What is best, single or two pumps for two borewells?

For two borewells, should I use single or two pumps ?

Dear Sir,

This is S.Subramanian. I have two borewells in my home (70 feet and 200 feet). I recently dug the 200 feet borewell whereas the 70 feet was dug ~ 20 years ago. Can I use a single compressor pump to alternatively draw water from two borewells. I use 0.5HP jet pump as of now in the 70 feet borewell. The water level is dropping and hence I switch on every 5 hrs for 10 mins.

Thank you.
Yours Sincerely,
