Over the two decades I’ve been involved with Contech A-2000™ PVC Pipe, there are a handful of concerns I am asked about once-a-year, it seems.  One of them is in regard to field tapping the profile wall, or corrugated, A-2000 sewer pipe.  Some engineers are worried that the tap can’t be water tight..A few thoughts to consider…  A-2000 has been

Hello all… how about a quick blog on PVC pipe and UV protection? I am often asked about the effects of UV exposure caused by sunlight on PVC sewer pipes and how to provide protection. Many people in the civil engineering industry have concerns with UV exposure and polymeric-based sewer materials (e.g. thermoplastic, PVC, HDPE, other plastic pipe)

 I’ve recently been seeing engineers choosing what I feel are inappropriate Manning’s “n” coefficients for sewer design.  Some choose too conservative values, while others don’t understand that long term creep within the pipe wall may adversely affect the hydraulic performance of certain pipe types.  A few things to consider are as follows:
