Having clean water is only part of your problems....
try getting a pump manufacturer/supplier/ installer to match the pump flow rate/pressure to match that of the house requirements. Dishwasher that requires a certain pressure and flow rate, washing machine that requires another, one shower running that doesn't have the water temp. change when a kitchen sink is used, taps that change the hot/cold flow amount and hence the water temperature as the pump comes on, pump that switches on/off because of too slow fill of cistern........and to try and do all that economically so that you get good value from the pump. It's a nightmare ,almost a job for a Civil Engineer (Water Supply). the old days of just having a siple pump are long gone, but finding someone who has the skills to do whats required is impossible. Plumbers, in general, don't know anything about pumps and new modern appliances.
