I assume Cross is a native Chinese just trying to understand why the GOI does not implement some rules to control the water pollution issue, I don't think he means any ill will but just trying to understand why certain things don't work the same way as (call it cultural differences). English is also not everyone strong language so lets take it easy.
You will definitely know a troll when you see one, I am pretty sure Cross is not under that category.

Not to cause a flame, but I can say for a fact most of the travelers that worked with me (Singapore, UK, US) have came down with diarrhea during their trips to India.
Some of it was due to the water but I think most of the cases were because of the food, the spices used in the food preparation though tasty is not suitable for all traveler, woe befall the newbies who consume the curries without the yogurt
Most of long term stayers typically adapt after 2 weeks so any water / food borne bacteria will not pose any issues.

You are right on... most of the indigestion is due to the copious amount of spicy and oily food that most tourists end up eating at the restaurants. Many don't realize that homecooked Indian food is much more simple and plain... just a tiny hint of spice and oil. Unfortunately there are a very few restaurants who would serve food like that in a public place.... you need to know the city to find such places.Not to cause a flame, but I can say for a fact most of the travelers that worked with me (Singapore, UK, US) have came down with diarrhea during their trips to India.

Not to derail the thread, just thought I put a funny incident that happened while I was working in Hyd relating to the local food.
My Gf came to visit me during my stay and I brought here to a pretty posh local restaurant (Serengeti) to sample the local delights, being new she poured tons of curry on the biryani and ignored what I said about putting the yogurt too. It took 20 mins for her face to turn green, local spices are not to be messed with.
But the best local delights as you said are definitely simple, the Biryani at Persis Restaurant or at the Chamina area is one of the best I had for sure.

Jeez, yet another reason to go to war.
Here's what you do in hot countries with water problems:
You pump it from the sea into a hot desert area.
There in the desert you evaporate it in thick black plastic cones that capture both fresh water and salt+minerals.
Salt+minerals get collected by workers, aka: new good jobs..
Put some plumbing on many of these plastic evaporation cones, and voila: one less reason to go to war.
If you do this on a large scale, you'll even have less reasons to go to war over food, too.
I had this idea a few years ago, advertised it in various forums, but it hasn't been picked up yet

India's water crisis' cheap solution: Waste water recycling
Where will India get its water from in the coming years? The water challenge is already grave and could get graver. By 2050, for instance, it is estimated that demand would go up to 1,180 million cubic metres, 1.65 times the current levels, a situation that would be made worse by fast dwindling fresh water resources. That's why desalination removing salt from seawater to make fresh water is increasingly catching the fancy of administrators. Two of India's most industrialised states, Tamil Nadu and Gujarat, are the keenest among the lot. A water-scarce Tamil Nadu, already running one desalination plant, is working to complete a second plant and planning for the third. Gujarat is also said to have desalination plans.
"The industrial sector's preference toward desalination is expected to increase with the growing demand for processed water. Many of the coastal municipalities are also keenly looking to invest in desalination," says consultancy Frost & Sullivan's environment technologies expert Sasidhar Chidanamarri. India, along with the US and China, is seen contributing quite a bit to a global doubling of desalination capacity between 2010 and 2025, says Frost & Sullivan. Of course, the biggest contributor would be West Asia, which would by then account for half the world capacity.
But the question that experts are increasingly asking, at a time when a draft water policy is being debated, is this: is desalination the best option?
Treating Waste Water
Countries the world over, while being bullish about desalination, are equally bullish about other means, notably waste water recycling. Not India. Only about 31% of municipal wastewater can be recycled. That would be more than 75% in China. In a recent working paper titled "Water Supply in Chennai: Desalination and Missed Opportunities", researcher Sridhar Vedachalam of the New York State Water Resources Institute at Cornell University wrote that "desalination may provide a reliable supply of water to a city with chronic water shortage, but it is hardly the best option for more than one reason".
"Desalination, while being a source of fresh water, does nothing to address the challenge of managing those extra million litres of wastewater," says Vedachalam. "Recycled water, on the other hand, solves the twin problems in a single shot."
When Tamil Nadu launched its first desalination plant in 2010, at Minjur, 27 km from north of Chennai, the benefits seemed apparent. Tamil Nadu's water challenge is historically well chronicled. Now, it houses 6% of the country's population but only has 3% of its water resources. Also, Tamil Nadu gets an annual rainfall of 792 million metres versus the national average of 1,250 million metres. The per capita availability at 800 cubic metres in the state is just a third of the national average.
"Why not go further and pick a more futuristic technology one that addresses problems of water supply and wastewater management, is ecologically compatible and lead the way for the rest of the country and even the world. Reuse can be implemented anywhere (not just in coastal areas) and, therefore, has a much bigger market allowing future improvements in technology and reduction in cost," says Vedachalam.
Rs 25/litre Difference
For Sam Yamdagni, managing director of the Indian arm of the $3.8-billion US-based water technology company Xylem, there is no way waste water treatment can be missed. "Even when you are creating water through desalination, you have to look at creating waste water treatment because again you are going to generate waste."
But ecological compatibility isn't the only reason. There's a compelling cost reason favouring waste water treatment.
R Raghuttama Rao, managing director of Icra Management Consulting Services, points out those cases. He says, "Desal is more expensive upwards of Rs 50 per kilo litre compared to Rs 25-35 per kilo litre for recycled sewage. Desal requires more power and is energy intensive." Chidanamarri estimates the capex for desalination plants to be two-and-a-half times that of a conventional treatment technology. "Clearly, desalination is an expensive proposition. And the government is contemplating to offer tax incentives for industries which would help them in recovering the high costs." (He also points out, though, that improved technologies have over the years brought down the cost of water from desalination.)
Given this, Vedachalam had argued in his analysis, "Reliance on such expensive technology [desalination] does not augur well for a city [Chennai] that already does not collect revenues that match its expenses." A report in 2005 estimated that only a fifth of the water sold in Chennai was metered. The rest of the country may not be vastly different in this respect.
Data supports this view. According to a presentation available on the Ministry of Urban Development Website, the average cost of wastewater treatment is Rs 4.5-6 a kilo litre, and this can be used for agriculture or gardening purposes. If treated for drinking use, the cost does jump to Rs 12 but this is still far less than what metros in India spend to bring potable water to its residents. Here are the numbers: from Rs 20 per kilo litre in Delhi to Rs 40-60 in Chennai.
Perception Problems
The other significant side of the story is India's growing demand for water. Nowhere is this as evident as in the industrial sector, which now consumes about 50 billion cubic metres of water annually. That figure will jump to 120 billion cubic metres by 2025, says Frost's Chidanamarri.
Given this, going in for waste water recycling aggressively should be a no-brainer. But that's not been the case. There's a reason why the actual scope for use of recycled water is far less. "From a mindset perspective, people are more ready to drink desalination water relative to treated waste-water," says Icra's Rao.
Rajiv Mittal, managing director of water treatment company VA Tech WabagBSE 1.44 %, agrees about the mindset issue. "In Singapore, the prime minister of Singapore campaigned for safety of recycled water for drinking and he was the first one to use this." Mittal says in Singapore they call it reusable water, not waste water.
Icra's Rao says indirect potable use (where recycled treated sewage water is pumped into water bodies/river streams which is conventionally treated again) is becoming more popular. Singapore already does this. Bangalore was planning such a project but that has not happened so far, he says. But the low-hanging fruit in waste water isn't in challenging strong perceptions of the people but actually is in the industrial sector. Already, there are examples of treated sewage being used by industries in India. In Chennai alone, wastewater is supplied to companies such as Madras Refineries, Madras Fertilisers and GMR Vasavi Power for reclamation and reuse.
Thirsty Industry
The industrial potential is already evident through desalination. VA Tech's Mittal knows that well. His company is the one building the second desalination plant in Chennai, some 45 km away at Nemelli. It is eyeing a big opportunity in the desalination space. Between 2005 and 2010, about 63% of the 5.3 lakh cubic metres per day of desalination capacity was accounted for by the industry. The municipal segment accounted for the rest.
He reckons the way to go about it is this: waste water treatment for industrial use and desalination for domestic use. Europe does it well. It recycles about 60% of the domestic sewage generated and it is consumed for non-potable applications such as boiler feed water, cooling tower, landscaping, gardening and flushing.
Anand Chiplunkar, a director of urban development at the Asian Development Bank, says, "Wastewater treatment can generate revenues and thereby not only reduce the operating and maintenance costs but also recover capital costs [when recycled to industries]." Therefore, he says, "it has the potential to attract private sector investments in properly structure projects".
Rao says, "Waste-water recycling would be particularly attractive to address requirements of industrial use, if the demand is concentrated [eg SEZs]." That's one way to meet India's growing water needs.
