The estimated budget for this contract can be based on the estimated annual usage of each chemical. The total estimated annual usage is: 950,000 lbs of Ferric Chloride, 500,000 lbs of Sodium Hydroxide, 50,000 lbs of Polymer, 30,000 lbs of Zinc Orthophosphate, 50,000 lbs of Calcium Thiosulfate, 15,000 lbs of Sulfuric Acid, 10,000,000 cu ft of Liquid Oxygen, 25,000 lbs of Hydrofluorosilicic Acid, and 60,000 gal of Sodium Hypochlorite. Assuming an average cost per unit, the total estimated annual cost can be calculated. For example, if the average cost of Ferric Chloride is $0.50 per lb, the total estimated annual cost for Ferric Chloride would be $475,000. Similarly, the total estimated annual cost for each chemical can be calculated, and the total estimated annual cost for all chemicals would be around $2 million to $5 million. The total budget for the 10-year contract would be around $20 million to $50 million.
