For 15 years in Tyumen they have been doing targeted storm drains according to the city authorities, since 2011, the road department has been systematically introducing new closed and open drainage systems. For this purpose, planning documentation that passed a state examination was used, taking into account the intensity of the "small and medium" rains in our city. In the case of "torrential" rains, the capacity of the storm sewer collector is not sufficient to carry and flow water immediately further along the collector. This, in turn, leads to the dispersion of rainwater along the territory (all storm sewers are filled, and flooding of areas occurs in the lowest places), explained the mayor's office. Here we are always in touch.
