An Investigation of the Supports of a Water Main
Two 48 inch (1. 22 m) diameter cast iron pipes constructed 50 to 70 years ago form a major part of the potable water transmission system of Atlantic City. For the most part of their length,...
Sliplining with Ductile Iron Pipe
The utilization of Ductile Iron Pipe (DIP) as an alternative to be considered for sliplining rehabilitation of sewer pipelines is evaluated. A recent experience in sliplining a failing...
Rehabilitation of Terminal Ballast Water Piping
In order to maintain the integrity of the ballast water piping system at the Marine Terminal of the trans-Alaska pipeline, a composite lining system was installed in the 42-inch (1,067...
Pipeline Infrastructure Rehabilitation
A significant amount of technological development has occurred during the past ten (10) years regarding the actual rehabilitation methods, or reconstruction procedures on the decaying...
Trenchless Techniques for Pipeline Installation, Renovation and Replacement
New construction methods have been developed primarily in Europe and Japan for underground pipeline work. The new methods, known as trenchless techniques, are primarily used when existing...
Monitoring the Effects of the Pipe Insertion Machine Technique
The results of an experimental study of the pipe insertion machine are presented in this paper. Strains induced in an adjacent pipeline, soil displacement, pipe deflection and vibrations...
Water Main Cleaning and Lining?A Utility Perspective
The Chester Water Authority is a regional water supply system located in Southeastern Pennsylvania serving a population of over 140,000 people in two countries and a large industrial complex...
Planning for Rehabilitation?MWRA Waterworks System
The Massachusetts Water Resources Authority (MWRA) operates and maintains 255 miles of large diameter distribution mains. Existing problems include increasing steel pipe repairs and extensive...
Buried Pipeline Research Needs
A workshop was convened with representatives from universities, consulting engineering and research organizations, pipe and/or equipment manufacturers, constructors, users, and government...
Effects of Ground Failure on Ductile Iron Pipe
The design studies and procedures outlined in this paper for pipelines that must cross earthquake fault zones are also applicable to similar ground disturbances resulting from landslides,...
Water Pipeline Infrastructure; Design Now for Future Ease of Repair
This paper covers the general types of water pipe joints presently in the ground in the United States. It also covers the methods used to repair joints and damaged pipes, pipe cutting,...
Seismic Counter-Measures for Buried Pipelines
This paper deals with the seismic counter-measures for mitigating hazards from earthquake damages to buried water and sewer pipelines. To achieve an overall program for the earthquake...
Cable Stayed Bridges
Two of these five papers on cable-stayed bridges deal with wind analysis. One develops the theory for motion due to flutter and reaches the conclusion that the vibrations are, in general,...
Control of Surge Pressures in Irrigation Systems
Excessively high or low pressure within an irrigation system can result in damage to pipelines, pumps, valves, and on-farm facilities. Frequently, these pressure variations are caused...
Underdrain Tube Wall, Perforation Design and OBPA to Minimize Bio-Chemical Clogging
Bio-chemical clogging of underdrains has been most frequently associated with iron deposits (ochre). The underlying sticking agents have been a variety of bacteria and their exudates commonly...
Ultrasonic Flow Meter Testing
Six ultrasonic flow meters were tested in a hydraulics laboratory. Accuracies better than 2% were obtained with two transit-time meters on 14 inch diameter steel tubing. Poorer accuracies...
New Methodology for Determining the Optimal Rehabilitation and Replacement of Water Distribution System Components
A methodology is presented for the determination of the optimal timing for the rehabilitation/replacement of water distribution system components in order to minimize costs. In this model...
Hot Pressing of Lunar Soil and Qualification for Manned Applications
Lunar soil may be fabricated into useful building materials analogous to those used for masonry, concrete and ceramic pipe applications on earth. The process has been analyzed theoretically...
Transportation by Pipelines in Space Colonies
The use of pipelines in space colonies to transport liquid, gas, solids and even passengers is not only feasible but also desirable. For many applications, pipelines offer a number of...
