Let's look for some fluid solutions
Mumbai has both a flooding problem during the monsoons and periodic water cuts. The solution should be obvious: water harvesting, as Chennai is doing with great results The key benefit for Mumbaikars from rainwater harvesting will be in reducing their dependence on the ubiquitous water tanker

R AINWATER HARVESTING is one of the keys to making Mumbai a more livable city.
As Mumbai continues to grow, bringing water to the city from outside becomes increasingly difficult. We are running out of sources to tap into. As competition for this limited resource intensifies, people outside Mumbai are not going to willingly give up their water for us. Rainwater harvesting is a solution that is literally in our backyard.

How much water can Mumbai harvest? On long-term average, Mumbai gets about 2400 mm of rainfall a year. Taking an area of 437 sq km gives us about 2800 MLD (Million Litres per Day) over the course of a year. So depending on how serious we are about it, we can get anywhere from zero to 2800 MLD of our water requirements from rainwater harvesting. Compare this with Mumbai's current water supply through BMC of about 3500 MLD, of which a fifth or more is lost in leakages, and another 1000 MLD shortfall, which is met from other sources. This should show us that rainwater harvesting has serious potential.

The key benefit for Mumbaikars from rainwater harvesting will be in reducing their dependence on the ubiquitous water tanker. With rainwater harvesting in the rainy season, people should be able to meet their requirements along with the BMC supply In fact several ‘ear . ly adopters' of rainwater harvesting report that the recharging is continuing to give them water even in summer months. From the macro-view, more water from rainwater harvesting means less water needs to come into the city from outside, reduc ing costs, energy consumption, and increasing sustainability and dependability. As more and more people harvest rain, there is going to be a perceptibly positive effect on flooding - something surely no one will complain about.

We must recognise the limitations of the city administration in water supply Despite the talk . of a world-class city and provid ing 24-by-7 water, BMC cannot conjure water out of nowhere. As the city's needs grow, it becomes ever harder to find new water sources and transport the water to the city As a part of the . solution, BMC should aggressively promote rainwater harvesting and legislate it after appropriate preparation. Businesses must recognise that rainwater harvesting is a sound investment for ensuring Mumbai's future. It must be implemented in offices as a matter of course. Housing societies must be helped in implementing it. Asian Paints has set a great example of rainwater harvesting and sound water management - and it has added to its bottomline.

How are other cities faring? In October 2002, the government of Tamil Nadu passed an ordinance making rainwater harvesting compulsory for all residences and giving people a year to construct the facilities. This was after the situation got extremely bad - in 2002, Chennai was getting a jaw-dropping low supply of 194 MLD from the municipal corporation compared to the requirement of 790 MLD. 2004 was a bad monsoon year and 2005 and 2006 were good years. Nowadays, Chennai is seeing rising groundwater levels. For example, a study by Chennai Metrowater showed that between June 2005 and 2006, the average groundwater level in the city was up by 2.5 meters, thanks to water harvesting. The trend of falling groundwater levels has been reversed. Chennai now is better prepared to face a drought year. According to Sekhar Raghavan of the Chennai Rain Center, saline water intrusion, a big problem in coastal areas of the city has come down dramatically, with the level of dissolved salts falling by as much as 80 per cent in some areas- one of the big success stories of compulsory rainwater harvesting. This is something Mumbai also stands to gain from harvesting rainwater. Chennai is also experimenting with largescale desalination, but the cost of water produced by that technology is very high.

Bangalore continues to grow rapidly but it has few water supply choices left. There is only so much water it can extract from the Cauvery and the interstate fight with Tamil Nadu over those waters make that hardly a reliable source. Thus Bangalore too needs to adopt rainwater harvesting and water recycling in a big way or suffer Chennai's painful experience.

There is every reason to make rainwater harvesting compulsory in most cities, including Mumbai. The water crisis is real, and rainwater harvesting is an essential component of the solution. So many housing societies and companies have already implemented rainwater harvesting successfully There is . no dearth of organisations in Mumbai that will offer support in implementing it. Asian Paints runs a Total Water Management Center at its Bhandup office that is free and open to everyone. The company says it has helped people harvest 100 million litres of rainwater to date. Eureka Forbes also offers free rainwater consultancy and has helped many housing societies in setting up their rainwater harvesting systems. L&T Powai, Tata Institute of Social Sciences, St.Catherine's Home, Andheri to name a few are successfully using harvested rainwater. A listing of groups that offer consultancy and design can be found at http://tinyurl.com/2lca98, along with examples of successful rainwater harvesting. With the kind of rainfall Mumbai gets, it is only commonsense that we use the water judiciously and don't seesaw between floods and shortages.

There are some other aspects of the water problem that need to be looked into. One is wastewater recycling, which has enormous potential. There are already working examples that show its viability The other is water con . servation - the best way to implement that is through pricing water at a level that encourages people to conserve. But the pricing should be by slabs, ensuring supply to everyone irrespective of their ability to pay .

A big deal !

Through various circumstances, I ended up writing an article for the Hindustan Times, Mumbai edition. Op-ed no less ! It appeared on September 14th Friday.

http://epaper.hindustantimes.com/artMailDisp.aspx?article=14_09_2007_013_001&typ=0&pub=264

It was a lot of fun getting together the material for the article, though it was scary. I talked to a bunch of people in the course of doing it. Also I kinda cheated in writing it as if I was a Mumbaikar. But hey, I can live with that. Overall I think the article was somewhat unremarkable and didn't show a lot of insight, but given the constraints, not bad.

This is quite a big deal for me. Since I like reading and writing, I have always nursed a hankering to write in public. Its great to be able to fulfil that.

Travels






The Hotel de l'Orient in Pondicherry



I've been travelling a little bit here and there and its keeping me happy.
I went to Thane (suburb of Mumbai) in August for a couple of days on work.
Then we went to Kalahasti late August.
Last weekend I was in Timbaktu and midweek this week I was in Pondicherry/Auroville for a workshop kind of thingy. Pondy was definitely the highlight and I want to keep going back. The French town is gorgeous more so because its a sight you don't see anywhere else in India (perhaps Goa). I picked up an interesting music CD this time called Pondy groove, a crazy mishmash of French, English, traditional Indian, fusion and whatever else.

Timbaktu was remarkable for the amount of water I saw this time including the huge and amazing Mushtikovela tank. I had the privilege of seeing it reach to 6 inches of the full tank level (FRL for the cogniscenti) and a couple of hours after I left, I was told that it overflowed.

PS: ***@!#$#*(&&(*&&)Q#R*&(*&(@&#(& Tamilians for changing the name to Puducherry. I am composing in mind a rant against Tamilian-ness, that I will post to the Written Word.

Remarriage !!







For reasons which remain very unclear to me, Priya's family has been very keen that we go to Kalahasti near Tirupati and redo the tying of the knots there. This finally happened on 26th August (a couple of days before our anniversary). Her parents were also there. Overall quite an uneventful experience. The diety is quite interesting -- it is a shivalinga but a very svelte tall thin version. Both at Kalahasti and Tirupati the chamber where the diety is kept has a certain mystical feel to it. There is a background chant and the chamber is deeply recessed with lighting and I do get affected by the atmosphere which is quite rare for me. At Kalahasti we were there at the time of the aarathi cermony which is a small spectacle with lots of loud musical instruments including a chap bashing together two brass plates creating a tremondous din, and overall again creating a certain atmosphere.
There was an interesting side-episode where the grand pujari, the senior person in the hierarchy, showed some interest in our case dismissing any possibility of 'dosha' (which is why we had gone there), and quite accurately telling Priya's parents that if we didn't have children it was because we didn't want them.

Photos are at the hotel where we stayed, cameras were not allowed inside the temple.

Balcony kitchen garden








Our balcony garden expanded significantly courtesy Priya's mom. There is a creeper that we planted (broadbean) that is growing wildly. An interesting side effect from applying our own compost is that every pot has sprouted one or two tomato plants. Overall, it gets me great happiness to see a minor jungle happening on our balcony. Now we have a few edibles happening there that are nice. We planted broccoli. One of them gave us the edible flower, but before growing much the flower seems to be 'blooming' which is disappointing and leaving us with the tough choice of eating it now or letting it grow more and become less edible. The tomatoes are also growing nicely and we have a coriander pot that has been through one harvest already. Palak is in the offing...

Varalakshmi Vratam at home




This year we performed the puja at our home. Priya did everything on her own, including reading the mantras and setting up the goddess. She cooked garelu, sakkarai pongal, kheer. And she finished doing all this before her sister, mother and mother-in-law in their respective homes. She was feeling quite smug.
