The Decaying Sewage Infrastructure of Calcutta, India

Calcutta-India-sewer-cleanerKolkatan sewers were once the envy of the world, built during the Victorian era and spanning 90 kilometers below the city. Because the Kolkatan sewer system is now 130 years old, it no longer functions as it should, especially when accounting for the increasingly large modern day population of Calcutta, India. Due to this, teams of workers with buckets enter the sewers every night all over Calcutta to shovel and remove excrement so that blockages don’t occur. Workers typically work 11:00 PM – 5:00 AM because this is when the least amount of people are awake to use the bathroom.
