You're right, water has been flowing constantly, for at least 15 years. Maybe more. If someone really billed for water, the amount would be simply huge :)
By the way, there is water with a large admixture of hydrogen sulfide, there is a smell ... Not very pleasant :))
This pipe comes from the Blue Lake, the previous post was about it. The place is quite popular with tourists, although it is located 120 kilometers from the city. And the pipe is a little away from the lake, you have to go 100 meters in total. But usually few people go to her. I found a photo, the same place at night in 2018
