Dea All, we are looking at a property

No water is not good... Not too sure of cost, but hopefully someone here will give you an idea. In the meantime does the 500m or so involve going over someone else’s land?

would the water board give you a quote, including them doing everything including trenching?  At least then you'll know the worst case scenario

Our experience with ASSM (the local water supplier in Marche) is that it is their responsbility to provide water up to the meter box - which is a 1/4 mile away from our actual house, and then our responsibility from the box to the house.  Unfortunately due to the earthquake our water supply has been disrupted, so we currently have no water, and will probably have to dig a new trench and  lay a new water pipe to fix this - obviously at our cost.   And the pipe will have to run across land where we have to negotiate with three different local people.When we laid drainage channels to divert rainwater away from our house/road, we found a local man with a digger - cost about E400 per day plus materials.
