HDPE Pipe
Enquiry
The 6-digit pipe material codes in the Q-Sheets appear to identify the HDPE pipe sewer requirements for gravity storm sewers with a closed profile HDPE. Typical HDPE storm sewers are ‘open profile’ pipe with a corrugated outer wall and bell & spigot connections, such as N-12 Dual Wall by ADS or Boss 2000 by Armtec. ‘Closed profile’ HDPE pipe with its smooth outer wall and welded or threaded connections is typically used for relining existing pipes and is a much more expensive product. Typically the majority of MTO tenders specify open profile HDPE. Please clarify through revised Q-Sheets for the “Pipe Sewer” items (items 41 through 48) that open profile HDPE sewer pipe is permitted instead of closed profile HDPE.
