Water tank is taking longer time than usual to get filled with borewell water

We have 235 feet borewell at home and we use texmo compression motor to pump. We observed that the water is not pumped up to the water tank from past few days. We could see meagre water in tank even if motor is running for more than an hour. We already had a borewell with 90ft depth and since there was no water, we installed new one last year with a depth of 235ft after checking with experts. We did not face any issues till date and the electrician has checked the motor and confirmed no issues with it. My query is, if the motor is running fine then the possible reason for water not getting pumped into the the tank is that the groundwater level must have gone down or any other problem? Please provide your suggestions.

Note: We live in Kundrathur, Chennai, Tamil nadu.
