IM not so sure about this, as we have nearly emptied a 46000 litre pool (during the course of summer) onto our recently estab landscaping! I was shocked at how quickly it went down and how much water you actually use.numbercruncher said:20 to 25k Litres is alot of water especially if its only going to service your garden, and especially considering the good rain fall you normally get of the fraser coast, rather than 4 tanks you would probably be better getting one large one (per litre storage cost would be alot less), savings both ways as the installation of one large tank vrs 4 smaller would also be less.
Re the "good rainfall you normally get on the Fraser Coast", over the last couple of years we have commonly gone more than two months without a drop of rain. The rainfall is nothing like it was ten years ago.numbercruncher said:20 to 25k Litres is alot of water especially if its only going to service your garden, and especially considering the good rain fall you normally get of the fraser coast, rather than 4 tanks you would probably be better getting one large one (per litre storage cost would be alot less), savings both ways as the installation of one large tank vrs 4 smaller would also be less.
Thanks a lot for those suggestions, Rafa. The "first rain water diverter" sounds essential but no plumber quoting so far has even mentioned it.Rafa said:I haven't got one in yet, but have been heavily researching this.
It all depends on the room you have Julia, But i have seen polycarb big round circular tanks, 10000L ones for only 1600 bucks (from Statco i think)
If you can do that, thats the best value for money, the modular ones could cost you a lot more.
All in all, depending on what you want to use the water for, its highly advisable to have a 'first rain water diverter'. Essentially, its a small tank that collects the first lot of water from the roof (with all the contaminants). This could be 200l say, and only when this is full, will your core tank start filling up. This small tank has a slow drain which discharges into the storm water over a period of a many hours.
I would recommend this especially if you are going to use the water for the pool.
Then some other options are submersible pumps to get some good pressure for your sprinklers (or if you do eventually have to pipe it in your home).
Some other things to think about are roof catchment, guttering network, etc...
Exactly right, constable.constable said:IM not so sure about this, as we have nearly emptied a 46000 litre pool (during the course of summer) onto our recently estab landscaping! I was shocked at how quickly it went down and how much water you actually use.
Still havent gotten around too hooking up the storm water to it so it can refill this winter ...fingers crossed.
Pump. If you want to run sprinklers then you'll need a pump unless you've got a really steep block and the house right at the top. In practice, you'll need a pump for sprinklers.Julia said:Smurf, I have one area in drip system but need sprinklers for the main part of the garden, so assume I'd need a pump.
In a time of zero rainfall, I'd use considerably more than 500 litres per week for the garden, probably more like 1500 per week when the weather is in the 30's and windy. And then about 1000 litres every three weeks to top up the pool, depending on humidity levels.
Good heavens! But you are in Tasmania, aren't you Smurf, with plenty of rain?
The water diverters are commonly sold (at least in Tas) by tank suppliers. It should certainly improve the quality of the water in the tank by keeping much of the pollution out of it.Julia said:Thanks a lot for those suggestions, Rafa.

Can you tell me where I can get more info on the submersible pumps? The sprinkler system has to cover a large area, so good pressure is essential.
With a large enough pump you could do away with the tank completely and just pump directly into the sprinkler system. You really only need storage if the supply is intermittent (rain) or doesn't come fast enough when you want to use it. If the bore pump is sufficiently large then that won't be an issue.insider said:Have you considered a BORE water pump (water from deep under ground)? with one of these you'd just need a small tank because the pump would keep it full all the time...
Julia said:Thanks to everyone for your really helpful input. Much appreciated.
I thought spear pump was another name for a bore but it sounds as though I was wrong here?
Can someone tell me the difference?
I did investigate getting a bore but was told it wasn't possible in my area.

A bore is a cased hole which you insert a suction line inside to get to water. A spear is usually used in sand and is a pipe with a perforated spear head which can be driven into sand to the water table and doubles as a suction line. Because it relies on suction from the surface it is limited in depth to a little over 20ft. It is common in coastal areas and dry river beds. A bore can be much deeper.insider said:Not sure... I know that the industry has several trady names so it may be called that in Queensland... If it gets water from underground then I guess it's the same...
