This paper presents the City of Edmonton's approach
for the design of the lining based on the type of defect and
ovality of sewer pipes. The decision to use spot, partial or
full reline repair is selected based on cost effectiveness
and the special condition of each sewer pipe. The results of
applying this approach in the rehabilitation of the Crestwood
neighborhood is discussed.

John Galleher, San Diego County Water Authority
This paper examines the use of a combination
of electromagnetic inspection, long-term acoustic monitoring
and comprehensive dynamic risk management modeling to assess
the remaining time to failure for pipe while protecting against
spontaneous rupture. This approach allows agencies to
optimize PCCP management and offers a cost-effective solution
to assuring pipeline integrity.
Robert "Bud" Swensen, Project
Engineering Consultants, Ltd., and Steve Weber, Clark County
Water Reclamation District
This paper presents the results of an assessment
of the Clark County Water Reclamation District (CCWRD), Las
Vegas Valley, collection system. CCTV investigations of the
interceptor found the Crosstown Interceptor PVC-lined RCP to
be in generally good condition but repairs of the detached
weld strips will be required in the near term to deter corrosion
of the concrete in the sewer line.

and Mike Harmer, New Castle County
This paper discusses how the physical condition
assessment of the Northcrest and Afton neighborhoods in New
Castle County, DE drove the selection of rehabilitation technologies,
how specific technologies were selected, how the construction
of these was accomplished, and how effective these methods
were in reducing I/I. The paper includes cost data and pre-
and post- rehab effectiveness flow data from the project.

This paper presents an overview of the City of Edmonton’s
WESS inverted siphon project focusing on the design and construction of
a 3,200 mm diameter 1,150 m long tunnel beneath the North Saskatchewan
River. Design challenges and solutions will be discussed, and an
update of the tunneling progress will be provided.
Hassan Al-Barqawi, PMP, M.Sc., EPCOR Water Services

This paper presents condition rating scale and models that
can be used for prioritizing rehabilitation actions of water mains. These
models are based on the available physical, environmental, and operational
data. Case study is presented.
This paper will present both successes and failures of asset
management programs as related to water and sewer infrastructure from around
the United States.
This paper presents how the industry has to get “buy-in”
and inform all levels of a public agency and make cultural changes within
the agency if Asset Management practices are to be accepted and are to
work

This paper describes a program that introduces
a large trenchless project to approximately 60 graduating civil
engineers. The trenchless project was integrated into
the curriculum of a major university, as part of a senior capstone
program.
This paper speaks to the development of the next
phases of the Pipeline Assessment and Certification Program
(PACP) and presents an overview of the new coding used in manholes
and laterals. Photos and typical coding of pipe, manhole and
lateral defects will be shown.

This paper describes the features of a customized
design tool and streamlined design approach developed by the
City of Los Angeles that expedites the delivery of projects.
The main features of this system is a program that uses standardized
design methods and documents in combination with a new GIS

This presentation describes the Damage Information
Reporting Tool (DIRT) developed by the Common Ground Alliance
(CGA) to collect damage information. The primary purpose

them in the future; thereby, ensuring the safety and protection
of people and the infrastructure.
This paper describes 2 new “arrayed-antennae-based”
utility detection technologies, both of which avoid damage during
