INTRODUCTION

With the adoption of HDPE as a potable water distribution system material it has become increasingly important that owners of these systems ensure that the benefits associated with this material are not compromised by non-standard installation techniques. With the advent of HDPE 4710 materials, which are resistant to stress cracking, the leading cause of failure is installation error followed by third party damage. The purpose of this document is to standardize the inspection of piping installations. The HDPE Municipal Advisory Board (MAB) members identified the issue of achieving consistent inspection and created a task force to develop this document. The MAB membership consists of municipal water companies/cities staff, college researchers, contractors and designers all involved in furthering the proper adoption of HDPE potable water systems.
