This paper presents a technology review in six countries of Latin America and the Caribbean (LAC) which are the result of the analysis taking into account a large number of flow ranges and types of treatment technologies. Additionally, the legislations of the countries of the region are analyzed. The most representative technologies according to the sample analyzed for LAC countries are stabilization ponds, activated sludge processes, upflow anaerobic sludge blanket reactors (UASB) and trickling filters, with an average flow capacity of; 13 l/s, 70 l/s, 618 l/s and 5,800 l/s, for the following arbitrary flow classification: 0-25 l/s, 25-250 l/s, 250- 2,500 l/s and >2,500 l/s respectively.

Keywords Wastewater, treatment technologies, Latin America.
