Congratulations - good to have water - so many think they can struggle on without but it can become an annoyance.
Don't forget that at 180 metres you will almost cretainly need a powerful pump and a 3 phase 400V generator.

Take a look at http://www.pumpexpress.co.uk/ped_4sr1_desc.htm for the sort of thing you'll need.
