Soil Corrosivity to ductile iron pipe
Soil Corrosivity to ductile iron pipe
(OP)
We normally just use the AWWA 10 point scale for soil samples collected from test borings to help provide some guidance on polywrap requirements. However, pipes are always bedded and shaded with select material. Therefore, is it appropriate to test the native soils in the trench to determine corrosivity potential, or could we just be testing the bedding and shade material?

Perhaps you can get buy with slightly worse soils with select fill than you could if you went direct burial.
But when it comes to very wet and highly organic sites wrapping will still be needed.
