A: Categorically 100% YES.  While there is a little more to the process of preparing a tank for drinking water, it is the most natural, chemical-free and purest source of water available. All raw POLY POWDER – RESIN materials are compliant to minimum Australian Standards 4020.

If you are planning to or hope to use your DELUGE Poly Rain Water Tank to harvest FREE rainwater water for the use in toilets throughout the house or use the collected rainwater in the laundry & washing machine or garden use for lawns and shrubbery, the captured – harvested water should require no filtration or UV treatment at all and is ideal for such uses.

Please be careful when drinking from your Tank that no vermin, bat droppings, dead birds – possums or silt sitting in gutters, toxic fallout form localised industrial plants, smelters, coal plants etc

A: We get asked this a lot of times. Sadly this is like asking how long is a piece of string ? All Rainwater Harvesting is totally geared to & very much dependent on the size of your tank and the volume of rainfall in your local area. Obviously rain water falls vary tremendously You can work out your potential capture ability by determining the roof surface area – simply multiply the length of your roof by its width, then multiply this number by the average rainfall of your location. (Check out Weatherzone for details). Approximately 1mm of rain falling on 1m² of your roof provides 1 litre of water straight in your tank, so as an example, it would take approximately 20mm of rain over a surface area of 150m² (a typical 2-3 bedroom home) to fill a 3000L tank.

A: Hey, what they don’t know won’t hurt them – However, you might like to check with your local council on their requirements. The rule of thumb that if you live on a suburban average block of land then any Tank up to at least a 10,000 Litre is fine – and any pad taking up 10 sq./meters is fine. That said – the most common elements to satisfy “most” the council include:

• For the average DOMESTIC – SUBURBAN House Block – a Submission of a Development Application (DA) for tanks with a capacity greater than 10,000L
• Some Councils ask for signage on the tank (e.g. ‘Rainwater in use’)
• ‘Just be careful using pumps only within allowed periods to comply with noise pollution laws – the rule of thumb is treat your neighbour as you wish to be treated and DON’T water your Lawn using a pump etc at 2am in the morning ! Allow common-sense and decency to prevail.
• Generally, the process is very simple and we find the majority of local councils often encourage the local residents to adopt a water tank and rainwater harvesting solution for their home or business.

A: It’s a fallacy and in NO WAY at all can you “taste “the plastic. This is a nasty “myth “ that the Corrugated Metal Tank manufacturers and the likes of BHP seeded to scare folks from purchasing a Poly Tank- don’t be fooled please folks. ALL tanks we proudly offer are made with the highest quality UV-stabilized polyethylene. It is virgin food grade, ( NOT RECYCLED RE-GRIND ) with absolutely no effect on the water in terms of taste or smell. Consider the Tank to be an Australian Standard complied large Plastic Cup. TOTALLY harmless and we urge you NOT to be fooled by Metal Tanks which also have a plastic liner or fused plastic film as does BHP’s AQUAPLATE®.

Australia is certainly one of – if not the driest inhabited continents in the world, therefore water conservation is, and will continue to be a major concern right across the country. Harvesting and storing rain water in your DELUGE POLY TANK is a very efficient and cost effective way to re-use water around your home, for commercial use in factories and Farms right across the land.

Should you reside in a region that is not feed mains water and find yourself “off the grid “you are not then harvesting your very own rainwater is the best way to capture, hold and deliver fresh & clean water to the inside & around your home. If you are connected to a municipal mains water reticulation service, having a tank gives you the freedom during a drought or water restriction period to use your water when and how you choose.

Regarding your Homes aesthetics and a Tank looking like a monolithic mess we proudly off all sorts of shapes and sizes to suit any application and need. With over 22 Colorbond® Colours on offer we have all needs well covered to assist your proposed Tank to blend rather than stand out like an ugly sore thumb !

Might you be worried that a water tank will affect the look of your home, commercial building or farm you should not worry. Here at DELUGE POLY RAINWATER TANKS proudly offer an extensive range of shapes and colours to blend into your surrounds. While we offer many options of Tanks to blend with any application the real upside is you will begin immediately to reduce your water bills as well as offer added value to the residence that will show when it comes to the time to seel up and move. Having Tanks already set up is a distinct advantage and property value enhancer. You will NOT lose money or value by installing a Rainwater Tank – EVER.

Some states offer incentives & or rebates for installing a rainwater tank. Check if you are eligible here.

This will depend on a few different factors including your budget, usage of harvested water, area to fit the tank be it back yard or just down the side of your Home or Garage walls, if you have a pool which will consume a lot of water during summer due to evaporation etc. Really as a guide the average home with 3-4 people should never think below 300-5000 Litres.

The GOLDEN RULE is – that you can NEVER Harvest too much FREE rainwater –it’s that simple.

This will vary significantly from customer to customer. Household customers may intend to use the rain water to fill their pools and water their gardens while agricultural customers may use the tanks to store large amounts of stock water for the farm – resulting in very different tank solutions.

Once you know the square meter measurement of your roof/hard surface and the approx. level of rainfall annually (see rainfall charts), you can calculate & determine the amount of rainwater your roof can collect and therefore what tank size would best suit your needs. All this said- YOU can NEVER harvest enough water to use around your property. As above, we would suggest at least 3,000 Litres Tank to 5,000 Litre MINIMUM and up to 10,000 Litres for an average house block if you have the room

For safety – it is always best to have at least ONE other on site to assist the driver who will be on his own.

The requirements to assist will grow depending on how large a Tank is being delivered.

PLEASE NOTE : The driver is NOT the Tank installer and will always help within reason and reasonable time frame to assist the Tank as close to the pad as possible and if easy & straight forward access it will be straight onto the prepared pad.

We DO NOT DUMP and RUN – BUT we are NOT the / your Tank installers either with due respect please. The driver will decide at his health & safety discretion as to how best he can and will help you. It all comes down to care and respect. Naturally the Driver won’t be lifting Tanks up over fences, across pools, over garden sheds etc. Again, discretion, reality and the decency & fairness tests will all be applied – yet rest assured we are here to serve you. Dump and run is NOT our modus-operandi !

We have put together a step by step guide to installing your Tank. There are two types of delivery; on-site delivery and a roll-off delivery. On site is where you have followed the guidelines and the site is prepared for a safe drop off by the drivers who will get the Tank as close he can to the prepared base and if the truck can get alongside. The balance of the service is at the Drivers health & safety discretion please.

If the site is not prepared or it is unsafe for our drivers to fit the tank, then a roll-off delivery will take place, so the tank can be installed at a later date.

The majority of State and Local Governments support the harvesting and banking of rain water and the installation of Poly Tanks. The requirement for government approval can vary between each and every local government areas and you may need to consult with your local government authority for approval processes particularly if the installation is greater than 10 Square meters on the average domestic zoned block of land.

You can find your local Government contact details here:

• NSW local council directory
• QLD local council directory

All Tanks proudly offered by DELUGE POLY RAINWATER TANKS are made of Virgin Grade plastic ( NOT RECYCLED ) that is approved to retain drinking water (AS4020). Local governments and water authorities may not give the tick nor recommend or allow the use of your harvested rainwater for personal washing such as showers etc, cooking, or for use as drinking water where there is reticulated / mains feed water available and or to your home-property. If this is the case there are filtering and UV water treatment systems we most certainly can offer which will allow you to use your harvested rainwater for human consumption once it’s sterile. Please ask us here at DELUGE or consult your local council or water authority.

The rainwater you harvest off your roofs and collection zones is your FREE rainwater and you are able to use this for any purpose you wish and wherever & whenever you like. That declared, if your water tank system is connected to the mains water system and utilises a “Mains Water Switching Device“ then there will be some specific restrictions. Again, please consult your local council and or water authority for more information.

It is recommended to use a basic automated pump so your tank water has the same pressure as mains water and or better. Once the volume drops inside the Tank so does the “ Head Pressure “ meaning by the time the water flows out of your Tank and along a 30 Meter hose etc- there is every chance a Kitten or a Chihuahua could pee harder … if we be so clear and truthful please. Trust us- you will want a basic Pump if nothing else. Not only do we offer a nice range of basic Pumps for use with your Tank, we also have a vast array to offer via our sister company. Please visit Pumps Galore here

The short answer is while it’s NOT mandatory you would be crazy not to purchase a Pump Cover as we offer at MASTER DEALER COST when ordering a Tank & Pump Package Deal. Most quality pumps come with an Electronic Automated Pressure Control Switch that should always be kept out of the inclement weather. While YES all Pumps and the Switch are “water Proof “there are NOT long-term weather proof and should be kept covered.

A Pump Cover can also help minimise general noise which is handy for neighbours and should the Pump be placed under you house or bedroom etc. ALL manufacturers recommend that you should protect your pump from the elements to keep warranty in order and clearly to extend the working life of your pump as a household investment. We offer a Pump Cover on a very special deal in any of 22 Colours to match you Tank. These Covers are offered at MASTER DEALER COST when ordering a Tank and Pump cover. This represents a saving of $40 ! Please see pump covers.

DELUGE POLY RAINWATER TANKS proudly distributes only QUAITY TANKS via two independent manufactures.

Please check with us at time or order regarding the best hose and or process for installation as different applications call for a different approach on many occasions

It is recommended you maintain your tank and system by regularly cleaning it of sediment build up by flush the floor during heavy rainfall etc. It best say every 3-4 months just take a look around all the Tank base and the fitting to make sure nothing is leaking or dripping away. In some cases where a large RURAL Tank is installed it may be best practice to flush the floor often and even every 4-5 years drain the Tank – hop inside and give it a good scrape and sweep out should sediment from gutters etc built up.
