Sanitary Sewer Collection System

Sanitary Sewer Collection System

Chemung County’s wastewater collection system is run by two separate districts called the Chemung County Elmira Sewer District and the Chemung County Sewer District No. 1.

The system contains over 270 miles of sewer mains ranging in size from 2” to 66” in diameter, and 12,000 manholes. Located throughout the city and surrounding area are 33 pump stations that pump wastewater to the plant via six main interceptors. Seven metering stations measure wastewater volume from monitoring points in the collection system.

Our collection system serves approximately 80% of the 35,000 households and over 90% of all businesses in Chemung County. Jointly, they are permitted for 24.2 million gallons of wastewater per day in order to meet current state and federal discharge requirements.
