It has been close to 3 years since I have been using a Grundfos 2HP pump which is 550 ft below the ground in my home bore well. It was all fine, till it stopped working a few days back. No electric or water level issues have been found. On taking the pump out we were shocked to see silt and boulder granules that have made their way into the mesh and damaged the pump. The motor appears to be ok.

Hi,

I lives in a 3BHK in Bangalore on 3rd Floor(top floor) and we have an overhead tank for supply, and we have added a Kranti Water meter now.
the problem is that the pressure is very low and when water taps are opened simultaneously in other bathrom, it becomes too low. I have researched on the internet & learned that there are pressure pump available to boost water supply.

Dear IWP

I have a set jet pump in Mark II tube well, and I want to use jet pump as well as mark II tube well also.

I do not want to remove head of the Mark II tube well. Is it possible to set jet pump in Mark II tube well without removing the head of the Mark II tube well?

Thanks

Dear Experts,

We are an apartment of 20 flats in 5 floors. Of late we observed that the pump takes ages (more than 7-8 hours) to fill the tank and is consuming more than 40 units per day. The height for pumping water (sump floor to overhead tank top) is around 85 feet and the tank capacity is 10,000 Liters. The existing pump is 1 hp (Single phase) with a discharge pipe of 1inch dia. What could be the root cause for such dismal performance of the pump?

An e-commerce platform selling water pumps has big plans for India but will they be able to buck the trend of incurring heavy losses that other online stores face?

The increasing gap in water availability in India has encouraged the growth of the water industry. Be it the bottling sector, filtration or wastewater recycling, all segments related to water are seeing a phenomenal upsurge. The sector is expected to receive investments of Rs 18,000 crore in the next three years according to a study conducted by the consultancy firm EA Water. No wonder then that e-commerce platforms are also vying for their share of the pie!

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.
