    The present experimental work, determines the hydraulic efficiency in the collection of water in drains implanted in urban roads, also compares different configurations of sinks in terms of their hydraulic efficiency based on previous research, and validates the present work by inserting new geometric parameters of the configuration of sinks suggested by current regulations. In order to comply with the proposed objectives, a software with application of computational fluid mechanics was used, where three-dimensional simulations are carried out and is a tool that allows the resolution of problems related to fluid movement. The test platform was modeled on a real scale, with a transverse slope of 2 and 4% and a longitudinal slope of 0.5 and 4%, the flow rates on the road vary from 16.91 l/s to 111.65 l / s. Two models were considered for the analysis of hydraulic efficiency, model S1: a sump located on the track, model S2: two sinks placed in series on the track. After this, the simulation of each scenario is performed, the flow values captured by the sump are taken at 25 seconds because the flow stabilizes from 20 seconds. The hydraulic efficiency for the modified type T45 sump with circular bars is calculated using the flow rate values. The results indicate that the modified T45 model with circular bars, has greater hydraulic efficiency than the normal T45, therefore, it is possible to implement these on the roads for better rainwater collection efficiency, in addition to the hydraulic efficiency of the model S2 is larger than the S1 model, so if you have the appropriate geometric conditions on the track, you can use the S2 model, if you want a larger hydraulic feedback.
