Water Scarcity Causes Extinction of Life

Unsustainable extraction of freshwater and other human interference with the water cycle are the immediate causes of water scarcity within a river basin. Over-extraction has its most straightforward manifestation in the level of aquifers, underground reserves charged by the passage of water through soil and rocks. If withdrawals exceed the natural rate of recharge, the level of an aquifer will fall, eventually drying up altogether. In parts of India, the water table is believed to have fallen more than 300 metres.

Human intervention which degrades the quantity and quality of the natural supply of freshwater occurs in three principal ways. Undoubtedly, there are approximately 48,000 large dams in place around the world, with many more under construction. Dams alter the natural flow of a river, often improving water and energy security for some, at the expense of others.

Secondly, soil moisture is lost in land degradation that results from poor farming practices and deforestation. And thirdly, surface waters are polluted by run-off of chemicals used in farming and by untreated industrial and household wastewater in cities. This is an acute problem in less developed countries where environmental and sanitation regulations remain inadequate.

In many countries of sub-Saharan Africa, there is an additional category of “economic” water scarcity which is caused by too little human intervention. This occurs when natural supplies are sufficient to meet demand but fail to reach users due to shortcomings in distribution or storage infrastructure.

Being sustainable in water, we need to act now for water conservation. I think, dealing with rainwater conservation can help a lot in minimising the uses of potable water. Rainwater tank products are the usefull instruments in conserving water for treating rainwater. For having well manageable rainwater treatment, underground water tank can be the best design.

Underground Rainwater Tanks Benefit

Underground water tanks are very useful and practical. They prove to offer many benefits and uses for water conservation, sanitation, and as well as environmental purposes. Underground water tanks may be used for domestic septic systems as well as rural wells. They may also be employed to collect runoff storm water which may be used for other useful purposes such as gardening and cleaning. One of the best advantages of underground water tanks is the space conserved by simply installing the water tank in the ground. This provides extra or larger space which may be utilized for other purposes. Underground water tanks are usually built to endure various harsh environments. They may be made from polyethylene, fibreglass, or other highly durable materials. Underground water tanks are built to resist the permeation of gases and chemicals that are naturally present in soil and sewage wastes. This is very important to prevent water or soil contamination which may greatly affect the environment including vegetation, animals, and ultimately human health. Some underground water tanks features a variety of accessories like extensions and lid-riser combinations which makes self-installation easier.

How to choose the right model of Underground Rainwater Tank

When you have decided to purchase underground water tanks, there are some factors to consider before closing the deal. You must first decide on what type of material the underground water tank will be made of. As mentioned earlier, underground water tanks may be constructed from polyethylene, fibreglass, or even concrete. You should weigh very carefully the benefits and drawbacks of each type of production material. Second, you should choose the correct size for your needs. Usual sizes of underground water tanks are 700 litres, 4,500 litres, 5,500 litres, 7,500 litres, and 10,000 litres which is considered Australia’s largest underground water tank capacity. The third factor to look into is the manufacturer’s warranty. This is very important in case accidents happen or underground water tanks prove to be defective which is rarely the case. Lastly, you should look into the process of installation. You should try to compare the required excavation depth for installation. Installation cost should be considered. Some models may be self-installed by a handyman or experienced plumber.

Get Benefited With Rainwater Tanks

In the past, rainwater tanks were a common feature of the Australian landscape, but they’ve almost disappeared from our cities now. The majority of Australian households get their water from a reticulated supply. In the 1990s, 16% of households used a rainwater tank and for 13% it was their main source of drinking water.

In recent years, however, the long-lasting drought in many parts of the country and widespread water restrictions have drawn attention to water conservation issues and put rainwater tanks right back onto urban agendas. Many local councils, water suppliers and state governments have been encouraging residents to install a rainwater tank, usually with the offer of a rebate.

The potential benefits of installing a rainwater tank are plentiful, and you don’t need to live in a wet or tropical area to reap them. South Australia, the country’s driest state, has the highest rate of rainwater tank usage. More than half the households there have one, and for more than a third it’s their main source of drinking water., With a rainwater tank products, you’ll:
1. Collect most of the rain (around 80%) that falls onto the areas of your roof you have connected to gutters and downpipes into your tank. For example, if 10 mm of rain falls on to 100 m2 of roof you’ll ‘harvest’ about 800 L of rainwater. That’s about as much as an average Sydney household of three would use in a day if they made no efforts to save water. If they did, they’d get their consumption down to around 500–600 L a day.

2. Reduce your consumption of mains water and, in the long term, cut your water bill. Your water supplier may be able to give you an indication of the savings you can expect.

3. Lower your impact on the environment by reducing your demand on mains water as well as the amount of stormwater runoff into rivers and oceans.

4. ‘Harvest’ water that tastes better and is generally less salty, which is better for appliances and plants.

Important Things How Rainwater Tanks Are Effective

 Rainwater tanks are real boon to mankind. It is a dual blessing for nature and man as it works to the benefit of both. In a time where we have to preserve every possible resource, rain water tanks do just that. Before considering the size and type of rain water tank let’s find out how they work.

Rainfall is collected in water bodies and absorbed by the surface, even with all the development we have made, mankind still depends on rainfall to replenish water supply ever year. Rain fall is erratic – sometimes it is excessive and sometimes extremely scanty. To make sure we can retain as much of the rain water, rain water harvesting has added importance

Rainwater tanks system play a vital in role in rain water harvesting. A special system is installed in the house depending on a number of factors. When rain falls, special catchment areas of the roof retain the water. The rain water is then transported to the rain water tanks installed above the ground or below through special gutters installed around the roof area. The rain water is collected in the water tank through special pipes and is stored for use around the house.
