Weathering the Storm - Saco Wastewater Treatment Operational and Compliance Monitoring Experience

Incorporated in 1857, the City of Saco, Maine, is on the southern-most end of the Saco River prior to its discharge into the Gulf of Maine. Faced with the challenge of addressing Combined Sewer Overflow (CSO) issues, the City of Saco adopted an approach which involved improving the transport and management of excess wet-weather flows by implementing a scheme that applied advanced vortex technologies for water quality improvement. The application of this advanced vortex technology will be described as a case study including analytical results confirming the efficacy of the system over its two plus years of operation. Additional information will be expounded on the ability of the vortex technology to weather the catastrophic 2007 April Nor-easter.
