Water Harvesting in Indore

The recent spate of floods in India has become a cause for concern for many in the stricken areas. While there are floods in some parts of the country, there are any parts that are facing acute water shortage.

I remember when I was a kid, there was a lot of rainfall (average was 44 inches per annum) and there was never a shortage of water. We would run in the monsoon rains and play. We’d make little paper boats (I got my grandmother to make me some) and watch them float into the flowing water. It was fun activity for all the kids in the neighborhood. I still have photographs that show that the water level in the Khan river was right up to the road level near Navlakha and that lakes like Pipliyapala, Bilawali and Sirpur, were full. So what has gone wrong now, that we are facing such water shortage issues. My personal opinion is that we have ruined the water supply supply system ourselves by the lack of planning and our greed to build and usurp land. Here is why:

About 40 years ago, I remember that the roads in Indore had little “Naalis” on the side. These were like the tiny drains on the side of the roads to drain the access water. These then dumped the water into the creeks (called Naalas) flowing in the city, which eventually met the Khan river or were emptied into the city lakes. Since there was a lot of open land, water would seep into the ground and replenish the underground water. And there were hundreds of thousands of trees, mainly in the catchment areas.

Now we have done away with the Naalis by the roads. The creeks are filled with dirt or are covered by land usurpers and homes have been built on those. Basically, we have cut the capillaries and arteries of the supply system. There are fewer open land slots. As a result, all the rain water is wasted. And of course, there are no trees left in the entire city -- let alone in the catchment areas. Can you imagine, even this year Indore received about 35 inches of rain and there is a short supply? Compare that with places in California or even the village of Anna Hazare, which only get about 7 inches of rain in the entire year, but is totally self sufficient in terms of water.

In California, there is a lot of greenery in the suburbs. The reason is that the government has mandated grey water be harvested and used for watering the grass and plants in the local gardens. Drains collect the rain water from roof tops and from the sides of the road and this is then sent to local creeks. Basically, water is harvested. Anna Hazare has done the same thing in his tiny village in Maharashtra.

It is still not too late. We can recover from this mess that we have created ourselves. All it needs is some collective will power and good leadership.
