Available in PDF, EPUB and Kindle. Book excerpt: Asset management principles for underground pipeline infrastructure (UPI) are used by municipalities for efficient delivery of water, wastewater, and storm sewers. Due to budget constraints and limited resources, municipalities need to improve their operations, utilizing an optimum cost to provide their asset management services. Life cycle costs (LCC) include the total cost of facility ownership taking into account all capital costs, operation and maintenance costs, and renewing or disposing costs. Asset management costs include the maintenance and renewal portion of LCC. The main objective of this research is to develop asset management strategies with consideration of all the cost factors that include the concept of True Cost (TC). True Cost includes design, construction, operation, and maintenance as well as municipal administrative costs, which are not usually considered as part of the life cycle costs. For any city or municipality, infrastructure is the biggest expense and income driving potential. However, visible infrastructure which includes roads, alleys, sidewalks and storm inlets are inspected and responded to more quickly than the hidden infrastructure that includes water lines, sanitary sewer lines and storm sewers. The reason for this discrepancy is that cities address issues which are reported by their visibly-oriented citizens, plus, political entities gain public recognition by addressing visible issues. Unfortunately, most of the time, the hidden infrastructure gets ignored or does not get addressed in time to get the best value from the final investment. The result is that cities have to spend more dollars to fix the neglected problem, thereby elevating their TCs. The TC concept for this dissertation includes the sanitary sewer portion of the UPI and utilizes asset management data from construction, maintenance, and administrative costs. This information was collected from three municipalities in the North Texas area. Since TC is typically not accounted for in municipal environment, an overall understanding of True Cost will help municipalities and stakeholders determine the actual cost of the underground infrastructure. This will enable them to make better budgeting decisions when addressing deteriorating and failing infrastructure. This research has developed a framework to calculate municipal administrative cost, and thereby the TC, which can be used by cities as a tool. This dissertation also explores some of the factors affecting TC in a municipal environment. These factors include theoretical asset management, use of hot spots in geographical information systems, failed management of sanitary sewer systems including benchmarking, and social costs.
Download or read book Water Services Management written by David Stephenson and published by IWA Publishing. This book was released on 2005-03-01 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water services include water supply, sewerage and stormwater drainage. The facilities needed for these services are pipelines, reservoirs and treatment works; but the service goes beyond the infrastructure. It includes economics, billing, and business management. Although these services exist in every city, being advanced by the growing use of automation and information technology, costs are also increasing without many consumers seeing increased benefits. Customer service is therefore becoming important to the industry. Water Services Management is intended to educate engineers to manage and improve water services, rather than simply designing and constructing treatment works and distribution systems. The text covers water supply and drainage from the hydraulic and economic points of view, and while design and construction practices are reviewed, the focus of the book is on improving existing systems to turn the emerging industry into an attractive business. Topics covered include: Potable water supply, sewerage and stormwater drainage. Hydraulic management: storage, peak flow attenuation and pumping. Water quality: standards, pollution control and treatment. Infrastructure management: rehabilitation, reconstruction, upgrading and maintenance. Economic efficiency: asset management, privatization, and risk analysis. Improving economic viability via efficient use of energy and construction project management. Characteristics encountered in developing countries are also considered, including: Low cost sanitation, water supply standards and off-grid energy sources. Capacity building and appropriate technologies. Financing, operation and benchmarking.

Download or read book Asset Management Tools for Sustainable Water Distribution Networks written by Zahra Zangenehmadar and published by . This book was released on 2016 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water Distribution Network (WDN) is the most important element in water supply systems. According to the Canadian Water and Wastewater Association (CWWA), there are more than 112,000 kilometers of water mains in Canada and their replacement cost is estimated to be $34 billion. Since majority of pipelines are frequently above 100 years old, they are prone to failure and outbreaks of disease derivable to drinking water are inevitable. Breakage in water infrastructure can result in disruptions and damage to other surrounding infrastructure such as road networks or structures. Moreover, unscheduled emergency rehabilitation works can cause interruption to traffic, households and businesses. Therefore, it is important to assess the unknown condition of WDNs to find their respective rate of deterioration in order to prevent disastrous failures or sudden shutdowns. Determining pipe condition through cost-effective assessments will grant very poor condition pipes to be considered first in order to avoid related risk and devastating failures. The problem here is that in most cases, there are limited data about condition of water mains due to the underground location of the pipelines and their restricted access. Several pipes were installed 100 years ago and they have not been examined until a problem occurred. An extensive literature review shows the absence of comprehensive and generalized maintenance model for scheduling the rehabilitation and replacement of individual pipelines in the whole network based on their remaining useful life. Previous research efforts concentrated mostly on developing models, which utilize long-term data and consider solely the pipe segments not the whole network. Since pipe segments are connected together, the performance of one pipe affect the performance of other pipes in the neighborhood. This is the reason that pipes should be considered as a network rather than individual pipeline. This shows the need for a model which could forecast the behavior of each pipeline and the whole network based on available data simultaneously. This study aims to develop a model that can predict remaining useful life to optimize the needed intervention plans based on the available budget. For this purpose, a statistical condition model is developed which utilizes characteristics of a pipeline to predict its condition. In this model, Delphi study identifies the most important factors affecting deterioration of water pipelines at first, through three rounds of questionnaires sent to selected experts. The findings show that important factors are mainly physical factors such as pipe age, pipe material, etc. After that, Fuzzy Analytical Hierarchy Process (FAHP) and Entropy Shannon are employed to prioritize the selected factors in previous step and calculate their weights based on their relative importance. Results reveal that pipe installation, age and material are the most effective parameters in deterioration. These weights are used to find the condition index of the pipeline from pipe characteristics, soil and water properties. Upon determining the condition index, the remaining useful life is estimated using the developed artificial neural network (ANN). Ultimately, the budget is allocated efficiently and different repair and replacement strategies are scheduled based on the remaining useful life and breakage rate of the pipelines utilizing the developed near optimum Genetic Algorithm (GA)-based model. Data of the water distribution network of the city of Montréal is used to develop, train and validate the developed models. Results indicate that 30.7 km of the pipelines of Montreal should be replaced in the next 20 years and 2610 km are in need of both major and minor rehabilitations. This research proposes a framework for optimized replacement and maintenance plans based on the remaining useful life and condition of the pipelines which will help operators for efficient budget allocation and better management of needed intervention plans.

Available in PDF, EPUB and Kindle. Book excerpt: This is a best practice manual for addressing water losses in water distribution networks worldwide. Systems and methodologies are presented for improving water loss and leakage management in a range of networks, from systems with a well-developed infrastructure to those in developing countries where the network may need to be upgraded. The key feature of the manual is a diagnostic approach to develop a water loss strategy - using the appropriate tools to find the right solutions - which can be applied to any network. The methods of assessing the scale and volume of water loss are outlined, together with the procedures for setting up leakage monitoring and detection systems. As well as real losses (leakage) procedures for addressing apparent losses, by introducing regulatory and customer metering policies are explained. Suggestions are made for demand management and water conservation programmes, to complement the water loss strategy. Recommendations are made for training workshops and operation and maintenance programmes to ensure skills transfer and sustainability. The manual is illustrated throughout with case studies. Losses in Water Distribution Networks will appeal to a wide range of practitioners responsible for designing and managing a water loss strategy. These include consultants, operations managers, engineers, technicians and operational staff. It will also be a valuable reference for senior managers and decision makers, who may require an overview of the principles and procedures for controlling losses. The book will also be suitable as a source document for courses in Water Engineering, Resource Management and Environmental Management.

Download or read book Privatization of Water Services in the United States written by National Research Council and published by National Academies Press. This book was released on 2002-08-20 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the quest to reduce costs and improve the efficiency of water and wastewater services, many communities in the United States are exploring the potential advantages of privatization of those services. Unlike other utility services, local governments have generally assumed responsibility for providing water services. Privatization of such services can include the outright sale of system assets, or various forms of public-private partnershipsâ€"from the simple provision of supplies and services, to private design construction and operation of treatment plants and distribution systems. Many factors are contributing to the growing interest in the privatization of water services. Higher operating costs, more stringent federal water quality and waste effluent standards, greater customer demands for quality and reliability, and an aging water delivery and wastewater collection and treatment infrastructure are all challenging municipalities that may be short of funds or technical capabilities. For municipalities with limited capacities to meet these challenges, privatization can be a viable alternative. Privatization of Water Services evaluates the fiscal and policy implications of privatization, scenarios in which privatization works best, and the efficiencies that may be gained by contracting with private water utilities.
Download or read book Predicting the Remaining Economic Life of Wastewater Pipes written by Sunil K. Sinha and published by IWA Publishing. This book was released on 2011-12-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accurate prediction of wastewater pipe structural and functional deterioration plays an essential role in the utility asset management process and capital investment planning. The key to implementing an asset management strategy is a comprehensive understanding and prediction of asset condition and performance. The primary objective of this research is therefore to develop protocols and methods for predicting the remaining economic life of wastewater pipe assets. The limits of deterioration prediction capabilities are not in mathematical models or statistical analysis methods, but in lack of accurate and consistent data. This report presented the short-term phase-1 which has been completed with results from intensive literature reviews, various interviews with utilities, and pipe associations. In this phase, the research team investigated the life cycle of wastewater pipeline and identified the causes of pipe failure in different phases including design, manufacture, construction, operation and maintenance, and repair/rehabilitation/replacement. The research team has prepared various modes and mechanisms of pipe failure in wastewater infrastructure system as well as identified environmental and societal consequences of the failure. After reviewing all relevant reports and utility databases, the research team has developed a set of standard pipe parameter list (data structure) and pipe data collection methodology. The data structure has been classified into Gold, Silver, Bronze and Wood standard.

Available in PDF, EPUB and Kindle. Book excerpt: Water and wastewater infrastructure are a somewhat invisible, yet critical, part of modern life. Incredibly, many buried assets have been in service for 50-100 years and are still in good condition. Conversely, other systems fail well before their predicted design lives, causing property damage, injury, and even loss of life. In many cases, early detection could have prevented catastrophic failure, and understanding the state of underground infrastructure has become a key priority for many municipalities. Industry has responded with a number of new and innovative technologies for condition assessment, however, understanding these tools can be difficult, as many vendors treat their proprietary systems as trade secrets. Water and Wastewater Pipeline Assessment Technologies: Classification Systems, Sensors, and Results Interpretation provides a thorough guide to the technical workings of some of the most popular water and wastewater assessment technologies available, including CCTV crawlers, acoustic listening devices, laser sensors, 360 ̊ video cameras, pipe penetrating radar, and more.
