Chlorine Residual Boosting in Distribution Water: Problems with Chlorine Application and Disinfection Byproducts - Part 1   Water Engineering & Management April 2003   Shin-ichi Tokuno
Previous research on the boosting of chlorine residual1 included how to increase low levels of chlorine disinfectants (free and combined chlorine) in the distribution system. Simple bench tests using a pocket photometer showed that there are no problems in boosting the low level of chlorine residual when boosting the same disinfectant to the water (e.g., free chlorine to free chlorine, or chloramine to chloramine). In the boosted chlorine residual, there is no significant instability in decay or dissipation during the time needed (72 hours) after boosting for the small utility distributors.

Municipal Aqueduct System Uses Fiber-Reinforced Polymer Technology for Repair and Strengthening   Water Engineering & Management March 2003   Jay Thomas and Robert St. John
The Providence Water Supply Board faced such a dilemma in 1998 when a major section of a 102"-diameter water line in Cranston, R.I., failed completely. The Providence water line failure raised valid concerns that other sections of the aqueduct also could be prone to failure, since the pipes originally had been installed as long as 50 years ago. Using lightweight, flexible carbon fiber material for strengthening the Providence Aqueduct turned out to be an innovative, cost-effective solution.

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.

Infrastructure Relocation for a Growing Urban Community: Juggling Schedules and Methods   Water Engineering & Management March 2002
In the last decade, municipal leaders of medium-sized cities across the United States have rediscovered downtown urban centers. Economic development initiatives and long-term growth once again focus on these areas. As plans for revitalizing downtown neighborhoods begin to take shape, local governments are finding that existing infrastructures are inadequate to support the utility needs of incoming commercial and residential tenants. As a result, the need for infrastructure rehabilitation and utility service expansion is in high demand.
