Not convinced that tunnel has to be linked in the lead, as it's a common term
I wouldn't link this in regular prose, but I feel that as this is an article about a tunnel, there is a significantly above-average chance that a reader might want go to the tunnel article. Arsenikk(talk) 11:51, 4 June 2012 (UTC)[reply]
The tunnel runs mostly through Cambrian-Silurian sedimentary slate no need to link sedimentary
Thanks for pointing out the correct term. Arsenikk(talk) 11:51, 4 June 2012 (UTC)[reply]
Therefore, one of the main focuses in the Skaugum Tunnel project was to avoid similar leaks, and the criteria were set to 4 liters (0.88 imp gal; 1.1 US gal) per minute per 100 meters (330 ft). This was achieved by using sufficient time for the pre-injection. Don't understand what is meant by "the criteria were set to 4 liters (0.88 imp gal; 1.1 US gal) per minute per 100 meters (330 ft)", and I don't understand the second sentence.
