Renewing San Diego Pumping Station No. 64
Pump Station 64 has experienced a number of sewage overflows into Penasquitos Lagoon since 1979 (57 in total). The California Regional Water Quality Control Board (CRWQCB) issued a Cease...

Combined-Sewer-Overflow Control in West Germany — History, Practice and Experience

Swirl Concentrators Revisited. The American Experience and New German Technology
The Swirl Concentrator is a small, compact, 'no moving parts' solids separation device. Its function is to act as as a static combined sewer overflow (CSO) regulation...

Toxicant Reduction in the Dunny Way CSO
Combined sewer overflows (CSO) are a source of pollution to receiving waters and need to be controlled. As an interim approach to improving environmental conditions at this site in Seattle,...

Little River: An Investigation of Coastal Environment
Little River is located about 6. 5 kilometres north of Comox on the east side of Vancouver Island. The last major flood in February of 1983 resulted in the river breaking through the beach...

Mechanics of Embankment Erosion During Overflow
Thousands of dams built in the United States have a potential to be overtopped by flood flows. It is necessary to understand the mechanics of embankment erosion in order to evaluate the...

A Review of Overbank Flow Models

Performance of a Deterministic Storm Runoff Model
The paper discusses model comparisons based on a Tulsa, Oklahoma, case study. Modeling strategies were explored, four of which were modeled in detail because of the extremes in range of...

On-Site Microcomputer Control of a Combined Sewer Overflow Diversion Structure
This paper describes the design of an inexpensive system for controlling combined sewer overflows using on-site equipment (raingauges, flow gauges, automatic gates, and microcomputers)....

Inventorying the System/Inspection Introductory Remarks
A major sewer system evaluation survey is nearing completion in the seven communities which make up Special District No. 1 of the East Bay Municipal Utility District. A major effort has...

Eliminating Pollution From Combined Sewer Overflows With Inlet Controls
The problem of contamination of surface waters with storm and sanitary discharges from combined sewer systems has been one of the most difficult problems confronting environmental engineers,...

Los Angeles Infiltration/Inflow Reduction Program
The City of Los Angeles maintains and operates two wastewater collection and treatment systems: the Hyperion System and the Terminal Island System. During the wet months of December through...

Quali-Continuous Simulation of CSOs
Providence, Rhode Island, has a combined sewer system. During and following a precipitation event the capacity of the system may be exceeded and a mixture of wastewater and urban runoff...

Hydraulic Study Requirements for Bulb Type Hydropower Units at a Navigation Lock and Dam
A replacement Lock and Dam at Alton, Illinois on the Mississippi River is presently under construction. This paper presents the results of studies performed for adding six bulb type hydropower...

Chicago's TARP Challenge—8 Million Tons of Rock
The Metropolitan Sanitary District of Greater Chicago (MSDGC) serves 122 municipalities covering 866 square miles in Cook County, Illinois. Of these cities, towns and villages, 53 have...

Analyzing Combined Sewer Overflow Events
The Illinois Environmental Protection Agency/Illinois Pollution Control Board (ILEPA/IPCB) direct that combined sewer system overflows (CSO) be given sufficient treatment including 'first...
