ARTESIAN Wells
The first artesian wells at the source were drilled in 1932–1933. Before that, the water was drawn from an ordinary well.
In 1959, a geological expedition drilled Well No. 546 to a depth of 100.2 m. It is still in use today and supplies Lastochka water.
In 1990, a 50-meter-deep Well No. 201 was drilled on the eastern flank of the source. It supplies Lastochka 201 water.
Well No. 37 103, which supplies Acti water, is located directly on the Lastochka plant site, 2 km from the main source.
