I've started the first phase ... I've been driving a 6 tonne 360-degree digger for a week - and have reduced the size of the pond to something manageable, piped 25% of the roof downpipes into it, and started widening the drive a bit to make it more usable for parking for parties etc.
Anyways, enough wibble ...
I'm just about to start connecting the downpipes from 50% of the roof, and 100% of the utility/garage, and I need a tank to harvest this water (and a pump to get it to the Veg Patch)
I would appreciate advice on rainwater storage tanks that I could consider to hold this water.
Plan is to pump it to garden for irrigation. I suppose some filtering (e.g. WISP) would be beneficial. I have laid 100M x 25mm MDPE to the "garden". I also need to lay some ducting for electricity to the tank.
Rather than having a "big enough" tank for the longest possible drought
I think a tank suitable for a big-ish downpour, and then pump to IBC's will do for me.
So my questions are:
Any advice on makes/brands of tank (inc. WISP filters etc. if required)
How high do I need to mount the IBC's to get enough water pressure to drive an irrigation system for the plants? (Or do I need to pump it anyway?)
Roof Collection Area for the new tank is about 270 M^2 (plan area, excluding "pitch" etc.). Annual rainfall (East Anglia) is about 575mm
Thanks,
Kristen
