What will it take for the Haryana government to switch 7 lakh groundwater pumps to solar powered options so it can lower its energy footprint and contain losses in the energy sector?

Haryana's agriculture sector uses seven lakh tubewells, most of which are connected to the grid as the state has a policy of providing highly subsidised electricity to farmers costing Rs. 6200 crore a year. As a result, groundwater exploitation is rampant. Per data by the Groundwater Department, most districts here have witnessed a critical fall in their groundwater table of 7.29 meters, on average, between 2000 and 2012.

The city's old wells and baodis are running dry, and the Yamuna is getting more polluted by the day. Where is Delhi's water going to come from when groundwater levels are also dropping?

Delhi, home to 16.75 million people, is in the grip of a major water crisis. Statistics by the Delhi Jal Board for the year 2011 suggest that the water deficit stands at about 250 million gallons per day with the supply being 830 million gallons per day. Unaccounted for water--the gap between the water produced and distributed--is as high as 40-45%.

Hi

I have a 6 inch borewell, with discharge of 1.5-2 inches water.  Water was first struck at 150 feet and the borewell is dug to a dept of 800 feet.

What is the ideal HP of the motor to be installed and at what depth must this be done for optimum utilization and less power consumption for agriculture purpose. 

Regards

Dear Experts,

I have a borewell in my house at KR Puram, Bangalore. The depth is about 580 feet. Rock was hit at around 107ft and the casing is done upto 110 feet. The submersible pump is fixed at 440ft which is of 4 h.p. I have encountered some loose gaps and boulders @ 320 and 420 ft respectively, and I have inserted slotted pipes for the entire well to get rid of the possible issues with loose gap and boulders. I have used the borewell for my house construction without any problem for almost an year. Now from the past few days, water from borewell is muddy.

Hi,

I had drilled a borewell for 400 feet in June'15. There was an existing borewell at the same place for 80 feet, but that was not yielding enought water during summer, hence i drilled it further to 400 feet. However it is still not yielding the desired result. The water coming out of the borewell is very less.I had used 2hp compressor motor and it has to lift the water to the 3rd floor where i have an overhead tank.

Hi,

We have water available at 250 to 300 ft in our land, but we have only 150v.

What is the best pump set, for this combination?

Thanks

Ashok

The proposed training is intend to develop capacity of the institutions / organizations / individuals through knowledge sharing on the application of solar energy for pumping and water treatment system appropriate for drinking water sector i.e. rural & urban water supply in India.

The Mahanadi's longest tributary, the Shivnath, has borne the brunt of urbanisation and industrialisation but the impact has been felt the most by residents. We capture their story in pictures.

The Shivnath River is the longest tributary of the Mahanadi River. It was the first river in India whose water rights (23.5 km stretch of the Shivnath River in Durg district, Chattisgarh) were sold to a private company Radius Water Limited (RWL) 16 years ago.

The concepts of System of Rice Intensification help farmers adopt practices based on their local conditions. Farmers, and an SRI expert in Chhattisgarh, show how it has worked for them.

Muneswar and more than 170 farmers in Ambikapur, Chhattisgarh have no regrets after shifting over from traditional agricultural methods of farming to the System of Rice Intensification (SRI) method. Why would they? Most of them have been overwhelmed by the kind of returns they have got compared to their investments.

"The crop yield has increased to more than two and half times, and we are getting better returns," says Kisan Naihar Sai, an SRI beneficiary.

What is System of Rice Intensification (SRI)?
