Talk about third world countries!
They never even found the problem!
Apparently they could tell the water was contaminated with "bugs" at the point where it entered the pipes that went to houses - but never found where the problems came from
The "bugs" apparently often come from sheep poo on the hills
I amazed a lot of people to find that the hills of North Wales actually have sheep on them and it rains!!
it was all rather weird when you read the details
anyway - eventually they installed a UV thingy to kill all the bugs and it was OK after that
The electric was also dodgy for a lot of the time I lived there - it cut off quite often for hours at a time
It is interesting to note that this was all in the only City in North Wales at the time - not some remote village in the middle of nowhere!!
