The price of water - what is our drinking water worth?

Water is relatively inexpensive enough so that for many, it does not really register in our wallets. But how is the price of water calculated in the first place? What does a cubic meter of tap water cost across Europe? And, above all: What can we expect in the future? Here are some answers to these questions.

How can you reduce non-revenue water levels?

With the climate change and dramatic temperature increase over past years, our water consumption will rise too. We will need much more water for agricultural purposes and for everyday life. Water will undoubtedly be a valuable resource in the future that should not be wasted. Yet our water saving capabilities are far from appropriate numbers.

Check valves are vital fluid control components in piping systems that serve various critical applications. These devices prevent backflow and the numerous problems associated with it. In certain applications, they are also used as vacuum breakers. Check valves can be found in water, sewage, gas, chemicals, and other piping systems.
