Broad incumbents

• SABESP: Brazil's largest state-level water and sewage utility. Large-scale Latin American water utility with comparable potabilization, distribution, and sewage treatment operations under regulatory oversight — a useful scale and capex comparator.
• Veolia Water Technologies & Outsourcing: Global water services and technology major. Comparable in trenchless rehabilitation, SCADA/automation, and treatment-plant operating partnerships; AYSAM is a potential customer or partner for advanced treatment technology.
• SAUR (Suez group): French water-services operator with historical Argentine involvement (was part of the 1998 AYSAM privatization consortium). Operates and contracts on water and wastewater infrastructure globally, providing a benchmark for utility services outsourcing and concessions.

Others

Regional players

• Aguas Andinas: Chilean water utility serving Santiago. Closest geographic and climatic comparator in the Southern Cone, with similar semi-arid supply conditions and concession-based regulatory regime.

Most direct Argentine peer, operating under a similar federal/provincial concession framework with comparable potabilization and sewage treatment mandates.
