Track II-C = Sewer Construction & Rehabilitation: New Technologies
8:30 - 9:55 a.m.
This session will feature several new technologies and methods that could potentially impact the sewer/water industry in the near future.

Track Moderator: Terry Anderson, Future Pipe
Part 1: Standard Cement
Speaker: Steve Henning, Standard Cement Materials
Manholes and wet-wells that are exposed to extreme environments, such as very low pH’s or very high flow rates, benefit from fiberglass-reinforced epoxy liner systems.
The PerpetuWall system differs from a previous bag system in that the wall of the manhole or wet-well is first cleaned, strengthened, smoothed and prepared by applying a cementitious liner. Exposed aggregate is easily addressed with this approach. Then the fiberglass-reinforced epoxy liner is installed by hand. By hand-applying the epoxy liner there is no need to remove existing piping, force mains or steps, while removing the potential for error in measurement and installation. Case studies and several different applications will be presented.

Part 2: Laser Profiling
Speaker: Jerry Botts, President, Botts Consulting Group LLC
A new laser profiling technology adds dimensions to conventional pipe inspection methods. The CoolVision laser profiler measures the interior ovality of most types of pipe to assist in accurately verifying the overall condition of an existing pipeline or to confirm that installation of new pipe meets ovality specifications and the verification of rehabilitation technology.

Part 3: Benefits Of New Manhole Chimney Replacement System
Speaker: Michael K. Crites, President, Critex LLC
This presentation will demonstrate the costs savings associated with total manhole chimney replacement using newly developed technology. The system reduces labor and costs, making chimney replacement and frame leveling a good investment.

PCCP Condition Assessment: Exploring Repair Solutions For Wichita Falls’ 54-Inch Transmission Line – The Rest Of The Story
Moderator: Terry L. McArthur, P.E., HDR Engineering, Inc.
Speaker: Scott Taylor, P.E., Director of Public Works, City of Wichita Falls
Speaker: Gretchen N. Williams, PE, Senior Project Manager, CDM
The city of Wichita Falls, TX, has two surface water supply sources – Lake Kickapoo and Lake Arrowhead. Water from these lakes is delivered to the city’s water treatment plant facilities through large diameter prestressed concrete cylinder pipe (PCCP) transmission mains. The Lake Arrowhead raw water transmission main is 54-in and extends over 68,500 lf. After 38 years in service, several line breaks resulted in interruption of supply. In March 2007, a portion of the Lake Arrowhead raw water line was inspected by use of Remote Field Eddy Current/Transformer Coupling (RFEC/TC) technology. Over 27,149 ft, or 1,708 pipe joints of prestressed concrete cylinder pipe were inspected for determination of the number and location of broken prestressing wires, an indicator of failure potential. The inspection indicated that 192 pipes joints had wire breaks, ranging from 5 to 60 breaks.
This paper will discuss the information received from the inspection and a computerized transient surge analysis is being used to perform a risk analysis and to prioritize portions of the waterline most at risk for failure. Final recommendations to the city will be discussed

9:30 - 10:25 a.m.

Case History: Difficult Slipline, Innovative Solutions
Moderator: Keith Hanks, Sr. Sanitary Engineer, Wastewater Conveyance Engineering Division, Los Angeles, CA
Speaker: Michael Spero, P.E., Manager of Engineering, Future Pipe Industries
Project involved sliplining 4,000 ft of 84 in deteriorated concrete sewer in Henrico County, VA, with 72-in fiberglass pipe. There were 6 curve sections with a short radius of 160 ft and a crossing of a major Interstate highway. Pipe manufacturer working with the contractor developed a special joint design to negotiate the curves and eliminate excavation and removal of the top half of the concrete pipe. Discussed will be what went right, what went wrong and how a difficult project was completed successfully.

9 - 9:55 a.m.
Liner Buckling Design Using Critical Buckling Strain
Moderator: Joe Barsoom, Chairman, TTC Industry Advisory Board
Speaker: Wei (Zack) Zhao, Ph.D., Ultraliner
Speaker: L. Grant Whittle, Vice President, Ultraliner
In North America, close-fitting structural pipe liners are designed according to the ASTM F-1216 design appendix. This design standard is based on the structural buckling theory. A long-term material elastic modulus is introduced to accommodate for material creep for a long-term design.
This paper discusses the theoretical incorrectness of applying a long-term elastic modulus in the instantaneous buckling equation, and the technical difficulties in determining the value of the modulus. Based on the critical buckling strain theory introduced in the 1960s, the authors propose a new liner design method. In the new design method, the instantaneous buckling equation is used for short-term liner buckling design, then the creep strain and the critical buckling strain theory are used to validate the long-term design.

Successful Technology for Utility Installation in Unstable Geology (60 to 96 inches in diameter)
Moderator: Brian Mattson, GTI
Speaker: Tom Fuerst, Operations/Sales Manager North America, SBU Division, The Robbins Company
This paper discusses recently employed methods for longer bores (over 325 ft) in medium to hard rock with unconfined compression strengths greater than 10,000 psi. A growing need for longer utility bores in difficult ground conditions has necessitated the use of different types of technology. One of the most efficient methods utilizes manned-entry Double Shield Tunnel Boring Machines (TBMs) ranging from 60-96 in diameter. These types of machines allow for simultaneous boring and tunnel lining in unstable geology.
A brief overview details the development and applications of small Double Shield TBMs. The paper then examines the advantages and disadvantages of the technology and its use with various types of tunnel-lining methods. Recent projects details, including operational and site requirements are also presented.

9 - 9:55 a.m.
A Core Strategy For Utility Cut Repairs
Moderator: Brian Mattson, GTI
Speaker: E. Marshall Pollock, President, Utilicor Technologies Inc
This paper discusses keyhole technology and the coring and reinstatement process that enables utility crews to cost-effectively perform repair or maintenance work on underground pipe or other buried plant from the road surface through an 18-in diameter “keyhole” cored through the pavement thereby avoiding more costly, disruptive and inherently more dangerous excavation methods.
The paper explores more than pavement management and ROW issues – it includes need for municipalities to properly locate and map their underground infrastructure. Keyhole coring and pavement reinstatement has a major application in cost-effectively locating and verifying buried utilities before installation of new infrastructure is undertaken, and is one of the key methods of avoiding cross-bores in sewer pipes.

Track IX-B = Trenchless Technical Symposium: Sewer & Water
8:30 - 8:55 a.m.
Pipebursting – A Case Study Of Positive Public Relations
Moderator: C. Vipulanandan, University of Houston
Speaker: Phil Parkins, P. E., Project Manager, Camp Dresser & McKee Inc.
Infiltration and inflow had reached critical levels in many parts of the city of Greenville, SC, sewer system when it became necessary to prioritize their rehabilitation work. High on the priority list was the rehabilitation of the Richland Creek sewer. More challenging than pipebursting the 8-in vitrified clay pipe to 12-in HDPE pipe was “selling” the project to one of the city’s most established neighborhoods.
This paper will discuss an approach involving pipebursting that would minimize or eliminate the clearing of mature landscaping along the pipeline alignment and reduce the risk of damaging structures through the use of excavation equipment. It will further outline the comparison between open-cut installation and pipebursting and highlight the advantages that were realized using Engineer Procurement-Construction Management as the project delivery method.

9 - 9:25 a.m.
Zaragosa 36-Inch Waterline Replacement Project: Slipline Rehabilitation Of El Paso Water Main With Fusible PVC
Moderator: C. Vipulanandan, University of Houston
Speaker: Joseph M. Moreno, Brown And Caldwell
An existing 36-in pre-stressed concrete steel cylinder pipe (PCCP) had been installed in three segments from 1959 to 1973 along Zaragosa Road in El Paso, TX. The 16,300 ft of water main had failed numerous times over the past 6 years, causing residential and highway flooding. The waterline was in need of substantial repairs. After extensive analysis it was determined that sliplining the existing line would be the most cost effective and least disruptive solution. The use of 80-ton static pipebursting equipment allowed sections up to 1,800-ft long of the 24-in DR 25 Fusible C-905 to be inserted into the existing host pipe as a single pull.
This paper will discuss how this project was successful due to careful planning and project alternative evaluation, by utilizing emerging technologies and trenchless construction methods and a strong project team from conception and evaluation through construction and project completion.

9:30 - 9:55 a.m.
