This year’s drought in the Czech Republic is likely to lead to increased drinking water prices for consumers. High temperatures and record-low river flows this summer caused a concentration of harmful substances, raising water treatment costs by as much as 20 percent. Additionally, a growing number of municipalities are being forced to invest in new reservoirs and connections to distant water supply networks due to water scarcity. These infrastructure investments are expected to further contribute to higher water and sewage rates. The specific locations and the exact amount of the price increases will become clear no later than December. Consumers across the Czech Republic should prepare for potential increases in their water bills. The situation highlights the vulnerability of water resources in the face of climate change.
