Rainwater Harvesting

Rainwater harvesting (RWH) is a simple method by which rainfall is collected for future usage. The collected rainwater may be stored, utilised in different ways or directly used for recharge purposes. With depleting groundwater levels and fluctuating climate conditions, RWH can go a long way to help mitigate these effects. Capturing the rainwater can help recharge local aquifers, reduce urban flooding and most importantly ensure water availability in water-scarce zones. Though the term seems to have picked up greater visibility in the last few years, it was, and is even today, a traditional practice followed in rural India. Some ancient rainwater harvesting methods followed in India include madakas, ahar pynes, surangas, taankas and many more.

This water conservation method can be easily practiced in individual homes, apartments, parks, offices and temples too, across the world. Farmers have recharged their dry borewells, created water banks in drought areas, greened their farms, increased sustainability of their water resources and even created a river. Technical know how for the rooftop RWH with direct storage can be availed for better implementation. RWH An effective method in water scarce times, it is also an easily doable practice. Practical advice is available in books written by Indukanth Ragade & Shree Padre, talks by Anupam Mishra and other easy to follow fun ways

There is an urgent need to restore Najafgarh basin if the recurrent flooding and water shortage in Delhi and Gurugram have to be avoided in the future.

Here’s some news for nature lovers. A dirty drain in Delhi could well be on its way to becoming a bird sanctuary. The Najafgarh drain or nallah that flows through the northwest part of Gurugram is becoming a new habitat for the strikingly tall Greater flamingos, a rosy-white pink billed migratory bird as it passes through southwest Delhi.

I have a 300 sft plot in Gachibowli in Hyderabad. For the past two months, a cavity of 2 feet in diameter has formed. Rainwater is disappearing into this hole. I got this cavity filled up twice but a hole gets created whenever it rains. The bore is ten feet away and has casing upto 60 feet. I recently got the pump cleaned of mud and pebbles because water and soil had submerged the bore due to heavy rains. Now what is this hole that is forming? Is it a sink hole or a crack through which the water is disappearing?

An NGO comes forward to restore the forgotten kunds of Vrindavan which are not just historical marvels but are also freshwater sources.

Vrindavan, the small dusty twin town of Mathura in Uttar Pradesh, has a special place in the Hindu mythology. This is where Lord Krishna is believed to have spent most of his childhood and adolescence. The river Yamuna straddles through the town, a hot destination for thousands of devotees lining up for a dip in it every day. The place is also known for the rich saturated colours and messy revelry during “lathmar” holi where people hit each other with sticks.

A partnership between Biome, ACWADAM and WIPRO brought stakeholders together to map Sarjapur's aquifer.

The problem of Bengaluru’s water is well known. The demand for water tankers skyrockets during the summer months, when municipal and borewell water supplies run dry, and many of the city’s lakes, actually man-made tanks, lie neglected and polluted.

Indian scientists develop technology for harvesting water from dew.

We often notice dew drops on leaves, grass and some sloping surfaces in the morning hours. These dew drops can actually be a source of drinking water. 

A group of Indian scientists, working with experts from France, has developed technology for harvesting dew or atmospheric moisture for drinking water purposes and shown that it can be a cost-effective option in water-stressed regions like Kutch in Gujarat.

Most ground nearly everywhere is sloping in various degrees. Much more so in the hills. One way to easily and repeatedly catch rain water run off is to dig staggered contour trenches wherever possible. In forests, in grasslands, on marginal lands both government and private. The forest departments could do this in a big way instead of mindlessly growing plantations after plantations which in most cases fail anyway. This strategy will also help so much of the root stock in the soil to come up, we would need very little plantation after that. Grasses would come up in a big way too.

A few years ago, the landscape here was more countrified and quite distinct from the low rise neghbourhoods of Delhi dotted with its numerous parks and abundant institutional spaces.
