With the Indian population facing major water scarcity and reports suggesting that 1.7 to 2.4 billion people will be living in water-stressed regions by 2050, there is an urgent need for systems that offer easy access to fresh water. A major solution to this problem is rainwater collection.
This sustainable process of collecting, storing, and using rainwater for drinking, washing, and irrigation saves money on water bills, reduces reliance on municipal water supplies, and, most importantly, helps conserve water. It is one of the most valuable and effective solutions to droughts and water scarcity without depleting any natural resource. Keep reading to understand the process of collecting rainwater and the different systems involved.
Process of Using Rainwater Harvesting Systems to Collect Water
The best rainwater collection system is one that features dual-intensity rainwater harvesting filters that help to collect clean water that can be used to recharge different groundwater sources. Find one at Rainy Filters, a company known for providing scientifically designed and precisely coordinated, all-in-one rainwater harvesting solutions. Here’s the working principle of the best rainwater collection systems:
- Rainwater, along with dirt and debris, flows by gravity through down-take pipes and enters the filter.
- Here, collected water starts rotating in an anticlockwise direction, flowing in angular motion into another filter element found in the lower unit. Note that collected rainwater flows at specific velocity and speed to create cohesive force at low intensity and centrifugal force at high intensity of rainfall. Regardless of the situation, the filter element does what it is intended to do: flushing out dirt and debris automatically.
- Next, rainwater passes through a drain outlet that further diverts clean water into a recharge well or sump through the clean water outlet.
Finally, collected clean water can either be used to recharge different groundwater sources or directly connected to pipes to be used for purposes like washing, cleaning, and irrigation.
Know the Different Types of Rainwater Harvesting
Knowing the different types of rainwater collection procedures can help you understand the systems better. Learn about the different processes carefully so you know which is best suited for you based on the rate of rainfall in your area.
The two types of rainwater collection procedures include:
- Rooftop rainwater collection wherein rainwater is diverted to an artificial recharge system or collected within a tank on the roof of a building or house.
- Surface rainwater collection wherein rainwater flowing away as surface runoff is collected and used for recharging aquifers using varied methods.
The best example of rooftop rainwater harvesting includes storing accumulated rainwater on a building’s roof directly into a storage tank. The storage tank is connected to drainpipes with exclusive filtering systems, along with a first flush device and mesh filter at the mouth. The tank also has a separate method for controlling excessive water overflow. This is the most affordable way to collect rainwater for washing and gardening.
Another example involves using different types of structures to replenish groundwater aquifers with collected rainwater on the rooftop. These may include:
- Transferring collected rainwater on a building’s roof to a filter or settlement tank through drain pipes. Further transferring filtered water to bore wells after settlement to replenish deep aquifers.
- Transferring collected rainwater to recharge pits or small pits featuring weep holes at regular intervals. Perforated coverings can be used to cover the pit’s top.
- Filling up dug wells with collected rainwater. However, it is important to ensure that the drilled wells are cleaned and desalted regularly to increase the rate of recharge.
Conclusion
The process of rainwater collection has been around for centuries, offering clean and filtered water for varied purposes.
