Dump your grey water and chemical toilet to the big hatch on the ground. Disgusting, be careful of the floating lumps. No working fresh water tap. Personnel very uncaring. 5€ for all this.

They charged us 5 euros just to drain black and gray water and advised us not to load water because it is not drinkable. Fools us to go ask, we could just download!

Chemical toilet can also be emptied in the gray water - the system has been changed, you no longer need a key - fresh water hose is on the left of the house - we connected our own hose by loosening the clamps and then screwing it back on again, it worked without any problems
