Curved Sewers: Yes or No?
A study of curved sewer use in Southern California examines sewer design and maintenance of curved versus straight sewers. A telephone survey of personnel in design and maintenance of...
Fast Tracking Milwaukee's Stormwater Cleanup
In building a massive sewer and treatment plant, Milwaukee solved legal and management problems. At the same time, the city speeded design and construction for the project. Triggered by...
Dispersal of Wastewater in the Ocean--A Cascade of Processes at Increasing Scales
An engineering system for marine waste disposal is described. Design decisions are based on broad categories of input information: the complete description of the waste to be discharged;...
Analysis of Partially Filled Circular Storm Sewers
The classic design approach uses Manning's formula. Comparisons between analytical results obtained in this manner and the many available experimental results indicate substantial...
Vacuum Assisted Pipelines Operation
In the process of upgrading the sewerage facilities for Lancaster, Pennsylvania, it was decided to combine two existing facilities into one new facility. This required the design of three...
Temperature Effects on Lasers
While lasers have markedly improved the accuracy of engineering, air temperature gradients can reduce that drastically. Based on a sewer project that used lasers to align all the pipe,...
Infrastructure Crisis: What the Media Are Saying
In the past year and a half the national media have performed the major role in spreading the word that the nation's public works, particularly in urban areas, have been neglected...
Boston Tunes Up Water System
