Computerized Design and Selection of Pumping Systems
Three computer models have been applied in the evaluation, design and selection of a high-lift pump station upgrading program developed for the City of Poughkeepsie, New York. The three...
Forecasting Water Use: A Tutorial
In spite of 4,000 years of public water supply system construction, designs have been customarily based on forecasts of future water use only during the last 100 years. Choices among available...
Optimizing Nonpoint Source Pollution Reduction Costs
This study demonstrates diminishing marginal returns for spending to reduce nonpoint source pollution in Hampton, Virginia. A linear optimization program selected the best combination...
Risk-Cost Analysis and Spillway Design
The NRC's recent report on dam safety proposes risk cost analysis to help select among alternative spillway modifications for existing dams. This paper examines the sensitivity...
Apportionment of Costs for Multi-Party Cleanups
A rational model was developed for allocating remedial response costs among potentially responsible parties involved in clean up of abandoned waste sites. The model takes into consideration...
True Cost Comparison of Landfilling and Incineration of Hazardous Wastes
An analysis of the 'true' costs of a series of discrete model situations representing hazardous waste management by landfilling and incineration was conducted....
Saving Time and Money with Archaeology
In the past 20 years, archaeology has become a necessary part of many engineering projects. However, this aspect of a project is often regarded as an obstacle in terms of costs and time....
Land Treatment of Refinery Wastes
The authors discuss: waste characteristics; land treatment; and cost comparison with incineration....
Operations, Maintenance & Cost Comparisons of Three Dewatering Devices
The Metropolitan Waste Control Commission's Wastewater Treatment Plant in Minneapolis/St. Paul has demonstrated that two new innovative sludge dewatering pocesses, namely,...
Design and Construction of TCE/PCE Removal Facilities
This paper presents a review of the design and construction of a facility in Arcadia, California, to remove trichloroethylene (TCE) and tetrachlorethylene (PCE) from ground water. (Edited...
Denver's Dual Utilization Sludge Management Plan
The Metropolitan Denver Sewage Disposal District No. 1 (District) has adopted a Dual Utilization approach to sludge management. This technique uses composting during periods of inclement...
Innovations in Army Treatment of Remote Site Wastes
The U. S. Army Construction Engineering Research Laboratory (USA-CERL) is currently evaluating new methods for waste treatment at remote sites which will eliminate or mitigate problems...
Foundations in Permafrost and Seasonal Frost
The papers in this volume cover the following subject areas: A method that utilizes a decision matrix diagram for selecting the most suitable and economical foundations for construction...
Roller Compacted Concrete
Roller compacted concrete has emerged recently as an economical material and rapid method of construction for use in gravity dams, overflow structures and heavy duty pavements. The economics...
Proposal for Funding Water Conservation Programs
Programs have been identified which appear to have the potential to conserve significant amounts of water within a large irrigated agricultural area. Losses such as canal seepage, operational...
Evaluation of Cloud Seeding: Southern Great Plains
One of the important aspects of planned weather modification in the United States is that many operational, non-experimental cloud seeding projects have occurred since 1950. Further, several...
