scope:

This standard covers installation procedures for ductile-iron mains and their appurtenances for water service.

Conditions not discussed. Installations that require special attention, techniques, and materials are not discussed. Each of these installations requires special considerations based on many influencing factors that cannot be discussed adequately in a single standard. These installations can be performed by a competent engineering designer, including consultation with representatives of the material manufacturing industry. Some of these installations include the following:

1. Piping through rigid walls.

2. Piping on supports above or below ground.

3. Piping requiring insulation.

4. Treatment plant or pump-station piping.

5. Industrial piping.

6. Piping through geologically hazardous areas.

7. Piping in high-density-stray-current environments.

8. Piping through corrosive soil.

9. Piping through unstable soil.

Purpose

The purpose of this standard is to provide the minimum requirements for the installation of ductile-iron water mains and their appurtenances, including materials, dimensions, tolerances, and testing procedures.

Application

This standard can be referenced in specifications for installing ductile-iron water mains and their appurtenances. The stipulations of this standard apply when this document has been referenced and then only
