Borehole Yield

Top Previous Next


Borehole yield is the volume of water that can be abstracted from a borehole.


This is the maximum rate of abstraction from the borehole and can be expressed as l/s, m3/hr, m3/d or m3/a.

Why is borehole yield important?

It is important not to over pump the borehole in order not to induce saline intrusion, encrustation, excess lowering of the water table or piezometric surface or borehole failure.
