Thank you so much

Thanks for watching and appreciating. I will try to make video on SEPARATE & COMBINED SEWERAGE A SYSTEM . It in my future plan itself. As far as the Sewerage system of KOLKATA is concerned. The topography & rainfall patten is the major factor. As I could explore from internet itself I came to know that Kolkata is between Hooghly river on the west and Salt Lake to the east and slope of the the ground of the city area is west to east in general. The unique physical feature of Kolkata city is bowl shaped, the centre of the city is somewhat in lower elevation and as such every drop of waste water / storm water requires pumping to relieve water-logging. A greater part of the core city of Kolkata is served by underground drainage system of the combined type in which both sewage and storm water flows through the same conduit. The slope of the ground of the city area is west to east in general. The sewers are also sloped in that direction. The area is very flat and low like the shape of saucer with scattered and localized pockets. The drainage water is lifted and discharged ultimately into the tidal river further down to the east through outfall channels. The city sewer system has no separate dry weather and storm weather arrangement, as a result, almost all the major and minor underground trunk sewer lines are badly silted up for absence of cleaning at regular interval and this has made the reduction in flowing capacity of storm weather flow to a considerable extent. Hence if they provide the separate system for storm water and dry weather flow then it would be better as per my knowledge. I have taken this link as reference to answer your question. It is just the gist of this information I hope the answer is satisfactory.
