NASSCO Announces Two New
Grouting Specifi cations
After years of work from its Infi ltration Control
Grouting Committee (ICGC), NASSCO has published
two new grouting specifi cations: Pipeline
Packer Injection Capital Grouting and Pipeline
Packer Injection Pre-Rehabilitation Grouting V2.10.
First published in 2014, the Suggested Standard
Specifi cations for Pressure Testing and Grouting
of Sewer Joint, Laterals and Lateral Connections
quickly became the choice grouting document for
engineers and municipalities.
Updated for 2021, that document has been
enhanced and renamed " Pipeline Packer Injection
Pre-Rehabilitation Grouting. " Available for contractors,
engineers, and system owners to download
for free on the NASSCO website, Pipeline Packer
Injection Pre-Rehabilitation Grouting addresses
the need to eliminate infi ltration prior to installing
other rehabilitation methods and the ability of
chemical grouting to act as a complementary
technology after installed.
The second specifi cation, Pipeline Packer Injection
Capital Grouting, was developed by NASSCO's
Infi ltration Control Grouting Committee (ICGC) to
address long term grouting means and methods
that provide pipe stabilization by creating a pipe cradle-like
stability in the bedding and a volumetrically
signifi cant, long-term, water seal outside the pipe.
Specifi cations are available on the NASSCO
website.
New Pipes Could Ease
Some Water Woes
in Mississippi Capital
Mississippi's capital city will soon start installing
larger water pipes to replace some of the lines
that failed during a deep freeze that struck
the Deep South in February.
WLBT-TV reported that 48-inch
(122-centimeter) cast iron water transmission
lines have been arriving in south Jackson.
City engineer Charles Williams said offi cials
gave the order to proceed with the fi nal phase
of the project, which involves laying 2 miles
(3.2 kilometers) of pipes in the area.
The work will connect water transmission lines
from the O.B. Curtis Treatment Plant to south
Jackson. They will replace 24-inch (61-centimeter)
pipes that failed to provide adequate water
pressure from the plant during the winter storm. *
