Importance of Rainwater Tanks Buying Guide

Saving rain

Australia is the driest inhabited continent and predictions are that the future is likely to get hotter and drier. So it’s all the more frightening that, per person, we’re the biggest water consumers in the world.

But drinking water is scarce. Of all the water in the world, only 1% is fresh water available for use. So it’s hard to justify that we waste so much of this precious resource on things that don’t really require good drinking water. Garden irrigation and toilet flushing, for example, apparently guzzle up around half the water we consume.

Using rainwater for these things, or recycled greywater from our baths and laundries, would make much more sense. Rainwater tank can be more effective if you know the right material of it.

Costs and considerations

If you’re interested in installing a rainwater tank, contact your local council, water supplier and health department (if you want to drink the water) first to find out which rules and regulations apply in your local area that could affect your decision.

You may need to submit a development or building application; or there may be restrictions on the tank’s location, colour, height and labelling; or noise regulations for a pump may apply. Your water supplier or a licensed plumber should be able to advise you on plumbing regulations, and your health department on issues about drinking rainwater and preventing mosquitoes breeding.

These initial inquiries should also establish whether you’re entitled to any cash rebates or bill reductions. Rebates can range from $150 to $1500 for the installation of a rainwater tank and depend on the size of the tank and whether it’s connected to a toilet and/or washing machine. Check with your local water or government authority

Outdoor, indoor or drinking?

Using the rainwater you collect for outdoor purposes only is the easiest scenario. Apart from the obligatory checks with your council and water supplier, you probably just need the tank supplier to install it and don’t need a licensed plumber if there’s no connection to the mains water supply.

If you’re allowed to connect your rainwater tank to the mains water supply, you’re likely to need a backflow prevention device so your rainwater won’t contaminate the mains supply if the water pressure changes suddenly and the water tries to flow backwards. Your water supplier may provide this free.

Many water suppliers and health authorities in Australia recommend you don’t drink the water you collect in a rainwater tank if you have access to mains water. But this is probably just to be on the safe side, because no authority can guarantee the quality of the rainwater you collect. You'll also be missing out on the benefits of fluoridated water if it's supplied in your area.

Roofs made of galvanised iron, Colorbond, Zincalume, slate and clay/ceramic or concrete tiles are OK for collection of drinking water. Taking part on how to install underground water tank or simplify rainwater metal tank can be accountable on getting potable water form rain.

Water saving tips

Cut down your time in the shower.
Install a water-efficient showerhead, and a flow regulator (restrictor) or aerator to taps to reduce the amount of water that comes out — your council or water supplier may offer rebates.
Install a dual-flush toilet (or put a brick in the cistern) to reduce the amount of water used for flushing.
Look for a water-rating label when buying appliances such as a showerhead, washing machine (a front loader uses less water), dishwasher and toilet. Together these four account for over 80% of indoor residential water use. The more stars on the label, the more water-efficient the appliance is, up to a maximum of five.
Only run full loads in the dishwasher and washing machine (unless it has a half-load program).
Fix all leaking taps.
Plant so-called ‘water-wise’ or native plants that need less water, and use mulch.
If you’re allowed to use an irrigation system in your garden, use a tap timer.
If you’re installing a new irrigation system, choose a drip system with a rain or soil moisture sensor.
For hand-watering, use a trigger nozzle or spray wand.

Looking for the Trends in Water Tanks

There are many new styles of water tanks available, with new innovations coming out all the time.  The most common types of tanks are the plastic or polymer tanks which have traditionally been round in shape.  These days, manufacturers are working with rectangular or square designs which are often much easier to place within a home and look much less intrusive.  These tanks are also available in a huge range of colours, so that they are able to suit any home colour scheme.

Steel tanks are still common, also, and these are usually lined with polyethylene in order to prevent corrosion.  While round metal water tank is still the most common shape, it seems that manufacturers are finding new ways to work with steel all the time.  Concrete water tanks are best if you need to locate your tank underground.  As they are load-bearing, they are great for placing under things such as driveways and entertaining areas.

One new innovation in water tank design is to design the tank so that it resembles a boulder or a rock.  This allows the tank to be placed unobtrusively within the landscape, so that the casual observer wouldn’t even know that it was there.  These tanks are also fantastic for environmentally sensitive areas.

In recent years, a major advancement in water tank design has been the development of the rubber water tank bladder.  The sheer flexibility of these means that they can be installed underneath a house, or even in the back of a vehicle.  Bladders are completely sealed and have an extremely high resistance to puncturing to ensure that they will not burst in the home’s sub-floor space.  Water bladders come with all of the necessary inlet and outlet valves.

Quality and Safety of Rainwater Tank

Rainwater that is captured and stored correctly is a safe, economical and sustainable source of quality water. Rainwater is as safe as any source of water, provided certain safety precautions are taken as part of water capture, storage and distribution. In fact some say that rainwater is safer than water supplied through mains or reticulated water systems. Our mains water is typically stored in dams, treated with chemicals such as chlorine to kill of bacteria and make it safe, and then pumped through a network of pipes throughout the community. Rainwater tank is the most safe storage for treatment of this water.

COUNCIL AND HEALTH DEPARTMENT RECOMMENDATIONS

Many Local Councils, State Health Departments and Industry Associations have either have developed, or are in the process of developing guidelines for use of rainwater harvesting systems. These guidelines have been developed to help optimise water quality. Key aspects of many of these guidelines are:


Incorporating Gutter Mesh Systems - to help ensure gutters do not become blocked with leaves and debris; to prevent mosquito breeding habitats


Fitting Rain Heads at gutter downpipes - to separate leaves and debris from the flow of water; to keep mosquitoes out of pipe systems to the tank (especially in "wet" systems)

Preventing the First Flush of rainwater from entering the tank - to reduce the amount of roof pollutants

Insect proofing all tank openings (inlets and overflow outlets) - to prevent mosquitoes breeding

Regular Tank Maintenance of the tank, catchment system, roof and gutters, inlets to ensure a safe supply of water. Desludging may be required every 2-3 years, and whilst regular disinfection should not be necessary, can be undertaken if preferred. See more products on rainwater tank Australia..

Rainwater Tank System: Useful Tips in Harvesting Rainwaters

Rainwater harvesting simply collects the rain which fall onto roofs, then stores it in a tank until required for use. When required, the water is then pumped to the point of use or to a secondary tank (header tank or break tank), thus displacing what would otherwise be a demand for mains-water. In the process, a volume of water is kept out of the storm-water management system, thereby helping to reduce flooding risks. Rainwater harvesting is not a new concept; however, over the last century its use has diminished with the availability of a clean, inexpensive and reliable water source through the mains supply.

More recently, water demand has started to exceed supply, and localised flooding has become an issue. Industry experts are now recognising the important role that rainwater harvesting (also known as rainwater recycling, and greywater recycling) has to play in alleviating both these problems. With strategic water planners looking to reduce the amount of water consumption per head going forward. Solutions such as rainwater harvesting will play a critical role. Rainwater is captured from the roof(s), and brought to a central point, via normal guttering and down-pipes, to enter a storage tank (frequently underground), where it is filtered on entry. A highly efficient and reliable submersible pump delivers the water to a service on demand. Depending on the circumstances a secondary tank (header tank) can be used to gravity feed the water to the point of use.

The size of the storage tank is determined by considering the amount of water available for storage (a function of roof size and local average rainfall), and the amount of water likely to be used (a function of buildings occupancy and function). It is very important not to over-size the rainwater tank too much. An over-sized tank may result in a lower than expected quality of water.
Considerations for fitting a rainwater collection system to an existing property

• The external drainage from the roof needs to be modified to bring the water to a central point.
• Access for the tank and excavation is required.
• Internal plumbing is usually required to be separated out from the drinking (incl. bathing) water from the non-drinking water (WC, washing machine & outside tap.)

Discover Your New Water System

The emergence of modern water pumping systems, domestic, industrial, factories, hospitals, has given great comfort and ease of use and consumption of the formation of community and daily water demand, and other businesses. Water is one of the basic needs of life. Humans can survive days without food - but not without water.

You must use great technology and modern facilities to pump water from beneath the earth and resources. During shadoof ancient water, supplied by land or by using the slider. This is a long lever pivot post located on the shores of two wooden upright. Other ancient water pump system is a wooden bucket. This is a continuous loop through the buckets of the pulley wheel, sawyer water filter which is believed to be used to irrigate farms and gardens of Babylon around 600 BC. Today, Rainwater tanks are very helpful for watering plants in farms.

Today's living water pumping from the ground up to take a new shape for a good place to live in the world. Submersible pump is one of the great discoveries that revolutionize the way people use water. This is a closed electrical devices.  Also known as utility pumps have been sold around the world. It has different functions like clear water and building residential and commercial waste water. Devices must be so large pump, is that it has a superior ability to force smoke as the air pressure does not depend on the outside. Water pump has a mechanical seal system used to protect the infiltration of water through the motor which can cause electrical shorts. In taking the newest water system nowadays, you must consider the quality and durable water tanks that can give you the user-friendly water system in your house.
