The Heyga Plant

The Heyga plant is situated on Válinum, next to where the river Breiðá meets the sea.
 
A pipeline runs 305 meters up the mountainside and into the mountain where it connects to a 1000 meters long tunnel. The tunnel runs to Heygadal valley where there is a well holding some 2,100,000 m³ of water.
 
The well, called Heljareyga, is surrounded by a 23 meters tall concrete panel.
 
Tunnels and channels have been constructed south to Gassadals in order to increase the flow of water to the Heljareyga-storage.
 
The Heljareyga waste area is 19.1 km².
