Energy Efficient Pump Station Operation with a Pump Switching Constraint
Pump operation scheduling has become a significant practical and research concern as utilities increase their computer usage. This paper presents an integer programming algorithm which...
Development of a Phase I Prescriptive Reservoir Model
The U.S. Army Corps of Engineers Hydrologic Engineering Center (HEC) has recently developed a Phase I generalized prescriptive reservoir model referred to as HEC-PRM. The purpose of the...
Usefulness of Low-Cost Watershed Monitoring: A Case Study
A one-year monitoring study was conducted for Harford County, Maryland to identify water quality problems and sources in the 98 mi2 Bush River watershed....
A Chance Constrained Optimization Model Using Kinematic Wave Routing for Stormwater Infrastructure Rehabilitation
A chance constrained optimization model is presented to determine efficient long-term replacement strategies for segments of stormwater drainage systems. The model is multiobjective in...
Cost of Rehabilitation of Water Distribution Systems
The Chester Water Authority was established in 1868 and supplies water to residential and industrial customers in three counties in Southeastern Pennsylvania, and in addition, wholesales...
Infrared Thermographic Sensing of Sewer Pipeline Problems
When a sewer caves in, it often takes the street, sidewalks, and surrounding buildings along for the ride. These collapses endanger public health and safety. Repairing a sewer before such...
Realistic Specifications for Manufactured Sand
Data which demonstrate the beneficial effect of using fine aggregate having high fines contents on concrete properties are presented. All data indicate that the use of a high fines content...
Procedures for Evaluating Aggregate Gradation Specifications
The construction and rehabilitation of transportation facilities annually consumes huge quantities of aggregates. And, the variability in supply and demand for these materials as well...
Proper and Improper Use of Specifications
The contractors have an obligation to the clients to provide a product that meets their requirements. In order to accomplish this, these requirements must be properly translated into the...
Dual-System Cleanup
Engineers designing a ground water treatment system for a manufacturing plant in northern California, found that two systems are better�and cheaper�than one. Most of the ground water at...
An Assessment of Environmental Costs Associated with Crude Oil Pipeline Damage Caused by Earthquakes
This paper presents a methodology for assessing the risk of environmental contamination from oil pipeline leaks caused by earthquakes. Risk is measured both as volume of oil released and...
Dallas Goes Trenchless
Dallas Water Utilities (DWU) has stopped relying solely on traditional open-cut trenching methods. Instead, we look to trenchless technologies to minimize costs and disruption to the public....
Decentralized Wastewater Management
With the discovery earlier this century that city squalor caused disease, we protected ourselves by piping raw wastes away. Later, when the discharge had transformed rivers into foul,...
Snow Fence Operational and Material Testing
The proliferation of snow fence products since the late 1970's presents an opportunity for optimizing the control of drifting snow. It also presents a challenge in discriminating...
High-Level Waste Disposal Regulations: Time for a Change?
Major developments since EPA's high-level radioactive waste disposal regulations were promulgated challenge the validity of some of the assumptions underlying these regulations....
Standardized, Utility-DOE Compatible, Spent Fuel Storage-Transport Systems
Virginia Power has developed and licensed a facility for dry storage of spent nuclear fuel in metal spent fuel storage casks. The modifications to the design of these casks necessary for...
Concept Development of Small Cask to Large Cask Transfer Systems
Studies for EPRI have been performed by two contractors to develop conceptual designs for small cask to large cask transfers of spent fuel. From the work, two dry transfer concepts and...
Rancho Seco Spent Fuel Disposition Strategy
Spent fuel disposition options were studied for the shut down Rancho Seco plant. Based on comparative costs of various options, plant SAFSTOR intentions, reductions of spent fuel handling,...
Economic and Technical Advantages of High-Temperature Processes in High-Level Radioactive Waste Management
The estimated waste management costs incurred for the three principal waste forms produced by reprocessing spent fuel are compared from a theoretical economic standpoint. The cost of vitrifying...
Evaluation of Alternative MGDS Development Strategies
A methodology has been developed to explicitly and quantitatively evaluate acceptable alternative repository development strategies, in terms of the degree to which they are likely to...
