Depleted Earth Site?

Electricity substation, Wood End Road, Harrow

What does "Depleted Earth Site" mean? Google doesn't seem to know exactly. This is outside a local electricity substation.

Update: It appears to be just a fancy way of saying that if you step through this gate you will fall into a hole. There’s a deep hollow behind the fence.
