Thread: Water Tank - should I bother, with Desalination coming?

From a sustainability point of view, it is always better to avoid a problem than trying to fix it afterwards, so fitting a tank is a better solution than relying on a technological fix later. If it cuts down on your water use, then you will need to use less water cleaned and transported by someone else.

Of course whether you think its worth the effort and cash is a different argument!

If you think that the government is going to spend all that money on the plant and leave the water rates low, you might be in for a surprise.

I'd put the tank in.

Paul, we have a galv-iron 9000 litre tank, and put it in new just over thirty years ago. We use it for drinking, and have one of those plastic filters that sit on the benchtop which we top up through the course of the day. I note that two of us with a couple of "drop-ins" manage to drink upwards of nine litres a day in coffee and tea as well as glasses of water. The filter does not kill bacteria but is supposed to take out heavy metals to a degree, as well as solids. We have never had a "Belly Bug" from the water, but each roof differs, with cats or possums as well as too many pigeons or doves dropping the business up there. Dead vegeatation causes sludge and slime as well.

A tank that big will not supply your toilet and through a long drought, let alone your washing machine. My 9000L tank has left room for only pedestrian traffic either side of it in a driveway. This is much bigger than a lot of household tanks, and so it's up to you, but you will need to have a proper pump rigged up to it, on a real good pump stand. This should be thought about carefully, as the good ones are self-priming. The toilet can feed from gravity, but the washing machine needs to be working hard on wash day, and SWMBO will become annoyed at having to wait. Not even sure if gravity will work on Auto washers . . they may rely on pressure to switch their taps on and off.

Twin tub washers are another story, and the "Laundry Person" will have to stand and watch the tub fill, in order to manually turn off the tap.

All said and done, you can save paying for one helluva lot of water over the course of a year. Make sure every drop off of your roof is fed into the tank, with overflow piped out into the street.

... with overflow piped onto your garden....

Get the tank. Think about more tanks.

1: You can bet on the Govt. (or whoever they sell the Water Board off to) will increase the price of drinking water dramatically. The 'desalination' plant will probably be powered with diesel pumps - fuel will go up & up & up. Any assurances about prices are just hot air.

2: If you have your own tank/s, you won't have to worry about broken water mains & such. In the event of a bushfire threatening your property, the firies can use your water tank to try to save your property - mains water often fails in bushfires due to high demand.

3: It will all cost more tomorrow.

Thank you all for your replies, we're now definitely sold on the water tank idea. We were 95% sure. I plan to install it all correctly, later, after its filled up enough to be of any use. If I could fit a bigger tank down the 2.3m wide driveway I'd do it, as I have plenty of space out the back. I could hire a crane. We are thinking about about trying to future proof ourselves, this should help.

cheers

A. (Get a water tank) + B. (Claim the rebate.) = C. (Council raises rates for water storage.)

A. (Get a water tank) - B. (don't claim the rebate.) <> C. (Council does not raises rates for water storage, unless they find out.)

Groggy, What the?

A lot of BIG tanks are less than 2.3 meters high so get a biggie and roll it into your backyard

We looked at plumbing a 2500lt tank to toilet and laundry but in the end the expense wasn't worth it. We still got the tank but will use on vegie garden, kiddies pool, washing paint brushes etc. We are water wise with a front loading washing machine and water wise toilets and we don't flush all the time. We all bath together 3 times a week so for a house with two adults and two toddlers we use around 300lt per day of water, but that usually includes some water for the vegie garden in dry times.
It's a pity that we continue to be the one's who keep trying to improve our use, yet I have seen families on that Carbon Cops TV show with 2 adults, 3 teenagers in a house using 1,700lt of water per day!!!!!
We felt for the cost of the pump (using power!) and connection and our already little use of water that it was best not to connect. Use the money on mulch, compost bins etc.

I can see where Groggy is coming from - will the council/water authority decide, at some future date, to institute a levy on water tanks in order to pay for their overpriced & under utilised de-sal. plants?

I remember that some Electricity suppliers were charging a levy on solar hot water systems installed on rural properties a few years ago, and again, in rural areas farmers have been hit with 'levies' on their dam capacity - after being encouraged to increase on-farm capacity. I wonder if those same farmers have launched an action for damages against the water authorities for failure to deliver sufficient water to their farms?

If you claim the rebate for the water tanks your rates go up - so I am told (by a number of people from separate areas). Caution, possible urban legend.

Urban myth indeed.

My rates haven't gone up.

Anna Bligh specifically said she would not allow local councils to charge water storage rates on water tanks.

Good on her! Since you're closer, would you mind telling her to get off her bum and come down to Victoria and stop it then?
