摘要:

Shortly after “Analysis of Water Supply Cost in the Washington (D.C.) Area” by Robert M. Clark et al appeared (JOURNAL AWWA July 1982), the United States Army Corps of Engineers, the mayor of the District of Columbia, and the governors of Maryland and Virginia signed agreements assuring the region of adequate water supply and instream flow into the next century. Regional operation of local supplies, regional sharing of the cost of reservoirs, daily scheduling of upstream releases, and other improvements in the agreement are explained. Also discussed is the technical research conducted for the agreement by the Interstate Commission on the Potomac River Basin (ICPRB).

摘要:

The participants in this discussion—sponsored by the Education Division at the AWWA Annual Conference held in Miami Beach, Fla., on May 18, 1982—pointed out that managers of water utilities in the 1980s must be creative, willing to take risks, and capable of communicating with the public. The panelists also considered ways to encourage management ambitions through training programs and job performance evaluations. Participants were: Patty Eaton, water and sewer commissioner, City of Tulsa, Okla.; Carl Goebel, administrator, Bureaus of Water and Hydropower, Portland, Ore.; James V. LaFrankie, president, American Water Works Service Company, Inc., Hadden Heights, N.J.; Robert C. Marini, president, environmental engineering division, Camp Dresser and McKee, Boston, Mass.; and Edward A. Powers, competency program faculty, American Management Association, New York, N.Y. Kay Kutchins, consultant, Personnel Services Etc., San Antonio, Texas, served as discussion leader. Kutchins is chairperson of the Management Development Committee, which is responsible for coordinating the AWWA Water Utility Management Institute Program at four university management centers. The 1983 institute schedule is: Feb. 20–25, Virginia Polytechnic Institute and State University, Blacksburg, Va.; March 7–11, University of Minnesota, Minneapolis, Minn.; March 13–18, University of Southern California, Los Angeles, Calif.; and April 10–15, University of Texas at Arlington, Arlington, Texas.

摘要:

Boston's aging water system has been inaccurately portrayed as being past the point of no return. The creation of an independent water and sewer commission has helped establish a long‐term capital improvement and system maintenance program that will ensure continued service to some 86 000 customer accounts. By concentrating on three major areas—metering, leak detection, and a relaying and relining program—Boston is expected to reach its goal of having all mains more than 100 years old cleaned and relined or replaced by the year 2000.

摘要:

A comprehensive program for reconstructing the aging portions of the Washington Suburban Sanitary Commission's distribution system consists primarily of cleaning mains and lining them with mortar. This article describes how specific projects are selected, how the work is planned and managed, and how water service is maintained with the least amount of inconvenience to the public during the reconstruction process.

摘要:

Distribution storage systems provide the means to improve and stabilize water flows and pressures, to store treated water during low‐demand periods for peak–demand use, and to meet fire fighting needs or other contingencies. This article describes the types of structures commonly used for distribution storage, discusses how to choose an appropriate structure, and offers suggestions on maintenance.

摘要:

Water tanks require periodic inspection for signs of deteriorating paint coatings and regular maintenance of exterior and interior finishes. Dark exterior colors appear to degenerate faster than lighter colors and also cause more problems with interior coatings because of solar heat absorption. Methods of inspection are described as are procedures for repainting and recoating tanks.
