The unplanned soil sealing hinders the process of infiltration of rainwater in residential settlements, which favors the increase of the precipitation, and reduce the response time of the basin. In this context, certain flow control techniques, such as infiltration trenches are consolidated as an alternative to alleviate the difficulties related to the volume of water precipitated, especially in conditions exceeding volume. This work aims to analyze inflows of non-induced events with monitoring a trench infiltration for 5 months of continuous time in residential urban lot. The device has a capacity of up to 5.7 m3 and area of 8.8 m2 composed of geomanta, gravel, earth and vegetation in grass. The infiltration of discharges were monitored with 2 automatic linígrafos and precipitation with a weather station installed on the lot. The results infiltration estimate an average volume of 8 m3 per month for a rainfall of 220 mm. The initial abstractions of 60 mm per month, equivalent to 24% of total precipitation, evapotranspiration losses correspond to the stores and not observed. The experiment makes a significant contribution in determining volumes forecast in infiltration trencher as a compensatory meausure in urban drainage.
