The region of Banská Štiavnica lacks significant sources of flowing surface water. That is why tajchy were designed to store water derived from precipitation. Channels with the overall length of 72 km diverted water from the rain and melting snow to sixty reservoirs.
Banská Štiavnica's limited access to flowing surface water prompted the creation of tajchy to harvest and store rainwater and snowmelt. A 72-kilometer-long channel system funneled this water into sixty reservoirs.
