This study aims to evaluate the potential of constructed wetlands as systems for domestic wastewater treatment in Peru. A systematic review of the literature on constructed wetlands in Latin America and the Caribbean was made, where it was possible to select 170 articles and analyze 359 experiences developed in 16 countries of the region. Among, the main characteristics collected from the experiences, it was obtained that the most used treatment system is formed by “Septic tank and constructed wetlands“ (35 percent), while horizontal subsurface flow wetland is the most studied type (62 percent). In regards of the meta-analysis, the median COD removal efficiency is 70 percent, with a 95 percent confidence interval from 62 to 77 percent; while the median removal efficiency for both TN and TP were similar at 40 percent. Subsequently, from the subgroup analysis, it has been identified that climate is a variable that could affect the performance of constructed wetlands in the removal of organic matter, so they are more efficient in equatorial climates. Regarding the potential of constructed wetlands in Peru, there are legal figures that encourage the use of unconventional treatments; however, the lack of a technical standard specialized in constructed wetlands does not allow for greater dissemination among sanitation service providers. Fifty cases were analyzed in our country, that showed that the availability of macrophytes in natural ecosystems and trained human resources are not a technical factor that limits the application of this technology. Due to the lack of studies covering different seasonal periods, it was not possible to show the influence of climate on the efficiency of wetlands built for the removal of organic matter in peruvian cases.
