Life moved at a snail’s pace in nearby Leh town at -14.2 degrees Celsius. It was the coldest night of the season so far in Leh and Kargil. Kashmir is currently under the grip of Chillai-Kalan a 40-day harshest period of winter when the chances of snowfall are most frequent and maximum and the temperature drops considerably. It ends on January 31, but the cold wave continues even after that in the valley. The MeT office said there was possibility of light rain or snow at isolated places, especially in the higher reaches, today and tomorrow. Normal life crawled at -20 degrees Celsius in Kargil in the cold desert of Ladakh even as temperatures remained several degrees below the freezing point elsewhere in the Kashmir Valley. Light rain or snow at isolated places over the next 48 hours may add to the discomfiture, the weatherman said.Srinagar, the summer capital of Jammu and Kashmir, had a low of -3.9 degrees Celsius, a MET department official said. The mercury in Qazigund in south Kashmir settled at a low of -4.4 degrees Celsius. The nearby town of Kokernag recorded a low of -2.5 degrees Celsius. Kupwara in north Kashmir quivered at -3.6 degrees Celsius. The world famous ski resort of Gulmarg reeled under freezing -6 degrees Celsius. The night temperature in Pahalgam, which also serves as one of the base camps for the annual Amarnath Yatra, had a minimum of -4.5 degrees Celsius.
Over 100 people were killed and around 180 injured after a high-velocity dust storm followed by thunder showers wreaked havoc in parts of Uttar Pradesh and Rajasthan on Wednesday night, leaving behind a trail of destruction.Trees and electricity poles were uprooted and mud houses collapsed in the high-intensity squall, officials said on Thursday.Expressing sorrow at the loss of lives, Prime Minister Narendra Modi on Thursday directed officials to coordinate with the States to ensure speedy relief and rehabilitation of those affected.“Saddened by the loss of lives due to dust storms in various parts of India. Condolences to the bereaved families. May the injured recover soon,” the Prime Minister’s Office tweeted quoting Mr. Modi. In Uttar Pradesh, at least 70 people were killed and 83 injured, with Agra accounting for the maximum casualties — 43. Three persons each died in Bijnore and Kanpur Dehat, and two each in Saharanpur, Hamirpur, Kanpur Nagar and Mirzapur districts. One casualty each was reported from Bareilly, Pilibhit, Chitrakoot, Raebareli, Unnao, Mathura, Amroha, Kannauj, Banda, Kanpur, Sitapur, Sambhal, Etawah, Allahabad and Rampur.In Rajasthan, 16 people died in Bharatpur district, 10 in Dholpur and five in Alwar, while over 100 were injured in the storm that hit the region around 7 p.m.The worst period lasted about 45 minutes, according to reports from Dholpur, but the extent of the damage was known only in the morning.Another storm comingThe Meteorological Department has issued warnings that another dust storm may hit parts of Uttar Pradesh and Rajasthan in the next 48 hours due to the cyclonic circulation formation in the region.DMs on high alertUttar Pradesh Chief Minister Yogi Adityanath has issued an advisory ordering all district magistrates to be on high alert. He has asked the district officials to calculate the losses and provide compensation to those affected urgently, a government spokesperson said.State Chief Secretary Rajive Kumar has instructed the Commissioner of Agra division to ensure that relief is distributed in the affected areas by Thursday evening and senior officials visit the injured in hospitals, said U.P. Information Department principal secretary Awanish Awasthi. Power supply was cut off in many areas as the squall uprooted trees and snapped electricity cables. Officials said it was being gradually restored.Rajasthan declares natural disasterIn towns, the storm triggered traffic snarls and in rural areas there were reports of crops being damaged due to hailstorm. Farmers lost cattle and poultry. U.P. Relief Commissioner Sanjay Kumar said 160 head of cattle were lost.Rajasthan Home Minister Gulab Chand Kataria, who also holds the Disaster Management and Relief portfolio, said the storm has been included in the category of natural disasters for the first time in the State and funds to the tune of ₹2.55 crore have been sanctioned to the affected districts.Financial assistanceThe next of kin of each deceased in Rajasthan will get financial assistance of ₹4 lakh from the Chief Minister’s Relief Fund.Chief Minister Vasundhara Raje expressed grief over the calamity and directed the Ministers and officers concerned to begin the relief work immediately and restore utilities.Power discoms have launched action on a war-footing to restore electricity supply in the affected areas, while the administration has ordered a survey of damaged properties.Major destruction was reported from Alwar district, where trees fell and power cables snapped, plunging a number of areas into darkness. In Dholpur district, relief camps have been opened for the villagers whose houses were destroyed.

Nova Scotians may be test-driving a new type of paving projectthis summer. A mix of recycled rubber and asphalt is expected to be laid downon the Granton Road in Pictou County this year as part of a 3.3kilometre pilot project put forward by Nova Scotia’s Departmentof Transportation and Public Works and Michelin Tire of Canada. “We are looking for new and innovative ways to make our roadsstronger and to reuse materials readily available,” said RonRussell, Minister of Transportation and Public works. “This isjust one more way that we are building Nova Scotia’s future andinvesting in our province.” “Michelin is very pleased to work with the Department ofTransportation and Public Works in bringing rubberized asphalt toNova Scotia roads,” said Doug Cassidy, Michelin Granton plantmanager. “It’s a significant environmental project that couldmake a big difference for Nova Scotians.” Michelin will contribute to costs associated with the rubberizingof the asphalt including the recycled rubber, consultants andspecialized equipment; the government of Nova Scotia will pay forthe bulk of the contract. The end product is expected to be more durable than conventionalasphalt treatment, and better able to withstand cracking. Thiswill be the first use of rubberized asphalt on provincial roads.The product is used across North America. A tender for the paving contract was advertised today, March 10.It closes Friday, April 2. Work is to be completed by Aug. 31.

The MineSight Implicit Modeler reduces from days to minutes the time it takes to model complex veins. Now geologists can work faster and with greater precision, modelling complex veins directly from drillhole data. Add MineSight’s surface and solid Boolean tools and geologists can easily handle complex veining systems, including bi-furcating and crossing veins. “MineSight has taken a leading role in developing innovative solutions to help geologists spend more time being geologists,” says Mark Gabbitus, Senior Product Manager-Geology & Operations.“I remember when I was a geologist in Australia’s Northern Territory, working on a narrow vein gold mine. I think about how many hours I used to spend modelling these types of features. Now I can do in minutes what used to take me days.”Since its release in 2013, MineSight Implicit Modeler has been lightening geologists’ workloads around the world.“Implicit Modeler was actually one of the best things that ever happened to us,” said Raza Parvez, Senior Geologist for Canada’s Atrum Coal.“I think MineSight Implicit Modeler is really going to revolutionize how complex coal models are built,” added Dustin Meisburger, Senior Mining Engineer at Canada’s Peace River Coal.Implicit Modeler is using logic originally developed for coal seam modelling, or true thickness modelling.“This is something we have applied to the complex coal deposits in British Columbia, Canada, for years and the functionality was recently enhanced by adding the logic to our Implicit Modeler,” said Gabbitus. “We can use exactly the same logic for veins as well to ensure that the hanging wall and footwall surfaces do not cross.”Recent enhancements to MineSight Torque and MineSight Implicit Modeler have made the selection of data points in veins much easier. The ability to output solids as well as surfaces makes the generation of the final vein quick and easy, ensuring a watertight model.
Bientôt un traitement plus efficace contre le glaucome ?L’Inserm révèle que des chercheurs ont réussi à préserver la vue de rongeurs atteints de glaucome. Ils ont en effet réussi à bloquer les chimiokines qu’ils avaient identifiées comme étant à l’origine de la pression intraoculaire.Le glaucome est une pathologie fréquente pour laquelle environ 800.000 personnes sont traitées en France. Celle-ci entraîne une augmentation de la pression dans l’œil à cause d’une structure oculaire, le trabéculum, qui s’obstrue et n’évacue plus l’humeur aqueuse. Deuxième cause de cécité dans le monde, le glaucome touche cinquante à soixante millions de personnes dont 6 à 7 millions sont aveugles. D’où l’importance trouver des traitements.À lire aussiMaladie de Charcot : symptômes, causes, traitement, où en est on ?Or, les traitements actuels contre le glaucome ne ciblent pas directement l’atteinte du filtre, ce que les spécialistes appellent la “trabéculopathie”. C’est ce qui pourrait expliquer certains échecs thérapeutiques qui peuvent conduire parfois à la cécité en dépit de la prise en charge médicale. Toutefois, une lumière apparait aujourd’hui au bout du tunnel puisque des chercheurs viennent de faire une découverte pleine de promesses. En effet, une équipe de l’Institut de la santé et de la recherche médicale (Inserm) a pu observer une amélioration chez des rats atteints de glaucome. Ils ont constaté que le blocage de chimiokines, chargées de la communication entre cellules, permettait de diminuer la pression à l’intérieur de l’œil.Les molécules concernées connues sous le nom de CXCR3 ont non seulement maintenu la pression intraoculaire mais ont aussi empêché le fonctionnement normal du filtre oculaire (le trabéculum). Comme l’explique le chercheur et ophtalmologue Alexandre Denoyer, auteur principal de ces travaux à paraître dans la revue Plos ONE, il s’agit d’une “stratégie inédite” qui cible directement les chimiokines au niveau du trabéculum. Selon lui, ces résultats, “pourraient aboutir au développement d’un traitement innovant en remplacement ou en complément des traitements à long terme par les collyres actuels”. Il précise ainsi que “c’est la première fois qu’on arrive à s’attaquer à l’origine de la maladie”. Devant ces résultats prometteurs, des travaux seraient même déjà en cours. “Nous sommes en train de développer un collyre qui sera utilisable, j’espère, chez l’homme dans quelques années et qui va nous permettre d’améliorer la prise en charge des patients glaucomateux”, commente encore le chercheur cité par l’AFP.Le 5 juin 2012 à 14:07 • Maxime Lambert
A National Weather Service meteorologist says Clark County has an elevated chance for another thunderstorm today, but if a storm moves over the area, it should be weaker than Wednesday’s heavy downpour.“It’s about 20 to 30 percent right now. It’s a pretty good shot for one to happen, but there won’t be as much rain, hail or lightning as before,” said Colby Neuman, with the weather service in Portland.Clark Public Utilities spokeswoman Erica Erland said in an email that Wednesday’s thunderstorm caused significant weather-related outages — several in east Clark County.“At the peak of the storm, there were seven outages affecting about 6,800 customers. We had three dispatchers working to move six servicemen (the utility’s first responders) … and three crews around the county for restoration work,” Erland said.The utility workers were able to restore power to the majority of customers by about 9 p.m., and fewer than 1,000 remained without power for a few more hours as repairs were completed, Erland said.

Sachin and Kambli in the videoTwitterThe story of Sachin Tendulkar and Vinod Kambli’s friendship is legendary. However, in the last decade, their relationship went through some turmoil due to certain statements from Kambli. However, the two men seem to have put the past behind them. Their Twitter posts have been oozing with that same spirit of bonding which saw them put up a world record partnership in their school days.On Friendship Day, the Master Blaster posted a video on his Twitter timeline which shows the two old buddies engaged in a friendly cricket video game contest. This video is indeed special as it has the former Indian cricketers eschewing that spirit of friendliness which makes you realise that while they may have grown up, somewhere in their heart, they still have the same child-like enthusiasm.Happy #FriendshipDay guys… always remember that there are ‘No boundaries’ in friendship! ?@vinodkambli349 pic.twitter.com/qe6hT7Y7lx— Sachin Tendulkar (@sachin_rt) August 4, 2019 TwitterThe video ends in a special way also. After their game ends, the two men have a high-five. Then, Kambli says, let’s have a super over. Tendulkar responds by saying: “In this match, there are no super over.” When his friend asks why, he replies: “Because in friendship, there are ‘no boundaries.'” This is a cheeky remark aimed at the World Cup final and the boundary count rule that awarded England the trophy.Kasa visru shakto! Miss our playing days.?Why don’t you come over, we’ll do something fun.Guys, any suggestions?? https://t.co/TIoABbfdGM— Sachin Tendulkar (@sachin_rt) August 3, 2019 This followed a tweet posted by Kambli earlier in the day where he claimed to “have beaten the Master Blaster in his own game.” He then asks: “Who’s the Universe Boss?”Sachin replied by posting a video where he challenges Kambli to another match and says the first one wasn’t recorded while the next one will be.Kamblya, found this photo of ours from our school days.Memories came rushing back and thought of sharing this. pic.twitter.com/pUkOablTAX— Sachin Tendulkar (@sachin_rt) August 3, 2019 Even on the previous day, there were some heart-touching Twitter exchanges between the two men. Vinod mentioned a funny anecdote relating to their young days when Tendulkar decided to let his friend suffer a serious admonition from their late coach Ramakant Achrekar. Sachin also shared an old photo from their school days with a lovely caption. Hopefully, this spirit of friendship will continue without any hiccups in the future.

Credit: Sinfonia Technology/via TechOn Aside from autonomy, another key distinction is that Sinfonia’s robot can handle the fact that not all solar panels are alike; the robot is designed to tackle panels that tilt in different ways. To clean tilted solar panels on a mounting system, the robot can move on a planes tilted at 5-30°. If there is a gap between panels, the robot can go over a gap of 50cm or less and can deal with a height difference of 30cm or less.The robot is powered by a battery and is capable of wireless data transmission. A tablet can be used to check the robot’s status—to check if, for example, it has enough water or to check the battery charge remaining.Sinfonia Technology, in promoting the benefits of its panel-cleaning robots, also noted cost advantages over using manpower for cleaning panels.Generally, experts say that, for large-scale solar panel installations, attention to keeping the panels clean makes sense. Earlier this year, however, a study out of the Jacobs School of Engineering at University of California San Diego, in quantifying losses of electricity output due to dirty solar panels, found panels that hadn’t been cleaned, or rained on, for 145 days during a summer drought in California lost on average a little less than 0.05 percent of their overall efficiency per day. Cleaning the panels often was not worth the cost, found the study’s engineers. They cautioned, though, that their study focused on smaller systems and that, for very large installations, economies of scale may mean that washing panels was worth it.Sharp, meanwhile, is another Japan-based company showing interest in devising automatic ways to clean solar panels. Last month, IDG News Service reported that Sharp, manufacturers of solar panels and generation systems, placed on show at the Ceatec expo in Tokyo an automatic cleaner to latch on to the top of a bank of solar panels and clean them. According to the report, Sharp is working toward commercializing the cleaner, which will first work on the company’s own panels. © 2013 Phys.org Cleaning solar panels often not worth the cost, engineers find More information: www.sinfo-t.jp/eng/index_a.htmvia TechOn This document is subject to copyright.

(Phys.org) —At large-scale solar plants, keeping the surfaces of solar panels free from dust, sand and bird droppings is not just a matter of finicky housekeeping. It can be a matter of plant profitability. Dirty panels lower power generation efficiencies. Bird droppings on panels, for example, block the sunlight. A Tokyo-based company has a solution. Sinfonia Technology announced late last month that it has developed a robot with camera and sensors that can move autonomously and clean solar panels at large-scale solar power plants. Sinfonia’s robot has a distinction in being “autonomous” in that, rather than tethered to rails, the robot is able to move from panel to panel, to tackle the panels’ dirt and debris. The robot is equipped with scrub brush, wiper and detergent; and also sprinkles water stored in its tank. The robot can work in the dark; it has LEDs, having wavelengths in the infrared range.

Phys.org: Why is this planet so much hotter than Jupiter?Nielsen: The main reason this planet is so much hotter than Jupiter is that it’s so much younger, so it still has a lot of the heat it got when it first formed. Over hundreds of millions of years, it’ll radiate away that heat and cool down, and come to look more and more like Jupiter. So this planet represents a great opportunity to see what Jupiter probably looked like when our solar system was much younger, before the Earth had even finished forming.Phys.org: What was the role of Gemini Observatory’s Planet Imager in this discovery?Nielsen: Discovering 51 Eri b wouldn’t have been possible without GPI. The Gemini Planet Imager was designed from the start to do exactly what it’s doing now, detecting the faintest planets very close to their parent stars and characterizing their atmospheres. Previous instruments at large telescopes have looked at the star 51 Eri over the past decade, but the planet was invisible to them because it just got lost in the glare of the star. As part of the Gemini Planet Imager Exoplanet Survey (GPIES) we have an incredible opportunity to search for these previously-hidden planets and learn about them, and really place our own solar system into context.Phys.org: Is it actually possible that 51 Eridani b could host alien life?Nielsen: While we don’t have the capabilities to detect life or rule it out, based on what we know now, it’s very unlikely that 51 Eri b hosts life. As a gas giant like our own Jupiter, it has no surface or liquid ocean, both important to development of life on Earth. It might be possible for 51 Eri b to have rocky and icy moons, because all the giant planets in our own solar system have multiple moons, which might provide a location for life to develop. However, such hypothetical moons would be completely invisible to our current technology.There’s speculation that life could arise in the oceans of Jupiter’s moon Europa, beneath the 10 to 30 km icy surface, where the liquid water ocean is heated by tidal forces from Jupiter. Though confirming whether life really does or has lived on Europa will require a future probe that can somehow get beneath that surface of ice. Timescale is an important factor. It took about a billion years after Earth formed before life first appeared, and 51 Eri b orbits a star that only formed 20 million years ago, so if moons do form around 51 Eri b that are a good place for life to arise, it’s probably much too early for life to have appeared.Phys.org: What do we know about this planet’s atmosphere?Nielsen: The atmosphere is pretty interesting, and it’s a good deal cooler than extrasolar planet atmosphere we’ve taken spectra of to date. From the spectrum, we can tell that there’s methane and water in its atmosphere, which looks a lot like the inner parts of Jupiter’s atmosphere. Also like Jupiter, 51 Eri b probably has bands of clouds on its surface giving it a striped appearance. Phys.org: Do you plan further observations of the planet? If so, what kind of observations? What instruments do you plan to use?Nielsen: Right now, our sun is between the Earth and 51 Eri, so it’ll be another one to two months before we can observe this planet again. But once it’s visible again, we have lots of plans for future observations, many with GPI. We want to track the orbit of this planet over time, and see if it’s in a mostly circular orbit like the giant planets of our solar system, or if it’s in a very eccentric orbit like many of the closer-in giant planets astronomers have detected around other stars using the radial velocity technique. GPI also allows us to take spectra at shorter and longer wavelengths than our current data, so we can do a more complete comparison to other planets and theoretical models, and really understand what the atmosphere is made of and the bulk properties of the planet.

Phys.org: The discovery created a lot of buzz in various scientific media. Is it really such an important finding, a milestone in the search for exoplanets?Eric Nielsen: The reason we’re all so excited about this is that 51 Eri b is the first time we’ve discovered an extrasolar planet by direct imaging, where the planet looks so much like a giant planet in our own solar system. Other giant planets we have images of are interesting in their own right, but they look very different from what we’re used to. For example, HR 8799 is a massive star that hosts four giant planets between seven and 10 times the mass of Jupiter, between 15 AU and 68 AU. 2MASS 1207 is a brown dwarf with a four-Jupiter-mass planet at 46 AU.The other planets we’ve imaged around other stars tend to be at larger orbital distances and hotter, simply because those are easier to detect, but GPI’s (Gemini Planet Imager) incredible ability to detect faint companions close to their stars means we’re sensitive for the first time to these closer, cooler planets. We still don’t know how often planets like this form, and finding and studying 51 Eri b is an important clue to uncovering how planets form around other stars, and whether the formation of the giant planets in our own solar system was an unlikely fluke or a common process.Phys.org: Does 51 Eridani b resemble Jupiter?Nielsen: 51 Eri b just looks more like something we’re used to seeing in our own solar system, orbiting a star that’s a little more massive than ours, and only twice the mass of Jupiter and at a separation between the orbits of Saturn and Uranus.In addition, the spectrum of 51 Eri b shows that it has a lot of methane in its atmosphere, which is an important component of the atmosphere of our solar system’s giant planets. The other giant planets we’ve imaged around other stars either have very weak or no signs of methane in their spectra, so seeing something more similar to what we’re used to locally is pretty exciting. 51 Eri b is at intermediate temperature, too, at 800 degrees Fahrenheit, it sounds pretty hot by human standards, and certainly compared to Jupiter at -200 degrees Fahrenheit, but it’s significantly cooler than other extrasolar planets which are closer to 1200 degrees Fahrenheit. An artistic conception of the Jupiter-like exoplanet, 51 Eri b, seen in the near-infrared light that shows the hot layers deep in its atmosphere glowing through clouds. Because of its young age, this young cousin of our own Jupiter is still hot and carries information on the way it was formed 20 million years ago.

(Phys.org)—The discovery of 51 Eridani b, a Jupiter-like exoplanet, made headlines last week as it is the lowest-mass planet ever directly imaged around another star. Significantly, the planet resembles Jupiter in its infancy and shows the strongest methane signature ever detected on an alien planet. In an interview with Phys.org, astronomer Eric Nielsen of the SETI Institute, a member of the team that found 51 Eridani b, talks about the importance of the discovery and characterizes the newest addition to the list of known exoplanets.

Blazars, classified as members of a larger group of active galaxies that host active galactic nuclei (AGN), are the most numerous extragalactic gamma-ray sources. Their characteristic features are relativistic jets pointed almost exactly toward the Earth. In general, blazars are perceived by astronomers as high-energy engines serving as natural laboratories to study particle acceleration, relativistic plasma processes, magnetic field dynamics and black hole physics.Studies show that high-redshift blazars (with redshifts above 2.0) hosting massive black holes and the most powerful relativistic jets are the most luminous ones. Finding and observing new blazars at high redshifts could be crucial for providing insights into many phenomena of the universe, including the evolution and space density of massive black holes.A team of researchers led by Vaidehi S. Paliya of DESY research center in Zeuthen, Germany, investigated one such high-redshift blazar. They used the Large Area Telescope (LAT) on board NASA’s Fermi Gamma-ray Space Telescope and other instruments to characterize physical properties DA 193 – a blazar observed close to the galactic anti-center at a redshift of approximately 2.36. These observations resulted in the detection of significant gamma-ray emission from this object.”In this work, we present the results of our study on another high-redshift blazar DA 193 (also known as 0552+398; z = 2.363, Wills & Wills 1976; McIntosh et al. 1999) which we have found as a new gamma-ray emitting object through our detailed Fermi-LAT analysis,” the researchers wrote in the paper.DA 193 underwent a significant GeV flare in the first week of 2018. According to the study, it was an extremely luminous gamma-ray flare with a luminosity of about 130 quindecillion erg/s. The researchers note that such a GeV flare from a high-redshift blazar is a rare phenomenon. This is due to the fact that these blazars are generally faint in the gamma-ray band.Notably, DA 193 has an extremely hard gamma-ray spectrum. “What makes this event a rare one is the observation of an extremely hard γ-ray spectrum (photon index = 1.7 ± 0.2), which is somewhat unexpected since high-redshift blazars typically exhibit a steep falling spectrum at GeV energies,” the paper reads.Trying to determine what caused such an intense and luminous flare from DA 193, the astronomers suggest that a change in the behavior of the underlying electron population could be responsible for the observed event. The team intends to use LAT for further continuous monitoring of the gamma-ray sky in order to find more powerful blazars showcasing luminous flares like DA 193. Studying such events could lead to a better understanding of radiative processes powering relativistic jets in blazars.

Kolkata: Bongoan Municipality with the help of state Urban Development and Municipal Affairs department has taken up a water treatment project at an estimated cost of Rs 300 crore.One of the main objectives of the project is to supply arsenic-free water to the people living in the municipal area. People at various places in Bongaon have to depend on the ground water as a result of which they are often exposed to arsenic. Underground water in some parts of Bongaon are filled with arsenic that causes serious harm to humans. Also Read – Rain batters Kolkata, cripples normal lifeThe Bongaon municipality in financial assistance with the Urban Development and Municipal Affairs department has started construction of five water reservoirs under its jurisdiction. A water treatment plant will be installed in the area that will purify the water extracted from the river near Kalyani and the purified water would be stored in the five water reservoirs and supplied to the people at various wards. Once the project is completed, the people in the area will be able to have arsenic-free drinking water.

They also welcomed the move taken by the present municipal board with the help of the state government. The water will be transported to Bongaon’s Kalitala area where a water treatment plant is coming up. Underground pipe line will be laid along Chakdah-Bongaon road covering a distance of 51 km. It was learnt that the water treatment plant is being constructed on a 10-bigha land. Once the river water is treated, it will be supplied to the reservoirs. Sankar Adya, the chairman of the municipality said the project would be completed soon and they would be able to supply purified drinking water to every household. He also thanked Chief Minister Mamata Banerjee for her efforts without which the project would remain a distant dream. “We urged the Chief Minister for a water treatment plant in the area and she readily accepted our proposal. The project is being constructed on a war footing. A large number of people will be benefitted by the project initiated by the state government,” Adya said. Tarak Dey, a resident of Bongaon said: “The people in the area had demanded purified drinking water for a long time. We are thankful to the present government for making the project happen.”
