Solution to a Waterhammer Problem: A Case Study
Waterhammer is caused by a rapid change in the flow velocity of liquid in a pressurized pipeline. Therefore, the potential for waterhammer exists in almost every pressurized liquid piping...
Strategic Planning in Transportation: Uses and Abuses
Strategic planning makes sense because its foundations are in good economic principles. Firms that don't do it are practicing a 'let's live for today'...
Pipe-lining a Pipeline
This core prestressed concrete cylinder pipe is now lining the inside of a major water supply tunnel in Alaska. Occasionally found in rock tunnels, or buried pipelines, large diameter,...
Calaveras Pipeline Hydroelectric Project
The Calaveras Public Utility District (San Andreas, California) has a pipeline connecting its water treatment plant to the San Andreas Reservoir. By reducing the flow rate in the system...
Miramar/Alvarado Hydropower Projects
The San Diego County Water Authority (SDCWA) was organized in 1944 to provide imported water to member agencies in San Diego County. The 24 member agencies supply 90 percent of the water...
Siphon Penstock?An Economic Way to Develop Hydros
As part of the 48 MW Jim Falls Hydro Redevelopment Project by Northern States Power Company, a minimum flow powerhouse was constructed with a siphon penstock. The Minimum Flow Unit (MFU)...
Galt Energy's Inverted Siphon System
Galt Energy Systems' involvement with attempting to standardize the civil component began with studies at small remote sites in Northern Ontario. The system design evolved...
Design of Tension Member Insulated Anchor for Arctic Pipelines
This paper explores the latest development in above-ground waterflood pipe anchors currently being used on the SOHIO operated portion of the Prudhoe Bay Oil Field. The objective of the...
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...
