Q2. Question regarding well foundation. what is the rate of sinking well in your site
Ans. 
The rate of sinking wells varies based on soil conditions, equipment, and project specifications.
• Typical sinking rates range from 0.5 to 2 meters per day, depending on soil type.

• In soft clay, wells may sink faster due to lower resistance.

• Using advanced drilling techniques can increase efficiency and speed.

• For example, a well in sandy soil may require slower sinking rates to ensure stability.
