County staff seeks bids to replace deteriorating cast‑iron jail plumbing; vents identified as immediate priority
Summary
Contractors told the council the jail’s cast‑iron sanitary and vent piping is internally corroding and causing backups; staff will prepare a scope of work to bid an above‑ground vent replacement (estimated in the low hundreds of thousands) and may add underground sewer relining as a separate preventive project.
Adams County staff alerted the council to widespread deterioration of cast‑iron sanitary and vent piping in the county jail and said they will develop a formal scope of work to bid repairs, starting with above‑ground vent stacks that officials described as the immediate priority.
Why it matters: County facilities staff and contractors told the council that internal corrosion of cast‑iron piping is flaking into sanitary mains, causing repeated blockages and backups at the jail. The county’s contractor recommended replacing cast‑iron with PVC for a long‑term fix and suggested lining some stacks to preserve the jail roof membrane.
What contractors told the council: Marty Kane of Hattersley said the jail’s cast‑iron sanitary piping is "internally, corroding and flaking off" and recommended replacement with PVC. Justin from Pipeline Pipelining described lining options for underground or roof‑penetrating stacks. Kane said replacing exposed vents and accessible above‑ground cast‑iron components could be done in phased shutdowns to avoid closing the facility; he estimated the minimum plan for above‑ground work at "probably 300,000 or more."
Scope and sequencing: Staff described options: (1) replace above‑ground cast iron and vents with PVC; (2) line vent stacks where roof work would otherwise endanger the roof membrane; and (3) consider relining underground sewer lines as preventative work while contractors are mobilized. County staff said the vent stacks are the priority because clogged vents are causing the backups; underground relining was described as preventative and could be scoped separately.
Warranty, diagnostics and lifecycle: Contractors discussed manufacturer and ASTM standards and said their products are warranted for 50 years for properly installed systems; contractors advised running a camera inspection on underground pipes before committing to full excavation. Staff also noted that hard water and sediment have stressed pumps and water heaters and that a recently installed facility water softener has reduced but not eliminated the effects of scaling.
Funding and next steps: Staff said the project will require a bid package and commissioners’ approval to advertise and appropriate funds; the county plans to use the contractor presentations to prepare that scope. County staff said they will return with bids or formal estimates; they did not request immediate appropriation at the meeting.
Ending: County staff told the council they expect to return within two months with a formal bid scope and estimates for commissioners to consider; the council was asked to receive the report and await a formal appropriation request once firm bids are obtained.
