Water footprint

Did you know that each of us leaves many traces on the earth during our lives, including the "Water Footprint"?

Let's understand what this important concept is all about....


The water footprint is an environmental indicator that shows how much water is used to produce the goods and services necessary for our daily lives.

It allows us to assess the impact that humans have on water resources during their activities. The water footprint can be calculated:
  • At the national level,
  • At the production level,
  • At the individual level
Of course, of these 3 options, you will be most interested in your personal water footprint, which is equal to the amount of water needed to produce the goods and services you consume.

And if you want to measure your personal water footprint, you can take 5 minutes of your time and log in to the following website: https://www.waterfootprint.org/

Make Getar Clean Again

🌀 The Getar River is an important natural water resource that plays a significant role in the ecosystem of our city. However, over the years, the river has suffered from household waste and sewage, which has led to the appearance of a musty smell that bothers us all. Instead of providing aesthetic pleasure to our citizens, the Getar River has been turned into a garbage and sewage pipeline....


ℹ️ By order of the Yerevan Municipality, the JINJ company set about solving the problem, within the framework of which it developed a project for the construction of a garbage collection station and a three-stage water basin system in the corresponding section of the Getar River.

The garbage collection station complex consists of two components:
🔹 garbage collection cages, with the help of which 90-95% of floating garbage is caught and the flow of clean water to Lake Yerevan is ensured,
🔹 a three-stage water basin system with artificial aeration, which contributes to the maximum reduction of unpleasant odors.

To the joy of all of us, the construction of the garbage collection complex is nearing completion and, let's hope, the operation of that complex will begin soon and we will have the first such system in the region.💦
