Water collection options for the garden?

[Ystranc]

Someone on a camper forum who said he worked for hoze lock said there is no legal requirements controlling what hosepipe is made from.
This mentions legionella may be a risk too.
I have a hoze lock pipe with a timer on it feeding my polytunnel drip system every morning, plus another connecting two waterbutts, but I'm looking to change to mains water blue 25mm or food grade hose pipe soon. I have no idea if plastic from the hose can end up in my tomatoes?
Are water butts food grade anyway? These might be an alternative?

You shouldn’t use the mdpe blue pipe above ground if you can help it because it isn’t UV stable. Instead you should use the black HDPE pipe and compression fittings.

Are you familiar with the costs of installing a Borehole?

No, but I know 2 people that drilled their own in their back garden - one in ascot and another one in Northampton. We hand drilled one nearly 7m deep at the bushcraft club which produces water.
I guess cost depends how deep you need to go?

SI demon strikes again.

I am collecting water from about 50 m² roof area to 1000l cube that did cost me about eur100. It has been there for about 20 years and I think it has run dry once.

Doh!

 

[MrEd]

Do you need to be over an aquifer(?) though?

Don’t think so, I think k you have to just get to the water table - I have zero knowledge though, I just know a couple of people with boreholes the dug on their property that work well

For anyone wanting a food grade water storage system I would recommend using a palletised IBC cube but try to buy one that has been used to ship syrup for a drinks company. If you’re planning on using it outdoors then you may want to consider using one of the black IBC cubes and insulating the pipework.

That is a good video, thank you
Does one of the IBCs have an overflow? How do you connect that, would it be down pipe sized I spose?
One of my hoses is the same type of red food grade hose used in campers from when we had one, but when it's even a bit chilly out it gets super stiff to unwind.

Ours doesn't because we aren't on mains drainage here in the Fens. If I was, I would connect the first IBC using a water butt connector. That forms an automatic overflow back into the drainpipe when the water reaches a set height
