Since the club is completely underground, it's not surprising that a sewage lift pump is required. However, these pumps are prone to clogging, which can be a real pain.

But, of course, it can't work miracles: we kindly ask that you do not throw anything in the toilet other than paper, and make sure to flush with plenty of water.
