How well are our wells?

April 25, 2007

Open wells have a 5000 year history. They liberated humankind from

the tyranny of rivers and lakes. When humans found that you could

dig a hole in the ground and get water that must have been a Eureka

moment. This hole in the ground lined with stone came to be called a

well. Wonder why. We are on a journey to find out what happened to

the well. Do they exist? How do people use it? Are there new ones

being built? How can they be revived?  Do they fit into a city’s water

management strategy? Surprisingly their relevance seems to have

ben preserved and increased all over the country. We now have to

revive this technology quickly through a process of recharging

rainwater into the shallow aquifer.

The urban water paradox

April 24, 2007

Here we go again in this fair city of ours. A shower in April causes floods and a life is lost. Cars float in basements and people lose their homes. From the outskirts at the same time there is a huge water shortage and bore wells are going dry. People are queuing up for water and 1 pot of water  goes for Rs 2/-. Plus ca change, plus c’est la meme chose. (Go figure that one out:):))

There are 2 levels of intervention. At the individual level we must reduce

water consumption to the most efficient and harvest rain.

This will reduce the load on the citys water demand AND prevent flooding.

So how do we do this? Capture the rainwater into your sump tank.

Dig a recharge well 3 feet in diameter and 20 feet deep. Put all the storm

drain water into it.

Voila, the ground water levels

will go up and there will be more water in the 120,000 bore wells in the city and NO FLOODS

. .. and a paradigm to manage rainwater in a city looks like this
