Abstract
Runoff drags pollutant from different urban surfaces causing diffuse pollution in natural or artificial
water bodies. To solve this problem, several solutions have been developed to purify the run-off water before
the final spill, but still it is necessary to improve the applicability and efficiency of these systems. The project
that is presented in this paper is focused on developing a System for Catchment, Pre-treatment and Treatment
(SCPT) of contaminated runoff coming from impervious surfaces. The concept of SCPT is an on-line, up-flow
filtration system, with the main elements of pervious pavements, which are being geotextiles and open grade
gravel. The objectives of this research are to determine the influence of the main factors that affect SCPT
efficiency and to evaluate the effects of SCPT long term use in its operational behavior
