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....

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...
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...
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...
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...
Microtunneling with PVC Pipe
PVC is a suitable and economical product for sewer system construction. However, in the past, utilization of PVC sewer pipe in microtunneling was impossible due to axial thrust load limitations...
Flow Study of In-Service Sanitary Sewers Rehabilitated with Insitupipe
In an effort to define the flow characteristics of sanitary sewer segments rehabilitated with Insituform under normal in-service conditions, Insituform of North America, Inc. (currently...
Joint Outfall H Relief Trunk Sewer System
The Joint Outfall 'H' Relief Trunk Sewer System consists of the construction of 11.3 kilometers (7 miles) of polyvinyl chloride lined reinforced concrete pipe varying in diameter from...
Caustic Spray for Sewer Crown Corrosion Control
A novel method to control sewer crown corrosion which involves spray application of a caustic solution to the sewer crown is described. Corrosion control using this concept is based on...
