Rain water Harvesting is really the need of the hour. Water plays an important role for all living organisms, and the increasing scarcity of water urges everyone to save water for us and for our future. Conserving and storing rainwater for personal consumption and for future usage is called rainwater harvesting. Rain water is collected from rooftops and then re-directed onto reservoirs or storage tanks.
Though 2/3rd of the Earth is covered with water yet we humans struggle to conserve water on a regular basis. This is because only a small portion of this water is consumable. The water we consume is fresh water obtained from rivers, lakes, ground water, etc. However, water from seas and oceans is saline water which is not suitable for consumption due to the limited biological system of living organisms. Studies found that the ratio of fresh water to saline water is decreasing day by day. And the reason behind this could be an increase in population, growth of industries, deforestation, and many more. Thus, to increase the availability of freshwater, rainwater harvesting is a promising method to conserve water. Therefore many industries and organisations globally that have adopted this Rain water harvesting as it is a sustainable activity that is both beneficial to them and safer to the environment.
Different types of rainwater harvesting
Rainwater harvesting can be classified as 'Active rainwater harvesting' and 'Passive rainwater harvesting.
In Passive rainwater harvesting, the outdoor areas like driveways and landscaped gardens are sloped so that water can be channelised into the garden areas of the home.
Active rainwater harvesting is also known as rooftop rainwater harvesting where water is collected directly from the rooftop rainwater drainpipes and stored into underground storage tanks or sump pits.
How to filter rainwater?
The stored rainwater can be used for multiple purposes. But it should be purified before using for any other purposes. Some people just boil the rainwater for cooking purposes. Rainwater can be filtered and even used for drinking purposes as long as you have a clean catchment area and a proper filter. The below mentioned are types of filters used in the process of rainwater purification,
Charcoal filters - comprises layers of sand, gravel and charcoal
Sand filters- It comprises layers of sand, gravel and rocks
PVC pipe filter - it comprises differently-sized pebbles
Sponge filter - The water passes through 3 layers of sponge and sand.
After filtration, rainwater undergoes many processes like disinfection where the microorganisms are being killed, and after chlorination is done, ozonation and adsorption are done. After this process Rain water can be used as drinking water.
Storing and using rainwater reduces the use of municipality water. It helps to ensure the supply of water for a longer time. In addition to this, it also reduces water bills. The stored water can be used for washing your vehicles, laundry, watering trees, etc.
During government water supply cutoffs, rainwater can be used as a backup water supply.
It will reduce the chances of floods, erosions, and stormwater runoffs around the buildings. The rainwater is absolutely free to store, you just need to store it properly. Rainwater can be stored and collected in wells, cisterns, rainwater recharge pits, boreholes, and percolation tanks. It can be used for gardening, feeding livestock, rainwater irrigation, used for domestic use, drinking water, and recharging groundwater level. Nowadays sewage treatment plants also take place in textile industries.
