Short summary

Existing solutions for the problem of constant-flux pumping (CFP) in a two-zone confined aquifer involve laborious calculation. This study develops a new approximate solution for the problem. The solution is in terms of a simple series expanded by integers and thus very convenient for those who are not familiar with numerical methods. A quantitative criterion for the validity of neglecting the vertical flow component due to a partially penetrating well is provided.
