Anchors Aweigh - Part 1   Water Engineering & Management January 2003   Allister W. Thompson
Many pipelines installed underwater are manufactured from synthetic materials such as high-density polyethylene (HDPE) because of the superior corrosion resistance and, in certain applications, the superior wear resistance of synthetics over iron alloys. Synthetic pipelines are used in many tasks for both industrial and municipal applications. As the depths of the installations and the lengths of the synthetic pipelines are increasing, better methods of installations must be developed.

A Common Sense Approach to Design   Water Engineering & Management October 2002   Carter & Burgess, Inc.
When it comes to preliminary designing and engineering of wastewater facilities, it might seem like common sense to have owners and users integrally involved in the preliminary design process, but that is the exception, not the rule. However, some pioneering architecture and engineering firms are changing all of that. Best of all, this process can be applied in the water and wastewater industries.

Revisiting the Selection of Stainless Steel in Water and Wastewater Treatment Environments: Part 3   Water Engineering & Management July 2002   Frederick Bloetscher, Richard J. Bullock, Robert E. Fergen, Gerhardt M. Witt, and Gary D. Fries
Based on the City of Hollywood’s experience, the use of 316L stainless steel should be evaluated carefully due to the potential for problems in the erection and construction of water treatment facilities that will be in contact with high chloride water and/or other corrosive chemistries. As with many membrane facilities, much of the stainless steel is exposed (not buried), which subjected it to atmospheric as well as water quality problems. Therefore, unless the quality control of the raw and reject water (chemical, physical and microbial) can be assured, 316L stainless steel may not be the appropriate material for engineers to specify.

Revisiting the Selection of Stainless Steel in Water and Wastewater Treatment Environments: Part 2   Water Engineering & Management June 2002   Frederick Bloetscher, Richard Bullock, Robert Fergen, Gerhardt Witt, & Gary Fries
Aerobic bacteria (Crenothrix, Gallionella) primarily are encountered in the fresh surface waters, although anaerobic sulfate-reducing bacteria and facultative strains also are encountered. Ground waters are more likely to contain anaerobic and facultative bacteria, as well as Gallionella than surface waters.3 Sulfate-reducing bacteria also are found in seawater.3

Water Intake At New Illinois Power Plant Designed for Variable Flows   Water & Wastes Digest December 2001
The intake system that will draw cooling makeup water from the Kaskaskia River for the $250-million Holland energy plant in Shelby County, Illinois, was designed to balance construction cost imperatives against the river’s variable flow, regulatory requirements and the owner’s operating preferences. The result is a state-of-the-art vital element for the gas-fired, combined cycle plant. As more and more closed-cycle plants are proposed, the concepts that Parsons applied along the Kaskaskia River may provide a good starting point on the drawing boards.

Old Water Line Meets New Technology   Water Engineering & Management March 2001   Tom Gigliotti
The City of Pittsburgh is in the process of a renaissance. Builders must raze the old to make way for the new. In the spring of 1997, the City of Pittsburgh imploded an old building in the center of the downtown shopping district and built the new Lazarus department store. The store’s main entrance is located on 5th Avenue, Pittsburgh’s main retail street. Oliver Avenue, the street adjacent to the new building, is the location of the main water line feeding the new building as well as several adjoining structures.
