Oh, there is some thousands of years of historical perspective behind that.
Historically lower castes in India were supposed to be the people responsible for cleaning, janitorial work etc. That's more like putting it mildly, they were sort of forced generations after generations to do absolutely despicable stuff like scavenging human waste. Cleaning streets, gutters etc. What's more you are forbidden to marry outside your caste, and there was a another social disease called untouchability- which was basically you can't share the same space with the lower castes. Like religious places etc. There are some extreme instances where people weren't even allowed to walk on the same roads.
They were barred from education, or any other work of dignity.
In short the worst kind of jobs were left for the lower caste. And people expect the same to continue, now as well!
The article also mentions how a common employment of women of the lowest caste is carrying leaky buckets of feces away from the toilet area, often on their heads.
