Rain water drainage system - Doubts on effectiveness

So they have recently dug up our street in Kodambakkam for laying this suspiciously thin pipe for rain water drainage system. I always thought water will corrode these rubber/plastic pipes easily and that’s why we use cement pipes as water pipes. Can someone with the right experience/ expertise tell if these kinds of pipes will actually help in water drainage in the long run or is it just another cash funnelling tactic?
