Corrugated Plastic Pipe Division Mission
To champion the advancement of corrugated polyolefin pipe in stormwater management, sewer and drainage applications by serving as the premier
educational and technical information resource.
Who is the CPPA?
The CPPA, a division of the Plastics Pipe Institute, is an international association of manufacturers, raw material suppliers, equipment distributors,
designers and manufacturers of equipment, and others involved in the production and application of corrugated polyethylene pipe used for the
conveyance of storm water, as well as in commercial, agricultural, residential, recreational and sanitation applications.
The Strong, Reliable, Cost-Effective Solution For Drainage
It is a fact: the next century of storm water technology and solutions is not written in concrete.
Over the past several years the specification and use of dual wall HDPE corrugated pipe for storm has increased dramatically based on factors
such as the pipe's strength, durability, joint integrity and long-term cost-effectiveness.
Results show that forward-thinking municipalities are realizing the future of the storm water
management relies on the best technology. HDPE corrugated pipe is manufactured from the highest quality
materials and is the most technologically advanced product available to move storm water and wastewater.
HDPE corrugated pipe is the proven, reliable, cost-effective and safe solution for your long-term drainage needs.
Strength - Chapter 4
HDPE corrugated pipe is a flexible pipe system that performs well in both high cover and low cover applications. Its unique ability
to support and distribute live and dead load enables it to meet almost every installation condition.
Joints - Chapter 3
Silt tight and water tight joints mean that what's inside the pipe stays inside the pipe, and what's outside stays outside.
This ensures that communities, citizens, ground water supplies and wildlife safer and more secure in their environment.
Chemical Inertness - Chapter 1
High-density polyethylene is one of the most chemically inert of all plastics and therefore is extremely chemical and corrosion resistant.
Abrasion resistance - Chapter 7
HDPE is very resistant to abrasion. These two characteristics give corrugated polyethylene pipe a significant long-term advantage over concrete and metal pipe.
Reliability and Security
Joints - Chapter 3
Silt tight and water tight joints mean that what's inside the pipe stays inside the pipe, and what's outside stays outside. This ensures
that communities, citizens, ground water supplies and wildlife safer and more secure in their environment. These integral joints meet the stringent standards
mandated by the EPA and comply with ASTM International and AASHTO specifications.
Tolerances - Chapter 8
Tight control of production and use of uniform, specified raw materials ensures that HDPE pipe is manufactured to the tightest tolerances.
Silt tight and water tight joints continue to perform under moderate deflections.
Durability - Chapter 7
HDPE pipe is well-proven in some of the toughest environments. More than 90 percent of the nation's natural gas supply lines are made of polyethylene
pipe, proving on a daily basis the reliability of HDPE pipe.
Quality - Chapter 8
CPPA and the Plastics Pipe Institute have in initiated a tough third-party certification program for manufacturers of corrugated HDPE pipe and resin.
The certification program tests for the material, dimensional, and physical performance properties as specified in AASHTO M294/MP7.
Installation - Chapter 6
HDPE pipe is light, tough and is manufactured in long lengths. This adds up to significant potential for installation cost savings.
Life Cycle Cost - Chapter 7
Because of HDPE's resistance to abrasion and to chemicals, polyethylene's pipe's life-cycle savings over alternative drainage systems are significant.
Users can expect a minimum service life of 100 years in many typical drainage applications.
