Implementing a Watershed Plan for Lake Stevens
The water quality of Lake Stevens is declining because of watershed nonpoint pollution and cycling of nutrients from lake sediments. Hypolimnetic aeration and an alum treatment are proposed...
Design of Aquatic Treatment Systems
This paper describes the design parameters and operating procedures used for a nonpoint pollution/stormwater treatment facility known as an Aquatic Treatment System to be located in the...
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...
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...
The Kettering Community Demonstration Project Non-Point Pollution Control and Environmental Enhancement Program
With the advent of the U.S. EPA's municipal/ industrial NPDES and Coastal Zone Management programs the development of effective non-point pollution control programs has become the most...
Storm Water Management in the Greater New Orleans Area
Two parishes, Orleans and Jefferson, located within the Greater New Orleans area have been identified by EPA as urbanized areas requiring storm water permits. Storm water management has...
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....
Seattle's Storm Water Application
Seattle is considered a large city under the National Pollutant Discharge Elimination System (NPDES) storm water permit regulations and was required to submit a storm water permit application...
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...
Development and Implementation of Stormwater Utilities in Texas Cities
As more Cities begin to understand and feel the financial impact of EPA's Non-Point Discharge Elimination System (NPDES) stormwater regulations on their budgets, many are turning to stormwater...
Storm Water Utility Experience in Bellevue, Washington
Surface water management is seen as a flood protector by most, a savior of the environment by some and a subversion of property rights by others. As recently as 20 years ago, there were...
Case Study: Storm Water Analysis of Manatee Pocket in Martin County, Florida
storm water pollutant loading rates from a 6,000 acre urban watershed were analyzed for source determination of contamination to the receiving water. The receiving water body, Manatee...
Assessment and Mitigation for Endangered Vernal Pool Invertebrates
The USFWS is considering declaring five species of vernal pool invertebrates endangered. Among these are the Vernal Pool Fairy Shrimp (Branchinecta lynchi), the California Linderiella...
Alternatives Analysis Using Two-Dimensional Modeling for the Owensboro Bridge and Approaches
The Federal Highway Administration plans to design and construct a new bridge over the Ohio River near Owensboro Kentucky. A hydraulic model with two-dimensional capabilities was utilized....
Effects of Reservoir Management on Establishment of Riparian and Wetland Vegetation in Northeastern Washington
The effects of various reservoir pool management scenarios on the establishment of riparian and wetland vegetation in arid regions of the Pacific Northwest are discussed. This study quantifies...
Urban Runoff and the Environment
This paper discusses complex water quality problems, including management of urban runoff. Mathematical modelling is used to asses runoff quantity and quality. Environmental impact...
Impact of Spatial and Temporal Data Limitations on the Modeling of Runoff Quantity and Quality
A small subbasin within an urbanized watershed (Reno, Nevada) was intensively monitored for runoff quantity and quality. The EPA Stormwater Management Model (SWMM) was applied to simulate...
