The following thesis was raised in order to verify the efficiency of an imhoff-HA tank as part of the improvement of municipal wastewater treatment, in this case the district of Havana. For which two experimental units were implemented; the first unit was an imhoff tank with 1.48 m long, 1.13 m wide and 1.02 m deep and the second unit of an artificial wetland with horizontal subsurface flow 1.83 m long, 0.77 m wide, 0.57 deep and slope of 1%, seeded with Phragmites australis (reed), 5.0 cm diameter gravel was used as the granular medium of the wetland. The study was started in the field, with the construction of the experimental units; operation, monitoring, location and sampling at the entrance of the residual water from the imhoff tank (tributary), entry to the artificial wetland (effluent 1) and exit of the residual water from the artificial wetland (effluent 2), to later pass to an analysis stage of the parameters both in the laboratory (nitrates, phosphates and BOD5) and in the place where the experimental units were located (pH, turbidity, total suspended solids, temperature). A final average removal of 84.14% was reported for turbidity, 94.82% for suspended solids, 35.78% for nitrates, 65.57% for phosphates and 93.99% for BOD5. With the results obtained it was demonstrated that working with an integrated system of imhoff tank and artificial wetland, they significantly removed the concentration of the evaluated parameters, since their values are within the ranges of Maximum Permissible Limits (LMP) established for the effluents of plants of treatment of domestic or municipal wastewater, also standards for environmental quality (ECA's) were taken as reference for parameters such as turbidity, nitrates and phosphates. Finally, due to the significant removal and low operation and maintenance costs, the system integrated by imhoff tank and artificial wetland could be used in rural areas that lack public sewage.
