Design of Drainage Pipes Below Landfills
Drainage pipes are an essential component of landfills. Even though their embedment conditions differ substantially from those of pipes for municipal utilities near the ground surface,...
Optimal Design of Water Transmission Mains
Capital cost for constructing a water transmission main includes cost of the pipeline and its associated installation costs. Also included in the capital cost is the cost of a pump station....
Analysis of Alternative Pipe Materials for a Major Public Water Agency
A major southwestern public water agency has historically specified the exclusive use of prestressed concrete cylinder pipe (PCCP) for large diameter water transmission mains. Due to the...
Life Cycle Cost Analysis Discount Rates and Inflation
Life Cycle Cost Analysis techniques are useful for comparing alternatives that have differing cash flows over the expected life of a project. The selection of an appropriate discount rate...
Landfill Gas Pipe Selection and Installation
Sanitary landfills present a unique array of pipe selection and installation criteria when designing landfill gas (LFG) control and recovery systems. Factors that must be considered include...
Twin Pipeline Crossing of the Fraser River
A new creek water supply was developed for the communities of Mission and Matsqui, British Columbia, Canada, in the early eighties. Over 60 kilometres of 450 mm to 900 mm diameter ductile...
Relining of Jordan Aqueduct, Reach 3
As pipelines approach their life expectancy, they may need to be replaced. Or in some instances, replacement is needed much sooner due to defective pipe. Normal replacement operations...
Evaluation and Selection Methodology for Determination of a Preferred Pipeline Alignment
The San Diego County Water Authority (SDCWA) had need to construct a regional 108 to 72 inch (2.7 to 1.8 meter) diameter pipeline through San Diego County to increase water supply to its...
Simulation of Reactive Chemical Transport in a Varying Thermal Field with Reaction-Flow Coupling
A computer program, THCVP, simulates coupling between advective/diffusive solute transport and chemical reactions, coupling of the reactions to heat transport, and feedback from precipitation/dissolution...
U.S. Department of Energy Motor Carrier Evaluation Program
The U.S. Department of Energy-Headquarters (DOE-HQ), Transportation Management Division (TMD) has the overall responsibility to provide a well-managed transportation program for the safe,...
BR-100 Spent Fuel Shipping Cask Development
Continued public acceptance of commercial nuclear power is contingent to a large degree on the U.S. Department of Energy (DOE) establishing an integrated waste management system for spent...
An Innovative Cask for Transporting Defense High-Level Waste
In the early 1980s, the U.S. Department of Energy/Defense Programs (DOE/DP) initiated a project to develop a safe and efficient transportation system for defense high-level waste (DHLW)....
Transportation Legend, Fact and Hysteria or, How to Dismantle a Mature Industry
In the rush to 'correct' the perceived deficiencies in the regulations covering the transportation of radioactive materials, many people, from legislators to...
Planning Model for Sewer System Rehabilitation
A probabilistic model is developed to simulate long-term variation in the structural condition of wastewater collection systems. The effects of both deterioration and rehabilitation can...
Predicting Watermain Breakage Rates
Recent studies on water main breakage have shown significant spatial and temporal clustering in the breakage pattern. The methodology described in the paper provides the basis for a prediction...
Rehabilitation Model for Water Distribution Systems
This paper presents an optimization model for determining the minimum cost rehabilitation and replacement of pipes in water distribution systems. The advantages of the proposed model include...
Urban Drainage Pipe Systems: Failure Diagnosis and Rehabilitation Planning
A Task Committee on Failure Diagnosis and Rehabilitation of Urban Drainage Infrastructure has been organized by the Urban Water Resorces Committee of the Water Resourcs Planning and Management...
The New Generation of Pipeline Rehabilitation
The new advancements in pipelines reconstruction technologies now permit total sewer system rebuilding of collectors, drainlines, manholes, service laterals, and force mains without excavation....
Land Use Considerations and the Siting of Water Facilities
Land uses are an important consideration of water districts in the process of facilities siting. The methodology used to evaluate land use sensitivities in a large pipeline alignment study...
Is There a Future for Vacuum Sewers?
Vacuum sewers collect and transport sanitary sewage using pressure difference rather than gravity as the primary motive force. Compared to conventional gravity sewers, they use smaller...
