Anchorage Taps Eklutna Lake for New Water Supply
The 170 million Eklutna Water Project will furnish water to Anchorage, Alaska by the summer of 1988. The project consists of an 8,500-foot long diversion tunnel, 6 miles of 54 to 60-inch...
An Overview of Cold Region Considerations for the Design of the Eklutna Water Project
The paper presents a brief overview of cold regions considerations that were considered during the design of the various elements of the Eklutna Water Project in Anchorage, Alaska. The...
Alyeska Reroutes Trans-Alaska Pipeline at MP 200
This paper discusses the 1985 wintertime repair/reroute to the Trans Alaska Pipeline System (TAPS). The rerouted pipe was approximately 4000 feet long and cost approximately 27 million....
Systems Model for Water Supply Following Earthquakes
The water supply for San Francisco is described with emphasis on the city's auxiliary water distribution network, which provides fire protection for the most heavily built-up...
Earthquake Risks to Utah Water and Gas Systems
Designed to guide local earthquake hazard reduction programs, this study estimates direct aggregate earthquake damage to Davis and Salt Lake County utilities. For making these loss estimates,...
The Effects of the 1985 Mexico City Earthquake on Underground Water & Sewer Pipelines
The 1985 Mexico City Earthquake left thousands dead and many thousands more without shelter. The visible damage was immense and terrible, and familiar to people around the world through...
The Pacific Texas Pipeline Project?Deepwater Oil Terminal, Port of Los Angeles
This paper describes the implementation program and status of the Pacific Texas Pipeline Company project in the Port of Los Angeles. A brief description of this important 1. 6 billion,...
Sulfide Corrosion and Control in the City of Modesto Primary Effluent Outfall (
The City of Modesto has a 60 inch diameter, 6- one-half mile long reinforced concrete pipeline conveying primary effluent from the primary treatment plant to the remote oxidation pond...
Gas Transfer and Secondary Currents in Open Channels
Laboratory flume experiments on water-wide controlled gas transfer, such as reaeration, are described. The experiments indicate that gas transfer is a surface renewal process, well described...
Oxygenation of Releases from Richard B. Russell Dam
The oxygen injection system at the Richard B. Russell project has a continuous injection system located 1 mile upstream of the Russell damsite but also has supplemental injection capability...
The United Kingdom Approach to Rehabilitation
Following concern over the condition and performance of its underground assets, the UK Water Industry has developed strategies for cost effective sewer and water main rehabilitation. These...
Hydraulic Reliability of Urban Water Distribution Systems
Conventional planning and design approaches for urban water distribution systems consist of trial and error procedures to select piping network configurations, pipe sizes, storage capacities...
Model for Optimal-Risk Based Water Distribution Network Design
Various models using a variety of optimization techniques were developed for determining pipe diameters, network layout, pump capacities, and other design parameters. The objective function...
A New Methodology for Modelling Water Pipe Breaks
A new methodology for modelling breaks in large diameter cast-iron water pipes is proposed. The need to consider two separate stages of deterioration (early stages with fewer breaks and...
Grand Canyon Water Line by Directional Drilling
The South Rim Village at Grand Canyon National Park obtains its water supply from a point called Roaring Springs which is located approximately 15 miles across the Canyon on the North...
Taming a Pipe Network Analysis Computer Program
The use of a conventional network analysis computer program as an effective evaluation tool for routine operation of an existing water distribution system has several practical limitations...
Guidelines for Maintenance of Aging Water Pipes
Break failure patterns are investigated by applying a new methodology based on Proportional hazards and Poisson-type models. Application on two water distribution systems of North-Eastern...
