How Rainwater Harvesting is the Need of the Hour?
In recent years, changing climate has made a great impact on our rainfall patterns. Part of a larger global picture, it is time to plan for the changes. As we are already experiencing tighter water restrictions, it is time to consider rainwater storage system implementation. Installing rainwater tanks is the simplest way to save rainwater which can save a home around 100,000 L each year just from their roof. It indirectly can be used to lower the water budget.
There are many reasons for which rainwater harvesting is necessary; out of which the biggest reason is a shortage of water. Though our planet is made of 75% of water, not all water is suitable for drinking as most of them are in the ocean. There is a constant shortage of water for drinking, industrial or irrigation purpose, even in those areas which receive plenty of rainfall. Modern rainwater harvesting system can help us fulfill this shortage of water.
Here are some benefits of rainwater storage tanks.
Easy to maintain
Utilizing rainwater harvesting system has many advantages to the community. It allows better utilization of rainwater as a good resource. Drinking water is not easily renewable, and rainwater storage system helps reducing wastage. System for collecting rainwater through tanks is extremely simple. The overall cost of the installation and operation is not only easier but also affordable. It requires little time and effort in their maintenance. In addition, the collection of water can be used in plenty of ways without purification.
Reduce water bills
Water collected through rainwater harvesting can be used for a variety of purpose, like laundry, irrigation, toilet flush, etc. This can bring a great reduction in utility bills for many families and small business. If we talk about industrial use, harvested rainwater can fulfill the need of many operations without depleting the nearby water resources or underground water.
It reduces the soil erosion in many areas allowing the land to thrive. Water can also be stored in tanks and cisterns and used when water supplies remain low.
Building rainwater harvesting system doesn’t take much requirement. Most rooftops act as a workable area for water collection which can be further directed to harvesting system. It also lessens adverse impact on the environment by reducing the use of fuel-based machines.
Rainwater is the purest form of water, free from chemicals unlike other sources of water on earth. This makes it suitable for irrigation and kitchen gardens. In fact, large reservoirs of harvested water are great for those areas which observe frequent forest fires during summers.
Reduce exploitation of groundwater
With the increase in population and decreasing natural water resources, the demand for clean, usable water has escalated at an alarming rate. It has many residential colonies and industries extract groundwater to fulfill their needs. As a result, groundwater has depleted and gone to extremely low levels in many areas, especially where there is huge water scarcity.
Reduces soil erosion and flood
If rainwater is collected in large storage tanks widely, it helps reducing floods in low lying areas. Besides, rainwater harvesting system helps reducing soil erosion and contamination of water due to pesticides and fertilizers. It led sot cleaner lakes, ponds, river and underground water.
Fulfills plenty of purposes
Our water consumption consists of many non-drinking functions, like flushing toilets, washing cars, laundry, watering garden, etc. All these can be fulfilled through collected rainwater rather than pure drinking water. Thus, water harvesting helps us save precious drinking or underground water.
Installation of rainwater harvesting system is very easy and affordable. Being a responsible human, we should make every effort to save our planet and its resources.
