Ductile iron pipe (DIP) was introduced about 50 years ago as a
more economical and better-performing product for water
transmission and distribution. As with iron or steel pipes, DIP
is subject to corrosion, the rate of which depends on the
environment in which the pipe is placed. Corrosion mitigation
protocols are employed to slow the corrosion process to an
acceptable rate for the application. When to use corrosion
mitigation systems, and which system, depends on the corrosivity
of the soils in which the pipeline is buried. The Bureau of
Reclamation's specification for DIP in highly corrosive soil has
been contested by some as an overly stringent requirement,
necessitating the pipe to be modified from its as-manufactured
state and thereby adding unnecessary cost to a pipeline system.
This book evaluates the specifications in question and presents
findings and recommendations. Specifically, the authoring
committee answers the following questions: - Does polyethylene
