To Pipe A Waterway: Fill & Download for Free

(image source-google search)First of all thanks for the A2A, @Akshay PankhadeDefinitely biotoilets introduced in Indian Railway coaches is a good idea, as it keeps the tracks clean and are eco friendly.The traditional toilets used in Indian Railways are Hopper Type. They are having a Commode Chute(a long outlet pipe), which opens up directly on the rail tracks. The issue with this is that, they are having serious health issues and more problems arise when the train passes over a waterway or an over bridge or when the train is stopped in the station.As a solution biotoilets developed by DRDO(Defense Research and Development Organisation) where introduced and the only end products of the new system is methane and water. It works on aneorobic bacteria that are present in the tank which feed on human excreta. All you have to do is replenish the supply of bacteria once or twice in an year.S o it is definitely a good idea, and by 2022, India will see biotoilets on all its coaches.Swach Rail, Swach Bharath!

A culvert is a structure that can allows water to flow under a road, railroad, trail, or similar obstruction from one side to the other side. Typically embedded so as to be surrounded by soil, a culvert may be made from a pipe, reinforced concrete or other material.A bridge a structure carrying a pathway, roadway, or railway over a waterway.If the span is less than 6.5m (or 20ft ), it is called a culvertAnd it is a bridge when the span is more than the specified length.A culvert usually is either circular or rectangular in cross section , so it has an all-enveloping structure (i.e a roof, 2 walls and a floor).Bridge sits on foundation on each bank( or on wing-walls) and as it does not have a floor , it is called a bridge.BRIDGES:Padma Bridge in Bangladesh11th longest Bridge in the world -jamuna Bridge BangladeshCULVERTS:

The main reason is lack of water, though with massive investment we could pipe water inland over huge distances, but we don’t have the capital.Actually, most people don’t realise that lots of people live inland on pastoral or mining leases. Very isolated and hard life, and you have to truck everything in.There is a $55billion proposal to build a 3000k railway between the WA iron ore mines & the QLD coal mines, with smelters on each end. That could open the centre for us, but there is still the water problem.Iron Boomerang - Wikipediahttp://www.eastwestlineparks.com.au/It was easier for the USA to settle there interior simply because they have a vast network of inland rivers, many navigatable (eg: the Mississippi).Inland waterways of the United States - WikipediaAustralia because of the vast distances involved and high inland evaporation rates would have to pipe the water inland. Its been looked at different times as new technologies have become available but the sheer cost make the idea unworkable.
