PITTSBURGH, PA, June 15, 2011 -- Under two new contracts, Calgon Carbon will supply Sentinel® Ultraviolet (UV) Disinfection Systems at drinking water production plants in the cities of Indianapolis and Fort Wayne, Indiana.

Indianapolis will install 12 Sentinel 12" Systems at its Fall Creek plant to increase protection against Cryptosporidium, Giardia, and other surface water pathogens. When installed in the winter of 2011, the Sentinel Systems will treat up to 44 million gallons of drinking water per day.

Separately, Fort Wayne will install three Chevron 48" UV reactors at its Three Rivers water filtration plant as part of a retrofitting project. The new UV reactors -- capable of treating up to 72 million gallons of water per day were selected because of their low capital and operating costs. Installation is scheduled for June 2012.

Terms of the contracts were not disclosed.

Both Sentinel Systems have undergone third-party validation in accordance with the U.S. Environmental Protection Agency's UV Disinfection Guidance Manual. Both Systems feature UV intensity sensors to ensure accurate delivery of UV dose, an automatic quartz sleeve cleaning system, and a fully automated control system.
