Municipal Case Study Series: City of Regina-Stantec
Construction of a 60-Inch PVC Force Main
Ideal
for Sewer Utility Engineers, Installation and
Maintenance Staff, Consulting Engineers, and
Contractors
 Welcome
to the PVC Pipe Association’s (PVCPA)
municipal case study webinar series, featuring
presentations from leading wastewater and
waterworks experts. The third webinar in our
series examines important topics on the
design, construction, and testing of a large
diameter PVC force main: the “Regina 60-inch
PVC Third Sewage Force Main.” Following
rainfall events in 2015 when surcharge
sanitary flows discharged to nearby Wascana
Creek, the City of Regina agreed with the
Saskatchewan Water Security Agency to system
upgrades that could handle a 1:25/year 24-hour
flow to the wastewater treatment plant. The
“Third Sewage Force Main,” along with upgrades
to the McCarthy Boulevard Sewage Pumping
Station, increased the station’s capacity to
be able to manage 1:25/year flows now and into
the future without bypasses to Wascana Creek.
Michael
Georgalas, P.E., Senior Hydraulics Engineer at
Stantec, will lead the
discussion along with Regina official Wenqing
(Jennifer) Yang, P. E., and cover key aspects
of this project including benefits to the City
and challenges associated with design,
installation, and testing of the force main
due to its large size. These included design
of unique thrust blocks, re-design and
fabrication of PVC to steel flanged coupling
adapters by the manufacturer, fabrication of
bends to minimize the need for thrust blocks,
and hydraulic capacity testing of the
pipeline. In addition, as part of the
 force
main design, a transient analysis was
completed to determine appropriate opening and
closing times for the 36-inch (900 mm) flow
control valve used to divert flows
into the force main.
The presentation will include a review by
PVCPA Regional Engineer Jay Parvez, P.E., of
the PVC pipe industry’s new online calculator
for determining the cyclic life of sewer force
mains. Design procedure and examples
will be provided, along with additional
considerations. The calculator is used in
conjunction with the new “Force
Main Design Guide for PVC Pipe,” which
discusses cyclic surges in general,
introduces the
analytical method used by the calculator, and
provides design examples
for better understanding of the subject. Using
the cyclic procedure provided in the guide
enables a thorough analysis of a PVC force
main project.
Featured Presenters
Michael Georgalas, P.E., is a Senior
Hydraulics Engineer at Stantec
and has extensive experience conducting fluid
transient analysis and mitigation design for
existing and new water and wastewater systems.
He has completed more than 140 hydraulic
transient (water hammer) projects at locations
throughout North America. These included the
analysis of existing and proposed systems to
quantify the magnitude of potential pressures
experienced under various transient-inducing
events, and recommending measures to eliminate
or mitigate them.
Wenqing
(Jennifer) Yang, P.E., is Project Engineer
at the City of Regina. She holds a Master of
Applied Science (MASc) degree in Environmental
Engineering from University of Regina. In her
role at the City, she has planned and managed
various capital projects for Regina’s water
and wastewater infrastructure. These included sewage force main
inspection and construction, water main and
lift station condition assessment, domestic
sewer flow monitoring, and construction of
water pump and wastewater lift stations.

Webinar: Tapping Small- and
Large-Diameter PVC Water Pipe
Ideal
for Water and Sewer Utilities, Engineering
Consultants and Installers
 PVC
Pipe Association (PVCPA) staff will review
tapping procedures for both small- and
large-diameter gasketed PVC pressure pipe. The
presentation will include instructional
diagrams and photos. “Tapping” involves
drilling a hole into a main-line pipe to
attach a branch line. It’s often done with the
main line under full pressure so specialized
techniques have been developed to streamline
the installation process.
This 30-minute webinar will discuss proper
tapping techniques for gasketed PVC water pipe
and include the following topics:
-
Introduction
-
Direct tapping
-
Saddle tapping
-
Sleeve tapping

Webinar: Installation of PVC Water and Sewer
Piping Systems
Ideal for Water and Sewer Utility Engineers,
Contractors, Inspectors, Engineering
Consultants and Developers
This training webinar by PVC Pipe
Association (PVCPA) staff will provide the
most up-to-date information available on
installation practices for gasketed PVC water
and
 sewer
pipes and fittings as well as answer
frequently asked questions. Properly installed
pipelines ensure best performance and maximum
design life for underground infrastructure.
All Participants Receive a FREE Copy of
the Contractor's Guide for Installation
of Gasketed PVC Pipe
The reference book for this educational
seminar is the new Contractor's Guide,
which is the most concise, authoritative
publication available for the installation
of gasketed-joint PVC pipes and fittings.
Webinar registrants will be mailed a FREE
copy. Written and sponsored by PVCPA, the
guide comes complete with practical tables
and figures that helps users to be more
effective and efficient at installing PVC
piping systems, reducing potential
pipeline problems and helping to ensure
optimum system performance. It can also
serve as a reference document prior to
undertaking a pipeline project.
Recommended for Local Underground Pipeline
Installation Contractors
It is highly
recommended that local water and sewer pipe
installation contractors participate in this
training seminar. Utilities are encouraged
to forward this email to their local
underground pipeline contractors and have
them register. The guide is also useful to
utility crews involved in installation or
maintenance of PVC water or sewer systems.
The easy-to-use, "reversible book" format
provides two valuable guides in one and
assists readers to quickly access the
information they are seeking.
The 60-minute webinar will cover the
following topics:
-
Manufacturing and plant testing of PVC
pipe
-

Webinar: Considerations for Pipe Material
Selection: PVC vs. Ductile Iron (DI) Pipe
Ideal for Water Utilities, Engineering,
Consultants, Contractors and Government Agencies
 Today's
marketplace offers North American utilities a wide variety of piping to choose
from. Pipe materials can differ significantly in performance capabilities and in
the applications for which they are suitable. As a result, making direct
comparisons between pipe materials can be challenging for utilities. This
webinar will compare PVC and ductile iron (DI) pressure pipe with respect to
their properties, design methodologies, installation requirements, and long-term
performance in various applications. The information will help utilities that
use both piping materials to make better informed decisions for their projects.
This one-hour webinar covers the following topics:
-
History and background of PVC and DI pipe
-
Hydraulics of PVC and DI pipe
-
Design considerations for PVC and DI pipe
-
Installation requirements for PVC and DI
pipe
-
Pipe material longevity and performance

Webinar: External Load Design for PVC Gravity
and Pressure Pipes
Ideal for Designers, Reviewers, Regulators and
Managers of Piping Systems
 PVC
Pipe Association staff will review information on the use of PVC gravity sewer
and water in deep-bury applications. This webinar will address a subject
commonly misunderstood by design engineers: flexible pipe design as it pertains
to deep-bury installations. Some engineers and utilities across the country have
arbitrarily set depth-of-bury limits for PVC without a complete engineering and
installation analysis. Staff will review flexible pipe design and important
engineering considerations for deep-bury projects. This presentation will
explain how the pipe/soil structure provides the strength for PVC sewer and
water pipe in buried applications.
This one-hour webinar covers the following topics:
-
Definition of pipe stiffness
-
Definitions
for flexible pipe and rigid pipe
-
How pipe
stiffness is determined
-
Comparison of
pipe stiffness for different pipes
-
Trench types
-
Soil stiffness
