A consortium comprised of firms Aegea, Perfin and Kinea has won the privatization auction of a Companhia Riograndense de Saneamento (Corsan) in the southern state of Rio Grande, Brazil. 

Corsan provides water and wastewater services for the southern state of Rio Grande. At the privatization auction, Aegea, backed by Government of Singapore Investment Corporation (GIC) and Itausa SA, offered BRL4.15 billion (US$784.22 million) for Corsan. Aegea's bid was 1.15% higher than the minimum bid (US$1 = BRL5.2919).

Winning the Aegea auction was a step forward in the privatization of sanitation in the Latin American economy. In 2020, Congress approved a new framework for sanitation to attract investors from states and municipalities selling water and sanitation firms.
