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.
