Nationwide Urban Runoff Program, USEPA (United States Environmental Protection Agency), Lansing, Michigan. Evaluation of Urban Stormwater Runoff and Management Practices for Controlling Urban Stormwater Runoff - Final Report

摘要

This volume documents assessment of an on-line retention basin, two in-line up-sized storm drain pipe reaches, and an off-line detention basin as treatment techniques in mitigating the pollutant impacts of urban runoff, as well as the operating costs associated with such installations. The on-line retention basin was found to be very effective in treating a wide range of rainfall amounts and pollutant loads. The in-line up-sized stormdrain pipes displayed variable effectiveness depending on rainfall amount and runoff volume. The off-line detention basin had little or no effect on water quality.
