes, such as reduced downtime, cleaner systems and lower maintenance bills over time.

“This is about rethinking water from a long-term cost perspective,” said a regional water management consultant familiar with the projects. “When scale builds up, systems work harder and wear out faster. Preventing that upfront can translate into savings year after year.”

Local conditions are adding to the interest. Argentina faces water stress in several regions, while energy prices and maintenance costs remain volatile. At the same time, investors and tenants are paying closer attention to sustainability measures and operational resilience. Buildings that can demonstrate lower chemical use and more efficient water management are increasingly seen as better positioned over the life of an asset.

Scepticism remains among some engineers, particularly those accustomed to established chemical treatments. Performance can also vary depending on water quality and local conditions, limiting the scope for uniform adoption. Independent data on nationwide use are scarce.

Industry observers say the shift is likely to remain gradual. Rather than replacing conventional systems outright, chemical-free treatment is being tested as part of a broader effort to manage costs and reduce risk in Argentina’s water sector.
