Water is the most valuable resource. Nature has given water to humankind and most people in dry continents like Australia and parts of the Americas know this too well. Remember the plight of California in the USA which continues to be plagued by the water woes for over two years now. Rainwater harvesting is one-way individuals and communities can address perennial water shortages. The process involves three stages – collecting water from the surface where large volumes of water gathers, storing it in a tank and distributing the water for outdoor/indoor use.
When should you consider investing in rainwater tanks?
The first step to consider ahead of an investment in rainwater tanks is the average amount of rainfall that is expected in your neighbourhood. You should also spare a thought to how you would use the water and how soon. Also depending on the average amount of rainfall, there are so many types of tanks available in the market among which slim water tanks are the popular ones which can be fitted comfortably in and around the house.
Recharging ground water supplies
Many state governments in Australia have issued statutory directions to owners of condos, apartments and other high rise structures to create rainwater harvesting facilities to recharge ground water supplies. Many homes and condos/apartments in this region are dependent on ground water supplies for everything except drinking water which is provided by the municipal administration. Groundwater is extracted with the help of deep wells or tube wells. Over exploitation of ground water leads to falling in the water table. Rainwater harvesting helps these communities to channelize the water collected at the rooftop into designated pits where the water is gathered to seep into the ground gradually. With hundreds of rainwater harvesting pits in a limited zone, the water table slowly rises to supply enough water during the summer days, in particular. Here is the small video which explains about the advantages of water tanks to fight against the scarcity.
Many new homes across Australia are required to have rainwater tanks
Given Australia’s dependence on rain for most of her needs, new homes in most states are now required to have rainwater storage tanks. Rainwater is also the purest water until it touches the ground. Therefore, rainwater collected on rooftops directly into containers can even be used for drinking and other human consumption. Some sources even claim that rain water properly collected and stored is even better than mineral water since rainwater carry no chemicals.
Runoffs into storm water drains
States like Queensland receive copious rains during the season. Large farm lands in this region will experience significant flows into the storm water drains. Potentially this can clog the stormwater drains adding further to the woes from the water itself. Rainwater storage tanks in such farms will bring multiple advantages of enhanced water availability during dry days and better storm water drains.
Your investments pay back through improved water availability
Considering that rain water is the primary source of water for most parts of Australia, your investment in rainwater, your investment in rainwater tanks will pay for itself in a relatively short space of time. The enhanced availability of water is another huge advantage that you will enjoy.
