EmNet LLC, a startup designer of wastewater control systems, has completed a pilot project here that could save municipalities around the world millions in infrastructure improvement costs and prevent combined sewer overflows.

The company, which received a more than $1 million grant from Indiana's 21st Century Research and Technology Fund in 2007, has developed a wireless technology that acts as a traffic signal to electronically direct and control the flow of wastewater through underground pipes and retention ponds linked to a municipality's existing sewage and storm water infrastructure.
