One way to easily and repeatedly catch rain water run off is to dig staggered contour trenches wherever possible. In forests, in grasslands, on marginal lands both government and private.

Our effluent contains a TDS of 3000 ppm while after equalisation - that is after addition of lime and alum - our TDS increases to 4500 ppm giving our outlet TDS to be 5000 ppm. In this project we haven't installed any tertiary process. It consists of simple equa...

  • I dug a bore well of 270 feet depth. Only 45 feet is filled with pipe. No inner is erected after 45 feet. They told me no need of it because the rock is strong. Water spots are found at 93 feet and 125 feet. So they digged to 270 feet for maximizing the occupying capacity of the well. They told me t...

A partnership between Biome, ACWADAM and WIPRO brought stakeholders together to map Sarjapur's aquifer.

The problem of Bengaluru’s water is well known. The demand for water tankers skyrockets during the summer months, when municipal and borewell water supplies run dry, and many of the city’s lakes, actually man-made tanks, lie neglected and polluted.

Last night there were heavy rains in my area and suddenly storm water surged in and filled up my sump tank and borewell with contaminated storm and sewage water. What is the immediate action I need to take to be able to use the borewell water (not for drinking)? Do I need to put some powder to make it safer for use?

Most ground nearly everywhere is sloping in various degrees. Much more so in the hills. One way to easily and repeatedly catch rain water run off is to dig staggered contour trenches wherever possible. In forests, in grasslands, on marginal lands both government and private. The forest departments could do this in a big way instead of mindlessly growing plantations after plantations which in most cases fail anyway. This strategy will also help so much of the root stock in the soil to come up, we would need very little plantation after that. Grasses would come up in a big way too.

Prior before drilling we have consulted Geologist of Ground water department as per his advise we have to go up to 200 feet. Till 50 feet we didn't had any issues, At 80 feet the bore vendor said the side rocks are soft rocks which are breaking into pebbles which is not advisable to drill further, if you drill further the bore rod may struck and we may not able to remove it, and so he stopped. Could you please suggest how should we proceed further ? Is there any way to overcome this.

I have a small doubt - can the rejected water obtained from a RO plant be subjected again to reverse osmosis? Is it cost efficient? Or can it be treated by bio- remediation? Please give me a possible way of retreating this water and please don't tell me to use in gardens, in toilets, etc.

Hi i am working for a project in ETP. Our effluent contains a TDS of 3000 ppm while after equalisation - that is after addition of lime and alum - our TDS increases to 4500 ppm giving our outlet TDS to be 5000 ppm. In this project we haven't installed any tertiary process. It consists of simple equalisation tank, primary clarifier, surface aeration , secondary clarifier followed by sand filter and carbon filter. after addiiton of lime our ph is 11.5 and after addition of alum we maintain a ph of 10.5. Please suggest me some solution for this problem.

I am from Coorg district in Karnataka and I suppose you know this is a hilly area. We have a existing borewell which is 250 feet deep and we get 1.5 inch water throughout the year, but this is not sufficient for agriculture purpose as monsoon was bad 3 years in a row. A Hydrologist gave a new point 8 feet from the existing bore well.He located this point by electrical conductivity. The reading that he got in his device was 130 to 140. He said its in a different rock and told that the old bore wont get affected.

Who selects the villages for water supply by tankers? How are they selected? How is the number of tankers for a particular village is decided? What is the water storage capacity of the tanker? At what cost each tanker is available? Who bears the cost? Where can I get tehsil wise data about number of tankers each year?

Mosquitoes spreading dengue are formed in water storage units. If rain water is stored in sumps there may be a chance for breeding of dengue mosquitoes. Dengue is a very dangerous virus resulting in death. Here in our area (Hosur, Krishnagiri District, Tamil Nadu) dengue is spreading fast. In our house I have made arrangements to collect the rainwater in sumps. But I afraid will there be any dengue mosquitoes here - please advise.
