Water conflict in Rajasthan’s Alwar district is not just between upstream and downstream users; it is also between users with domestic, agricultural and industrial needs.

Lewari, a village located around 17 km from Alwar in Rajasthan, is the site of a water conflict these days. “The production of Jayanti jaljeera, haazme ka lalantop drink (a digestive drink) has left our village parched,” says Nanak Singh, a resident. Singh is referring to the excessive quantity of water being used for manufacturing a digestive drink by a factory located in his village. The indiscriminate use of a lake bed in the village for industrial use has led to groundwater scarcity during peak summer months.

While Swachh Bharat Mission is focused on improving sanitation in the country, an ODF India remains a distant dream. Can corporate contribution ease the sanitation challenges India faces?

Despite making sanitation a national priority with Swachh Bharat Mission, 50 percent of India defecated in the open till 2014. The goal to make India open defecation free by 2019 seemed ambitious. The government provided funding but it also sought active participation from the corporate sector. Companies were compelled to loosen their purse strings as Section 135 of the Companies Act, 2013 made corporate social responsibility (CSR) mandatory.

Swachh Bharat Mission: Could the most ambitious cleanliness campaign in Indian history also be the most expensive failure?

India’s sanitation crisis involves huge cost. Transforming the country’s sanitation and waste management by 2019 is tall order. “Swachh Bharat Mission, the most ambitious cleanliness campaign in Indian history could well be the most expensive failure in recent times,” says Naina Lal Kidwai, CEO of FICCI and the Chair of India Sanitation Coalition, a platform for partnerships to work towards achieving sustainable sanitation for India.

Citizen Matters looks at what the city should do to manage its water better.

A recent BBC report projected that Bengaluru will run out of water soon.

Yes, it was a superficial list of cities that already have water problem. It just pronounced the harsh verdict without any in-depth analysis of the factors involved. That’s like taking a casual look at an emaciated man and saying, “he is going to die soon”.

Hi,

We are a pharmaceutical based company. We have an ETP which is designed for 30 KLD. In the aeration tank, we have observed slimy nature of the effluent when the sample is drawn. If we stir the effluent from the aeration tank in a 1 L beaker, we observe that the contents are slightly thick. The effluent in the aeration tank is light brown in color. We have never observed this in the past. Would like to know what can cause this.

Thanks

One of the many polluted Bengaluru lakes, Gottigere lake is being revived, thanks to the intervention of some responsible citizens.

Gottigere lake used to be a major source of water for south Bangalore. Its overflow fed several other lakes in the area. It was also the reason why so many people bought apartments nearby.

Dear Sir/Madam,

Our factory is located on a land from where the ocean is only about 3 kms. No municipality facilities are available for drainage of sewage water.

1.We have built a concrete septic tank through which we treat all sewage and collect the treated water, which is then carried to nearby village, about 15kms, and flushed into municipality gutters. Is this legal?

2. Can I recharge this water into bore well? Bore well in this area are not being used as the water here is very salty and not of any use.
