Chennai is known as "Detroit of India" since it is the automobile hub of the country. But faced with a severe water crisis, the auto firms are now coming up with newer ways to cut down on water consumption.

Automobile service centres in the city are avoiding the use of water to wash the vehicles. But this doesn't mean that the job is shoddy - vehicles are returned spic and span. What these service centres are using is called the dry wash method.

"For water wash, we spend a minimum of 50 litres of water per vehicle. On average, 35 vehicles are water-washed resulting in wastage of 1500 litres of water. Whereas in a dry wash, we use 700ml of water and 300ml of dry wash liquid. This mixture can be used to clean seven to eight vehicles," said Prabhu Jayaraj, service manager at a Royal Enfield outlet in Chennai.

"We are following the dry wash across all of our service stations in Chennai and intend to do so for the foreseeable future until there is some development in the water crisis," he added.

In the dry wash, compressed air is blown on the vehicles at high speed which clears the dust away. Then the solution is sprayed, after which it can be wiped clean. The method requires less time and manpower.

"If I want to wash my bike at home I usually waste a lot of water. Dry washing is good, especially as we are suffering a water crisis in Chennai. I am really happy to give my bike here for a dry wash," said Deshvar, a Royal Enfield owner.

With hardly any summer rains, availability of water is getting scarce and all four reservoirs that supply Chennai have run virtually dry. But the government says it is taking all the measures necessary to resolve the issue.

"We have seen protests in some areas. Protesters should not disturb the public. Our government is taking steps to solve the water issue soon," Tamil Nadu Water Minister SP Velumani said on Wednesday.

The acute water shortage has forced some schools to shut, companies to ask employees to work from home and hotels to ration water for guests.

The Kancheepuram district to the southeast of the city, which includes the factories of many foreign automakers, saw groundwater levels deplete more than 6 ft (1.88 metres), or three times the state average, to about 20 ft during the year ended May 2019, the data showed.

Automobile service centres use dry wash to cut down on water use in parched Chennai

In the small village of Bangarampettai, 20 miles from country's manufacturing capital Chennai, about 150 people last month "captured" a water tanker, breaking its windscreen and deflating its tyres before handing it over to a nearby police station.

People living on the outskirts of Chennai&nbsp;are blocking roads and laying siege to tanker lorries because they fear their water reserves are being sacrificed so city dwellers, businesses and luxury hotels don't run out.

"Private tankers have fitted more than eight bore wells in our village and are indiscriminately extracting thousands of litres of water every day," the Bangarampettai villagers wrote in a letter to a government official in the region a day after they stopped the tanker.&nbsp;

Bad water management and a lack of rainfall mean that all four reservoirs that supply Chennai&nbsp;have run virtually dry this summer. That has forced some schools to shut, companies to ask employees to work from home and hotels to ration water for guests.

Other&nbsp;cities, including the capital New Delhi and technology hub Bengaluru, are also grappling with serious water shortages.

But the problem is most acute in Chennai, where local tensions have been inflamed by the Tamil Nadu state government tapping wells normally used for agriculture and villagers'&nbsp;daily needs.

In their letter, the Bangarampettai residents said they had petitioned government officials, including the district's top administrator, several times, but the tankers keep returning. "We don't have water in one of the two water tanks in the village now because the private tankers have been extracting water day and night," said S Arul, a local signboard painter.

Groundwater levels in Chennai's neighbouring districts, Thiruvallur and Kancheepuram, fell at a faster rate in May than the state average in districts excluding Chennai, data from the state's public works department showed. Data for Chennai district has not been made public.&nbsp;

The Kancheepuram district to the southeast of the city, which includes the factories of many foreign automakers, saw groundwater levels deplete more than 6 ft (1.88 metres), or three times the state average, to about 20 ft during the year ended May 2019, the data showed.

There is no sign yet that the factories are having to reduce production because of the shortage.&nbsp;

Dry lakes

M Jeeva, 27, who runs a hardware store near Bangarampettai, said he followed trucks taking the village's water back into the city and found they mostly supply hotels and companies.

Two of the biggest lakes in Thiruninravur, the nearest town to Bangarampettai, are dry. When Reuters visited, a fishing boat could be seen grounded and abandoned while children played cricket in the middle of the dry lakebed.

In Poochi Athipedu, another village on the city's outskirts, a local landowner S Ramesh allowed private tankers to sink bore wells and extract water, leading to protests by the local community.

Ramesh said he was paid up to 500 rupees ($7.20) to fill a 12,000-litre water tanker, but stopped selling water after the protests.

Officials, though, say there is no reason to be worried. "Water is being extracted only from regions within the district where there is sufficient water," said Mageswari Ravikumar, Thiruvalluvar's&nbsp;top administrative official, adding that the district administration had stopped some water tankers that were extracting water illegally.

Two state government officials said residents in at least three other villages in the district - where much of the population relies on cultivating rice and sugar cane - blocked roads in protest over worries about falling groundwater levels.&nbsp;

And N Nijalingam, president of the South Chennai Private Water Tankers Association, confirmed some tankers have been chased away, while others have had confrontations with angry crowds on the city`s outskirts.

More than 5,000 water tankers have been travelling within a 35-mile (55-km) radius of the city to pick up water for Chennai, he said.

Haphazard development

Like many Indian cities, Chennai`s growth over the past 20 years has been rapid and haphazard. Its population will have likely more than doubled to 10.7 million by 2020, from 4.6 million in 2011, according to the United Nations.

The Chennai municipality provides more than half of the city`s water through piped supplies and tankers hired by the authorities, with the rest handled by private firms, according to Sekhar Raghavan, director of the Chennai-based Rain Centre.

Across the city's poorer suburbs, there are many signs of the shortage. In Shanmugapuram, a suburb in the Thiruvallur district located right beside one of Chennai's biggest water sources, women of all ages holding blue and green plastic pots shouted slogans demanding water last week outside a government office.&nbsp;

At a water distribution point in North Chennai, people crowded around taps, with some arriving on the three-wheeler auto-rickshaws loaded with as many pots and buckets as they could carry.

The state government last decade made it mandatory to install rainwater harvesting structures in new buildings, but locals say it hasn`t been properly adopted.

Harsha Koda, Coordinator of FOMRAA, a residents association in the city, said people in his locality were paying up to 70 per cent more to buy water from private water tankers.

Residents in Chennai say the waiting period for city corporation-run water tankers, which deliver water at a lower price, is as long as 25 days.

"I paid 1,700 rupees for a 12,000-litre water tanker two days ago because the tanker had to travel 50 km more to fetch water," Koda said, adding that he previously paid 1,000 rupees for a tanker.
