HDPE Directional Drill Transition

HDPE Directional Drill Transition

HDPE Directional Drill Transition

(OP)
I'm designing a replacement junction box outside of an existing pump station which sits next to a creek. There are two existing HDPE HDD lines (10" & 18" HDPE) crossing the creek which are connected to DIP which is anchored in a large concrete block. The client wants to eliminate all of the DIP and connect PVC directly to the HDPE pipes.

I've never heard of doing this, but wonder if there will be any problems, especially since the HDPE has been in the ground around 20 years.

Thanks,

Mike

RE: HDPE Directional Drill Transition

Not really enough info. This on the pressure side? What size PVC? Is there a flange on HDPE?
