Liquid Waste Pollution from a Sugar Cane Industry
The water pollution survey as performed in this study, indicates that all liquid wastes from the mill are segregated. The chemical waste sewerage systems supposedly conveys these wastes...
Evaluation of Tertiary Wastewater Treatment Systems
The purpose of this paper is to evaluate factors affecting the optimum operations of coagulation-flocculation and filtration processes in municipal wastewater reclamation and reuse. Special...
Reusing Treated Wastewater for Irrigation of Raw-Eaten Vegetable Crops in Monterey County, California
The demonstration project was entitled the Monterey Wastewater Reclamation Study for Agriculture (MWRSA). It was principally a field trial study of the feasibility of irrigating food crops...
Procedures in a Change of Water Rights
The general procedures used in the water right analysis for a change in a water right must be applied to the historic use and then repeated for the proposed new use. The required analysis...
Factual Issues in Water Rights Changes
When an appropriator of a water right desires to change the manner in which the right is exercised there are a number of factors that must be considered. These include the types of changes...
A Robustness Constraint for the Analysis of Uncertainty
A sensitivity-based definition of system robustness is presented that can be formulated as a constraint within an optimization framework. The optimization framework permits the tradeoffs...
A Perspective on Performance Variability in Municipal Wastewater Treatment Facilities
Excessive variability in effluent quality can cause wastewater treatment plants to fail to meet their discharge permit limits. This paper summarizes our understanding of the nature, causes,...
Chlorination of Wastewater Treated by Overland Flow
Results are presented from an investigation of the efficiency of three chlorination schemes used for the disinfection of municipal wastewater treated by overland flow. In experimental...
The Reliability of Treatment Systems
The purpose of this paper is to present the results of case studies of zero and first order reactor systems and an activated sludge treatment system consisting of a primary settling tank...
Computer-Aided Analysis of Treatment Plant Hydraulics
This paper describes software for the hydraulic analysis of water and wastewater treatment works. HADES (the Hydraulic Analysis, Design, and Evaluation System,) provides interactive analysis...
Flood Control, Water Conservation, and Urban Change
Los Angeles County has one of the largest, most complex and effective systems of flood control and water conservation facilities in the United States. It includes 14 major dams, 125 debris...
Water Supply Infrastructure Needs: The Evolving Picture
Based on the findings from AWWA surveys conducted in 1983 and 1985, it appears that the earlier conclusion that the needs of the nation's water systems can be met by the local...
Financing Water Supply Infrastructure - A Public Works Perspective
The Massachusetts Water Resources Authority was established to ensure that the regional water and wastewater needs were properly addressed, removing the budget process from the legislature...
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...
Lagrangian-Eulerian Approach to Modeling Contaminants
A Lagrangian-Eulerian modeling approach predicts potential contaminant distributions resulting from the disposal of sewage sludge at the Deepwater Municipal Disposal Site off the northeast...
Facilities Planning in the Caribbean a Case Study
Culebra has significant problems of water scarcity and poor wastewater treatment. In 1984-1985, a formal Environmental Impact Statement (EIS) was prepared for improved wastewater treatment...
Mangement Studies of Farmington Bay, Great Salt Lake
The primary objective of this study is to evaluate management options for the Farmington Bay area of the Great Salt Lake in terms of water quantity and quality. For the study, it was assumed...
Water Resources Strategy - Chicago
Starting in the 1960's, a series of water quality and water resources studies focused on the problems of the Chicago metropolitan area. Some of these studies were among the...
An Optimization Model for Use in Analysis and Design of Wastewater Treatment Systems
The objective of present wastewater treatment plant design is to provide a cost effective processing system for a given waste-water. Generally each of the unit processes is designed to...
The Changing Objectives of Garrison Diversion Unit
Construction of the 101,000-hectare initial stage Garrison Diversion Unit was authorized in August 1965 as a feature of the Pick-Sloan Missouri Basin Program for irrigation and other purposes....
