Underground Oil/Water Separator Repairs & On-Call Services

The Kenton County Airport Board (“KCAB”) will receive bids for Underground Oil/Water Separator Repairs & On-Call Services. Questions are due by 11:59 pm on Monday, May 11, 2026 and answers will be posted no later than Thursday, May 14, 2026 at 11:59 pm. Bids must be received by Thursday, May 21, 2026 at 2:00 pm. No bids will be accepted after that time unless such date or time is extended pursuant to an addendum issued by KCAB.

Background

There are a total of 32 oil water separators installed as part of the environmental system at CVG.  KCAB maintains 20 of these separators.  The separators vary in size, construction, year built and include:

• Underground steel oil water separators
• Cast in place concrete interceptors
• Precast concrete interceptors

In August of 2021, a condition assessment was performed on 17 of the 20 separators. The assessment had a ranking of Good, Fair, or Poor.

Good: The OWS has no visible structural damage or damage to the components. The device appears to operate and function as designed. There is a minimal amount of sediment and debris in the structure. Recommended to be inspected bi-annually.

Fair: The OWS has minor structural damage or minor damage to components. Filters or coalescing plates need to be cleaned but the device is currently functioning as designed. There is a more moderate amount of sediment or debris in the structure. It is recommended to inspect the OWS annually and make repairs as appropriate.

Poor: The OWS has severe structural damage or severe damage to the components. Filters or coalescing plates need immediate attention due to being clogged with sludge and sediment. There is moderate to severe groundwater infiltration from the wall of the tank. The device is not operating and functioning as designed. It is recommended to make the necessary repairs or replace immediately.

In 2025, the 2021 assessment was refreshed, and both assessment reports are attached to this ITB as Attachments A & B.

• Scope of Services —

  1. Oil/Water Separator Repairs

  The successful bidder ("Contractor") must provide services to repair existing underground oil water separators located throughout the CVG campus. All separators have previously undergone inspection and condition assessments. Based on those findings, eight (8) separators, indicated on the table below, have been identified as poor condition and require repair work. The Assessment Reports are included in the Attachments as Attachment A & B for review. Contractor will also be required to provide on-call repair services for all KCAB maintained separators as necessary.

  Separators identified for full replacement will be addressed under a separate future capital improvements project and are not included in this scope of work. If conditions encountered during repair indicate that the separator is beyond reasonable repair, KCAB reserves the right to remove the unit from the repair scope and add it to the future capital improvement project.
