What size is your water tank...??
There is a water supply firm in Tortosa and he will deliver to "most places" but it is in loads of 13000 litres.If you have a small 1000 litre cube there is a font at the back of Bitem on the road leading up past the cugat building near the cemetery.You would obviously need a strong trailer (the tank will weigh 1000kgs when full) and maybe 2 of the tanks plus a small water pump to transfer water.
