Oneida County’s complex water system upgrades
At a glance
The Oneida County, New York, Water Pollution Control Plant is under regulatory mandate to increase peak capacity from 55 to 111 million gallons per day to mitigate combined and sanitary sewer overflows in the collection system.
Our response
Managing waste water and collection system upgrade programs is a complex undertaking. GHD’s sewer rehabilitation, separation, and treatment plant expansion and upgrade projects are well coordinated as they consider the many communities involved.
GHD is the prime consultant managing this complex program and led a design team tasked with doubling plant flow capacity on a constrained, active site. The on-going project includes design and construction administration and coordination of the sub-consultant team; and involves approximately 30 separate contracts. The county and city remain on track to meet the ultimate goal of mitigating wet weather overflows. The total cost of the upgrades is nearly $300 million.
