The City of Edgewater solicited a competitive sealed‑bid (ITB 18‑ES‑006) for the supply of liquid carbon dioxide, a chemical‑grade CO₂ used in its water‑treatment plant. The City required a minimum of 250 tons per year (up to 400 tons) of CO₂ meeting ANSI/AWWA B510‑00 specifications, with delivery within 48 hours of notification to the Alan R. Thomas Water Treatment Plant. Bids were to be submitted in paper and electronic PDF format by 3 April 2018. One bid was received from Matheson Tri‑Gas, Inc., offering a unit price of $260 per ton, which was deemed responsive and lowest, leading to a council award on 7 May 2018. The contract is a one‑year base period with up to four optional one‑year renewals, price‑adjustable only by CPI‑U (max 5 %) for extensions. Key contract elements include:
• Supply of liquid CO₂ (≥99.5 % purity) with required certificates of analysis and MSDS.
• Firm per‑ton price; no price increase during the base year.
• Delivery within 48 hours of request; $100 per day liquidated damages for late delivery.
