What if I told you this pipe dates back to ancient Bhārata of 2500 BC? Would you believe me? You need not believe me. This is what professional experts of Indus Valley Civilization and BMAC say.
The Indus valley civilization (c.2500 BC) had a complex drainage system connecting every private house of the city. So did the BMAC complex in the third millennium BC (Bactria-Margiana Archaeological Complex or the Greater Bactria region in the Northwest of ancient Indian subcontinent known in Sanskrit literature as Bāhlika. According to ancient Indian epic Mahābhārata the king of Bāhlika was a brother of Kuru King Shantanu of Bharata dynasty who was the great grandfather of Pandavas and Kauravas)
The city of Lothal had a very complex drainage system which collected waste from every private house of the city to dump it to a central sump outside of the city. Gonur in the northwest had these pipes for supplying water.
