In the Field: Stormwater Treatment at a New Continental Airport Terminal   Water Engineering & Management March 2003
Airports potentially can generate enormous amounts of polluted stormwater runoff. In addition to hydrocarbons such as oil and fuel from cars, trucks and planes, winter weather brings added sand and salt to the roadways. Expanding the terminal area for Continental's new Global Gateway at Newark Liberty International Airport in late 2001 included increasing the paved areas around the terminal to accommodate the new taxiways and roadways. The system demonstrates the effectiveness of applying stormwater treatment technology to an already congested area where competition for space is fierce.

Billing as an Outsource   Water Engineering & Management May 2001   Larry Myers
Natural gas deregulation in Georgia showed marketers the value of outsourcing their billing. This same lesson was learned years earlier by the telecommunications industry. When deregulation for the telecommunications industry became effective, companies quickly realized the need to focus on their core businesses if they wanted to stay competitive. Outsourcing became a sensible way to increase efficiency and cut costs in areas inconsistent with the core business. The smart businesses opted to do what they do best and leave the rest to the experts. These opportunities also are available to the water and wastewater industry.
