Complications of conventional rainwater drainage


In recent decades, it became clear that the massive expansion of the rainwater drainage also brings serious problems. Firstly, stormwater discharges, and particularly in combined systems, produce a significant contaminant load. Add to that, the increasing hydraulic load, in terms of the hydraulic stress. Secondly, traditional drainage disturbs the water balance, where groundwater recharge and its role in supply of potable water in dry periods, is restricted.  In addition to this, evaporation is reduced, compared to the natural water balance cycle where evaporative cooling potential is minimized.
