I am from central Chennai and groundwater level in our area has drastically reduced, wo have to depend on other sources (Lorry and Metro water). Metro water often gets polluted so we are looking for control valve open/close by observing the flow through hand pump before letting it to the sump. The challenge here is metro water line to the sump is some 8 feet deep and we don't have proper provision to get down. Can someone please advice if we can have some control valve above the ground level by any means ?

In Kerala, there was a devastating flood in the month of August. For a week or so it rained incessantly in the Western Ghats and on the plains. All the rivers were in spate. There were too many landslides on the hilly regions and the plains were under water for a week or so. When the flood waters finally receded and the region gained normalcy, a strange phenomenon was observed. The riverbed in many places have become sand dunes and the wells have become dry or the water table went down.

A 7.5 hp motor supplies to 06 number of G+3 building overhead tanks. At times, when few (say 04) buildings overhead tank are full, the pipeline system and motor gets pressurized due to supply to only 02 buildings. The pipe line is 2.5 inch dia. I have heard, variable speed motor may be helpful. Also, if someone can suggest auto shut/open system for such arrangement where there is supply from one motor is to 06 buildings.

Hello all,

We have 2 existing borewells as point marked by water dividers. We are not getting water from borewells. One of borewell has been dug upto the depth of 350 ft. We are getting very less water if we run motor once in a week. Please suggest either to go deeper on this or find new water points.

Location: 5 kms from Oragadam Sipoct towards Kanchipuram

Thanks in advance
