Our borehole has the stainless steel pump unit submerged down the hole (approx 65m deep). This is controlled from an electronic panel mounted in our garage. The electric feed goes from the panel, down to the pump. The water feed comes up from the pump to a pressure vessel, also mounted in the garage. The pump pressurises the vessel up to about 3 bar, and then the controller shuts it off. As usage drops the pressure to a set point, the controller causes the pump to kick in again (for about 20seconds).
The borehole is sleeved for the first 20 metres, then just through rock. We have a sediment filter in our feed pipe, but only because the "builder" made the mistake of cutting off the plastic sleeve flush with the ground, allowing surface water to leak into the borehole.
Hope this helps.
