The challenge
Veolia North America plays a key role in managing one of the largest wastewater treatment operations under contract in the United States. Our partnership with the Sewerage & Water Board of New Orleans has delivered many benefits over the past two decades, including support for the areas devastated by hurricanes Katrina and Rita.
The project challenges are:
- After a year of studying the viability of an O&M contract with a private-sector provider, the Sewerage & Water Board (S&WB) in 1992 contracted the operation of its two wastewater treatment plants to Veolia.
- With a combined treatment capacity of 132 MGD, the project was at the time the largest under contract in the country.
- Serving a pre-Katrina population of 465,000, the project still remains one of the country's largest, with a combined capacity of 142 MGD (a 122-MGD pure oxygen secondary wastewater treatment plant and a 20-MGD trickling filter plant) as well as a 44 dry-ton-per day fluidized-bed incinerator.
- Under the contract, Veolia's scope of responsibilities includes capital improvements, hurricane recovery, septage receiving and biosolids disposal.
The solution
Innovative solutions:
- Work with the S&WB to plan and supervise a $1.7 million capital improvements program
- Work with regulatory agencies to satisfy their concerns about effluent non-compliance and emissions violations; actions included an intensive technical training program; initiation of process controls and treatment modifications
- Approach increasing incinerator capacity in a way that reduced oxygen generation costs
- Mobilize vast resources from around the country to assist with plant restorations when hurricanes Rita and Katrina struck in 2005
- Take broad range of actions to respond to hurricanes: dewatering and cleaning plant sites, rebuilding control room with modern SCADA system, rehabilitating eight clarifiers, replacing/repairing entire high/medium voltage electrical distribution system, replacing mechanical equipment; and completing repairs to the West Bank plant
