Water, water everywhere and not a drop to drink July 30, 2006
Tim’s post about the water referendum in Toowoomba has started me thinking. While I’m a little disappointed that it failed, I really can’t blame them. I don’t think I could in all good conscience vote to add water recycled from sewerage to our drinking supply. I just couldn’t trust its quality enough.
I do think, though, that we need to be using as little fresh water as possible and reusing/recycling water where we can. It’s not always easy to do, though. It’s not possible to recycle the grey water in our house. All the pipes go straight down through the slab and there’s nowhere we can intercept the water without major excavation, etc. One summer we did redirect washing machine water onto the garden, but it’s not particularly healthy for the washing machine. It puts too much strain on the pump motor, so I don’t really want to try that again as I’d rather not have to replace the machine any time soon. Bailing bathwater out in buckets is something else we’ve done and may do again this summer. It’s hard-ish work for what feels like little gain, but if water restrictions are tough and it will help keep the garden alive, then I’ll do it.
The front garden won’t need much water this year. All the plants out there are natives or succulents and they’ve all been there for over 12 months, so they’re well settled in and hardened. In the back yard I have grand plans to move plants and plant out pots, as well as growing some vegies, so there’ll bit more water use there. I’ll do the watering either by water weeping house under the mulch or by hand, so (fingers crossed) none of it should be wasted.
The garden is one place I’d be happy to use recycled sewer water. It would be a major engineering work, but I’d love to see recycled water plumbed to all garden taps. I think the stats are that about one third of all water usage is on the garden, so it would make a substantial difference. It definitely needs to be a feature of future housing developments, particularly in areas like ours. Werribee is in a rain shadow so we get less rain than other areas. It all falls on the YouYangs. We get about half as much rainfall as Tim’s side of town. The Werribee area is also where most (?) of Melbourne’s vegie growers are located. And, serendipitously, it’s where the supply of recycled water is situated. It seems logical doesn’t it? Yet, apart from some vegie growers trialling recycled water a couple of years ago, we’ve heard little or nothing from the various tiers of government about plumbing it to existing homes or putting it in new estates.
