Water is essential for life, and everyone should have access to it. About 71% of the earth\'s surface is covered with water. However, only 1.2% of the available water is drinkable. This 1.2% is a tiny percentage to ensure the world\'s population has access to drinking water. Furthermore, water contamination has reduced the percentage of water that is suitable for drinking. The scarcity of water is evident.
We should all make conscious efforts to prevent our natural resources from being depleted, which would ultimately endanger life on earth. Rainwater harvesting methods are the most effective sustainable practices to adopt. Let us understand the importance of rainwater harvesting, the available methods, and implementation steps.
What is rainwater harvesting and its methods?
Typically, a significant percentage of rainwater accumulates in the sea and ocean. However, rainwater in residential and commercial spaces often runs off the surface, going waste. Rainwater harvesting aims to repurpose rainwater. It involves collecting, storing, and using rainwater for various purposes. Rainwater can also replenish groundwater levels, keeping your garden or farm flourishing.
Rooftop and surface runoff are the most effective rainwater harvesting methods. The rooftop rainwater harvesting method places a catchment on the home\'s roof. It collects rainwater that would typically run off the roof and go to waste. The water from the catchment is channelled through pipes into a storage tank, from which you can directly use the collected rainwater.
In the surface rainwater harvesting method, permeable surface and percolation pits are created to collect rainwater that would typically run off the ground. The method prevents water logging, so you should strongly consider implementing it in your space.
How to set up a rainwater harvesting system?
First, you need to decide which rainwater harvesting method you want to implement in your home. Once you decide on the method, think of where to step up the system. For instance, if you wish to step up the rooftop rainwater harvesting system, opt for a rooftop made using the highest grade of grey cement, as it is uniform and durable, ensuring a secure step up.
- Place the catchment
A catchment is a piece of equipment that collects rainwater. It is available in different materials and sizes. Consider your rainwater harvesting requirement and other factors to buy a suitable catchment. As mentioned, place it in a secure spot on the rooftop or ground for efficient usage.
- Opt for a storage tank
Opt for a storage tank to store the collected rainwater. Like a catchment, storage tanks are available in several materials and sizes. Buy one that matches your requirements. Clean the storage tank regularly to prevent water contamination.
- Install pipes
Install pipes to ensure a smooth transfer of rainwater from the catchment to the storage tank. Make sure the pipes have no gaps or holes that leads to water wastage.
