Gruba Kaśka, Water well on Vistula River, Warsaw, Poland
The cylindrical water intake structure collects water through eleven drainpipes located between 4 to 8 meters beneath the Vistula riverbed.
The facility began operations on September 22, 1964, introducing an innovative water collection method that replaced previous land-based filtration systems.
The name Gruba Kaśka, meaning Fat Kate in Polish, reflects the local tendency to give infrastructure facilities familiar, personified names.
The facility pumps between 90,000 and 120,000 cubic meters of water daily through a natural filtration process using the river's sandy bottom.
Two maintenance vessels, Chudy Wojtek II and III, regularly clear pollutants from the riverbed to maintain the water intake system's effectiveness.
