Corrosion Control Evaluation Service

The City of Columbus Division of Water is soliciting bids for corrosion control evaluation services for the 2026/27 fiscal year, with a due date of August 14, 2026 (today).

The scope covers testing and analysis of corrosion control strategies across 3,600 miles of drinking water distribution mains in compliance with Ohio Administrative Code rules 3745-81-80 through 3745-81-90 and the USEPA Lead and Copper Rule. The contractor must use Metal Samples (a Division of Alabama Specialty Products, Inc.) for supply, cleaning, and analysis of corrosion coupons and tubes. Line Items 1–3 require bidders to establish blanket purchase orders not to exceed a combined total of $50,000 by submitting placeholder bids of $1.00 per item, with detailed pricing submitted separately. The materials are six line items: approximately 240 C1010 mild carbon steel coupons (Part # CO1033750104100), 12 C1010 coupons with specified hole configurations (Part # CO1023750104100), 12 lead coupons (Part # CO1006530004100), 12 copper tubes (Part # SB1024210104100), 12 C1010 steel tubes (Part # SB1023750104100), and one year of cleaning and analysis services. All materials must be pre-weighed, individually packaged in VCI bags, and stenciled with sequence numbers and alloy identification; the City pays all shipping costs. Line Item 6 (cleaning and analysis) requires separate quotations with pricing broken down by coupon and tube quantities. Following analysis, all materials return to the City with corrosion rate analysis sheets.

Detailed pricing for all items must be submitted as an attachment or emailed to rjdunn@columbus.gov. The scope document emphasizes using the same contractor year-to-year to ensure consistent testing methodology for tracking treatment changes and distribution system upgrades.
