Cost-Effectiveness and Urban Storm-Water Quality Criteria
This paper reviews alternative methods of evaluating the effectiveness of investments in urban stormwater quality improvement. Experience in the related area of control of dry-weather...
Federal Requirements for Storm Water Management Programs
The Water Quality Act has provided the Environmental Protection Agency with the framework for developing a comprehensive storm water management program. The initial phases of the program...
A View from the Middle ? Water Quality Act of 1987: Problems and Possibilites for the Design Professional
Stormwater management has traditionally been viewed as a water quantity concern. The Clean Water Act requirement for future permitting of stormwater discharges will dramatically alter...
A View from the Bottom: Challenges and Prospects
This presentation addresses the Water Quality Act of 1987 (WQA) as it pertains to National Pollutant Discharge Elimination System (NPDES) permits for municipal separate storm sewers. Regulations...
Basis for Design of Wet Detention Basin BMP's
Two different approaches have typically been used to formulate design criteria for wet detention basin best management practices (BMP's). One approach relies upon solids settling...
Long Term Performance of Water Quality Ponds
A report developed under EPA's Nationwide Urban Runoff Program (NURP) describes an analysis methodology and presents graphs and example computations to guide planning level...
Water-Quality Ponds ? Are They the Answer?
Water-quality 'wet' ponds have been proposed to treat storm water for the removal of phosphorous in streams tributary to Cherry Creek Reservoir, a major recreational...
Multiple Treatment System for Phosphorus Removal
Detention ponds, wetlands, and infiltration basins have each been shown to reduce constituent loads carried by urban stormwater, including phosphorus. Design recommendations are presented...
Load-Detention Efficiencies in a Dry-Pond Basin
Inflow and outflow to a dry-pond detention basin in Topeka, Kansas, were monitored for 19 storms during a 14-month period. Samples of runoff were collected automatically at two inflow...
Simulated Water-Quality Changes in Detention Basins
A study has begun to simulate movement of stormflow through detention basins at four locations in the Irondequoit Creek watershed and determine the effect on peak flow and water quality....
Water Quality Study on Urban Wet Detention
This paper summarizes results of a monitoring program conducted on three urban wet detention ponds located within the Piedmont region of North Carolina, in the city of Charlotte. Data...
Swedish Approach to Infiltration and Percolation Design
Design of infiltration and percolation facilities is similar to detention facilities. The storage volume of an infiltration basin being the ponding volume on top of the infiltration surface...
Institutional Aspects of Stormwater Quality Planning
Planning and implementation of programs to control the quality of stormwater runoff in urban areas are carried out within institutional frameworks that directly influence the effectiveness...
Institutional Stormwater Management Issues
Research, innovation, and structure performance are necessary components of an overall stormwater management program, but program success or failure rests on its institutional framework....
Urban Runoff Management?An Industry Perspective An Opinion
Coors presently produces about 17 million barrels of beer per year from a single plant about 15 miles west of Denver. The company chose to keep the responbibility for the quality of its...
Summary of Institutional Issues
The paper presents a summary of three other papers presented at the meeting on institutional aspects of stormwater quality planning. The three papers represented views expressed by representatives...
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...
Source Control of Oil and Grease in an Urban Area
We explored a variety of techniques to remove oil and grease from urban stormwater runoff. Previous work has shown that relatively high concentrations and substantial mass loadings of...
Program to Reduce Deicing Chemical Usage
Over the years (since about 1948), the dependency on deicing chemicals has been increased to provide 'bare pavement' for safe and efficient winter transportation....
Source Tracing of Toxicants in Storm Drains
Sources of toxic chemicals in storm drains are often difficult to locate and even more difficult to control. Receiving environment chemistry, storm drainage maps, land use information,...
