Is CPVC or HDPE pipe suitable for borewell of 215 feet with submersible pump

We have HDPE pipe in our borewell which has started leaking. The borewell is around 215 feet deep and we have kept the motor at 180 feet. Since the pipe is around 5+ years old and is the second time leakage is occuring, I am planning to replace the pipe entirely.

What is the recommended pipe (CPVC or HDPE) for this installation from a cost and reliability perspective. And also what would be the cost per feet for both of the above in Bangalore. Please advice.
