Council committee clears design contract for Cuyahoga Street storage facility disinfection project
Summary
The Public Service Committee approved forwarding an ordinance authorizing a no-bid contract with Burgess & Niple for design services on a disinfection project at the Cuyahoga Street storage basin intended to reduce combined sewer overflows.
The Public Service Committee moved to place on the consent agenda an ordinance authorizing the director of public service to contract without public bidding with Burgess & Niple, Inc., for design and construction-phase engineering of a disinfection system at the Cuyahoga Street storage facility.
Chris Leto, director of public service, said the project would add disinfection at the Cuyahoga Street basin (formerly called Rack 40), a 9.5-million-gallon storage basin built as part of the city's combined sewer overflow (CSO) program in the early 2000s. Leto said the project is an alternative to building high-rate treatment at the downstream tunnel terminus and is part of the city's request under the CSO consent-decree fourth amendment.
"Our model shows that we overflow about a 100,000,000 gallons in the typical year into the river," Leto said. By dewatering the tunnel at a higher rate and sending flow about a mile north to the Cuyahoga Street basin, Leto said the proposed disinfection would reduce the typical-year overflow by roughly 30,000,000 gallons — from about 90–100 million gallons to around 60 million.
Leto said Ohio EPA has agreed with the city's approach and that the ordinance will allow the city to proceed with design and engineering during construction. Committee members voted to move the item to the consent agenda; no final council enactment is recorded in the committee transcript.
