how do you compute hydraulic pressure under foundation

[Petersr]

I need to determine the sump pump capacity required under a building basement. What are the required inputs and what formular or formulars do you use to determine the potential water to be removed by sump pumps for various depth of basements from 4 feet to about 10 feet.

Pumping requirements are site specific.

Perform well tests to establish drawdown effects of pumping. Consult a hydraulic text book for details.

Ensure to incorporate redundancy into the groundwater management system.
