UPDATED FOR 2010! -This workshop teaches a strategy for conducting a successful municipal sewer rehabilitation program for SSO and I/I 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 pay-back 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. New material this year will include a comparison of methods to determine rehabilitation effectiveness. The popular method of using "R" values (% 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. This is a "how-to" seminar that will equip people for starting an I/I reduction program and the information will also provide valuable benchmarks for people who are actually conducting programs. Presented by noted engineering project managers and researchers George Kurz of Barge Waggoner Sumner & Cannon, and Pat Stevens of ADS Environmental Services. The full day workshop includes lunch, hand-outs and CEU/PDH credits
This workshop is being conducted by ASCE's Manhole Rehabilitation Task Committee and will provide guidance on developing and implementing a manhole inspection and rehabilitation program using ASCE's MOP 92.

Elmendorf Air Force Base is faced with deteriorating water mains which regularly cause breaks and service stoppages. The high cost of replacement of water mains and the social costs associated with conventional replacement methods have motivated Elmendorf to try new and innovative technologies for the structural renewal of their water mains. The depth of bury and the location of the asbestos cement water main on Elmendorf has made pipe replacement with traditional open cut methods prohibitive. In addition, the presence of service connections motivated the Elmendorf Civil Engineer Squadron to suggest the use of a cured-in-place pipe (CIPP) technique with the capability of reinstating the service connections from inside the pipe.

The Flores Street storm sewer improvements trenchless project is Phase 1 of the city of Laredo's efforts to eliminate illegal or illicit sanitary sewer connections and improve the existing storm water drainage system. The project site is located along Flores Street, and extends southward from Iturbide Street to Water Street into the city of Laredo's San Augustin Historic District. Because the sewer line is located in the historic district, minor surface disruption was an essential element desired by the city. This project consists of 1500 LF of combined sewer due to the illegal connections. The sewer will be rehabilitated and turned into a separate storm sewer and sanitary sewer directed to a manhole. A 42" sanitary sewer line was installed by tunneling below an existing 24-line sewer line to separate the storm sewer and sanitary sewer systems. Estimated cost of this project is $ 2,700,000.00.

Municipal sewerage systems have precipitously become more corrosive due to increased biogenic sulfide corrosion activity. This corrosion mechanism is a bacterially mediated process of forming hydrogen sulfide gas and the subsequent biological conversion to sulfuric acid that attacks concrete and steel within wastewater environments. Traditional bonded coatings, as well as new high performance spray applied, protective lining technologies, are routinely failing in severe manhole environments. These failures are attributed to many factors including low permeability properties to resist H2S and other sewer gases present within these environments. This session will explain the biogenic sulfide corrosion process and inform the audience of an advanced laboratory testing protocol for rapidly evaluating the performance of protective linings in a simulated wastewater head space environment.

More than 3 million miles of electrical cables, and 180 million miles of telephone and cable TV lines are strung overhead across the country. But cost benefits accruing from reducing day-to-day maintenance and operating costs, improving reliability, enhancing public safety and improving aesthetics and property values, are leading more and more utilities and municipalities to the realization that converting overhead distribution lines to underground is the best way to provide high-quality service to their customers. Public policies are being developed which consider some form of cost-sharing for undergrounding, as governmental agencies learn more about the benefits which accrue to themselves and to utilities, developers, homeowners, businesses, communities and other rate payers, as a result of undergrounding. This presentation will address the evolving technology and reliability being seen in HDD, materials such as cable and physically locating underground utilities, and the future impact on the entire underground construction industry.

Long term durability of carbon fiber reinforced polymer (CFRP) systems used to strengthen pre-stressed concrete cylinder pipes (PCCP) and other water transmission structures has been under scrutiny since the CFRP systems were initially implemented for repair of pipelines in 1997. The Metropolitan Water District of Southern California (MWD) studied the effect of water immersion on the long term durability of CFRP samples at the MWD laboratory as a part of their ongoing CFRP research program. The CFRP samples of Tyfo SCH System from Fyfe Co., were prepared at MWD and were submerged in the year of 2000. The tensile testing according to ASTM D 3039 on the aged samples was recently performed to provide long term durability data. The results of this study will assist engineers and pipeline users in determining the applicability of a CFRP system as a long term repair solution.

ASTM International Committee F36 on Technology and Underground Utilities addresses issues associated with underground utilities in terms of use, maintenance and design. F36 is focused on water, sewer and natural gas systems in three primary areas. First, is the utilization of this infrastructure as housing for fiber-optic cable (often robotically installed). F36 has started a standards portfolio that addresses safety and access rights, selection of the utility, and the continued maintenance of the utility once fiber has been installed. Second, F36 standardizes the maintenance and rehabilitation of these systems using robotic technology and chemical grouts - and has a portfolio of guidance for information on the sealing and repair of manholes, laterals and other drainage infrastructure using these techniques. Finally, the committee is assembling an asset management reference guide in order to best direct industry to references for specific aspects of AM - and in the process, identifying gaps where future standards can be developed.

This presentation examinations the techniques surrounding the installation of segmented product pipe during static pipe bursting and what information is needed in order to effectively chose between segmented pipe options and fusion pipe options for a particular project. A local geo technical consultant should be part of the project design and planning, as soil types vary dramatically from region to region, sometimes block to block. If the soil demonstrates that it maintains an annulus for a period of time, the segmented pipe will probably work well. In free flowing sand and other similar conditions, segmented pipe may be problematic - fusion welded pipe system should probably be used instead.

The MVP Award is bestowed annually to an individual for outstanding contributions to the underground infrastructure industry. Andrew Mayer of Murphy Pipeline Contractors, 2010's recipient, was surprised to discover that pipebursting water mains using the pre-chlorination method in the United States was not a commonplace practice as it is in his native London.
Waste from the Mead-Johnson (MJ) Plant near downtown Evansville, IN, is discarded and dumped at the Laubscher Meadows Landfill (LML) owned by Allied Waste. The boilers at the steam plant were designed to consume natural gas transported via pipeline by a local utility. The landfill produces landfill gas, which is a mixture of methane and carbon, created as waste decomposes. In October 2005, CPL contracted with Bernardin, Lochmueller & Associates Inc. of Evansville to prepare preliminary plans and specifications for a unique approach: build a pipeline to capture the landfill gas and transport it back to the plant to use in lieu of natural gas. In May 2008, Miller Pipeline Corporation was awarded the contract to construct the 27,000' pipeline. Miller installed 19,850' by the HDD and 6,500' of pipe by the open-cut method. The project included two railroad crossings (by bore and jack method), four river crossings (HDD), and two state highway crossings (HDD).

There is a glaring need for condition assessment tools that will allow utilities to implement selective repair and replacement strategies based on the actual condition of the pipelines. To keep the overall project cost and effort manageable, and to maintain customer service levels, these technologies need to be able to address pipelines while they are in service. This session outlines two approaches now available for condition assessment of metallic mains while they remain in service. The first is a tethered inline inspection system which can detect discontinuities in the pipe wall, internal corrosion, damage to or loss of the liner, and is under testing for its ability to provide average wall thickness over set intervals. The second is a "smart pig"

The expanding requirements for laser and sonar pipeline profiling surveys are changing the assessment process for underground pipeline acceptance, as well as pre- and post-rehabilitation. These technologies present true condition data, not previously available from tradition CCTV surveys. Since the 1960's, CCTV surveys and walk-through have been the primary methods of determining pipeline condition. As more and more consulting engineers, municipal authorities and governmental agencies are requiring these surveys, the revenue opportunities of traditional wastewater inspection and rehabilitation contractors has increased significantly. Much of the hardware and software required is standard for a CCTV inspection contractor. Understanding these technologies, how they are used and the resulting potential benefits, including increased revenue, are the basis of this presentation. Unfortunately there is a large degree of subjectivity and concentration involved with a viewer's interpretation of visual-only information. Walk through inspection has always carried a high risk and hazard factor because it involves a confined space entry. Although CCTV surveys are a still a necessity, the addition of pipeline profiling are providing additional user and contractor benefits not possible with video only inspections.

In addition, the project called for the installation of 4-inch Fusible C900 through directional drilling along Wendover Road to enable the transfer of services from the existing location under the roadway and allow for the pipebursting of a 12-inch cast iron water transmission line. The 12-inch line was replaced with ductile iron pipe. As a result of this pilot project, the Greensboro City Council approved the Water Resources Department budget for FY 2009/10, which includes a major expansion of the program. Additional water pipe materials and diameters are also being considered for bursting.

This presentation takes audience members through a step by step method for calculating the cost of operation for a small- to medium-sized directional drill rig. All too often, the use of HDD is baffling to many when it comes to calculating operating costs and determining profitability. There is a simple and straightforward way to figure the operating cost of horizontal directional drills on operating cost per foot. Horizontal directional drills are ultimately production based products and productivity drives both operating cost per foot and gross revenues. Understanding the things that must be considered and then using those factors in an operating cost model can help to ensure that one does not venture into the realm of marginal profits or worse.

Magnetic Tomography Method (MTM) is a non-intrusive, non-contact method of inspecting pipelines. MTM provides pipeline operators with a cost effective and efficient method to assess the condition of all pipelines (made of ferrous materials) including those that cannot be inspected by available tools since the inspection is conducted from the ground surface above the pipeline. MTM principle is based on detecting and analyzing changes in the magnetic field of the pipelines manufactured with ferrous materials. These changes or magnetic anomalies form in areas of stress concentration due to excessive mechanical loading, changes in structural conditions of the pipe material or combination of the above.

Millions of sewer laterals - portions of sewer networks that connect individual properties to the public sewer network - exist throughout the United States and elsewhere. Many laterals have not been maintained and as a result, allow significant amount of inflow and infiltration (I/I) into sewer systems which can lead to sanitary sewer overflows, increased costs and damage. Consequently, there is a compelling need to solve I/I problems of sewer laterals. For more information, visit nastt.org or contact Angela Ghosh, (703) 217-1382, aghost@nastt.org.

The use of gyroscopic steering tools can save of lot of time for the HDD pilot-drilling. This steering tool also gives the highest possible precision and accuracy in any environment, regardless of the depth of the bore-hole. Gyroscopic navigation techniques for HDD also result in faster installation of the piping after reaming, because of less dogleg severity and precise control of bending radii. Besides the gyroscopes, various other down-hole parameters can be measured in real-time, such as the inner and annular mud pressure. These features, together with a direct reporting after executing of the drill-job, gives the construction company a money saving tool.

In early 2009, officials in King County, WA, addressed a hydrogen sulfide (H2S) problem in a nearly half mile stretch of concrete sanitary sewer. Rehabilitation was needed near the Lake Hill Interceptor. Engineers chose the cured in place pipe (CIPP) technology to address the corrosion problem and restore structural integrity. The project, totaling $2.6 million, rehabilitated 513 lf of 36", 1,472 lf of 42", 496 lf of 48", and 135 lf of 54" concrete sanitary sewers. While the client originally specified water inversion and water cure, they opted to go with the more environmentally friendly air inversion steam cure (AISC) process when the project was implemented. This allowed both savings for both energy and water resources. In fact, AISC uses roughly 98 percent less water than the traditional water cure. making it an excellent option in areas with scarce resources.

Concrete corrosion from hydrogen sulfide generated bacteria is not limited to concrete pipe, manholes and lift stations. Bacterial corrosion (MIC) also commonly occurs on the concrete head works and clarifiers at wastewater treatment plants. Miami-Dade Water & Sewer Authority subjected the ConShield additive for concrete to rigorous testing for five years in their most corrosive area before deciding to incorporate its standards for concrete in its sanitary sewer system. Besides specifying it for the large diameter plant piping, Miami-Dade WASA recognized the benefit of adding ConShield to its poured-in-place structures that would be subjected to corrosion. It was dosed directly into ready-mix concrete at the site to pour clarifiers 90' in diameter and junction chambers.

Horizontal directional drilling (HDD) continues to grow in acceptance as more utilities gain experience and the number of skilled HDD contractors expands. In many parts of North America, HDD has closed the installation cost gap versus direct bury. At the same time, pipe material choices in water and wastewater systems have remained largely stagnant. At the nexus of these two trends is Fusible PVC pipe. It provides a tensile strength for HDD installations that allows it to fill the gap between the other two most popular HDD pipe materials - steel and high density polyethylene.
