Re: Wells
An average depth deep bored well, with submersibe pump including (fixtures and fittings) and pressure vessel/controls and wiring and filtration for Iron Manganese pH etc will cost over €7,000.
The pressure vessel and filtration equipment will need to be housed so give yours self some room to allow for the equipment to be fitted and maintained.
Running costs include the cost of electricity for the pump (allow about €200 pa) and consumables (salt or chemicals) for the filtration unit. Dont forget to get your well tested annually (about €100) and get your filtration system serviced and adjusted annually.
Some pumps opertate for many years but some need to be replaced every 5-7 years. Filtration equipment typically last about the same time.
Make sure you site your well as far away as possible from your (and your neighbours') septic tanks and in a location that is protected from surface waters.
If mains or group scheme water is availiable then this is by far the better option.
