small engineering type problem.
Discussion
Pub acquaintance ( so not a friend as such) of mine has a well in his garden (5.5m deep)...he is also on a water meter as he bought the property a few years ago. He wants to use the water from the well to water his garden plants/lawn and would like an electric pump to get the water from the well, along a pipe and out through a tap/ hosepipe system without it affecting his metered water system.
I already suggested manual pump to get the water up from the well ( eg...like they do in Africa) and then possible means to automate this function. Butterfly valve and/or gate valve type mechanism to hold the water at the'tap' end.
BUT he said he'd searched for such a system on internet ...and there wasn't anything currently available.....anyone know anything different that can fix his problem?

The issue is the 5.5m lift. But there must be an electric pump that can deal with it.
Yes that is the issue, but it also needs to be able to do more than that....no he can't find a pump that can deal with it.It also needs to be able to push the water along the ( needs to be made) pipe work and afix to a tap type mechanism...to be turned on at will. To ignore the everyday mains pipes as they are fitted to a water meter.

But then you have to coordinate switching on the pump with opening the tap, because a pump has to pump somewhere.The pump acts as the tap. Switch it on = water comes out. Switch it off = water stops. Just like a pond fountain but with a hose attached instead of a fountain.
All you need is an appropriate pump, a footvalve (stops pump unpriming itself)(or a submersible pump as suggested) and a length of hose to wherever you want it.
Well that's my best shot anyway!

I suggest he uses a pump to fill an elevated water butt from the well and then use that with standard hosepipes to do the watering.
Unless the butt was quite high up I doubt it would provide enough pressure to use a hose effectively.Pigeon said:

Exactly what I was going to suggest.Simpo Two said:

Quite...I also see problems there with a lack of head.
That's the one. So rather than pump the water up really high so it can run down again under gravity, you remove the butt and the height from the equation and end up with just the pump and the hose

This pump is advertised as 1.1bar, the 5.5m well requires just over 1/2bar to lift the water, so use the pump to lift the water into a water butt, then the same pump to pump from the butt to the garden, one pump and one butt required.
Or am I missing something ?

Have a look here, not necessarily the cheapest but will give you an idea

You need to look for an appropriate head height (depth of pump from service and add a bit, I would suggest that perhaps 8m would be right for a 5.5m well. (remember any hose pipe will be held approx 1m above ground by the operator.

I installed one of these http://www.gardena.com/opencms/opencms/AU/en/produ... last year, draws water up about 3-4 metres from a large submerged storage vessel, but can cope with upto 9m. Will then pump up a further 44m. The nice thing with this one is that it contains a pressure switch. So turn the tap on and the pump starts, turn the tap off and the pump stops. Seems to do everything you need unless I'm missing something.

So your solution would involve further electronics ( not that that's a bad thing...if they work )
It's only an on/off switch for the pump - which you need anyway:www.machinemart.co.uk/shop/product/details/double-...
I think the 'problem' is easier than you think

You'll need 5.5 bar of minimum pump pressure to raise the water 5.5m 
and some additional flow/pressure above that to get any quantity from it.
