Public Water Supply Distribution Systems
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309096286
Category : Science
Languages : en
Pages : 57
Book Description
The Water Science and Technology Board has released the first report of the Committee on Public Water Supply Distribution Systems: Assessing and Reducing Risks, which is studying water quality issues associated with public water supply distribution systems and their potential risks to consumers. The distribution system, which is a critical component of every drinking water utility, constitutes a significant management challenge from both an operational and public health standpoint. This first report was requested by the EPA, as the agency considers revisions to the Total Coliform Rule with potential new requirements for ensuring the integrity of the distribution system. This first report identifies trends relevant to the deterioration of drinking water quality in distribution systems and prioritizes issues of greatest concern according to high, medium, and low priority categories. Of the issues presented in nine EPA white papers that were reviewed by the committee, cross connections and backflow, new or repaired water mains, and finished water storage facilities were judged by the committee to be of the highest importance based on their associated potential health risks. In addition, the report noted that two other issues should also be accorded high priority: premise plumbing and distribution system operator training. This first report will be followed in about 18 months by a more comprehensive final report that evaluates approaches for risk characterization and identifies strategies that could be considered to reduce the risks posed by water-quality deteriorating events.

Assessment of Auxiliary Backwash Method for Rapid Sand Filters
Author: Richard C. Pohlman
Publisher: American Water Works Association
ISBN: 1583214356
Category : Technology
Languages : en
Pages : 84
Book Description
The primary objective of this project was to determine differences in filter effluent water quality and media cleanliness between sand filters employing air scour and those employing surface wash. Discussed in detail are the findings that scour and surface wash systems performed similarly relative to filter effluent quality and filter cleanliness. The advantages of one system over another can be site-specific particularly in retrofit applications.

Upgrading Wastewater Treatment Plants, Second Edition
Author: Glen T. Daigger
Publisher: CRC Press
ISBN: 9781566766449
Category : Technology & Engineering
Languages : en
Pages : 272
Book Description
FROM THE PREFACE In this time of dwindling budgets, increasing service needs, and increasing regulatory requirements, wastewater treatment professionals are continually called upon to upgrade their wastewater treatment plants. To do so efficiently and effectively, one must develop a clear approach to use in upgrading a plant and have the proper tools available to implement that approach. This book is meant to assist readers in developing and implementing their upgrading projects. First, Chapter 1 details the upgrading approach. The tools to be used are presented in Chapters 2 through 6. Finally, in Chapter 7, six case histories are presented to illustrate the plant upgrading techniques presented in the previous chapters. Through this book, the authors hope to assist readers in meeting their upgrade requirements, while making the most efficient use of the resources at hand.
