Specific details and general principles about this project will be provided which can easily be translated to efforts for other municipalities.
Reinventing The Rehab, I&I Programs In Indianapolis
Speaker: Roger Hanas, Citizens Water
In 2011, Citizens Energy Group became the new owners of one of the largest wastewater utilities in the Midwest. Due to limited financial resources, the previous owner, the Department of Public Works, spent very little money rehabilitating the collection system, which resulted in serious deterioration over the years. In response, CEG decided to dedicate nearly $10M per year to focus on structural rehabilitation as well as reduction of I&I. This presentation will share the decision process, the problems encountered and the solutions, and what future plans the CEG has for their programs.
Large Diameter Bypass Pumping In Jefferson County
Details of a large diameter sewer bypass performed in Jefferson County, AL to support a cured-in-place pipelining project provides a deeper look at the unique challenges associated with the installation and execution of a bypass of this magnitude. The bypass project used 37,500' of 18" HDPE discharge piping, making it one of the largest bypasses performed in the Southeast.
Integrating Heat Sensor Technology Within
Large Diameter CIPP Installations Pros & Cons
Speakers: Lynn Osborn, Insituform Technologies; Jack Conte, Zia Systems
In the CIPP installation process, it can be beneficial to verify the temperature along the length of the installation during the cure phase. With the use of sensors and automation, the information can be captured in real time. However, is the cost reasonable, and can the savings in installation costs and liability reduction be justified? The findings of actual CIPP installations in large sewers and the pros and cons of each will be discussed.
Assessing A Critical Interceptor In Sensitive Areas
Speakers: Russell Ford, Lockwood, Andrews & Newnam; Wayne Brown, CleanServe
The Canyon Lakes Interceptor is a crucial part of the collection system in Lubbock, TX. Constructed in 1962, the 24" and 30" line is 43,000 LF and runs through some of the city's most environmentally sensitive areas. Restoring line capacity to its 6-mgd design is critical. A proposed new WWTP will take approximately 3 mgd off the line in the future. City officials recently announced it would award a project to perform a study and to design replacement and/ or rehabilitation along with cleaning and assessment. Primary focus will be on eliminating the SSO potential, and condition assessment of the line. The city wants as little bypass pumping as possible done due to potential SSOs.
SEWER CONSTRUCTION & REHABILITATION
Hurricane Irene Damaged Culverts Rescued
Speakers: Scott Benner, Centrifugal Lining; Tom Perry, MultiUtilities Ventures When sinkholes began to appear in one of New Jersey's busiest and most vital cloverleaf complexes after Hurricane Irene in 2011, the city's department of transportation selected the quickest and most economical solution for repair. One pipe was 240 LF of 60" and another was 300 LF of 72". Both pipe sections were bituminous-coated corrugated metal pipe had been in service since the early 1950's.The difficulties of a 30-degree vertical bend, an uneven substrate and wet weather challenges after the hurricane made selecting a repair method challenging. This and more will be shared in this presentation.
Renewing Mainline Pipe And Service Lateral
Simultaneously Through Continuous CIPP
Speaker: Larry Kiest, LMK Technologies A new CIPP technology can now be used to install a mainline liner and lateral liners simultaneously, considerably reducing the amount of time that is used to install individual liners. Moreover, this method requires minimal equipment and is simple to use. The increased productivity and equipment savings will allow new installers to enter the main to lateral connection sealing market for a more economical cost as compared to traditional CIPP techniques. This new inversion method can rehabilitate lateral connections that are located at any liner position and clock reference along a mainline pipe, and can also be performed with or without a cleanout.
A case study of this process implemented in Delaware will be presented that involved the successful rehab of a 6' section of an 8" mainline pipe. The mainline pipe was connected to two laterals that were nearly 3" apart and were rehabilitated at the same time.
Lining Alternatives For The Oakland Macomb Interceptor Drain
Speaker: Harry Price, PE, NTH Consultants Condition evaluations of the Oakland Macomb Interceptor Drain (OMID) identified approximately 20% of the 21-mile-long drain that required rehabilitation. Laser profiling documented loss of multiple inches of the secondary concrete liner to microbially induced corrosion. The owner desired to bid multiple technologies, each with a service life in excess of 50 years; that could be installed within the operational flow constraints of the interceptor system.
To identify suitable technologies a Request for Technical Submission (RFTS) was prepared and publically advertised. The RFTS provided an overall view of known physical and operational conditions of the system. In addition, the RFTS provided guidelines for the structural evaluation of the respondents to allow the owner and design engineer to compare each system. Based on the results of the RFTS, the lining specifications for OMID Contract 4 were developed.
TRA Central Regional Wastewater System Assessment Program
Speakers: Bart Hines, Trinity River Authority; Wayne Brown, CleanServe
Since it first began operations in 1959, Texas River Authority's (TRA) Central Regional Wastewater System has undergone many upgrades and expansions, resulting in a maze of underground lines. Some of those lines are very old, and exact locations and physical properties are unknown. TRA recognized the need to confirm and consolidate information on these lines, and to record the information in its GIS. TRA selected a team to clean, assess the pipe condition and perform GIS mapping of all plant drain lines from various treatment units, manholes and other structures involved in the treatment process. This project does not include the plant's storm sewer drainage system. The total project is about 34,000 LF, ranging from 2" to 60" diameter.
The Backbone Of Your Collection System: Large Diameter Pipe Inspection & Cleaning
Speaker: Jimmy Stewart, Brenford Environmental Systems

11 a.m.-11:55 a.m.
Void Detection Technologies
Speaker: Erez Allouche, Louisiana Tech University
Video inspections are limited in theft ability to provide useful information about the conditions of the interior walls of the pipe and cannot gather information about conditions of the environment surrounding the pipe. Innovative solutions are needed to allow early detection of a greater variety of problems invisible to the human eye so that system owners can reduce the risk of failures, extend the useful life of the infrastructure, and control expenditures by prioritizing the scheduling of maintenance, repair and replacement.
This session will present case histories where emerging inspection technologies were deployed to detect defects within or outside the pipe wall.
Developing Defect Codes For The Condition Assessment Of Pressure Mains
Speaker: Kelly Derr, PE, Brown & Caldwell Because the failure modes for pressure mains are significantly different in many respects to the modes of failure of gravity mains, only a few of the NASSCO Pipeline Assessment and Certification Program (PACP) codes are transferrable. What is more, the failure modes can be very different for each major pipe type. The most difficult aspect of this work will be assigning severity ratings to the defect codes. This session describes the work undertaken to date to develop a usable defect coding structure for pressure mains. The initial defect codes and their descriptions will be provided along with an initial review of severity ratings and their basis for each pipe type.
Design Considerations For Cured-In-Place Pressure Pipe Applications
Speaker: Norman (Ed) Kampbell, PE, Rehabilitation Resource Solutions This presentation will discuss the design approach for calculating the thickness and types of reinforcing materials available for liner fabrication. Information will be provided for the proper location and placement of the reinforcing materials to sustain long-term pressure cycling of the pressure pipe.
Resins And Reinforcing Materials That Are Applicable To Pressure Pipe Applications
Speaker: Kaleel Rahaim, Interplastic Corp. This presentation win provide an overview of different resin systems used for CIPP pressure pipe application. Information will be provided on how these resin systems interact with reinforcing materials to provide a pipe that will sustain pressure.

Speaker: Kent Weisenberg, Quest Inspar Attendees at this presentation will acquire new knowledge about the advances in polyurea liner technology that is enabling major utilities to rehabilitate long-in-use pressurized pipelines with in-place remediation at a lower net cost than excavation and replacement. A comparison study made by the city of Tacoma, WA will present options explored and the findings on comparative costs and benefits.
Pressure Pipe Rehabilitation During Hurricane Sandy
Speaker: David Rosenberg, Insituform Technologies/Aegion
Of all the challenges a pipeline project might encounter, Mother Nature is by far the most unpredictable. In 2012, an 8,200' pipe rehabilitation project faced several challenges when it was interrupted by Hurricane Sandy on the East Coast. All work came to a halt, the crew evacuated, and all equipment and materials were moved to higher ground with only 24 hours' notice.
The project consisted of two sanitary sewer force mains, one 8" diameter pipeline measuring roughly 4,100' in length and another 12" line also measuring approximately 4,100 LF. The original host pipe was a class 50 ductile iron pipe located in the Borough of Beach Haven, NJ and a vacation town along the Atlantic Ocean. The project involved 10 separate installations--a total of five installations for each of the parallel lines.
This presentation will highlight the project and how the crew handled the multiple challenges faced by the devastating storm.
JEA Utilizes Innovative CIPP Solution On Caper Road Force Main Rehabilitation Project
Speaker: David Kozman, RS Technik Jacksonville Electric Authority (JEA) has limited options to repair their aging pressure pipelines, and in the past has used conventional open cut repair methods. They have a growing need to rehabilitate their system and are exploring new, innovative solutions while minimizing impact and disruption to their customers.

U.S. Supreme Court Rules In Favor Of Oklahoma Vs. Tarrant County
Speaker: Wayne Owen, Tarrant Regional Water District In 2006, Tarrant Regional Water District filed suit in Federal Court seeking to abolish Oklahoma's embargo on the sale or transfer of water to Texas as unconstitutional. Seven years later, the U.S. Supreme Court has denied Tarrant's claim under the Red River Compact that the equal apportionment of water among the Compact's four states does not preclude Oklahoma's ability to prevent Texas from accessing its apportionment of water from within Oklahoma. If a Compact is silent regarding specific rights and obligations, no rights are to be inferred. Now what?
Joint Seals--A Solution to a Leaky Problem
Speakers: George Logan, Aquarion Water; Leonard Assard, PE, Heitkamp
A 30" diameter cast iron transmission installed in the early part of the 20th century traveled some 3,000' through an environmentally sensitive area. Much of this line was inaccessible because of ground water and soil conditions. Joint leaks that had occurred at the edge of the environmentally sensitive area caused the utility to investigate their options to prevent these from becoming an issue in the future. Several options were considered with joint seals being chosen as the best alternative.
Status Of Direct Potable Water Reuse In Texas
Speaker: Ellen McDonald, Alan Plummet Associates This presentation will provide a review of the status of potable reuse projects in the state; provide a summary of potential issues and challenges related to implementing potable reuse projects; and provide an update on the status of several initiatives focusing specifically on direct potable reuse.

Properly preparing for any HDD job, large or small, often makes the difference between profit and loss. Contractors frequently overlook this seemingly obvious approach.
Risk Assessment: Owners
When an owner plans an HDD project, what are the key factors to consider? What are the risks and consequences of an HDD project? What contingencies should be planned for? How can they better coordinate with contractors to minimize risks and better ensure success? In this session, owners will relate their approach to addressing any risks that may be germane to an HDD project.
What Every Engineer And Owner Needs To Know About HDD
While many engineers are being asked to design HOD projects, too often their knowledge base of this unique construction method does not allow them to comprehend the various facets of this relatively new approach to underground installations. This session will explain how engineers can better grasp the process and, in turn, design a better HDD project.
Birkdale Lift Station, Force Main Project For Kerrville, TX
Speakers: Charles Kucherka, PE, Freese and Nichols; June Baterina and Richard (Bo) Botteicher, PE, M.ASCE, Underground Solutions Inc.
The city of Kerrville required replacement of the existing Birkdale Lift station with a 9.5-MGD 4 pump lift station, to be completed in two phases. The upgrade also required approximately 8,500 LF of 20" force main pipe to be constructed. 1,160 LF of the force main had to be directionally drilled underneath the Guadalupe River with depths reaching up to 50' and soil conditions comprised almost entirely of competent rock. The force main also included two TxDOT road crossings that were to be bored and approximately 1,700 LF of construction within TxDOT right-of-way.
The design, bidding, and construction phases of the Birkdale Lift Station and Force Main Project will be outlined. It will focus on the HDD portion of the project and provide owners, engineers, and contractors with a case study example of difficult drilling and constrained layout conditions and how they were navigated to obtain a successful directionally drilled installation.
Essentials Of Contract/Sub Contract
HDD presents a unique approach to standard construction practices. Too often, conventional construction contracts are inadequate or too limiting for HDD work. What should go into an HDD project contract?
The Rock Challenge
From selecting the right tool, to steering in rock to consideration of modern construction methods, this session will cover the essentials of successful rock drilling.
The Rock Challenge, Fracturing Rock
Speakers: Bruce Beatty and Juan Ibarra, Atlas Copco CMT USA
The session will provide a better understanding on how tool selection, weight on bit and RPM's impact tool life and penetration rates in rock drilling. Topics will include rock properties, rock cutting process, cuttings generation, drilling parameters and cutting structures.
Productivity In HDD
Presented by the Distribution Contractors Association
Moderator: Samuel Ariaratnam, PhD, PE, Del E. Webb School of Construction/Ira A. Fulton School of Engineering, Arizona State University Regardless of the size and scope of an HDD project, one of the main concerns is "how can we be more productive?" The end-result, of course, is making more profit and at the same time offering a top quality product and/or service. Anyone associated with HDD should be interested, from the HDD sub contractor to the general contractor to the owner/ operator. Panelists will focus on this topic so the attendees can leave with ideas and procedures in hand that can make their companies a more valuable operation in the sphere of HDD.
DAMAGE PREVENTION & SAFETY CONFERENCE
Speaker: Walt Kelly, Industry Consultant One-Call regulations and procedures vary from state to state and are continually changing. This session reports on recent changes, pending legislation, and trends in enforcing one-call regulations.
Test Holes (Potholing) From A Contractor's Perspective
Speakers: Brent Anderson and Tyler Koll, Subsurface Utility Exploration
Making test holes (potholes) to visibly confirm exact locations of buried utilities is becoming increasingly common and sometimes required, and work often is performed by specialist contractors. Representatives of experienced contractor share information about techniques and the equipment used to make test holes.
Subsurface Leak And Erosion Void Detection
Speaker: Gary Well, PE, C.P.I.M., EnTech Engineering

WEDNESDAY, JAN. 29 TRACK II-C
Sewer Rehabilitation Strategy Workshop
Speakers: George Kurz, PE, DEE, CH2M Hill; Pat Stevens, PE, ADS Environmental Services This workshop teaches a strategy for conducting a successful municipal sewer rehabilitation program for SSO and l/l reduction. The strategy is based on extensive before-after flow measurements for 27 project areas, which included 95 miles of sewer lining, and manhole and service lateral rehabilitation on all lined sewers. The strategy proved the value of the System Approach for comprehensive rehabilitation of deteriorated sewers targeted in priority basins rather than a "find-and-fix" approach for scattered individual pipe defects. Municipal sewer O&M savings generally resulted in a payback period of about 10 years for project construction costs. The approach has been formulated into a logical and intuitive 10 step strategy. Pitfalls for flow monitoring and the analysis of monitoring data will be explained.
Included will be a comparison of methods to determine rehabilitation effectiveness. The popular method of using "R" values (percent of rainfall volume that enters a sewer line) will be compared to the Standardized Procedure which was used to document successful I/I removal in Nashville, TN. Also incorporated will be the results from a new state-wide study of I/I in Tennessee municipal systems that show there is significant leakage in municipal systems.
SEWER CONSTRUCTION & REHABILITATION
Liner Saves Collapsing Corrugated Storm Pipe
Speakers: Anita Clyne, Utility Asset Management; Terry Moy, PE, Clayton County Water Authority Lake City, GA is part of the Atlanta metro core and like other cities in this densely populated area new construction has overgrown a lot of existing underground assets, making rehabilitation of existing infrastructure a challenging and, in some cases, an impossible proposition.
This was certainly the case when the Forest Parkway culvert failed. The 66" CMP culvert was 20' deep, 220' long, and was failing so dramatically that parking lots and commercial buildings overhead were subsiding noticeably and had to be monitored throughout subsequent rehabilitation. Inspection revealed inverts that were completely corroded, sidewalls that were curling up into the pipe interior, and some sections of the pipe that were already collapsed.
Using a combination of chemical grout for severe leaks, tunnel liner plates to prevent collapse and centrifugally cast concrete pipe (CCCP) to reinforce and seal the entire length, the pipe was structurally rebuilt in place.
Indianapolis Deep Tunnel Storage System Construction Update
Speaker: John Morgan, Citizens Energy Group The presentation provides an update regarding the construction of the first combined sewage storage tunnel under construction in Indianapolis for Citizens Energy Group. As with any project, many challenges were encountered in the early phases of construction. Some of the experiences encountered as well as lessons learned during construction will be shared. The project overall consists of 8 miles of 18' diameter finished tunnel with 8 drop shafts. The depth of the project is approximately 250' below grade. Construction of the project is currently ahead of schedule.
Granite City Under Siege, Rehab Aftermath
Speakers: James Bohn, Visu-Sewer of Missouri; Steve Osborn, Juneau & Associates Granite City, IL experienced chronic problems with sewer failures, sinkholes and even collapsed reads. With partial funding from EPA, Granite City rehabilitated 15,600' of large diameter concrete pipe ranging from 72" to 108" in diameter exclusively with chemical grout. Small diameter pipe was repaired with cured-in place lining.
Now the project is complete, the question is, "Are the expectations holding up while the region is under siege again with floods and extremely high ground water tables?"
This presentation will give proof statements including photographs, MGD processing facts from the treatment plant, SSOs at peak flows (this year versus previous years), and ROI from the perspective of city officials at Granite City. Equally important, what would the consequences be this year if they were NOT proactive last year? The health and safety of the community lies in the fate of this project.
Advanced Geopolymer Lining Systems: Non-Circular Infrastructure Restoration
Speakers: Steve Henning, Inland Pipe Rehabilitation; Luke Keenan, Milliken/GeoTree Technologies This session will focus on the latest advancements using geopoiymer lining to structurally rehabilitate nonround pipes, made of various materials. Case histories will support the viability of this technology.
The Evaluation of Geopolymer Concrete Against Microbial Induced Corrosion (MIC)
Speaker: Mohammad Sufian Badar, Louisiana Tech University Corrosion is a major form of deterioration in concrete structures. According to a report published by the U.S. FHWA 2002, the cost of corrosion in water and wastewater conveyance, storage and treatment facilities in the U.S. is about $138 billion per year.
A main form of corrosion in wastewater collection systems is Microbial Induced Corrosion (MIC). However, the conditions present in an industrial or municipal wastewater pipes, or storage facility are induced by the production of sulfuric acid by biological corrosion, which cannot be fully mimicked by simple acid corrosion.
The present study intends to provide similar conditions inside pipe specimens that mimic a true sewer atmosphere. Sulfate reducing bacteria (Desulfovibrio desulfuricans) will be inoculated in the pipes. The hydrogen sulfide will be metabolized by sulfate oxidizing bacteria, producing sulfuric acid. This study shows that GPC pipe is the most resistance to MIC.
Applications Of Pipe Penetrating Radar For Advanced Pipe Condition Assessment
Speakers: Csaba Ekes, PhD, PGeo., SewerVUE Technology; Robert Lee, Brown and Caldwell Pipe Penetrating Radar (PPR) is the underground in-pipe application of GPR, a non-destructive testing method that can detect defects and cavities within and outside mainline diameter (> 18 in / 450mm) non-metallic (reinforced concrete, vitrified clay, PVC, HDPE, etc.) underground pipes. The key advantage of PPR is the unique ability to map pipe wall thickness and deterioration including voids outside the pipe, enabling accurate predictability of needed rehabilitation or the timing of replacement. By having this information available, engineers and municipalities can better estimate the remaining life left in a pipeline, refine timing of repairs, and ultimately better allocate funding for asset management.
Presented will be the recent advancement of PPR inspection technology together with selected case studies from the U.S. and Canada. The robotic Vancouver, WA case study is discussed in detail.
SEWER CONSTRUCTION & REHABILITATION
Microtunneling Option Considered For Wastewater Interceptor Realignment Across Shallow Bay
Speakers: Karen Stafford-Brown, PE, Trinity River Authority of Texas; Wayne Hunter, PE; Stephen Jenkins, PE, RPS Trinity River Authority's evaluation of 3,950 LF of a force main and 2,850 LF of gravity outfall led to a cost-effective decision to abandon an existing lift station on the edge of Mountain Creek Lake in Dallas, TX, to be replaced by a gravity wastewater pipeline along a different alignment. The least costly option included removing from service a section of pipeline tied to a bridge across Cottonwood Bay, a tributary of the lake, and replacing it with an 11' deep open-cut pipeline crossing of the bay. Environmental challenges emerged during an environmental assessment of the new alignment, resulting in a new design option being considered to cross the bay using a deep closed face tunneling system. Presented will be the considerations for establishing design alternatives for converting a lakeside 5 MGD lift station system to a gravity system while minimizing environmental impacts.
New Pipelines Provide Relief: Pilot Tube Microtunneling In The City Of Winnipeg
Speakers: Tony Janisch, Borland Construction; Chris Sivesind, Akkerman The Jefferson East Combined Sewer Relief project, owned by the City of Winnipeg Water and Waste Department, is the first in this region to feature pipe installed with pilot tube microtunneling method. General contractor, Borland Construction Inc., completed two sewer separation contracts that represent 3,300 LF of 24" to 36" I.D., 6' segment RCP in 17 drives, installed in the city's highly developed residential Scotia Street neighborhood. Running parallel to the bulk of the drives is a dike system holding the Red River at bay.
Rehabilitating Early 20th Century Bricks And Mortar With 21st Century Technology
Speaker: Mike Middleton, PE, Summit Water Consulting Long-term control plan concluded inflow and infiltration (I&I) needs to be reduced. One of the biggest problems was a meandering brick arched sewer. No records of constructing the brick arched sewers were found. From time capsule at city hall built in 1910, city meeting minutes approved labor to build part of the sewer. Approximate alignment and dimensions documented in 1956 and included varying dimensions and shapes: circular and arched with different invert materials including brick, stone and rock. Previous rehabilitation included repairing mortar and applied gunite coating at select locations in 1956 and 1975.
Systems were televised and inspected with a radio tracing device attached to camera and the signals were sent to the locating device. Determined an epoxy coating was the best rehab solution. Post construction TV inspection found isolated areas requiring additional coating budget and plan for rehabilitating remainder of sewer in future years.
Wastewater Corrosion Issues And Mitigation Strategies
Speakers: Eric Dupre', Southern Trenchless Solutions; Jason Iken, PE, City of Houston This presentation will give insight to proven and observed strategies that yield some of the best return on investments otherwise known as the "best bang for your buck" solutions. What can systems owners do better in 2014 to promote and foster better quality and long-term sustainability for their stakeholders? This presentation will provide details from corrosion programs, condition assessment, design criteria, modern day technologies, organizing a road map into your future. Getting back to the basics through cognitive thinking and better decision making on the issues at hand is the narrative for this presentation.
Solving I&I From Private Laterals: A Municipal Approach
Speakers: Alan Goodman, HammerHead Trenchless Equipment; Dave Vander Velden, Street Commissioner Village of Kimberly, WI; Mike McClone, P.L.S, Civil Engineer Tech/GIS Specialist-Village of Little Chute, WI; John Neumeier, Project Engineer-City of Kaukauna, WI; Patrick Twohig, President-Village of Campbellsport, WI; Heath Kummerow, Engineer-City of Neenah, WI
A major source of inflow and infiltration (I&I) is lateral connections. However unlike main sewer systems, laterals are typically not owned by the municipalities. This has led them to devise innovative ways to rehabilitate them. This session will review methodology of lateral replacement using pipe bursting and discuss approaches municipalities are taking to replace laterals to resolve their I&I issues. Case studies will be presented from the Fox Valley area located in Wisconsin.
ULTRAVIOLET LIGHT CURED-IN-PLACE PIPE
Integrated Design, Manufacturing, Construction Controls With UV CIPP Liners
Speaker: Grant Whittle, Reline America Using UV CIPP liners as the example, the presenter will document how to integrate quality assurance and quality control measures in an engineered product across each stage of project management to verify that the as-built deliverable complies with the original design goals. The integration of controls for the gathering, transfer and analysis of information across project phases and across parties is necessary to ensure a successful project.
Examples from Europe provide field documentation of the improvements in product performance and the cost-savings available from such planned integration of design, manufacturing and construction controls. The NASSCO PACP and ITCP programs provide guidance on how to implement successful controls with standard data capture.
Myths Of UV Light Curing Technology For CIPP
Speaker: Richard (Monte) Montemarano, MonteVista Group UV light-cured CIPP has taken a foothold in the market and continues to grow. After the initial introduction in 2005, there were many questions and rumors about the product such as engineers seeking information and clarification on what seemed to be a "too good to be true" product; and also from competitors threatened by a new European technology. Some competitors were eager to spread stories about UV credibility and specifications along with "hickups" on early job installations in the U.S. The results of these questions, stories and rumors have been a collection of mythologies about UM cured CIPR This presentation will address some of those more talked about myths and address them head-on with facts about what really happened and what is the truth about the technology.
Commitment By A Small Public Utility To Reline Its Sanitary Sewer Collection System
Speaker: Rodney McClain, Stoney Creek Sanitary District The Stoney Creek Sanitary District in the Shenandoah Valley of Virginia has over 3,000,000' of sewer mains, of which two thirds are vitrified clay and asbestos-concrete material. Poor construction techniques, roots and fractures have resulted in serious ground infiltration of water and resulting excessive wet weather flows. After 30 years of piece-meal efforts to reduce pipeline infiltration, the district invested in its own relining equipment. The result has been significantly reduced flows at a major cost savings over hiring contractors.

Also explained will be the environmental benefits of using UV GRP liners and the high strengths achieved with this technology.
Ask The UV Light Cure Experts
A panel comprised of the presenters will respond to specific questions from the audience.
Structural Evaluation Of No-Dig Manhole Rehabilitation Materials
Speaker: V. Firat Sever, PhD, PE, Benton & Associates; Mohammad Najafi, PhD, PE, F.ASCE, CUIRE-University of Texas at Arlington In the US alone, the number of manholes is estimated to be from 12 to 20 million. More than 3 million are believed to be suffering from serious structural decay and are in need of immediate rehabilitation or replacement. Manholes, although a vital part of sanitary sewer systems, are often overlooked and there are very limited studies, but numerous options to rehabilitate manholes. Sponsored by the Water Environment Research Foundation (WERF) through the EPA's Innovation and Research for Water Infrastructure for the 21st Century program, this study discusses the performance of the currently available manhole rehabilitation materials and methods based on literature search, industry professional workshop, case histories, laboratory tests, and computational modeling. Particular emphasis will be given to the structural capabilities of no-dig manhole rehabilitation materials and methods.
Manhole Rehabilitation At Denver International Airport Saves Millions
In Capital Costs
Speaker: Jeff Maier, PE, Summit Water Consulting Fourteen severely corroded, deep concrete sanitary sewer manholes and a concrete flow transition vault located at Denver International Airport were rehabilitated utilizing trenchless techniques and high performance epoxy materials in lieu of complete removal and replacement. Evaluations completed during the assessment phase of the project estimated replacement costs at $3.5M with rehabilitation costs estimated at $500,000. The final construction cost of the project was about $375,000, more than $3.1M less than the estimated replacement costs.
Design Considerations And Specification Requirements For Manhole Rehabilitation Technologies
Speaker: Craig Gaul, Parson Environmental Products Not all manholes are created equal. They can vary by location, age and construction. Because of these differences, the rehabilitation needs of each manhole may also be different. Some may need structural rehabilitation due to any one of the above reasons, while others may require resistance from unusually high levels of H2S, while still others might only need to have infiltration problems corrected. These variations in manholes and methods can occur within the same area or even on the same street. Planning is probably the most important aspect of a manhole rehabilitation project. Adequate time should be spent evaluating your problems before deciding what approach to take. A manhole rehabilitation approach that is a "one size fits all" may or may not solve the problems identified.
Longevity Of Epoxy Manhole Coatings
Speaker: Danny Warren, Warren Environmental Overview of the rehabilitation and restorations of non-conforming sewer structures, including brick, cement, metal and rock sewers. Projects showcased will illustrate structural enhancement of the nonconforming sewer and prevention of infiltration of groundwater contaminated with coal tar, oils and other petroleum products. Rehabilitation under extreme groundwater pressures and tie-ins to various other materials, such as CIP liners will also be shown.
