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...

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...

Near Field Modeling
Results of near field modeling of the wastefield formed by the Sand Island, Honolulu, ocean sewage outfall are presented. Over 20,000 simulations were run with the mathematical model RSB...

No-Dig Gains Ground
The Miami-Dade Water and Sewer Department (MDWASD), the regional wastewater utility of Metropolitan Dade County, is currently undertaking one of the Country's largest Infiltration/Inflow...

Honolulu's Street Relief
Engineers faced the daunting prospect of burying a new relief sewer under a busy Honolulu highway with trench-cut methods. The contractor suggested microtunneling, but the coral reef formations...

An Interception by Boston
Engineers in Boston were recently challenged to design a rehabilitation and replacement for sections of the 60-year-old St. James Avenue sewer system. Approximately 20,000 vehicles per...
