The present work aims to evaluate the effect of small flow dampening reservoirs installed in the front of the lots in subdivision, regarding the reduction of the discharge peak and eventual decrease of the diameters of the drainage galleries, in relation to a conventional drainage system. After a review of the literature on the subject, the calculation of the drainage network of a certain street is carried out in the conventional way, with the presentation of the respective dimensioning worksheet. In sequence, the Routing Simulator Application is used in order to verify the reductions in the flows caused by the damping devices, with the presentation of the new dimensioning worksheet with damping. Finally, the flow values for gallery sections and diameters are compared, considering both scenarios. Lot reservoirs were responsible for a reduction rate of 21% to 35% in flow rates, with a decrease in diameter in 50% of the evaluated galleries. |
