ONEIDA COUNTY, N.Y. -- Oneida County sewer rates are going up thanks to $330 million worth of system upgrades.

Annually, the increase will cost:

• $5.26 for a single-person household (13,500 gallons per year)

• $21.45 for a four-person household (55,000 gallons per year)

• $31.59 for a six-person household (81,000 gallons per year)

Those rate increases have to be approved by the legislature.

The County Executive said it would've been higher, but they're tapping into a reserve fund.

The money is being used for renovations at the Water Pollution Control Plant.

Officials said the infrastructure is aging and work has to be done.

"Without this project, you've got a 60 year old sewage treatment plant that needs major repair. Without this project, you've got Utica that would have to build its own treatment plant for its longterm control plan," said Steven P. Devan, the Oneida County Department of Water Quality and Water Pollution Control Commissioner.

The entire project is expected to be completed in 2021.
