Another one of our August jobs was installing some rainwater tanks. The task was to put something in that was better than our existing “rainwater harvesting” jug, but was cheaper than the full-on rainwater harvesting systems I’ve looked at before.

The answer was 1500-litre recycled tanks from eBay – they are used once for shipping Orange juice, then they are superfluous. We got three of them for only £80 each – great value in comparison to new tanks, and they came in an as-new condition, needing just a rinse out. We had a lot of fun getting them into position, but luckilyI had some help:

Once I’d got them in place there was the small issue of how to get the water out!

Not being a plumber I was a little nervous, but the solution is surprisingly simple. Drill the right size hole, and then a garden tap – bought from your local DIY place – will screw straight in, cutting its own thread as it goes. The only hitch? Don’t buy taps with one-way valves in – they work fine at mains pressure but the lower pressure from the water tanks was not enough to open the valves. You’ll know if you have these taps – firstly, no water will come out, and secondly they have these little white valves in the ends. Either swap them, or you can lever the little valves out!

With that little wrinkle ironed out, the tanks were all ready – here is one of them hiding behind the shed:
