The West Point Story?Chapter 3: An Integrated Park and Treatment Plant
The West Point Wastewater treatment plant in Seattle sits on a small parcel of land that juts out into Puget Sound. In 1984, controversy erupted when Seattle Metro recognized that West...

Upper Guadalupe River Authority, Texas?Innovative Solution to Long-Term Water Needs
Through conjunctive use of groundwater and surface water, the Upper Guadalupe River Authority (UGRA) has designed a water supply system for the City of Kerrville, Texas that saves 80 percent...

The City of Los Angeles Gray Water Pilot Project Shows Safe Use of Gray Water is Possible
A year-long study of eight residential gray water systems was conducted in the City of Los Angeles. Soils irrigated with gray water were compared monthly with soils irrigated with municipal...

Impact of Groundwater Management Act and CAP Water Supply on Agricultural Water Conservation Programs
Irrigation districts in central Arizona have increased the tax assessments for their farms to pay for distribution systems to deliver Central Arizona Project (CAP) water. Many farms must...

Agricultural Water Conservation Programs in the Lower Colorado River Authority
Rice irrigation is the largest application of water within the area served by the Lower Colorado River Authority, accounting for approximately 75 percent of total annual surface and ground...

Optimal State Feedback Estimation in Groundwater: Application to Leaky Aquifers
The problem of groundwater flow in leaky aquifer is looked at from a stochastic point of view. Optimal estimation of hydraulic heads are achieved using Kalman filtering. The Kalman filtering...

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...

Selection of Optimal Best Management Practices (BMP's)
The National Pollutant Discharge Elimination System (NPDES) urban storm water program requires municipalities to remove non-point source (NPS) pollution to the 'maximum extent practicable',...

Urban Runoff Considerations in the Design of Wastewater Management Programs for Coastal Areas
The continuing increase in the population of the nation's coastal areas is placing additional stress on coastal aquatic systems faster than it can be reduced through improved wastewater...

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...

Storage/Treatment Isoquants for CSO Control Planning
A quantitative procedure which identifies the technically efficient combinations of storage volume and treatment rate necessary to achieve various levels of combined sewer overflows (CSO)...

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...

Utilization of Roadway Crossings as BMP's in Urban Areas
Roadway crossings of natural waterways in the urban setting can be used as Best Management Practices (BMP's) by retrofitting existing outlet structures. Pollutant removal is contingent...

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....

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...
