Fantastic photographs, cant wait to see the new building for real. Will do so in late September.

In the first photo could you please tell me what the orange line is coming down the slope below the summit in the foreground?

Pipes to septic tank?

I would hope that all waste is sent back down the mountain on the train!

The orange pipe took waste to the septic tank from the portacabin toilets being used by the workmen. These have now gone and the pipe will also shortly be removed.

Continuing the theme... presumably there are toilets in the new building, anyone know where their outflow goes????

The outflow from the foul system (toilets, sinks etc) will end up in the septic tank downslope from the building.

The septic tanks were used in the previous summit building, during the construction work, and now in the new building.

Having visited the summit on the gorgeous afternoon of April 19 and the first time to the summit since last years Snowdon Race i was surprised on seeing this new structure.
Looking carefully at it for nearly half an hour i was trying to figure out what needs doing to finish it of.

I was surprised really that a service train had not been provided to allow work to be carried out in this lovely weather,who knows what kind of summer we are in for, possibly the weather might be against work being carried out who knows.

Really with a project as high profile as this one work should be done when the weather will allow.
