Hi,

I live in HBR layout. Recently, I found red and white worms coming out from all water taps in my place. Following this, I cleaned my overhead water tank and also the sump below. Still I could see the worms coming from it. Both the tanks are clean and couldn’t find any worms in it. Plumber visited and advised that they were coming from the inside pipes. He cleaned the pipes but I still found worms in all the taps. Could you please help me to find a solution to get rid of the worms?

Thanks

Hello,

Every time it rains, I see huge rain water gushing through the roads and drains of Bangalore city. The entire water gets wasted as it reaches the sewage and flows out of city as sewage water. If we can stock this running water across the areas, it should recharge the depleting ground water and increase the availability of water in private bore wells which shall decrease the load on the troubled water supply board.

Hello,

I have two bore wells on my premises. One of which is being used regularly. Another one is unused as the first one is giving sufficient water for current usage, Recently I was advised (maybe wrongly) that if I do not use water from the bore well, the underlying water will flow to neighborhood bore wells, which are continuously used. This will lead to long term shortage of water in my unused bore well. So I should keep using the second bore well as well. Is this logical and correct advise? Please help in understanding.

Thanks

Hi,

We have an query regarding compression pump / submersible pump for domestic use in our native place. We have shallow installed which is currently working via Hand pump. The shallow / bore well is 600 feet deep, with 70 - 80ft 4in pipe and remaining 520-530 ft in 2in pipe. During summer water levels go below 70 ft. This makes the handpump very difficult to operate.

Dear All,

I have a property in Madipakkam, Chennai. I drilled borewell in the year 2000 in my property at about 200 ft. From that time till now, I am getting only one bucket of water, approximately equivalent to 50 litres per day till now.

I feel that this is very low and so am thinking of reinspecting the bore. I would like to know if borewell endoscopy using a camera will give me a clear picture of what the problem is.  Could anyone please be able to recommen a good vendor for borewell endoscopy with a camera at Chennai?

Regards
