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.

Toxic industrial waste has polluted groundwater in Ratlam. Residents wait for action from authorities.

A resident of Bajankheda village in Ratlam district of Madhya Pradesh, Sitabai Tindor shows her pot full of water to us. A strange red, the water looks unusual. “We have been using this red water for domestic use for the last two decades. Industries in Ratlam has spoilt our land and water. The government has not provided us with any alternatives. For industrial misdeeds, why should we suffer?” asks a visibly distraught Sitabai.

Studies reveal that efforts at guinea worm eradication have triggered the spread of hydrofluorosis in Rajasthan.

Up until two decades ago, the main sources of drinking water in Rajasthan included surface water from perennial ponds, reservoirs, lakes, dams, rivers and streams with borewells and tubewells used sparingly and only in remote areas. All this changed when guinea worm infections started appearing in the state.
