Rain Water Harvesting for Apartments: A Solution to Water Crisis


Water is one of the most essential elements to not just mankind, but to the entire existence of the earth. Mindless use and depletion of water sources around the world have brought us on the verge of a dangerous future, the one without drinking water. The recent news of Chennai facing acute shortage of drinking water and in some areas lack of drinking water is alarming for us. In fact, many cities in India including Mumbai, Hyderabad, and Jaipur are going to run out of water supply in a month or less.

This news isn't just an alert but is the stark reality that we have been ignoring for quite long. Statistics show us that by the year 2040, about 40-45% of India will be devoid of water. And in the face of such a crisis, we must do our best to make use of what we have. One such great way is to adopt the practice of rainwater harvesting.

What is Rainwater Harvesting?

Rainwater harvesting is the practice of setting up simple mechanisms to store water collected from rains to be used on site. What usually happens is that rainwater usually runs off, making its way either to the ground or in the drainage system of the area. In modern cities, the concrete and cement on the ground do not let the water to seep in, making it run off into drains.

This running water can be saved by strategically placing drainage pipes and storage tanks. Taking into consideration average conditions of rainfall and an average size of roofs of buildings, about 60,000 liters of water can be saved in a year, which is a lot considering that average yearly use of water in a household stands at slightly above 300,000 liters. This means that with simple changes in the structural build of a building, rainwater harvesting can save about 15% to 35% of yearly water usage depending upon the location.
