Hi All,

I need guidance on whether we need slotted piping/casing for our borewell or not? What are pros and cons for this?

The pump was stuck and was fished out through steel cable after cutting the water supply pipe. The scanning report says that there are loose bolders in the first 200ft of 1100ft borewell which can cause problem in future so as a solution, we have put slotted pipes till the bottom.

I have a ten acre plot in southwest of Bangalore with a borewell that yielded 2000gph till 2012, when it went dry. I dug a new borewell, after consulting a geologist,at a distance of 200', south of the existing one, last year. It yielded around 8000lit/hour till last week and now water comes in jerks and it seems it too may stop any any time. I have dug around 4 pig bits (20'X20'X10') at distances of about 100m from the borewells which catch rain water and retain them till Dec. only for the purpose of recharging the borewell ( assuming that I recharge my borewell).

Declining groundwater levels and increasing maintenance costs are the norm for most people these days, but residents of Rainbow Drive are exceptions.

"Just having the people of Delhi look at their water meters everyday will enable the city to deal with its current water supply", said K.P Singh.

He should know.

Singh is a resident of Rainbow Drive, a bungalow community in Bangalore. Led by him, the society has revolutionised its water availability from chronic scarcity to self-sufficiency.

Kaikondarahalli kere went from being a polluted, sewage-filled cess pool into a flourishing, clean lake home to birds, fish and the local community too!

Priya Ramasubban personifies the words ‘good things come in small packages’. This sprightly, self motivated enthusiast, saw a marshy, polluted cess pool, hemmed in by an open tract of land, where labourers and migrants daily dipped in for their morning ablutions. Talking to people around, she realised that this soggy piece of wetland was once a lake. Kaikondarahalli Lake was part of a manmade chain of lake systems, built hundreds of years ago.

What better way to see how to resolve this stinky situation than to put her foot right into this foul water!

Hi,
We are a residential complex in Bangalore, India

We have 2 overhead tanks in 2 adjacent buildings to which water is pumped through a common underground reservoir. Presently we have 2 separate pipelines for both the tanks running in parallel till 75% distance and then the 2nd pipeline extends onward.s
The pumps have been in use for 15 Years and so I presume they would not be very energy efficient.

Garbage dumping in lakes has upped nitrate levels and also caused a decline in groundwater quality. While urbanisation is the main cause, civic agencies failure and citizens apathy are also to blame.

"Growing garbage menace ups nitrate content in lakes", said a recent headline in the Deccan Herald that highlighted a study conducted by the Indian Institute of Science (IISc) on illegal dumping sites situated near water bodies in Bangalore.

We have a borewell 700 ft deep and get 3" water from it. In it is installed a 15 HP motor and and it supplies water to 100 houses. But now , after power is switched on , 3" water pumps for 5 minutes and then stops; and thereafter water comes in bursts.

We noticed that if we switch off the motor for 5 mins and then switch it on again, the 3" water pumps for 5 mins.

My question is if by switching off motor for 5 mins, we get a water storage for pumping 5 mins, then why does the intermittent supply occur?
