If you fit an outlet at the bottom and connect this this to a length of poly pipe, and fit this pipe to a slow dripping or trickle feed type hose, the bin will always be slowly watering the garden.
I used the black recycled car-tyre hose, but this has stopped working, perhaps from under-use. So I am off to Bunnings in the next week to buy some of the pale brown poly drip hose that looks less likely to clog. Photos when I am done.

Tip: Work out where you want the bin to sit before you do this, otherwise you could end up cutting the hole on the wrong side of the bin. I make mistakes because I think I have visualised the job correctly. In this case I made certain by taking the bin to the place where it will sit.
- Mark the place where you want to cut the hole for the outlet. Use one of the washers that came with the fittings as your template, as the inside of one will be the exact size of the hole. Any dark texta will do. Even a biro.
- Don’t make the hole too close to the bottom, as I think you want to leave room for the the inevitable muck that builds up in the bottom.
At this point you should have a clear working area around you: make sure you feel comfortable by knowing in the back of you mind that there is nothing to trip over. A clear work area makes it a big difference to your stamina, and the job is more relaxing as you are more focused on the work.

What tools did I use?
Power drill to cut the holes for the outlet in the bottom side of the wheeliebin, and for the rivet holes
Jigsaw to cut the hole in the top
Rivet gun to fasten the flywire to the lid
Round rasp to get the outlet hole size right
Tin snips or even an old pair pair of scissors can cut the metal flywire
Hacksaw to cut into the metal downpipe to fit the diverter
Multigrips to tighten the outlet fittings
Piece of wire to feed the fitting through the bin from the inside to the outside
I should have worn safety glasses, and I should have worn gloves as you will soon see.
Tip: Smart way to use scissors: hold the top edge of the scissors to the surface while cutting and cut so the bottom
blade does all the work, this makes it much easier to cut in a straight line. 🙂

- two wheelie bins. I bought these online from Wheelie Bin Sales for about $80 each and about $15 delivery (figure accurate as of today) . Very reasonable, (note: the small asterisk next to their prices means ex-GST, that is, GST is not included)
- the plastic hose connections that fit in the bottom: not sure but these were less than $10 a set
- about 600 mm X 1 metre wide quality fly-wire (that is, thick, metal and durable) about $10 or less (I used this to filter out debris as the water enters the wheeliebin
- submersible pump (I can recommend the Creative Pump people in SA and their easy to use website with excellent comparison charts for pump features. Good follow-up service too.) This small pond pump (I now realise is underpowered for the slope it has to pump up) was about $50 with $9 delivery to Melbourne
- a downpipe diverter to direct the water into the top of the wheelie bin, $30.
Tips: Before you buy, try to visualise and draw what you need. You might be able to save yourself a drive to the hardware. Like light globes, I find hose fittings confusing to buy and have returned home with the wrong ones more than once. The stores often keep the plumbing and garden fittings in separate areas. You may need to look in both.

Here’s the finished product. (Click for full-sized view.) We’ll walk through each step of the way. But before we start we need to get some preliminaries out of the way.
- Plan: how I decided to do it the way I did. You might need a plan too
- Equipment: what I had to buy, and where we bought it
- Tools : the tools I used and the ones I improvised
- Time: how long it took the first time
- Safety: where it can go wrong (and did)
I wanted to:
- collect rainwater and avoid the expense of a tank
- position the wheeliebins under two separate roofs, one for the house and one for the shed
- buy something I might be able to move if I had to, or use for another purpose
- reduce the risks of mistakes as I am new to the water collecting game (even my forefathers, the German farmers on the peat marshes North Sea probably did not have to think a lot about droughts etc, but that’s another story)
- avoid the expense of waving the householder’s magic wand at a plumber: its often more fun and satisfying anyhow to do it yourself
- work out some way to get water uphill — we live on a steep slope
Looking back, I believe the plan was mostly good, and time well spent. I now have two of these 240L collectors set up. One with a submersible pump. But, I have to confess something here and now. Yesterday I fitted the tap to a new 1700 litre tank. That tells you that a wheelie bin is limited in one important way: what it can hold (mine are 240L). I’ll be honest, the planning phase was hampered by a lack of financial willpower, and a feeling I could do it on the cheap. Some just call it being tight. I prefer to call it thrifty, thank you! I guess I was also over-optimistic: I did not realise that 240L is not a lot of water.
