Abstract The efficiency of removal of organic load, nutrients and microorganisms present in the domestic wastewater of an indigenous community of La Guajira Colombia, in an integrated treatment pilot system whose configuration consists of two biodigesters connected to a biofilter module with subsurface vertical flow planted with macrophytes, with average efficiencies of 50.79% SST, 92.31% BOD5, 90.20% N and 56.87% P, which comply with the regulations, being a sustainable option for environmental management of water pollution in small communities. Keywords: Water pollution, biological treatment, environmental management 1. Introduction The environmental management of wastewater treatment is a priority issue worldwide, for the need to have water resources in sufficient quality and quantity,
