Urban Stormwater Runoff Control System?Village of Skokie, Illinois
Combined sewer systems in many communities lack the capacity to convey stormwater runoff from even small to moderate storm. This inadequate capacity, in turn, causes basement flooding...
Storage/Treatment Isoquants for CSO Control Planning
A quantitative procedure which identifies the technically efficient combinations of storage volume and treatment rate necessary to achieve various levels of combined sewer overflows (CSO)...
Combined Sewer Overflow Abatement Planning Based on SWMM EXTRAN Modeling
This paper discusses use of the Storm Water Management Model (SWMM), with the EXTRAN block as the hydraulic transport mechanism, as a tool for developing a facilities plan for abating...
Receiving Water Quality Bases for Evaluating CSO Control Alternatives
Waters receiving combined sewer overflow loadings in the vicinity of Bangor, Maine include the Kenduskeag Stream and the Penobscot River. The city's facilities planning effort was performed...
Application of the Storm Water Management Model in Evaluating Combined Sewer Overflows
This paper summarizes the application of the stormwater Management Model (SWW) to isolate the contributions of Combined Sewer Overflows (CSOs) to a receiving water. The CSO discharges...
Characterizing Urban Runoff Quantity and Quality
A method using simulated flows and measured pollutant concentrations was successfully applied to estimate pollutant loadings resulting from runoff during storm events from an urban area....
Storage of Combined Sewer Overflow: How Effectibe is it Anyway?
The purpose of this paper is to illustrate the importance of modeling long term rainfall records to evaluate the effectiveness of combined sewer overflow storage. This paper will present...
The Fairfield-Suisun Urban Runoff Management Program: The Approach of Small Communities to NPDES Permitting
The Fairfield-Suisun Sewer District is responsible for NPDES permit acquisition and maintenance of the storm drainage facilities of the Cities of Fairfield and Suisun City, California....
NPDES Municipal Storm Water Permit?A Utility Approach
Salt Lake City Department of Public Utilities (SLCPU) is the agency responsible for the operation of the drainage facilities in Salt Lake City. The drainage function is established as...
Continuous Simulation Modeling for Sewer Systems
The peaking-factor method of sanitary sewer design was developed to simplify the calculations in determining design flow rates. This method of analysis is conservative to the point that...
Mitigation of Excessive Wastewater Infiltration/Inflow Effects for US Army Installations
Wastewater collection system on military installations require periodic maintenance and repair, and occasionally upgrading. Deterioration of wastewater systems enables the entry of extraneous...
Proposed Storm Water Management Programs: An Opportunity for Coastal Municipalities to Improve Water Quality
On November 16,1990, the Environmental Protection Agency (EPA) promulgated a final regulation establishing National Pollutant Discharge Elimination System (NPDES) permit application requirements...
Short-Term Effects of the Banjul Sewerage and Drainage Project on Faecal Coliform Counts
Assessment of the short-term effects of the Banjul sewerage and drainage project on faecal coliforms (indicator organisms for contamination of pathogens) in the coastal areas. The project...
Combined Sewer Overflow Abatement by Means of Detention Basins and Stormwater Infiltration
The conventional approach to abate the pollution loads from combined sewer overflows (CSO's) is to include detention basins. The same reduction in CSO loads may be obtained by infiltrating/percolating...
Storm Sewer Analysis & Design Utilizing Hydrographs
In this paper a computer model, designated STORM.HYD, for the analysis and design of storm sewer systems utilizing a hydrograph procedure is presented and discussed. This model which actually...
Sacramento Drainage Manual?Hydrologic Procedures
For a period of over two years, HDR Engineering, Inc. (HDR) and HYDMET have been working with the City and County of Sacramento to develop a Drainage Manual. This Manual contains seven...
Implementation of Storm Water Management Programs in the California Land Development Process
One of the most powerful and encompassing tools for introducing storm water management programs to land development is through California's general plan process. California cities and...
Nitrogen and Phosphate in Vadose Waters in Heber Valley
During the last decade best management practices have been gradually implemented in Heber Valley to maintain and enhance the qualities of surface waters that flow into Deer Creek Reservoir....
Case History: 100-Year Flood Event in San Francisco
San Francisco experienced a 100-year storm in the winter of 1981-2. This is a report of the flooding damage from this event and the actions that the City took to resolve the flooding problems....
Shape Effect on Bed-Load Transport in Pipes
The nature of part-full flows in pipe sewers produces different channel shapes resulting in non-uniform shear stress distribution on the wetted perimeter. New experimental data were utilized...
