Instrumentation Trends: Increasing Use of Multi-Parameter, Multi-Channel Systems
With the global water instrumentation market projected to grow by 8 percent per year from an estimated $20.8 billion in 2003, increased demand for systems featuring multiple parameters is closely tied to water and wastewater plants' need to achieve operational and maintenance cost efficiencies. Self-cleaning and self-calibrating, real-time instruments require less operational interface, reducing costs associated with human error. In addition, simplifying operation and maintenance requirements for personnel helps reduce training and inventory costs since common spare parts can be used for a multi-channel, multi-parameter system that operates from a common electronic platform.

Arsenic Removal Technology Installed Despite Limited Time and Space
In 2001 Aqua Pennsylvania, Inc., one of the country's largest investor-owned water utilities, began development on the Meyers Tract well system, a new water treatment facility in Collegeville, Pa. Testing on the source wells revealed elevated arsenic levels, measuring approximately 12 µg/L in one well, and about 15 µg/L in the second well. Although these levels did not exceed the 2001 arsenic maximum contaminant level (MCL) of 50 µg/L, Aqua Pennsylvania knew the U.S. Environmental Protection Agency (EPA) would be lowering the MCL for arsenic in drinking water to 10 µg/L in January 2006 and that some type of treatment would be needed if this supply was to remain available to the public.
Finding the best treatment technology to address the problem was just one of the challenges facing the company. To find out how Aqua Pennsylvania chose the best technology for its needs, click on the link below.

Use of Chlorine Dioxide Generation Spreads to Grower Market
Historically, the most widespread use of chlorine dioxide has been in the pulp and paper industry. But it also has proven to be an excellent disinfectant product for washing vegetables. In this application, the ability to kill spores, viruses and fungi at low concentrations is essential, and chlorine dioxide successfully meets those challenges. In addition, it does not affect the taste, odor or appearance of the food it is disinfecting. It is safe to use and complies with food regulations.
Now, Severn Trent Services is bringing this environmentally friendly disinfection technology to the grower market, including its use for greenhouse plants andvegetables. Click on the link below to read more about this new technology.

Unique U.K. Collaboration Highlights Growth of Public-Private Partnerships Worldwide
Public-private partnerships, which have been growing in popularity in the U.S. water and wastewater industry for the past several years, also are becoming more common in other parts of the world. The announcement of such a unique collaboration in November 2004 highlighted the emergence of these partnerships internationally.
Coast to Coast Water Ltd. (C2C), a joint venture of Severn Trent Services and Costain, a U.K.-based engineering and consulting group, has been awarded a contract by the United Kingdom's Ministry of Defence (MOD) to deliver water and wastewater services to approximately 1,500 MOD sites throughout southeast, east and north England. The 25-year contract known as Project Aquatrine is valued at $1.9 billion.
