Was out there last week and one of the Spanish pople living there (who I think got fed up with my filling the smalls bins in Jardin 2!) pointed out that there are some largish roll-top type bins situation on the interior road (between the Jardines and the golf course) that you can use for disposal of larger items. These seem to be split by recyclables, and people had piled some of the larger cardboard boxes to one side. I did't see them being cleared, but it must be done a daily basis - the whole site is fairly clean.
I think the skips dotted around are intended to the builders' use, but people were using them as well.
PW don't seem to give any guiance on things like this, which I think is a bit amiss. A 1 page info pack on this sort of thing would make things much easier, but there you go.
I just hope that the Spanish guy hasn't heard of fly tipping and tries to get his own back whilst I'm not there!
