Sewer
Wastewater created by residences, schools, churches, hospitals, businesses, and industrial establishments must ultimately be returned to receiving waters or to the land. It is treated at our wastewater treatment plant that has a treatment capacity of 2.2 million gallons per day. During fiscal year 2021, the Oneonta wastewater plant collected and treated over 366 million gallons of wastewater.
We provide sewer services for the City of Oneonta.
Property owners are responsible for maintaining sewer components located on private property, including:
•The sewer service line from the home or building to the connection with the main line
•Cleanouts located in the yard or near the home
•Grinder pumps or private lift systems (if installed)
•Any plumbing or sewer piping within the property boundary
Important Information for New Homeowners
When purchasing a home, the subdivision developer, builder, or real estate agent should provide information about the location of sewer cleanouts, shutoffs, and any private sewer equipment associated with the property.
If you are unsure where these components are located, you may wish to contact your builder, developer, plumber, or home inspector.
