Summary:

This American Water Works Association (AWWA) standard outlines the requirements for polymeric lining of potable water pipelines with a diameter of 4 inches (100mm) and larger. It serves as a guideline for manufacturers, consumers, and the general public by providing a consensus on the specifications needed to ensure satisfactory service of the product. The standard details the materials, structural techniques, and procedures for applying polymeric linings, which act as a corrosion barrier within water pipes. It also covers quality assurance, verification methods, and the handling of special issues such as chlorine degradation. This document is intended for use by professionals in the water industry and is subject to periodic review to ensure it remains up-to-date with industry practices. Generated by AI.

Intro

Foreword

I. Introduction.

I.A. Background. Water pipe rehabilitation through application of polymer based in situ spray lining has been used to provide a relatively impervious barrier between the water transported in the pipe and the inside pipe wall to prevent its corrosion and t

I.B. History. The original pipe rehabilitation method of in situ spray lining used cement mortar, and this remains a standard practice in North America. Cement cure time is generally a minimum of 24 h before water can be introduced back into the main. Thu

I.C. Acceptance. In May 1985, the US Environmental Protection Agency (USEPA) entered into a cooperative agreement with a consortium led by NSF International (NSF) to develop voluntary third-party consensus standards and a certification program for direct

II. Special Issues.

II.A. Chlorine and Chloramine Degradation of Elastomers. The selection of materials is critical for water service and distribution piping in locations where there is a possibility that elastomers will be in contact with chlorine or chloramines. Documented

II.D. Purchaser's Role. It is important in the application of spray-in-place polymers that the purchaser or its field representative ensures the constructor's adherence to the quality assurance plan and highlights any variations or omissions which could c

II.C. Constructor Experience. The constructor shall have current training and certification from both the product supplier and the lining application equipment provider that the constructor is experienced in the successful application of the required spra

III. Use of This Standard. It is the responsibility of the user of an AWWA Standard to determine that the products described in that standard are suitable for use in the particular application being considered.
