Rainwater Harvesting

Rainwater harvesting is the collection and storage of rainwater for reuse. Water collected through this method is used in gardening, irrigation, water for livestock and in some cases, even for drinking, if the tank is clean enough. Water is generally accumulated and redirected to a deep pit with percolation, where extensive refining and purification is done.

In today’s age, where global warming and water shortage is of extreme concern, rainwater harvesting acts as a blessing, offering many advantages to mankind. In most situations, it acts as a supplement to the main water supply. But in many countries, it is noticed to help hugely during regional water restrictions. With rainwater harvesting, summer times and drought seasons can be handled in a better way. It is an effective way to collect rainwater from areas that have excess rainfall and transfer it to nearby regions where there is a shortage.

The concept of rainwater harvesting is easy to understand as well as install and operate. It offers great financial benefits too. Rainwater is soft, and hence doesn’t require much detergent for washing, and has low running and maintenance cost.

In India, rainwater harvesting was first introduced in Andhra Pradesh, by ex-chief minister N. Chandrababu Naidu. He made it mandatory for every household within city limits of the state to have a percolation rainwater harvesting system, which assisted in increasing ground water level to a large extent. Tamil Nadu soon followed suit, making it a violation for buildings to deplete ground water. Within five years of implementation, Chennai saw a 50% rise in water level. Impressed by these results, many other states incorporated this system.

In Bangalore, Karnataka, the regulation of implementing rainwater harvesting came into effect in 2009. Existing buildings with an area of over 2400sqft, and upcoming ventures with over 1200sqft were made to install this system, failing which a heavy penalty would be imposed. According to a study done in 2010 by the Karnataka Groundwater Authority, Bangalore receives around 830mm of rainfall annually, which comes up to 66,400 hectare meters of water, of which 71% of water is getting wasted through evaporation and transpiration. Over 17,040 hectare meters of water was being drained along as sewage water, which could serve 23 lakh people (22% of Bangalore). When this study was done, Bangalore was facing a shortage of 11,226 hectare meters of water.

With these scary statistics staring at us, it is mandatory that we contribute in a significant way to ensure water is being collected through rainwater harvesting. Saran Developers is strongly playing their part by installing the best and most effective system of rainwater harvesting for Mulberry Woods. Not just because it is the law, but more importantly because they understand the importance of the situation we are facing.

An accommodation in Mulberry Woods will allow you to have the peace of mind you desire, ensuring there’s constant and quality water supply. You won’t have to worry about your part in saving water for the environment either.
