Design Alternatives for Protection of the Santa Ana River Interceptor Sewer
The Santa Ana River Interceptor Sewer (SARIS) line buried within the floodplain of the Santa Aria River is being threatened by long term degradation of the river bed at the pipeline crossings,...
Water Quality Modeling of the Rouge River Watershed
A relatively detailed modeling framework for calculating pollution flows and loads to the Rouge River has been developed and tested successfully. The framework includes consideration of...
Preparation of Notification Models Using Continuous Modeling Techniques
Public health departments in many states now require that operators of collection systems notify them of discharges from combined sewer systems soon after these events occur. This allows...
A New Strategic Management of Pumping Station in Sewer Systems
Pumping stations are literally the heart of most sewer system operations and sewage treatment plant processes. Current studies show that a small improvement of pump efficiency will offer...
Best Management Practices and Community Education
The 1987 Water Quality Act requires the permitting of municipal separate storm sewer systems and the reduction by permittees of the discharge of pollutants in stormwater to the maximum...
Volunteer Organizations Use of Appropriate Technology in Developing Countries
The water and sanitation needs facing developing countries are formidable. This paper discusses the experience of a volunteer organization, the Water and Sanitation Consultancy Group,...
Comparison of Worst-Case and Probabilistic Approaches to Ocean Outfall Mixing Zone Analysis
Two approaches have been used for ocean outfall mixing zone analysis: worst-case approach and probabilistic approach. This paper discusses some advantages and disadvantages of the worst-case...
Physical Modeling to Determine Head Loss at Selected Surcharged Sewer Manholes
The head losses at sewer pipe junctions (manholes) under surcharged conditions were measured in a 1:6 scale model of a typical manhole with one main line passing through it and two perpendicular...
