Great idea, Andy. Good on you for sharing.

Points to consider:

- Definitely use primer before glue on PVC pipe to ensure a decent bond. The primer cleans and softens the surface to allow the chemical reaction caused by the glue to take place. No need to wait for the primer to dry (it is a solvent so it dries very fast anyway).

- Push the glued fitting on the glued pipe promptly. Hold for about 30 seconds, longer at lower temperatures. Good handling strength is achieved in 15 minutes.

- If making multiple units, keeping it simple (and as light and cheap as possible) is a good principle. Glued end caps, if done well, are the best option. Easily removable ties such as old bits of rope, string, twine, bungee cord (Ocky strap) can be used. Learn to tie an easy to undo knot if you don't know already. Blue plastic packaging strap and those white plastic buckles are another option. These are available at Bunnings (big chain of hardware stores in Australia) along with the PVC pipe, fittings solvent and glue. Most hardware stores carry these items.

- Each unit will hold just under 10 litres of water. If you are carrying water into a series of units, consider how much you can carry at one time and determine the number of units on each run accordingly.

- If there are unburnt pockets of bush, locate your units in the vicinity. Surviving animals will congregate in these areas.

- When establishing a run of stations, try to keep them on roughly the same level (as in height above sea level) so you are not walking up and down the slope too much.

- You could tie something with high visibility at eye level at each station to help you find each one until you get familiar with the terrain.

- If the water is not being consumed, try another spot. You will need to monitor the stations fairly regularly at first to get an idea of how often you need to refill each unit.

- Be prepared to keep at it for a while. Drought breaking rain is not expected for most of Australia this year.

I know a lot of this might be obvious to many of you but judging by the questions I see in the comments on a lot of Instructables, people generally appreciate an easy to understand explanation of something that might be totally new to them.
