Pipeline Chlorination Simplified
The previous chapters describe the procedures for pipeline
and storage facility chlorination (and dechlorination) that apply
to a multitude of situations. This information should be used to
correctly and effectively disinfect these water system compo-
nents. There is an overwhelming array of procedures needed to
effectively deal with every possible field situation. Even though
all of this information is needed to correctly disinfect pipelines
and storage facilities, of all possible sizes and with all the avail-
able chemicals under a variety of conditions, there are only a few
situations that represent the vast majority of conditions faced by
most system operators.
This chapter presents the most common pipeline disinfection
procedures needed to address the majority of field conditions.
Using these procedures greatly reduces the complexity of disin-
fection choices and, thus, simplifies field disinfection for most
pipelines. Although the procedures listed here represent common
practice of most utilities, there are many cases where other
choices are appropriate or even required. The information pre-
sented throughout this field guide provides the system operator
all that is needed to effectively disinfect (and dechlorinate) all
types of pipelines and storage facilities.
All of the following steps (from Chapter 3) need to be followed
to ensure a safe and efficient pipeline installation. The proce-
dures provided in this chapter are to simplify step #6.
1. Inspection
2. Sanitary construction methods
3. Flushing or cleaning
4. Preventing backflow during installation
5. Providing temporary service
6. Chlorination (chemical disinfection)
