Available in PDF, EPUB and Kindle. Book excerpt: Undoubtedly, potable water pipes, as part of an underground infrastructure system, play a key role in maintaining quality of life, health and well being of human kind. As these potable water pipes reach the end of their useful life, they create high maintenance costs, loss of flow capacity, decreased water quality, and increased dissatisfaction. Trenchless renewal methods (TRMs) are a medium to renew deteriorated potable water pipes, thus decreasing leakage loss, emergency maintenance costs and customer complaints. TRMs also maintain the quality of the water leaving the treatment plant. America's drinking water systems faces an annual shortfall of at least $11 Billion to replace the aging facilities that are near the end of their useful lives and to comply with existing and future federal water regulations (ASCE, 2009). Due to applicability, capabilities and limitations of specific trenchless renewal methods, it is sometimes difficult to select an appropriate method for a particular pipe conditions and based on the project surface and subsurface characteristics. To assist with solving this problem, this research presents a comparison of trenchless renewal methods as well as a decision support system and a cost module to select a suitable trenchless renewal method based on the particular pipe problems and field characteristics.

This book was released on 2017 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trenchless renovation has been in operation since the 1970's in North America and the United Kingdom. However, it has not been widely accepted due to cost effectiveness concerns. Many Canadian cities are faced with the problem of aging and deteriorating water distribution network due to one or a combination of pipe breaks, leakages, or aesthetic water quality problems, resulting from aging and internal corrosion. Various polymer-based products such as Cured-in Place Pipe (CIPP) lining have been widely employed in structural water main rehabilitation applications. On the other hand, only a few technologies deal with non-structural systems, usually meant to serve as barrier coatings thereby protecting the iron water mains. This thesis presents the results of a laboratory testing program designed to investigate the renewal of potable water mains via the use of polyurea and epoxy-polyurethane lining in two separate locations in Ontario. The effectiveness of using these polymeric linings are investigated, available and new cleaning technologies are discussed, and thereafter properties of the tested liner material are verified. There are two primary objectives for this research. They include 1) evaluation of the lining products, which are installed using new technologies, and 2) development of testing protocol to address construction Quality Assurance/Quality Control (QA/QC) concerns for the new technologies. Employing a spray-on liner in trenchless technology applications provide several challenges including unknown pipe life, unknown corrosion rate in pipes, and pipe-liner material interaction (in form of bond). This research incorporated some trial sites to gather field data related to the primary objectives described above. The trial site is located at the 3M Oxford street facility, located in London, Canada. The field installation of liners into pipe sections are put into practical demonstration and samples are tested for as per quality control. Finally, it is concluded that using an effective pipe cleaning method eradicates lining faults and improves adhesion to the host pipe. Also, a strategic QA/QC test protocol is developed.

This book was released on 2007-01-22 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protecting and maintaining water distributions systems is crucial to ensuring high quality drinking water. Distribution systems-consisting of pipes, pumps, valves, storage tanks, reservoirs, meters, fittings, and other hydraulic appurtenances-carry drinking water from a centralized treatment plant or well supplies to consumers' taps. Spanning almost 1 million miles in the United States, distribution systems represent the vast majority of physical infrastructure for water supplies, and thus constitute the primary management challenge from both an operational and public health standpoint. Recent data on waterborne disease outbreaks suggest that distribution systems remain a source of contamination that has yet to be fully addressed. This report evaluates approaches for risk characterization and recent data, and it identifies a variety of strategies that could be considered to reduce the risks posed by water-quality deteriorating events in distribution systems. Particular attention is given to backflow events via cross connections, the potential for contamination of the distribution system during construction and repair activities, maintenance of storage facilities, and the role of premise plumbing in public health risk. The report also identifies advances in detection, monitoring and modeling, analytical methods, and research and development opportunities that will enable the water supply industry to further reduce risks associated with drinking water distribution systems.

Available in PDF, EPUB and Kindle. Book excerpt: Comprehensive Water Quality and Purification, Four Volume Set provides a rich source of methods for analyzing water to assure its safety from natural and deliberate contaminants, including those that are added because of carelessness of human endeavors. Human development has great impact on water quality, and new contaminants are emerging every day. The issues of sampling for water analysis, regulatory considerations, and forensics in water quality and purity investigations are covered in detail. Microbial as well as chemical contaminations from inorganic compounds, radionuclides, volatile and semivolatile compounds, disinfectants, herbicides, and pharmaceuticals, including endocrine disruptors, are treated extensively. Researchers must be aware of all sources of contamination and know how to prescribe techniques for removing them from our water supply. Unlike other works published to date that concentrate on issues of water supply, water resource management, hydrology, and water use by industry, this work is more tightly focused on the monitoring and improvement of the quality of existing water supplies and the recovery of wastewater via new and standard separation techniques Using analytical chemistry methods, offers remediation advice on pollutants and contaminants in addition to providing the critical identification perspective The players in the global boom of water purification are numerous and varied.

This book was released on 2012-12-06 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decade, the field of trenchless technology has expanded rapidly in products, equipment, and utilization. This expansion would not have occurred without a strong increase ineconomic incentives to the user. Because theoperating environment has changed, trenchless technology is often the preferred alternative to traditional methods of digging holes and installing conduits. The infrastructure in which we live has become more congested and has to beshared by several users. In addition, the cost of restoring a road or landscaped area after construction may be higher than the cost of installing the conduit. These factors add to the need for trenchless technology-the ability to dig holes without disturbing the surface. In some ways, trenchless technology is a futuristic concept. Ruth Krauss in a children'sbookofdefinitions wrote,"AHole...Is to Dig." But thisstatement is not necessarily true. Today, a hole could be to bore. Trenchless technology is not new. But it certainly has become the buzzword of the construction industry and it appears that it will have a growing impact in the way contractors, utilities, and others install new facilities. Methods to bore horizontal holes were practiced as early as the 18005, but this technology has greatly changed. Today's tools include sophisticated drilling methods, state-of the-art power systems, and electronic guidance techniques. These tools can bore faster, safer, and more accurately, and in many instances more economically, than open-cllt methods. Technology has played an important role in these advances, but economics has become the driving force in making these systems popular.
