In NSW my council, Goulburn which would be similiar around NSW requires 50,000L for a 2 -3 bedroom house. Plus 10,000L for fire fighting, something you do not have to worry about. On roof area of 240m2 these tanks would fill quicker than you think? For Melbourne this would be plenty with no worry about water consumption. My tanks size are 3.5m diameter and 3.0m high. This would be a large footprint on a suburan lot. You would probably need to build a concrete tank under the house, no great issue, seen done many times before. Look at Dincel, is a product that could be use to build the water tank. All could be plumbed into house no problems. Greywater system not sure what you plan but I think a holding tank maybe required, which adds issues. The filter I have is nothing fancy, just the very basic but I do not drink the water. http://www.waterfilterworld.com.au/single-big-blue-10-45-p-47.html?cPath=196_27 I have a fancier filter on the kitchen sink which is for drinking. I find the general filter is very good, but could have the finer filter on everything but just not required. I would be surprised if you could not plumb the whole house up, it would be very easier to have mains backup. Good Luck Pulpo Re: Tank size and filter needed for household rainwater 4Dec 10, 2010 2:55 pm Victorian Water Authorities say that you should be under 155L/head per day. We have daily showers but use half that with water efficient appliances.

Gardening, fish, showers, washing & cooking... ...also a grey water system for the fruit trees. The water tank is 8mtrs x 2.1mtrs We now have another 1, 15,000gal The filter we have is a disc one so we can wash it and reuse it. The closest one to ours is here http://www.arkal-filters.com/tech_disc.html We don't filter anymore than this type. We do filter via a couple of mesh 'traps' from the guttering. hope this helps Where you are coming from is where you are going to... Re: Tank size and filter needed for household rainwater 7Aug 12, 2011 1:38 pm A late reply to this thread. The O.P. states they are in Melbourne's South Eastern suburbs and have mains water access. As such, the O.P. is not allowed to have harvested water supply all of their household needs. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage.

Re: Tank size and filter needed for household rainwater 9Aug 26, 2011 9:33 am Redman That's actually not true. You can do it simply by not paying the bill, they cut you off and put a lock on the meter. Ouch that would be very final! We have tanks for 20000 litres - moved in a month ago and about 1/2 full. But we will still use town water. Re: Tank size and filter needed for household rainwater 10Aug 27, 2011 12:10 am My parentds are in the eastern suburbs of melbourne and they have a rainwater tank which is plumbed to their laundry etc. They have still got mains water and its not locked Re: Tank size and filter needed for household rainwater 11Aug 27, 2011 7:18 am tjilpi My parentds are in the eastern suburbs of melbourne and they have a rainwater tank which is plumbed to their laundry etc. They have still got mains water and its not locked Having a separate rainwater pumped to the laundry, and toilets, is not a total supply to all the house so it is acceptable. Water Authorities get upset when rainwater and town water can mix in interconnected pipes. This is then considered to be a 'High Risk Property'. For High Risk Properties a special backflow preventer needs to be fitted and regularly tested, too expensive for most domestic customers. The Harder You Try - the Luckier You Get !

Re: Tank size and filter needed for household rainwater 12Sep 22, 2011 12:52 am Here's and idea. We are Melb SE suburbs (easy digging) and we burried a 7000 litre concrete tank in our front yard and hence harvest all our roof runoff. I had a thread going here when we installed it a couple of years ago or check out some photos on our blog (linked below). We have 2 toilets, washing machine and garden connected and only got low when watering in 100m2 of new turf 3 times a day. Our water use is around 45 l/day/person with out trying too hard. Re: Tank size and filter needed for household rainwater 13Oct 01, 2011 11:59 am Redman That's actually not true. You can do it simply by not paying the bill, they cut you off and put a lock on the meter. The OP is in Melbourne and if you have mains water passing the property, you get billed service charges regardless of whether you use the water or not. If you don't pay the account or, for example, you breach water restrictions and a 'lock' is put on the meter, the water service provider must still deliver 3 litres per minute for health and sanitation purposes. AS/NZS 3500.1.4.2.2 states: "Only drinking water shall be supplied to plumbing fixtures or outlets for human consumption, bathing, food preparation or utensil washing." The Victorian Plumbing Industry Commission is rigid on this standard. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage. Cleaner Neater Smarter Cheaper Supa Gutter Pumper.
