Melt Tank Cleaning
Petra Looking exhausted.
With the summer building (Drewry) warm and ready for the summer it's time for our anual meltank clean.
The Meltank is a big metal cylinder 30m below the snow surface where all of our water is kept. We fill it daily with snow (which then melts- hence the name). My guesstimate is that the meltank is 2m in diameter and 3m tall (but I'm not good at guessing that sort of thing)... if it were only half full and there were some seats it would make a really good hot tub for 12 or so people.
Jamie is the plumber (who'll be leaving us shortly) and it's his job. Simon, Petra and I volunteered to help clean it... I honestly had no idea there would be so much sludge at the bottom, on the walls and in all the nooks and cranies. But I can happily say that it's much cleaner now.
Jim's been at this job for a few days now. Two days of pumping water out and transporting it to the Drewry meltank, a morning of cleaning, and then spent a long afternoon/eveing/night transporting the water from the Drewry back into our meltank. This is a job and a half, and I won't know the progress till I go to lunch.
See you can't just fill it with snow and expect it to melt (you would have thought). That would take much too long... you need to add snow to very warm water to melt it, and as you add more snow it lowers the temperature of the water, so it has to be a very slow process. The problem here is that we need the water so it can be pumped into the day tank on the main platform (it's all a big balancing act). I can't wait to have a shower again!!
