On chatting to the Thai team I feel
The same to is that if we get an outside contractor to
do the water tanks and pumping system it may cause problems with
Pornpol and they would be upset with a loss of face and make it very difficult for an out side contractor to do and if any thing goes wrong which was Pp fault they would just blame the other contractors work
By all means if you want to use some one else we can but thought be good to let you know the implications of using some one else
