I would get in touch with your local water authority for a quote and when someone comes out to assess it and dream up a price for connection, then you can ask him how they would go about the actual laying of the pipe.
You need to contact them anyway, as they will have to do the actual connection.
Or you could just do what a local (and very arrogant) grazier did near us. He was renting some land with no water on for his cows. So he found the nearest Yorkshire Water manhole, (about 100 meters away) connected the pipe himself and laid it in a trench he dug along the grass verge, and piped it into a trough. When YW got in touch about an unauthorised connection he gave them a load of abuse for suggesting that he should leave his cattle without water. He got away with it, they've fitted a meter, and he pays a yearly bill.
