Wireless Sensors Reduce Flooding in Indiana City
Each year, 850 billion gallons of raw sewage overflow into U.S. streams and rivers. If that amount was poured over New York City, it would create a pool 9 inches deep, said Luis Montestruque, CEO of EmNet, a startup designer of wastewater control systems.
Much of the overflow is caused by combined sanitary and stormwater sewer systems, which are prone to floods during storms; the channels for sewage and storm water runoff are only partially separated. South Bend, Ind., one of more than 700 U.S. cities grappling with the issue, is implementing a unique solution to direct sewage and rainwater to unused parts of its sewer system, preventing unnecessary spills.
