Download or read book Susceptibility of Distribution Systems to Negative Pressure Transients written by Kala K. Fleming and published by American Water Works Association. This book was released on 2006 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low or negative pressure transients (also called surge or water hammer) create temporary opportunities for external chemical and microbial contaminants at higher pressure to enter the water distribution system, creating potential health hazard and potential weakening of distribution pipes, leading to failure. This study investigates how such events as power outages, pump shutdowns, valve operations, main flushing, firefighting, and main breaks can create significant rapid, temporary drops in system pressure. The report offers useful recommendations for using surge models to optimally locate pressure monitors and to minimize the occurrence and impact from low- and negative-pressure transients.
Download or read book Water Systems towards New Future Challenges written by Helena M. Ramos and published by MDPI. This book was released on 2021-03-09 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book comprises components associated with smart water which aims at the exploitation and building of more sustainable and technological water networks towards the water–energy nexus and system efficiency. The implementation of modeling frameworks for measuring the performance based on a set of relevant indicators and data applications and model interfaces provides better support for decisions towards greater sustainability and more flexible and safer solutions. The hydraulic, management, and structural models represent the most effective and viable way to predict the behavior of the water networks under a wide range of conditions of demand and system failures. The knowledge of reliable parameters is crucial to develop approach models and, therefore, positive decisions in real time to be implemented in smart water systems. On the other hand, the models of operation in real-time optimization allow us to extend decisions to smart water systems in order to improve the efficiency of the water network and ensure more reliable and flexible operations, maximizing cost, environmental, and social savings associated with losses or failures. The data obtained in real time instantly update the network model towards digital water models, showing the characteristic parameters of pumps, valves, pressures, and flows, as well as hours of operation towards the lowest operating costs, in order to meet the requirement objectives for an efficient system.

Download or read book On site Generation of Hypochlorite written by American Water Works Association and published by . This book was released on 2015 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: As more water systems turn to safer alternatives to chlorine gas, the generation of hypochlorite on site has become increasingly common. M65, On-Site Generation of Hypochlorite, presents the principles of on-site generation (OSG), the differences between low-strength and high-strength OSG systems, and the subsequent impact each of these systems has on design, construction, and maintenance for water and wastewater utilities. M65 provides operators and engineering staff with a basic understanding of how to design and install both low- and high-strength OSG systems, how they work, and how they compare with other popular forms of chlorine currently on the market. A cost analysis and an examination of how OSG affects disinfection by-product formation are also included. This manual should help operators, planners, management, and engineers improve their decision-making processes about OSG systems using a holistic risk management approach that considers not only triple-bottom-line approaches but also the specific regional situation when choosing a chlorination system.

Book excerpt: This third edition of M22 contains information needed to estimate customer demand and maximum expected flow that can be used to size new service lines and meters. This edition expands the ways to approach the sizing of water service lines and meters and offers improved methods for the sizing of dedicated irrigation meters. M22 includes a useful field method called demand profiling that can be used to evaluate actual customer use patterns and help optimize meter size selection. The data presented in M22 were obtained from field measurements, utility surveys, technical publications, and hydraulic design calculations. This manual emphasizes that utilities having more information about a specific sizing situation will result in the best sizing decision from the tap to the meter. This information has been condensed into a simplified format to assist readers in addressing most common service conditions. The methods contained in this manual are appropriate for water utility managers, engineers, planners, technicians, field operations personnel, and consultants involved with designing and constructing projects requiring water service.
