  • Heavy rainfall caused temporary street flooding in Koprivnica, Croatia, prompting questions about the drainage system's performance.
  • The director of KC Voda stated the system largely functioned as expected, with new retention basins successfully managing excess water.
  • Blocked storm drains, due to debris from the storm, were identified as the primary cause of localized flooding, while separate pump issues affect underpasses.

Following heavy rainfall that temporarily submerged parts of Koprivnica, Croatia, on Sunday, questions arose regarding the effectiveness of the city's drainage system post-agglomeration project. Zdravko Petras, director of the municipal company KC Voda, assessed that the system generally performed as anticipated.

Petras explained to Hina that the main issue causing temporary street flooding was blocked storm drains, clogged by branches and leaves carried by the storm from roadside trees. While the drainage system was heavily loaded during the initial 30 to 40 minutes of the downpour, most streets cleared quickly once the water receded through the collector network.

The retention basins filled up, and the water was then pumped through sewage collectors toward the suburban settlement of Hereลกin. All overflow systems were functional, and the Koprivnica stream was not even half full.

He emphasized that the five new retention basins, built as part of the agglomeration project, played a crucial role. These basins successfully absorbed the excess water, which was then pumped via sewage collectors toward the suburb of Hereลกin. "The retention basins filled up, and the water was then pumped through sewage collectors toward the suburban settlement of Hereลกin. All overflow systems were functional, and the Koprivnica stream was not even half full," Petras reported.

Petras clarified that the frequent flooding of the underpasses near Podravka is unrelated to rainwater drainage but stems from faulty pumps responsible for draining those specific areas. He also noted that maintaining storm drains and rainwater drainage is not KC Voda's responsibility but falls under the purview of road infrastructure maintenance services. Despite the temporary blockages, Petras asserted that the agglomeration project significantly enhanced the system's resilience to heavy rainfall, adding 13,000 cubic meters of retention capacity that previously did not exist.
